is it possible to travel in time, what are some concepts, theories which are yet to be explore to know more about time travelling.
It is possible! The twin paradox is a perfectly valid way to travel time. Just because we understand it, doesn't mean that it's not time travel. And travelling backwards in time is not contradicting any physics either.Since it is impossible, I don't think of it at all.
In the twin paradox, the twin leaves in the present and returns to the present. Only the passage of time was different for the twins.It is possible!

It is possible in principle to leave, to travel for 1 second, come back and be 5000 years in the future. That's time travel no?In the twin paradox, the twin leaves in the present and returns to the present. Only the passage of time was different for the twins.
I'm curious, how can this be done?It is possible in principle to leave, to travel for 1 second, come back and be 5000 years in the future. That's time travel no?
Time dilation. Just travel for one second for a speed sufficiently close to light. On earth, 5000 years will pass, while for you it looks like 1 second.I'm curious, how can this be done?
How would you accelerate an object to a fraction of the speed of light, slow it down, turn it around and accelerate it back to earth, and slow it down once again, all in one second?Time dilation.

That's an engineering problem. Physics says it's possible.How would you accelerate an object to a fraction of the speed of light, slow it down, turn it around and accelerate it back to earth, and slow it down once again, all in one second?
What about the forces on the body? That's a physics problem.That's an engineering problem. Physics says it's possible.
"Solar" (i. e. stellar) sails. Although it'd take considerably longer than a second. The current engineering problem isn't achieving a significant fraction of light speed, it is escaping or resisting micro collisions with cosmic dust or anything larger.How would you accelerate an object to a fraction of the speed of light, slow it down, turn it around and accelerate it back to earth, and slow it down once again, all in one second?
As a question of terminology, what is the definition of "state" when we refer to "travelling backward in time" ? - which presumably means travelling to some previous "state" of a system in time.It is possible! The twin paradox is a perfectly valid way to travel time. Just because we understand it, doesn't mean that it's not time travel. And travelling backwards in time is not contradicting any physics either.
I enjoy it, but I wish I could do it a little slower.what do you think about time traveling.

No they are not, you are going slower than you used to.uh huh, Im convinced that the years seem to go by faster than they used to![]()
naaa, life is just passing quicker, everything is at a more hectic rate than 30 - 40 yrs ago.No they are not, you are going slower than you used to.
