The speed of light is around 86,000,000 miles per second and there is not anything that can attain nor exeed that speed. It has been sugested that the power of thought may reach such a speed but has never been proven.
It is not. Nothing that we are aware of moves faster than light.
Yes, the Big Bang was faster than light. During the initial expansion of the universe, the rate of expansion was faster than the speed of light.
The universe is expanding at a faster rate than the speed of light.
In fact, distant parts of the Universe are moving away from us faster than the speed of light.
Nothing can travel faster than the speed of light in a vacuum, according to the theory of relativity.
The speed of light (ca. 300,000 km/second) seems to be the speed limit in the Universe. Nothing is known to travel faster than light; it seems likely that travelling faster than light is not possible.
No, never! it is disproved by Einstein
Then our Universe would be quite different than it is.
No, an echo is not faster than light. Light travels at the fastest speed possible in the universe, which is approximately 299,792 kilometers per second in a vacuum. Sound, including echoes, travels much slower than light, at about 343 meters per second in air.
light is faster than sound simply because it is. With the possible exception of neutrinos, light is the fastest thing in the universe. There are, however, supersonic jets in use by the military.
Light travels faster than sound in the universe. The speed of light in a vacuum is about 299,792 kilometers per second, whereas the speed of sound is significantly slower at about 343 meters per second in air.
