You can see the speed of light right now. Here's one way:
We know precisely and exactly when any moon of Jupiter should blink out as it
passes behind the planet. If we set our clock when Jupiter is near us, and then
watch the moons when Jupiter is on the other side of its orbit from us, we see
the moons blink out 30 or 40 minutes later than they should. That's the extra
time it takes the light from there to go the extra distace to reach us.

How do you understand the speed of light in human terms?
The speed of light is so incredibly fast that it is difficult to express it in human terms. But here are some comparisons. If you could run at the speed of light, you would be able to run around the world seven times in a single second. If you could run at the speed of light, you could run from one time zone to another in the blink of an eye. You would be able to see ten sunsets in the same evening! When you are talking on an international phone call, you can say something on the phone. Your call will go up into space to a communications satellite 23,000 miles into space, and back down. And you hardly notice the delay!
How does these two quantities determine the speed of light?
The speed of light is determined by two fundamental physical constants: the permittivity of free space and the permeability of free space. These constants are intrinsic properties of the vacuum and dictate how fast electromagnetic waves, such as light, can propagate through space. The speed of light is given by the equation c = 1/√(ε₀μ₀), where c is the speed of light, ε₀ is the permittivity of free space, and μ₀ is the permeability of free space.
Is it possible to travel at the speed of light in water?
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
How could human thought travel 24 billion miles per second?
Human thought does not travel at a physical speed like light or sound. It is a neurological process that occurs within the brain at a much slower pace. Communication can travel at the speed of light through technologies like fiber optics, but human thought is a complex internal process that does not have a measurable speed in terms of distance covered per second.
What would it take to make a spacecraft travel at the speed of light?
A new form of manipulating space. It is impossible at our current level of technology. Currently, it would take an infinite amount of fuel to make a spacecraft reach the speed of light, then a continuous flow of an infinite amount of fuel to sustain light speed. This makes it impossible. As an object increases speed, its apparent mass in this space-time increases. As it approaches the speed of light, its mass approaches infinite. As its mass approaches infinite, an infinite amount of fuel is needed to propel it faster. Even if we could achieve light speed, it would still be impractical as a interstellar speed limit. It would be okay for tooling around the solar system, a day or two trip to Neptune. The nearest star is four light years away, so it would take four years to reach that solar system at the speed of light. When we got there, we are in no position to exploit that system, so the reasons for traveling there diminish. If we could, somehow, manipulate space so as to achieve faster than light travel, then interstellar exploration becomes an option. There is nothing that limits space to the speed of light, so if we could create a stretched patch of space in front of our vehicle and a compressed patch of space behind it, we may be able to ride a wave, if you will. In the local patch we are setting, we aren't moving, but the patch we're on is drifting down hill so to speak. Speculation is all.

What is the trem for the relationship between the speed of light and the measurements of time and space?
Time and space are related by the speed of light space r=ct where t is time and c is the speed of light.
Which is a comparison of the speed of light in a material compared to the speed of light in empty space?
The speed of light in any material medium is less than it is in empty space.
The speed of light is what in space?
The speed of light in a vacuum (space) is about 3x10^8 m/s. The most accurate measurement is:
How does one travel faster than the speed of light?
No human or machine can travel the light of speed. No matter how close you are to the speed of light if you have all the thrust in the universe you cannot get going past the speed of light. The familiar notions of absolute space and absolute time independent of your relative motion must give way.
What is the thing that moves by constant speed in space?
An object moving by constant speed in space could be a spacecraft, satellite, or a celestial body like a planet or asteroid. In space, objects can maintain a constant speed due to the absence of friction or air resistance.

What tool for measuring the space?
light speed:)
Is the speed of light in space varies with wavelength?
No, it does not.
At what speed does an RF signal travel in space and how does it compare to the speed of light?
An RF signal travels at the speed of light in space, which is approximately 299,792 kilometers per second. This means that RF signals travel at the same speed as light in a vacuum.
At what speed do light waves in space travel?
Light waves in space travel at about 186,282 miles per second or approximately 300,000 kilometers per second. This speed is constant and is known as the speed of light in a vacuum.
What form of energy can travel through space at the speed of light?
(a) Electromagnetic waves; that includes light. (b) Gravity waves.
