There is so much wrong with just the way that this question is asked....

Einstein developed a Theory that includes time as the 4th dimension.
If you think about life and motion in 3 dimensions a 4th can exist because, for example you have a meeting to go to in a building at 4th street and 5th street on the 4th floor at 4 pm. Each coordinate here represents a relative place within space. 4th street is your x coordinate, 5th street is your y coordinate, 4th floor is your z
coordinate, and 4pm is your time in relation to all others.
where the speed of light enters into this is the following. Einstein determined that the fastest that any body can travel is the speed of light, as something diverts more of its vectoral motion towards a specific direction, less is attributed to the others. It is easier to think about this as an equation where the sum of the 4 dimensions equals the speed of light. i.e. x+y+z+t(time)=c (the speed of light)
so since c is a constant, and unchangeable. as someone travels faster in the x or as x increases the remaining y, z, and t variables must decrease. In other words, the closer you get to the speed of light, you will appear to be moving through time at a much slower rate than those around you. Conversely to you others will appear to be moving slowly while you are traveling at a normal speed.

A test was conducted in the late 60's to confirm this theory, two planes with state of the art atomic watches that could tell exceedingly precise time traveled around the world. At the same time two synchronized watches that were exactly the same were left on the earth. When the planes landed the watches were compared and showed that there were differences between them: the time on the watches on the planes was a few milliseconds behind those that were left on the ground.


This is a very very very brief explanation of one of the components of the theory of general relativity.

for more information you can read the first few chapters of the following books.

time slows down in a moving vehicle. think of a light clock, it has 2 mirrors,1 at the top and 1 at the bottom, with a beam of light bouncing between them, and every time the light bounces the clock ticks. now imagine that you can go at amazing speeds so light seems quite slow. when you are standing still the light travels in a straight line vertically so it takes n seconds to get there. but when you run the light has to travel diagonally to get to the same point, and the light cant speed up so it has to take longer between ticks, therefore time must slow. but it only shows to the people outside, to the people inside it would seem that time outside was slowing down.

I guess you mean Albert Einstein ... :-)

The special theory of relativity was proposed in 1905 by Albert Einstein in his article "On the Electrodynamics of Moving Bodies."

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915.

He was awarded the 1921 Nobel Prize for Physics for his explanation of the photoelectric effect in 1905 (his "wonderful year") and "for his services to Theoretical Physics."

He made significant contributions to quantum mechanics, statistical mechanics, and cosmology.

E=mc2

I think it means that an object's energy is equal to its mass times the speed of light squared.

Exactly how language might influence thought is yet unclear. However, space and time respect of light is still unclear what your language is influencing.

First spell "Einstein." You don't deserve to know!!!
