What does Einstein explain in his theory of relativity?

Question

I need a clear explanation.

Answer 1

There are three main relativistic theories presented by Einstein. The Theories of Special Relativity, General Relativity and his Principle of Relativity. The general principle of relativity states that physical laws should be the same in all reference frames; inertial or non-inertial. Galileo's principle of relativity which states: that all uniform motion was relative, and that there was no absolute and well-defined state of rest. This combined with the fact that the speed of light is constant for viewers in all frames of references forms the basis of Special Relativity. General relativity is Einstein's theory that gravity is a property of space-time curvature. Hope that's short and sweet enough for you. Yours truly,

Answer 2

There are Special Relativity and General Relativity, for the Special Relativity, it is about a Space-Time relations between two different frames of reference, in more simple words, how to correlate a space and time calculations in a frame to that of another frame, based on the fact that the speed of the Light is the same in all inertial frame of reference and that the laws of the nature is independent on the state of motion of a frame relative to another. The Special theory led to many surprising results, such as time dilation, energy equivalence to mass,.....
For the General Relativity it is about Gravity, that the Gravity is a change in the space-time or gravity bend the space-time inside its effective region, rather than a force exerted between massive bodies. well .... there is link you can use to download Enistein's book explaining his own theory www.marxists.org/reference/archive/einstein/works/1910s/relative/relativity.pdf

Answer 3

Theory of relativity refers to two of Einstein's theories: Special and General Relativity.

Answer 4

Einstein had two theories of relativity. His Special theory of relativity explained that the speed of light is constant, regardless of the speed of the observer.

Simply put, if you are driving down the highway at 50 mph with your headlights on, the speed of light coming from your headlights will always be 186,000 miles per second, and not 186,000 miles per second plus 50 mph. The speed of light is constant, regardless of the speed of the observer.

The general theory of relativity says that objects with mass bend space-time, and therefore are able to bend light. This effect has been observed when nearby galaxies have bent light from galaxies much further behind them.

Answer 5

He says that the speed of light in vacuum is absolute and hence all other physical quantities are relative.

All other formulae and theories are based on this fundamental principle.

Speed of light is absolute, because while we are not moving or while we are moving toward a beam of light or while we are moving away from it, we will get the same value for the speed of light in vacuum.

If speed of light were not absolute, then it must be relative. In that case the speed should be greater when moving toward a beam and should be slower when moving away from it and maximum when at rest.

This is not happening. Hence the speed of light is absolute.

To measure the speed of light as one and the same, the meter scale in a moving laboratory must decrease in its length and the time should move slowly.

Thus all quantities are changing their values with respect to the speed of the laboratory in which they are. That is all other quantities are relative; they are not absolute.

However, the relation between these quantities, i.e., the laws of Physics will be the same in all such moving laboratories.

Answer 6

Einstien came out with special relativity first which explained behavior at or near the speed of light. He later followed up with General Relativity which addressed how gravity affects space-time.

Answer 7

i will give one statement by einstein itself telling about relativity you can guess real principle from that

Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. THAT'S relativity.

-Albert Einstein

Answer 8

Marrying a relative is worse than being pushed around by a larger force.

Answer 9

I'm pretty sure it's the amount of energy you'd have if you could convert matter into energy.

"It yields the equivalence of matter and energy, as expressed in the famous equation E=mc2, where c is the speed of light."

Answer 10

all it says is...that light trvels at a constant speed no matter what.
