Light travels at the speed of sound. That is because photons, which are massless particles, travel at the speed of light. The speed of light is so high that it breaks causality between things. As a result, the time of an object approaching the speed of the light increases. It is impossible to calculate the amount of time that a particle would take to reach the same location. Fortunately, it is possible to estimate the duration of a particle at a distance close to its travel speed.
When objects move at the speed of light, they cannot travel faster. Their mass and inertia increase with the speed of the object. The greater the mass of the object, the more energy it requires to accelerate it. In contrast, lasers travel at speeds much higher than the speed of light. It is therefore possible to measure the distance between two points at the same time and see the distance between them. This fact explains why light is so fast in certain cases.
It is possible to determine the speed of light by looking at the speed of the individual particles in a system. This is done using the concept of wavelength. Since wavelengths are measured in millimeters, this means that light travels in a sphere at the speed of light. However, it is possible to measure the distance between two points, if you know the exact distances. This is a great advantage if you are trying to calculate the speed of the object at the target.
If Youre Moving Faster Than the Speed of Light, What Would Light Look Like?
The question of “If youre moving faster than the speed of light, what would light look like?” is one that boggles the mind. It is difficult to comprehend, but Einstein tried to come up with a simple solution. Essentially, he assumed that light travels at the same speed in all directions, no matter how fast you are going. This theory proved that the idea is absurd, but there are some interesting side effects of a spacecraft’s design.
If you’re moving faster than the speed of light, how would you see light? The answer to this question is a complicated mathematical formula that relies on relativity. The speed of a sphere at 95% of the speed of the sound we call light is an ellipsoid. It is a circular shape when measured, and a zeppelin when calculated nonrelativistically.
Einstein’s Special Theory of Relativity was born out of a schoolboy’s question. This equation explains that the speed of light is a constant. Thus, if you were moving faster than light, what would the light look like? The answer to this question will surprise you. If you’re moving faster than light, it’ll look distorted. As you move, your view becomes brighter, while objects behind you will come into view. If you’re moving slower than the rate of the sound, however, you’ll still have the same image.
What is the Speed of Light Relative to Me If I Am Travelling at the Speed of Light?
If I am travelling at the speed of light, what is the speed of light relative to me? The answer depends on what you consider a’speed’ to be. Using a scale, we can work out the relative speed of an object and an airplane. The distance between a plane and an airplane is measured in miles per second, but the plane’s distance from the ground is measured in kilometers per second.
Light travels at a constant speed of 1,07 billion km/h, which is equivalent to 299,792,458 m/s or 670,616,628 mph. At this speed, we could travel around the earth in one second. It would take 50 hours to circle the earth if we flew at 800 km/h, the speed of light.
To find out the speed of light, we can use the NIST’s reference for units and constants. The reference provides more information about uncertainty. A good book on the subject is Jespersen and Fitz-Randolph’s 1999 Understanding Time. Mermin and David, N. 2005, It’s About Time, and Lawrie, ID (2002), A Unified Grand Tour of Theoretical Physics.
What Would the Universe Be Like If the Speed of Light Were Infinite?
An infinite speed of light would negate Einstein’s theory of relativity. It will take an object an infinite amount of energy to move through space at any speed. There is no way an object could travel faster than the speed of the light, but an endlessly slow object might make interesting observations. Fortunately, the speed of light is only a fraction of the universe’s speed.
The speed of light is the limiting factor in the expansion of the universe. We cannot go faster than that. But what if we could reach the speed of light in a vacuum? That’s impossible. We’d need an accelerated particle to travel faster. That means time would slow down. The acceleration of a particle in a high-speed environment would be so great that the particles’ speeds would be nearly identical.
The answer to this question isn’t easy to determine, but it’s still an important question to consider. The answer to this question depends on what you believe about the nature of light. If light is infinitely fast, it would be impossible to travel at the speed of light. But that doesn’t mean that the universe is unstoppable. There’s no way of knowing how far light can travel if it were moving at an infinitely slow pace.
Why Does Light Travel So Slowly?
If you’ve ever wondered why light travels at a very slow rate, then you are not alone. In fact, NASA scientists have produced a series of simple animations to prove the point. The first one shows how long it takes for light to travel around the Earth. The next two are animations that show how long it takes for light to travel from Earth to the moon and from Earth to Mars. In a vacuum, a particle of energy traveling at the speed of sound moves at about 186,282 miles per second, or 670.6 million mph, or 1.079 billion km/h.
Despite this slowness, scientists have been puzzled by the question of why light travels so slowly. The answer is complicated, but it is actually very straightforward. In a vacuum, light moves at 299,792 kilometers per second. In other words, it takes a long time to travel from one place to another. The speed of light, however, is only a measure of the distance a signal can travel in a given time period.
The first clue came about 150 years ago when a Scottish physicist, Ole Romer, discovered that a single photon can travel 186,282 miles (or 298,792 km/h) at the speed of light. In his calculations, he found that the particle’s speed was exactly equal to the speed of light. This result strongly suggested that light is an electromagnetic wave.
Is it Possible for Humans to Ever Travel at Or Near the Speed of Light?
There is an interesting video made by NASA about near-light travel. This demonstrates that we can travel at the speed of light. The time taken to travel from Earth to another planet would be shorter than that of traveling at the speed of light. Furthermore, the earth’s clocks would also continue to move at the standard rate. The possibility of human space travel is exciting.
In fact, this kind of technology is already on the way. A particle of light can cover 380,000 kilometers in 1.3 seconds. If we tried to travel that far, it would take us nine years of walking! However, the more mass we have, the more energy it takes to accelerate our body. To achieve the speed of light, we would need an unlimited amount of energy.
It’s important to remember that when two quanta interact, momentum and energy are conserved. In fact, the physics of a system of particles moving forward in time is identical to that of a system of particles reflected in a mirror. In other words, nothing can travel faster than the speed of light. So, if we want to travel at or near the speeds of light, we need to reach these speeds.
Why Doesn’t Light Annihilate Everything With Which It Comes in Contact?
The answer lies in the fact that the angular momentum and energy of a particle can’t be affected by its environment, unlike in the case of an atom. An atom can change its mass as long as it’s not surrounded by matter. It is impossible for light to interact with a body, because it’s a dipole.
One of the main reasons for this is because light doesn’t have rest mass. While matter has energy even when it’s in a stationary state, photons have no rest mass. Unlike electrons, photons don’t obey the laws of exclusion, which require two different quantum numbers for two particles to be able to interact. Furthermore, because they can’t be weighed, photons can pack any volume bigger than their wavelength.
Another reason is that photons don’t have rest mass. While matter is mass when in motion, light has no rest mass. Since light is a boson, it doesn’t follow the laws of inclusion and exclusion. This means that it can’t be merged with an electron, so its energy can’t be transferred to the electron. However, this difference does not mean that photons aren’t able to combine with a particle because they’re in different energy states.
The Speed of Light – Why is it So Easy to Stop?
Scientists have long wondered if the universe is infinite. If it were, light would go on forever, and it would be impossible for it to stop. In contrast, there are two main types of universe: a compact and an infinite one. The latter is defined by a mathematical term called topology, which is the symmetry and shape of the universe. When light encounters a material, it will bend, causing a decrease in speed.
The speed of light is extremely high. Its wavelengths vary according to its energy, and its speed depends on the medium it is in. Since it has no mass, it can travel through different mediums and stop at any time. However, the only thing that can arrest it is gravity. If you can see or touch light, you can easily catch it and use it as an example of how to stop it.
Light has no mass, so stopping it is very simple. At its fastest, it flips through space-time, and at the same time breaks the law of causality. Therefore, as it reaches the speed of light, it is very easy to stop it. As it gets closer to the speed of the light, the amount of mass it has increases. This makes stopping light easier.
Why Does the Universe Want to Preserve the Upper Barrier on Speed of Light?
Einstein did not include this statement in his Special Theory of Relativity, but it was made long before. A few years after Einstein’s announcement, French physicist Henri Poincare wrote that matter cannot travel faster than the speed of light. This restriction on particle speeds is even stricter in our Universe, where there are countless unknowns.
The speed of light is the fastest thing that we can observe in the Universe. If we were to observe a particle traveling at a normal speed, it would be accelerating at the same rate as the light. But, when we travel at a speed of 186,000 miles per second, the particle is effectively standing still. In fact, the researchers claim that this is the most convincing demonstration of the speed of the electromagnetic spectrum.
A fundamental question that has been lingering for decades is why the universe would want to preserve the upper barrier on the speed of light. The answer to that is the answer to the question, “why does the universe want to preserve the upper barrier of light?” A common question is why the universe would want to keep the barrier at a low level. But that doesn’t mean that it doesn’t want to break it.
The Fundamental Reason Why the Speed of Light Cannot Be Broken
It’s not a mystery that the speed of light is the limit of all travel, even in our most advanced technology. The speed of light is a fundamental property of our universe, and scientists have worked out that faster travel would shrink the spatial dimension and slow down the clock when observed from an outside observer. The problem with this model is that the universe doesn’t exist in a vacuum; time and space are not fixed background conditions.
Moreover, time and space would be invariably slowed down as we get closer to the speed of light, but once we reach that speed, time and space stop. In fact, the speed of light is infinite, from the photon’s point of view. This is an important aspect of our understanding of how time works, but we must also keep in mind that the speed of light cannot be broken.
Although the speed of light has been measured with extreme precision, it has remained elusive throughout history. Many experiments were carried out over the centuries to play with the phenomenon, but they failed to show it could be slowed down. The light travels at a rate faster than the observer, whereas light in a vacuum is moving at an almost constant rate. Thus, even if light travels faster than the observer, it cannot break this basic principle.
What is Faster – The Speed of Light Or the Speed of Darkness?
Light travels at the speed of the sun. However, dark matter should have a slower speed. A shadow moving at the same rate as light moves at the same speed is called a wormhole. If a wormhole exists, then dark matter would move at the same rate as light. If you were to travel through a wormhole, you would get to your destination in a matter of minutes.
When light is traveling at the speed of light, the speed of darkness is equal to the distance between two points. When an object blocks a beam of incoming light, it creates a dark spot. This dark spot travels at the same rate as light traveling without any obstruction. If this is true, then the speed of darkness is the same as the distance between the two points. Therefore, light travels at the same velocity when it is obstructed.
Another scenario in which darkness travels at a faster rate than light is the formation of a wormhole connecting distant points. In this scenario, the travel time from point A to point B would be very fast and the time needed to reach the destination would be very short. The speed of dark is considered to be negative, but if you’re observing something outside the wormhole’s field, the dark is approaching from behind.
Why is the Speed of Light So Close to 300000?
Why is the speed of light so close to the 300000? This question was first asked by Albert Einstein in 1905. The experiment was to measure the speed of light, which is three million kilometers per second. The experiment proved that the same velocity is achieved with a moving source as a stationary one. As a result, light from a supersonic jet, a lighthouse, and even a car travelling at a fast rate has a constant velocity.
The answer lies in the fact that Einstein’s Special Theory of Relativity explains how the speed of light doesn’t change when a light source moves. His experiment revealed that the headlight of a car always moves at the same speed. Thus, light from a stationary source travels at the same speed as a moving one. That’s why the speed of light is so close to 300000 km/s.
The constant, c, is what defines light in physics. Although it’s the fastest moving thing in the Universe, it’s not a true constant. It is the maximum speed for massless particles in a vacuum, which is why Maxwell could calculate the speed of light without knowing the exact value. In other words, light can travel anywhere. This makes it possible to measure the distance between two points from any point in the Universe.
Why Can’t We Travel Faster Than Light?
The question of why can’t we travel faster than light is often raised. Basically, Einstein’s theory only applies to a vacuum. In reality, light can only travel at a slower speed in a vacuum than it does in a physical medium. If we want to travel faster than the speed of sound, then we need to leverage Einstein’s theory of general relativity. In other words, we need to be able to move at a higher speed than light.
It turns out that light travels at the speed of light. That’s an amazing feat, but it’s not possible right now. A person would need nine years to travel that far. As the speed of light increases, the mass of an object also increases. And since we can’t store energy, we can’t travel faster than light. This is the reason we cannot travel faster than the speed of sound.
The speed of light is defined by the speed of light. Its maximum velocity is 240,000 mph (or 380,000 kilometers). To travel at the speed of light would take a person nine years to do so. Similarly, if we wanted to go faster, we would need infinite energy. But that’s not possible. So, we can’t travel faster than the speed of sound. The only way to do that is to make a machine that can achieve such a speed. Why is the Speed of Light So Small Relative to the Size of the Universe?
The answer to this question is very complex. First, you have to realize that the speed of light is a velocity, not a mass. The universe is 3.3 billion light-years in diameter, which is 67 times smaller than the Earth’s mass. Then, you must know that the size of the universe is not known until you know the speed of light.
The speed of light is independent of the distance from a point in space. If we are in a vacuum, all light waves are traveling at the same speed limit, even if they move away or towards a light source. Similarly, if we move toward the source of light, we would experience a redshift in the wavelength. Therefore, the speed of the light will never change when we are in the vacuum of space.
The speed of light is not proportional to the size of the universe, and it is also independent of the direction of motion. In a vacuum, all light waves travel at the same limit, and their wavelengths are unchanged regardless of their direction. That means that even when moving away from a light source, light rays always travel at the same rate. This fact is important because it allows us to calculate the speed of light from distances of a few hundred miles.
The Speed of Light – The Universal Speed Limit
The speed of light is the fastest particle of light in a vacuum. It is the universal speed limit. However, this rate is not constant due to the finite amount of time and space. In addition, this speed is affected by a variety of physical laws. Hence, it is not practical to travel at the speed of a single particle at a time. This fact makes it impossible to travel at speeds exceeding the speed of light.
The speed of light can be defined as the maximum speed of a massless object. According to Einstein, all particles with mass can approach this velocity. If a material object were to try to travel at the same rate, it would require infinite energy. Therefore, there is no way for a massed object to reach the speed of light. If a material object were to reach this limit, it would have to reach the velocity of light in order to get anywhere.
The speed of light has a fundamental limit. It is a fixed limit set by the laws of physics. In the early modern period, no one was aware of this limit. But scientists eventually came to realize that the speed of light is the ultimate limit of any material object. In other words, any object or energy that can move faster than light cannot move any faster than light. The result was the development of the theory of relativity.
What is Stopping Light From Going Any Faster?
It’s impossible to travel faster than light. In fact, the speed of light is infinite, and nothing can go faster than it. This fact is fundamental to the universe, since a particle traveling at the speed of a photon cannot experience time. Also, there’s no mass in light, so nothing can go faster than it. The answer to this question is infinity plus one, which is the speed of the sun.
In the first place, we can see that light travels rapidly. This is evident by turning on a light switch. We can also see that light travels at a fixed speed, which is 300 million meters per second. The speed of light remains constant regardless of the relative velocity between the source and the observer. That’s because the relative motion changes the relationship between time and space intervals, and this change in the speed of light has no effect on this.
A more precise estimate came from Michelson, who used a helium balloon to flash a beam of light between two mountain tops and compared the distances to obtain an accurate estimate of the speed of light. Another method was used by Leon Foucault, who set up a mirror at five miles away to reflect the beam back to the source. These two methods both came within a thousand miles per second of the speed of c.
The Universal Speed Limit is the Speed of Light
The speed of light is a constant set by the laws of physics. The universal speed limit of light is the same for all matter in the Universe, and it is 299,792,458 meters per second (186,282 miles per hour) for the light particles. As light never changes, it is a perfect reference for speed measurements. It appears that all objects move at the same rate, and matter is only able to approach this speed.
The speed of light is the only known speed limit in the universe. There is no limit on what can be moved in space, so we cannot go beyond it. It is the basis of modern physics. It states that matter has a finite mass until it reaches the speed of light. As it approaches this limit, its mass is infinite. The speed of light is immutable, and it is used to define international standard measurements, such as the kilogram and the Kelvin temperature units.
A cosmological model that describes the speed of light in a vacuum predicts that light travels at 186,000 miles per second. A new study shows that this is a much higher value than previously thought. It has also shown that space and time are infinite. The only way to know what that limit is to test the theory. Observations of space and time will always show the same speed as light.
Why is Light Faster Than Sound?
The speed of light is the fastest known physical phenomenon. It is a mechanical disturbance that travels through a medium. In the absence of a medium, the speed of sound depends on the type of medium. When something moves at a high speed, air molecules bounce around, disrupting the direction of motion. As a result, sound travels as a pressure wave. It also requires a specific medium to transmit and receive information.
The speed of light is measured in terms of the speed of the sound wave in air. The velocity of light is 343 m/s. As a result, light travels at three times that rate. Since light doesn’t travel through a medium, it can travel at much faster speeds. Unlike sound, however, it can’t propagate information faster than light. It takes more than five seconds for sound to move one mile.
Unlike sound, light is not a pressure wave. It’s a fundamental particle called a photon that doesn’t require a medium to travel. This means that it can travel much more quickly than sound. Wind is an example of an object traveling faster than the speed of light. It’s no different than a train racing along the tracks or a comet zipping through space. As a mechanical wave, light cannot travel faster than sound.
Is There Anything Faster Than the Speed of Light?
Einstein’s Special Relativity established a universal speed limit. A massless particle can only approach this limit, while a massive particle cannot exceed it. However, the speed of light for an object traveling at that speed must be greater than that of the object to reach the cosmic end. This is why we cannot see a moving mass in a vacuum. But it is possible for a charged particle to move faster than the blazing light.
A study conducted by Italian scientists has demonstrated that neutrinos can travel faster than light. Although other researchers are sceptical, this finding could overturn a fundamental rule of modern physics. According to this principle, nothing travels faster than the speed of light, which is 299,792,458 meters per second. In a nuclear reactor, the particle emits a blue glow, called Cherenkov radiation. This phenomenon was first measured in 1934 and was later recognized as an important discovery in physics. In 1958, a Soviet scientist named Pavel Cherenkov was awarded the Nobel Prize for his discovery.
The speed of light is the universal speed limit, and it is the basis of the universe. At faster speeds, the spatial dimension will shrink and the clock will slow. In a vacuum, space and time are fixed background conditions, while higher speeds will not affect the external observer. It is possible to go faster than light. The question is, “Can you do it?” and we will answer the question for you!
What is the Speed of Light in a Vacuum?
The speed of light in a vacuum is known as the speed of light in vacuum, commonly abbreviated as c. It is one of the fundamental physical constants in the world, being 299792458 metres per second. Despite its importance in the physical world, many questions about the nature of the universe remain unanswered. What is the speed of light in a vacuum? What is the definition of this speed?
Einstein used astronomical measurements to come up with his famous estimate of light‘s velocity. He observed that light from moving sources travels at the same speed as light from stationary sources. The resulting inverse kinetic energy equates to the velocity of light in an atmosphere. This makes it possible for the speed of light to change as the Earth moves from a near-stationary orbit to a distant one.
Since ancient times, philosophers have sought to discover how light works and the speed of light. While they have not yet discovered the precise answer, scientists have been measuring light‘s speed since the late-17th century, and have made tremendous strides in our understanding of its mechanics. While light may be the fastest thing in the Universe, it can vary depending on the relative motion of the source and the observer. Moreover, the Doppler effect can alter the frequency of light, and certain experiments are necessary to confirm this theory.
How Would Light Speed Be Possible?
If you have ever wanted to travel faster than the speed of light, then you’ve probably asked yourself that question. First, let’s look at what we mean by light speed. According to Einstein’s theory of special relativity, the speed of matter cannot exceed the speed of its constituent waves. Thus, it is physically impossible to move an object faster than this limit. It is, therefore, not possible for humans to travel faster than the speed of a moving object.
In the early modern period, there was no known way to determine if light travelled instantly or at a finite speed. The first known examination of the speed of light was conducted in ancient Greece, when the ancient Greeks debated the topic with Islamic scholars and classical European scientists. Romanus provided the first mathematical calculation of the speed of light. Then, in Einstein’s time, scientists began providing increasingly precise measurements of the speed of a moving object.
One of the most famous experiments to prove the speed of light was conducted by Danish astronomer Ole Romer. He wanted to develop a reliable timetable for sailors at sea. His experiment revealed that the eclipses of Jupiter’s moon Io from Earth often differed from the calculations he made. When the two bodies are moving away from each other, the eclipse lags behind, while it shows up ahead. And when the two are near each other, the eclipses occur on time.
Is it Possible to Travel at the Speed of Light?
While it may sound incredible, you can’t travel at the speed of light. According to Einstein’s theory of special relativity, the speed of light is the cosmic limit. This is expressed in the famous equation E=mc2. If we were able to travel faster than light, we’d be traveling at a much slower pace than we do today. This would mean that if we tried to get anywhere, it would take about 20 minutes for us to reach our destination.
The energy required to achieve this speed is a major challenge. The largest particle accelerator on Earth, the Large Hadron Collider, has recently accelerated protons close to the speed of light. However, the amount of energy required to achieve the speed of light would be inconceivable – the proton would require near-infinite energy. Therefore, there is a great deal of skepticism in the field of quantum physics.
In fact, even if you do manage to reach the outer edges of our solar system, you would be unable to stop and see the far side of it. The entire universe would be just over a billion miles across if we traveled at the speed of light. So, what is stopping us from reaching the outer limits of our solar system? It might just be a matter of time before the human race catches up.
Can the Speed of Light Change?
The question “can the speed of light change?” has long fascinated scientists and physics enthusiasts alike. In fact, it is the subject of two separate papers. The first paper proposes that light can undergo a phase shift as the universe expanded and cooled. As it reaches a certain temperature, liquid water turns to ice. The other paper argues that the speed of sound never varies. Both papers make a number of important assumptions.
A more reasonable explanation for this difference between speed and distance is that the underlying structure of space and time is what affects the speed of light. For instance, the light in a vacuum expands and contracts. This expansion of spacetime causes objects to be separated at higher speeds than the speed of light. This means that the speed of light can increase in both directions. In a vacuum, however, light travels at the same speed.
As the light in the vacuum of space increases and decreases, its speed also decreases. As the vacuum of space continues to expand, it will be possible for the speed of light to change. The previous two papers considered the possibility that the speed of light can change, but the new paper includes observations that contradict the first two. In this case, the difference between the two papers lies in the way they define the speed of light.
Understanding the Speed of Light
In order to understand the speed of light, you first have to understand how it works. It is a form of electromagnetic wave that interacts with charged particles, such as electrons. The light is then reflected by charged particles, creating electromagnetic fields. The medium changes the angle that the light travels at, affecting the speed of the light. In a vacuum, the maximum speed of light is 186,000 miles per second, or 300 million meters per second. The speed of the light in a vacuum is the upper limit of all possible local speeds. Einstein’s Principle of Relativity is the most important piece of physics, since it demands that the laws of physics are not dependent on arbitrary values.
The speed of light is a physical constant. The numerical value of c varies depending on the unit system that it is in. In the case of geometrized units, c = 1. This means that if you multiply the speed of light by one, it will remain the same. In contrast, c = 299792458 m/s in an elliptical unit system, c is equal to 1.
The speed of light in a vacuum is measured in inches per second. It is a fraction of an inch, but in imperial units, the speed is two hundred and ninety nine millimetres per second. The same speed of light is recorded for a tenth of a mile. It is the same as the average speed of light in a vacuum. There is no limit to the number of meters per second that light can travel in.
What is the Speed of Light in a Vacuum?
What is the speed of light? The answer to this question can be found in several fields of science, including physics, astronomy, and mathematics. The speed of light in a vacuum is often denoted c and is one of the most important physical constants in the world. The actual speed of light is 299792458 metres per second, but the definition is much more complex than that. Let’s look at some of the many different ways to find out how fast it is.
In classical physics, light is modeled as an electric field, and therefore its velocity is the same in a stationary source and a moving one. Thus, the speed of light from a lighthouse or a supersonic jet travels at the same rate. However, the speed of light in a stationary object is slower than the speed of light traveling through it. It is not known what factors influence the speed of an object’s speed of sound, but Einstein’s theory of relativity explains how the speed of light works.
What is the speed of light in a vacuum? The speed of light in a vacuum is 299,792,458 meters per second. The original definition of this constant was derived by Scottish physicist James Clerk Maxwell. Despite the fact that the speed of light in a vacuum is extremely difficult to measure, modern studies are calling into question what is the exact speed of the light in a vacuum.
Why Does Light Travel So Fast?
The speed of light can be considered the cosmic limit. It is measured as 1/299,792,458 m/s. The question, “Why does light travel so fast?” has been a popular one for scientists for decades. As the speed of light is constant, it’s impossible to go faster than it. So, why doesn’t mass travel faster than light? This question will be answered in this article.
The speed of light makes it impossible for a mass to stop it from travelling. This is because light waves are already at non-zero speeds. They don’t need to accelerate in order to continue their journey. This is why the speed of light is infinite. And if you’re curious, here are some of the reasons that light travels so fast. It’s possible that it’s impossible for us to see light at this speed.
A photon of light does not have to accelerate to reach light speed. In fact, it already has that speed. It only needs to be accelerated to reach that speed. An image of a laser beam is the best way to illustrate this concept. A beam of light traveling at a high speed doesn’t need to be stationary to be visible. This also allows it to penetrate obstacles without causing harm. The speed of light is the same in every direction, so the question is, “Why does it travel so fast?”
