Why is faster than light travel impossible?
Nothing can move faster than the speed of light. When Einstein set forth his theory of relativity, this was his inviolable postulate: that there was an ultimate cosmic speed limit, and that only massless particles could ever attain it. All massive particles could only approach it, but would never reach it.
What is the evidence that light is a wave?
In 1801 a physicist in England, Thomas Young, performed an experiment that showed that light behaves as a wave. He passed a beam of light through two thin, parallel slits. The bright and dark bands demonstrated that the slits were causing light waves to interfere with each other.
Why does light go so fast?
Ergo, light is made of electromagnetic waves and it travels at that speed, because that is exactly how quickly waves of electricity and magnetism travel through space.১৬ জুলাই, ২০২০
