# Can someone tell me a simplified version of Albert Einstein’s theory of relativity?

Fan of Albert Einstein’s, wondered if anyone could explain to me the theory of relativity?

Yes. It states that if you travel near to the speed of light there will occur three things

Time Expansion
Energy Variation

Special relativity – there is nothing at aboslute rest. The laws of physics are the same for all observers in constant motion (constant speed) therefore the speed of light is constant regardless of the relative motion of the person making the measurement. This leads to lack of simultaneity between moving observers – they will not agree on which events occur simultaneously. First geomteric view of space and time. Space and time are a four dimensional construct – space-time. But this space-time is “flat” – it is pseudo-Euclidean (Minkoskian really) in its geometry. General relativity – the laws of physics must… Read more »

The Special Theory of Relativity was published in 1905 and deals with (frames of reference) objects separating with constant high velocities (close to the speed of light). In this first theory, Einstein stated that the speed of light was the absolute limit for all velocities and furthermore all observers, what ever their motion, must measure the speed of light to be exactly the same. Finally, only mass-less objects may attain the speed of light. However, massive objects contract in their direction of motion, their clocks slow down relative to observer’s clocks and they gain mass and thus inertia as they… Read more »

General Relativity can be put simply with a scenario: if you are in an elevator and feel a force push you down, there is no way of tell whether that force is gravity pulling you down or if you are in space and the elevator is moving in your upward direction pushing you up.

Space and Time are enmeshed as one spacetime continuum. The addition of your motion through time and motion through space is equal to the speed of light. Therefore if you move faster through one, you must decrease motion through the other. Mass is simply “condensed” energy(E=mc^2). Gravity is curving of the spacetime continuum caused by mass and energy. Accelerated motion causes you to view spacetime in a curved manner equivalent to gravitational fields.

The perception and measurement of distant objects, especially those moving very quickly (near speed of light quickly) will be skewed by that object’s motion as well as our own motion; the object will appear shorter or longer than it actually is depending on how both us and it are moving. The reality doesn’t really change, just our perception and measurement of it.

Theory of Relativity – The Basics The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion. This does not have a major impact on a person’s day to day life since we travel at speeds much slower than light speed. For objects traveling near light speed,… Read more »

The speed of light is the same no matter how fast you are going.

probably.
