If I built a time machine and went back in time, would the time machine...?

Question

disappear because I went back into a time before I made the time machine?

Answer 1

No but it would be parodoxical no the less

Answer 2

Try then come and tell me.

Answer 3

This is a classic question it gets asked all the time. Assuming you could power the time machine without a plug, using a hydrogen fuel cell or batteries, no. The time machine would not disappear. Matter can neither be created nor destroyed. This is the simple answer.

Answer 4

No, because since the time machine is from coordinates {x, y, z, t0}, and you would be in {x, y, z, t1}, the time machine would still exist.

Now, if you went back to {x, y, z, t1}, and killed yourself, then you wouldn't have existed at {...t0} to create the time machine so you couldn't have gone back to {...t1} to kill yourself. so then you and the machine would exist at {...t0}, so you COULD go back and kill yourself.....

And around and around and around.....

All of which would probably violate causality and entropy...

But that's another question answer...

Answer 5

Maybe you should ask the question "Will I disappear because I went back before I was born?" or suppose you accidentally landed your time machine on top of your grandfather and killed him before he even had any children.

It may be possible to SEE into the past - but not to BE there, because wherever you go - there you are.
