Web2 Answers. 1) It is impossible for matter to go at the speed of light, as it takes an amount of energy equal to m c 2 ( 1 1 − ( v c) 2 − 1) to accelerate it to a speed v, and this energy becomes infinite as v → c. In another sense, reference frames moving at the speed of light (or faster) are excluded from Einstein's principle of equivalence.

WebA light year is a measurement of distance. This distance is measured by how far light can travel in a year. Light travels at approximately 186,000 miles per second. Example: How far does light travel in 3 months. 3 months is 1/4 year. So enter .25 in the calculator to determine the distance that light travels in 3 months. Answer ... More than 100 years ago, a famous scientist named Albert Einstein came up with an idea about how time works. He called it relativity. This theory says that time and space are linked together.
