because there is a theory were u cant travel backward up to were the time machine was created e.g if you made a time machine in 2020 u wouldnt be able to go past 2020. so if some1 does make a time machine the people would be able to come to our time, but untill then nothin is goin to happen

I was actually watching something on PBS the other day, and they were talking about this. They said that yes there is a future, and a past, blabity bla bla. But they said that you probably couldn't travel to the past, only the future.

im not going to be able to go back to sleep for a long time thanks.

Your very welcome.

Hope to see you in your dreams.

Time travel exist in your mind you can time travel in space is possible but some people don't know of it. I DONT KNOW WHAT its called but by traveling around the earthfor 12 months eqals to 10 years on earth. in space there is no virus or desises i dont think you even age in space.

If you think about this on a logical standpoint, time travel would be false in that regard.

Say a time machine were invented tomorrow. If you think about the time-space continuum, a loop is needed to make time travel possible. That being said, if the first time machine is created tomorrow, that would be when the start of a loop can form. There would be no possibility of being able to go past the original starting point of the loop.

Just how I believe about the concept.

Maybe they dont want to show they are from the future

What happens if you went back in time and you killed your mum before she had you, how could you be alive?

Any type of time travel is impossible because it would create a paradox

Well this is off topic kinda, but if you could go faster than light then you could for example : Run around the world and arrive back before you even left making there 2 of you or on the other hand, you traveled back in time
