Do you think time travel is impossible or just really really hard?

Disregard any paradoxes like there are no time travelers in our time so it can't ever be invented or if you go back you change history for everyone or you go back before you went in the first place bla bla bla.


Just think a little creatively, do you think it would be possible to successfully time travel? Or is it something that can never be achieved?

I think it’s just really, really hard. Although we technically won’t be going back in time, but a different dimension if we’re talking about the present still being there.

You’d have to get the molecule structure of the body right/make sure nothing goes wrong and depending on what you think, it might not be you. It might be a different version of you in a different dimension because the structure of the body has to replace its self in that period of time. There is one way that you probably know of which is speed of light and going to space, but that’s nearly impossible lol. But we’re always time traveling to the future 👍👍

Actually, not only is it possible, but it’s already been done, albeit not in the conventional, Hollywood style.

Time is inseparable from space, which is why Stephen hawking used the term spacetime. General relativity decisively proves that time dilation exists, and is dependant on your speed.

To simplify a highly complex field of physics : the faster you go, the slower time becomes relative to you.

So, let’s say you hopped onto a rocket ship travelling with prodigious speed, whilst a friend of yours stayed back on Earth. Now you hurtle off into space, and return in, say 3 hours(as indicated on a clock within the ship). During the same time(pun intended) an entire day would have passed for your friend, yet only 3 hours have gone by for you.
So you just skipped a day and travelled into the future.
A far less pronounced example of this phenomenon is via the atomic clocks on the international space station, where time
is about .007 seconds slower than on Earth.


Furthermore, due to the immensity of space, light takes time to travel so when we look at the stars at night, we see things not as they are but as they were. Some stars may have long ago gone extinct and turned into supernovas. But their light, emitted wins ago, is only reaching our eyes just now. Amazing to consider that a star you see at night might not even be there anymore.

time is mind byproduct... thus time travel can only happen in mind through deep concentration and strong faith..

AWESOME POST!

I also saw some doc about how mass makes time slower and if we traveled really fast in theory time would move faster for us. Very intruiging indeed!
