GENERAL THEORY OF RELATIVITY--2
After published Special theory of relativity which is valid only for inertial frame of reference its mean special theory of relativity can be applied when any object travelling with a uniform velocity there is no acceleration in its motion but that thing does not exist in real world.
In our universe things do accelerate.Einstein want to know there are any relation between gravity and acceleration.After few observation Einstein found acceleration and gravity both are not different thing but how let discuss it with a example
Suppose you and your friend are in a elevator.Elevator is going to upward with a uniform acceleration of 9.8m/s^2
then it is very hard to determine what is your position to being in elevator because your elevator accelerate 9.8m/s^2 per second and 9.8m/s^2 is the gravity at earth.
Without time we can not find our position in this universe for example-
Suppose your girlfriend fixed a meeting with you she told you she wold meet you in a five star motel then she will have to tell name of motel where she is going to meet you and time what time would you meet.
Suppose she told you only place name where you would meet her but she did not mention what time she will come at that palace.then this meeting would be possible?
Not that not possible to meet someone without fix the time meeting.
Now let think about another aspect your girlfriend told you she will meet you at 4 pm but where she did not mention any place name in this situation your meeting could not be possible because that is not completed data to fix the meeting with someone.So as far we know well time is directly connected your universe.

then it is very hard to determine what is your position to being in elevator because your elevator accelerate 9.8m/s^2 per second and 9.8m/s^2 is the gravity at earth.
This is the reason you can not determine your accurate position if you are in a elevator which is accelerating 9.8m/s^2 per second. Same thing happen when any object falling toward the earth under a free fall it accelerate 9.8m/s^2 while there is no external force applied on it.
it accelerate under the Gravitation force of earth this acceleration is the same as the gravity at the surface of earth
Then Einstein found that gravity and acceleration both are not different
In general theory of relativity Einstein explain that time are not isolated in this universe.
Suppose your girlfriend fixed a meeting with you she told you she wold meet you in a five star motel then she will have to tell name of motel where she is going to meet you and time what time would you meet.
