Light Usually travels at the same speed,670million miles per hour=186000feet per second. Or if you want to be really accurate 186282 feet per second. Its speed cannot go higher than this, it can, however, co slower than this depending on what material you shine it through the slowest light has ever been recorded was just over 60kmph or around 40mph so anyone who has been down the M1 has travled faster than light!

The distance to the Andromeda Galaxy has been measured by several methods and is about 2.4 million light years When we look at the Andromeda Galaxy how long ago was the galaxy in the form that we are?
About 2.4 million light years away.
How do they time the time it takes for the light coming from the sun to reach the earth?
The distance to the Sun, and the speed of light, had been established separately, so the time was now easy to calculate.
The oldest objects in the solar system whose age has been measured are?
meteorites
If it takes 8 minutes for the light from the sun to reach earth as measured from earth and if you could ride a beam of light from the sun to the earth and time it would it take fewer minutes?
First, any object with mass (which includes you and me) cannot actually travel at the speed of light. But you can get very close, in principle. However, assuming you were moving very, very close to the speed of light, the time you experienced on board your ship would be exceedingly short. From the perspective of a photon itself, the trip time is exactly zero. The theory of Special Relativity gives us a way to calculate the trip time, and the equation includes a multiplier called the Lorentz Factor, which comes out to zero for the velocity of light. ========================================== If you and your brother are both wearing wrist watches, and you go flying past him ... the speed doesn't matter ... and as you pass him you both look at each others' watches, then you'll say that your brother's watch is running slow, and your brother will say that YOUR watch is running slow. You'll both be correct, and the faster you fly past him, the slower each of you will see the other's watch running. If it were possible for you to sail past him at the speed of light, then he would say that your watch has stopped, and you would say that HIS watch has stopped. Just as at any other speed, you would both be correct. I know it doesn't make sense, but it happens to be true. It's been observed thousands of times over the past hundred years or so. And a correction for it is built into the GPS system, to correct the clocks for the speed of the satellites. Otherwise GPS would give flaky and wrong results.
What is speed x5 faster than light?
According to accepted physics theories, nothing can go _AT_ the speed of light.It may be - it is probable! - that our "accepted physics theories" are incorrect in at least certain restricted cases. No one would be happier than I to learn that it were possible to go faster than light. But to the limits of our observational techniques, the theories have matched the realities of the experiments, and no way around them have been found - yet.However, until a few fundamental physical laws are overturned, there really isn't any point in discussing what "speed 5x faster than light" might look like.
What is the speed of gravit?
It's never been measured, but it is assumed to be the same as the speed of light.
What is the speed of gravitional force?
It's never been measured, but it is assumed to be the same as the speed of light.
Why does light have a defined speed?
Because it takes light time to move from one place to another. The time it takes to move a measured distance has been measured, and its speed has been found to be a certain number. A contest was held to name that number, and the winning entry was "The Speed of Light".
How do you know how fast light travels?
Its speed has been measured accurately, using lasers.
How do know how fast light travels?

What speed was the slowest Tornado?
There is no single slowest tornado as many tornadoes have been completely stationary and just stayed on one spot.
The speed of light has been measured to be about?
The speed of light cannot be measured IN A WAY. However it travels at 1,079,252,848.8 miles per hour or 299,792,458 meters per second. It cannot be measured however the numbers I showed is one way. Light cannot have a specified measurement, unless the light source is big or small etc...
What is the speed of light per planet?
The speed of light is the same for every observer everywhere. That is a fundamental tenet of the theory of special relativity (and everything based on it, such as the general theory of relativity and quantum field theory). To date no violation of the consistency of the speed of light has been measured. By the way, this does not say the speed of light is the maximum speed, just that the speed of light is constant, so the possible discovery of faster-than-light neutrinos does not invalidate this.
What speed does semen ejaculate?
The average speed of ejaculation has been measured to be approximately 28mph.
If a plane is traveling at the speed of light and turns on its head ligths will the light be even with the plane?
A plane CAN'T travel at the speed of light.If a hypothetical super-spacecraft goes very close to the speed of light, and a beam of light is emitted from the spacecraft in the "forward" direction, the speed of the beam of light from the spacecraft would be measured to be the so-called "speed of light", i.e., 300 million meters per second. Note that the speed of this beam of light, as measured from Earth, would ALSO be 300 million meters per second. This seems weird, or even impossible, but it has been confirmed by the famous Michelson-Morley experiment, and explained by the Special Theory of Relativity.
Do neutrinos travel at the speed of light?
No, neutrinos have been shown to have a small non-zero mass. They can't get to c (the speed of light in a vacuum). The only thing a supernova can eject at the speed of light is photons. Update: Recently an experiment has measured neutrinos traveling above the speed of light. An explanation is yet to be offered.
How did Albert Enistien hipothesize the speed of light?
He didn't. It was James Clerk Maxwell, several years before Einstein started doing any significant work. The speed of light was predicted before it was ever measured with any accuracy. By the time Einstein came along, it had been measured accurately enough to confirm Maxwell's prediction. That in turn was the proof that light is an electromagnetic wave.
