What is absolute in relativity?
“Absolute relativity Theory of Everything” proposes the idea that the universe is actually comprised of 4 spatial dimensions. The expression for this is AR= Ut, x, y, z = 0. Where Ut is the continuous production of New Space second for second.
What is difference between GTR and STR?
The basic postulate of STR is that light travels in vacuum with the same speed c irrespective of frame of reference. This gives rise to many consequences like time not being same for two observers, non simultaneity of events and so on. GTR deals with gravity. Einstein proposed that space-time is curved(non euclidean).
What is general relativity in simple terms?
What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.
What is the difference between Newtonian physics and general relativity?
In Newtonian mechanics, quantities such as speed and distance may be transformed from one frame of reference to another, provided that the frames are in uniform motion (i.e. not accelerating). In special relativity, there is a natural upper limit to velocity, the speed of light.
What is time dilation in special relativity?
time dilation, in the theory of special relativity, the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock.
What is general about the general theory of relativity?
Einstein’s field equations In general relativity, the world line of a particle free from all external, non-gravitational force is a particular type of geodesic in curved spacetime. In other words, a freely moving or falling particle always moves along a geodesic. .
What is the difference between general theory of relativity and relativity?
In brief, general theory of relativity is made of a more advanced and generalized version of the special theory of relativity. The key difference between general relativity and special relativity is that general theory of relativity deals with space-time continuum whereas Special relativity only deals with the inertial frames.

What is special relativity?
Special relativity, or more precisely, special theory of relativity was proposed by Albert Einstein is 1905. The accepted dynamics at that time were the Newtonian mechanics. The special theory of relativity explained some of the observations that scientists couldn’t explain using classical mechanics.
Why is general relativity better than Galilean relativity?
The theory of general relativity better enables us to study distant stars. Let’s heap a second scoop onto the relativity cone — a lovely taste of Black Forest courtesy of German-born physicist Albert Einstein. As we just mentioned, Galilean relativity, even after it got a few tweaks from Newtonian physics, was broken.
When did Einstein propose the special theory of relativity?
Albert Einstein proposed the special theory of relativity in 1905. Later, he proposed the general theory of relativity in 1916. These two theories became the foundation stones for modern physics. The theory of relativity describes the behaviour of matter when its velocity reaches the speed of light.
