What is Einstein's Theory of General Relativity?

Question

Through a discussion of movement distortion epochs the spacetime geometry surrounding massive objects can be visualized in the concept general relativity. These temporal distortions balanced the curvature caused by mass agencies. Space geometry was modified present even in the absence of all appropriate mass objects. Einstein once said: “It should be possible to see both motion and the force of the mass." His theory with strong interaction and background geometry is useful what the stars used to be, does not dwell in it creating fictive forces, wave mapping through deformation spaces.

Answer 1

The general theory of relativity, developed by Einstein, is a landmark in the history of mankind’s view of nature. It does not support the view of gravity as a direct pulling force on bodies, rather contends that it is the consequence of deformation of three-dimensional space that objects of mass develop. This explains why all objects in a gravitational field fall at the same speed which has tremondous impact on the way we look forward to movements of astronomical bodies and internal structure of the universe. Referred to in its full name the special and general theory of relativity, this is the very cornerstone of cosmological science today, correcting generations and countless layers of theories and creating a framework of order.

Comments

I Would like to rectify something, when Brian Cox is explaining Einstein's General Relativity he states the idea that Einstein thought that the ground was the one that's accelerating upwards, That's right if he would have mentioned from the Apple's perspective, since it is the Apple that's accelerating towards earth due to curves on spacetime by the Earth. So from a falling object perspective is the earth that's accelerating upwards. I just thought that would confuse non-physicists.

Matter tells space how to curve, space tells matter how to move. Which starts first? To me it still doesn’t explain the mechanism HOW.

Im sorry but what mr cox said makes no sense and is in fact wrong. When you drop a feather and a hammer the "earth" does not accelerate "up" to hit them. Nor does newtons head "headbutt" the apple. Things fall because they are following spacetime curvature until something gets in the way. Period. End of story.

Cox's explanation/claim that Einstein's theory says the Newton's head rose up and hit the apple is ludicrous. If that were the case, why didn't Newton's head hit branches and leaves. That is not what happened. If you stand under an apple tree for a full season, eventually an apple will hit you in the head, but the branches won't come tumbling down and your head won't rise up and hit branches. That explanation is ludicrous and easily proven false by demonstration and observation. Poor!

Wait a minute, Newton's gravitational theory says everything is attracted to everything. The apple, the man, the earth are all moving towards each other. I agree he didn't know the cause. I'm unconvinced of Einstein's space/time fabric theory, to me it's aether that is the fabric of the universe and is that is being curved. Einstein himself couldn't let go of the idea of an aether.

But the earth isn't moving in a straight line around the sun......unless the sun itself warps space/time into a circle....which should only be possible with a blackholes?
Here......take a sheet of LONG PAPER.  Draw a straight line on it from one end to the other.  Then place something on top of the paper.  I can easily see a HALF circle being made, and hence, half of an orbit.  But then, the earth would have to make a drastic 180 degree turn to go around the other side of the sun.  So, the earth does NOT move in a straight line.  And that is the best case.

Well First of all we have to be careful with that apple idea because the gravity of the apple does pull Newtons head, but Newtons head has greater mass and pulls the apple and the stronger gravitational field of the Earth is stronger than both Newton and his apple so Earth's gravity wave particles dominate or pull down the apple.   Next.  The weak equivalence principle was discovered by Galileo first" the acceleration of free fall is the same for all bodies.  Don't forget about the strong equivalence principle of general relativity is that inertial and gravitational forces are equivalent, Einstein's idea

My brother asked me an interesting question the other day. Having very little background in science, his intuition is that how is it possible for "nothing" as in "space" to bend? I mean it's a valid question. If space is bendable, it is something, so what is it? What is the physical property of space?
