Time travel? is it possible or is it just fiction?
I mean a machine would have to change the time and make a permenent rift and only scientific answers and some that make sense!

I am no scientist. I grew up watching time travelling in science fiction movies and tv shows. But I am afraid it will stay fiction: we are trapped in our time. And those theories like “some tunnels in the universe” are just speculations. But time will tell.

Hey there
look :
God created planets, stars, galaxies…and god created humans. but god didn’t create “time” , humans created “time” so it will be easier to schedule plans, go on date, and for everyday tasks. so if time existed by nature, I think it will be possible to create a time traveling machine.

I am not certain about the physics of going back in time, but there is certainly a logical problem with it – if it were possible, someone would have taken a time machine back in time, and shown the people he met how to buld that machine. Time travel would thus always have been possible. In terms of going forward in time, relativity does allow you to ‘travel forwards in time’, if you can leave the earth’s gravitational pull (time will move more slowly for you than for everyone else on earth). Similar effects can be obtained if you can travel at an appreciable percentage of the speed of light.

First off humans did not create time, we live in a 4 dimensional universe (length, height, width, and time), so don’t think listen to him about time not being part of nature. And according to the theory of Special Relativity time slows down when velocities approach close to the speed of light (called Relativistic Velocities). Using the equation for time dilation, we find that if a particle were to travel to the speed of light (which it must be a massless particle) time would in fact be zero. Thus relative to a person watching you travel, you would arrive instantly as soon as you left. If you went faster than the speed of light, you would actually turn time on its head making it negative. An observer would view you as arriving at you destination before you even left (which violates causality). If you were to increase this speed, you would eventually be able to travel back in time. Particles that can do this are called tacyhons. They are theoretical, and have not yet been found.
