Please correct me if I'm wrong, according to Einstein a body that travels faster than the other the tme will be relatively slow compare to the other. It has been proven already. I've watched Professor Brian Green in you tube about the illusion of time according to him time is like a series of snap shot and every moment in the past still exists and the future is already exists.

ThanKS sir. I'm a little confuse many physicists believe we can travel back in tme and travel to future.If it is true then our future is already exist and our past still exist that we can even see it if we are able to create time machine.

If the law of physics allow us to travel back in time and meet the people thousands of years ago, are we some kind of computer program?

it makes sense Sounds interesting sir, could you give us an idea on how you are going to manipulate the time. Is it by travelling at speed of light, a very high gravity or by bending the space?

I've been very curious about this since I starting to believe about the origin of universe. What causes the big bang anyway when there was nothing in existence prior to it?

@Delbert sir I've been hearing a lot of this big bang theory I thought it was only applicable to our solar system but you were talking about the universe .if anything is non of existence even space and time then what causes the big bang and where did that huge energy come from?

@ajb do exotic matters exist if yes where can we possibly find them?

Mr. Nato they say that astronauts are fraction of a second younger when they come back to earth from space and satellites from space need to adust the clock everytime so the satellites will function properly. How do we explain these? Mr. Myuncle that means everyone inside the ship will become literally slow? The biological aging even the brain's response is delayed? It's very hard to imagine it that way.

Sir let me just clarify my understanding on what you have said, the age of the individuals inside the ship will be the same relative to the earth's time? If the ship travelled and came back 80 years relative to earth's time those crews biological age will be 80 years older ?thanks

Thnks a lot anyway . I hope ajb will give me another one

That means the biological aging of the individuals inside the ship will become slower relative to their time? How come?

I apologize if I am a little obsess on time travelling , so my understanding is anyone that can travel at great speed the time tickling would be slower from the observer , please correct if I'm wrong.How about the aging process of the crews inside the ship travelling nearly at speed of light would they be look like a lot younger than those people on earth? If yes how come the time dilation due to speed and gravitational force affect our aging process?

If I have a space ship that can travel at speed of light or nearly and I went to a planet 10 light years away and come back to earth so I would probably arrive thousands of years in the future?

Thanks a lot @ajb

Thanks @ajb . I find time machine is not really possible in nature but most physicists believe that time machine is possible through worm hole or rotating space. How can a black hole create worm hole ?Is it possible to have rotating space?
