can anyone explain the theory of relativity for me ??

Answer 1

If I am travelling at 10mph north, my relative is called uncle john.

Answer 2

Einstein actually had two theories of relativity, Special relativity and general relativity. The one you have probably heard of is general relativity.

Basically general relativity explains how gravity works on large objects such as planets and asteriods. Again, trying to keep things simple, Einstein theorized that the fabric of space, known as spacetime works kind of like a trampoline in that when mass is put on it, it will bend. Then bending is known as warping.

Einsteins theory of special relativity explains how time and distance are all relative. While it is hard to understand why, the theory is that how fast you are moving determines how slow things time runs for you; the faster you are moving the slower time runs for you. And this works no matter how fast you are moving, but its affects are so minimal that unless you are going super fast you are dont notice it. The same applies to distance. The faster you are going the smaller things appear. There is a lot more to it then that but basically that is what it says.

Answer 3

Relativity is a physical theory, introduced by Albert Einstein, that discards the concept of absolute motion and instead treats only relative motion between two systems or frames of reference. One consequence of the theory is that space and time are no longer viewed as separate, independent entities but rather are seen to form a four-dimensional continuum called space-time. Full comprehension of the mathematical formulation of the theory can be attained only through a study of certain branches of mathematics, e.g., tensor calculus. Both the special and general theories have been established and accepted into the structure of physics. Einstein also sought unsuccessfully for many years to incorporate the theory into a unified field theory valid also for subatomic and electromagnetic phenomena.

Answer 4

General or special? Ok.. if your asking this question you either have no knowledge or hope that there is an easy way to understand it all. Start with the Special Theory. Also... there is no such thing as gravity. Time is not a unit by itself (spacetime) and it is not a constant (ie. one second is not one second relative to everything else). Nothing with mass can reach the speed of light and nothing can travel faster than the speed of light. Well, that's a small start.

Answer 5

Best example is the fly on the plane.
A fly is flying from the back of the plane to the front of the plane. Relative to the person in the back row the fly is moving at 5mph. Now there is a super person on the ground who has x-ray vision and can see the fly in the plane from the ground. Now since the plane is travelling at 500mph, the fly relative to the person on the ground is travelling at 505mph. Does this make sense?

Answer 6

Relativity is quite simple in some sense of the terms. Special relativity is based on the Michelson- Morley experiment of ~1890 that showed that the speed of light will be measured by any observer as the same (i.e. "c") regardless of the speed of the observer. This is kind of crazy, since if you are on a train going 30 MPH and you are passed by a train going 60MPH then you will measure the speed of the faster train as 30MPH (relative to you). NOT SO with measuring the speed of light. So if you do all of the math that is a consequence of this, then it turns out that nothing can travel at the speed of light, and as you try to get close to the speed of light, your mass goes to infinity and your time drags down to zero and your length diminishes to zero. It sounds crazy but it has been proven over and over again with every experiment in the book so we just have to accept it as reality.
The general theory of relativity is based on the observation that if you are on an elevator at rest sitting on the surface of the Earth and you let a ball drop from your hand, it will fall to the ground. If you are still in that elevator and this time you are out in empty space and that elevator is accellerating at 9.8 meters per second per second, and you let your ball fall from your hand, you will see it drop to the ground in the same manner. Therefore accelleration and gravity are the same, and therefore E=mc2, i.e. matter and energy are equivalent and space is warped by the presence of mass in the vecinity. Once again it seems crazy but it has been proven over and over again by every experiment in the book so we just have to accept it as reality.

Answer 7

In our daily lives, we live under Newtonian rules, when we walk, run, play tennis, drive a car, ride an airliner.
Relativistic effects are another set of rules, for the Really Weird S@@@ That Happens at very close to the speed of light. Since we don't spend any time in that neighbourhood, don't sweat about the details. It matters as much to you as the New Dehli bus schedule, when neither you or anyone you know lives there.

Answer 8

In physics E=mc2 is an important and well-known equation, which states an equivalence between energy (E) and relativistic mass (m), in direct proportion to the square of the speed of light in a vacuum (c2).

The equation was first published (in a slightly different formulation) in 1905 by Albert Einstein, in what are known as his Annus Mirabilis ("Wonderful Year") Papers. In these, he showed that a unified four-dimensional model of space and time ("spacetime") could accurately describe observable phenomena in a way that was consistent with Galileo's Principle of Relativity, but also accounted for the constant speed of light. His special theory of relativity ultimately showed that the traditional (Euclidean-Galilean) assumption of absolute time and distance was incorrect, and, as a consequence, that mass and energy are different only in form.

Thus c² is the conversion factor required to formally convert from units of mass to units of energy, i.e. the energy per unit mass. In unit-specific terms, E (joules) = m (kilograms) multiplied by (299792458 m/s)2.

There was a young lady called Bright
Who could travel faster than light
She left one day
In a relative way
And came back the previous night

Answer 11

Einsteins theory of relativity isoften thought of as e=mcsquared.

e stands for the amount of energy youwould get if you multiplied the mass of an object times the velocity of light multiplied by itself. If you had a pound of uranium, and pultiplied it by 180,000 titimes 180,000 (the speed of light) that would be the amount of energy you would derive. (A fantastically large amount!)
