Is Time Travel POSSIBLE?

Ever wonder of travelling through time? Could it be possible in reality?

I believe you definitely had watched "Back to the Future Film".

Even if it is possible, I would always wonder, this issue will definitely concern human right, perhaps the same issue concerning human clone. Ok, let’s say you failed in your exam, you go back to the past and re-sit for that paper. Ha, definitely you had memorized all the perfect answers. Eventually, you pass with flying colors. That’s dirty.

For me, there are pros and cons. One of the pro is that, if u murdered someone, you can undo it. Isn’t it great? Haha.. just my silly theory of it.

Now let me show you the real answer for it (picked from “The Life Explorer Magazine”)



Possible or Not?

This is the question everyone would love to answer. Time travel has been a favorite theme of science fiction novels. And some of it is actual fact. For example, it has been proven possible to travel forwards in time. Einstein’s theory of relativity predicts that an observer moving relative to Earth can leap into Earth’s future, and the effect has been confirmed using atomic clocks.

Going back in time is not as easy. Relativity does not rule out the possibility of travelling back in time, but all the scenarios so far require very exclusive circumstances. One way to go back in time is to use a wormhole in space. Theorists speculate that such a tunnel – or star gate – lining two points in space-time, really might exist. If this is true, then one could be adapted to form a time machine. You could go through it and exit not only somewhere else, but “somewhen” else too. And that could be the future or the past.


Issues arise if it is possible

If this were possible, then all sorts of problems and paradoxes could arise, namely, is it possible to alter the past or affect the future? It certainly seems too irrational for some physicists. Stephen Hawking suggested a “chronology protection conjecture”, surmising that something would intervene to prevent physical objects or influences looping back in time. For example, quantum vacuum energy might surge without limit near the entrance to the wormhole, blocking it.

Hawking also noted that it is hard to get funding for time travel research. So it is likely that this issue will have to wait a long while to be proved or disproved.
