The speed of light is the fastest observed speed in nature thus far. It is critical in Einstein's equation for the energy of matter E=mc^2, where E is energy, m is mass, and c is the speed of light. It is also important for its implications in astrophysics. Black holes allow no light to escape an area, but if one can travel faster than light, one could conceivably escape the hole. It is also speculated as possible to go back in time if one could travel faster than light, or to traverse space in a zero amount of time. Many of the implications of light speed have weight in quantum and astronomical physics and are still being investigated.

Who try to measure the speed of light?
Roemer was the first to measure the speed of light.
How would you measure the speed of light?
Light years
What happens if you are driving a car at the speed of light and you cut your headlights on?
They'll leave your car at the speed of light, and when that light passes anybody, they'll measure the speed of the light as it passes them to be the speed of light.
How do you measure the speed of light?
by getting boners.
Does a megaphone measure light and speed?
yes it does
1600s Galileo attempted to measure the speed of light using blank?
In 1600 Galileo attempted to measure the speed of light using lanterns and shutters
Who was the first to measure the precise speed of light?
The Danish astronomer Olaus Roemer was the first to measure the speed of light. (within 25 % of the actual value)
Why it harder to measure the the speed of light than it is to measure the speed of sund?
Roughly speaking, light moves about a million times faster than sound in air.
Which is faster and why speed or light?
Light is faster because speed does not move. Speed is a measure of the rate of movement but, in itself, it does not move - at all!
How long is the speed of light?
The speed of light isn't a distance so it has no length it is a measure of speed, which is roughly 186000 miles per second.
The speed of light measure?
Light travels at about 186,000 miles per second
Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
