    I have a doubt according to the theory of time travel , we can travel through time but when on travel through time, we will travel through time on the whole universe or we will travel through time on a specific space alone?

    We are already traveling through time, whether we like it or not.

    I am not sure I understand what you are asking about.

    There is no "theory of time travel".

    we can travel through time
    Only in the normal way: into the future at a rate of 1 second per second.

    but when on travel through time, we will travel through time on the whole universe or we will travel through time on a specific space alone?
    It depends on which science book you're reading.

    what source do you have ? time 'bending' is nothing i have ever heard. there is 'time dilation' from relativity theory but no 'time bending' ?????

    MY MASTER ALBERT EINSTEIN TOLD ABOUT THAT TIME AND SPACE BEND LIKE A BALL HITTING THE LEATHER SHEET .....

    REFER THIS Einstein was right: space and time bend | Science | The Observer

    yes. the warpage of space-time. that headline is a bit misleading i think.

    I JUST REFER THAT .... BUT IN THE BOOK PRODIGY I STUDIED THAT HE TOLD IT WILL BEND ....

    I know the are numerous questions on that ..... but i just want to clear mine....

    That's a newspaper, not a scientific paper.
    Ergo it should be treated with some scepticism.
    The article does eventually manage to get it right: so planets and stars warp space-time.
    Space-time isn't "space and time" and especially not "space OR time".

    what you finally want to tell ?
    if there is a change in time then there will be change in space also?
    is that you want to explain or not?

    I presume you are referring to the theory of "General Relativity". According to this, gravity is a manifestation of the geometry of space-time, more specifically it is a direct result of curvature induced by the presence of sources of energy-momentum. As such you are correct in saying that both time and space can "bend" - curvature in time gives us gravitational time dilation ( which manifests as what we observe as everyday gravity ), whereas curvature in space gives us tidal forces.

    As for the title of this thread - there is currently no credible mechanism that would allow time travel for macroscopic objects. General Relativity incorporates unusual topological constructs such as "closed time-like curves", Einstein-Rosen bridges, Krasnikov tubes and such like; however, we must remember that Einstein's models are purely classical in nature and do not account for any quantum effects. A strong case can be made that once quantum effects are taken into consideration, most of these constructs will turn out to be either unphysical, or quite simply of no practical use ( e.g. because they are always hidden behind event horizons ).
