You go 1 second in the past, you are 200 miles from where you used to be and now you might be 200 miles underground or 200 miles in space. Either case, you don't have a good outcome🙂
only a problem if the time machine pops out of existence a it's start point
and then re-materialises at it's destination.
Time machines that don't do this avoid this problem.
For example H G Wells time machine remains fixed to the earth as it moves
backwards and forwards in time, and thus will go wherever the earth goes.
Originally posted by sonhouseIn that case, so am I, and so is my table. Remember that Wells' machine doesn't pop from one time to the other, it only speeds up time inside itself, or runs it backwards. It's like a tape deck fast-forwarding or spooling back, not like a grammophone user lifting the needle through another dimension to the next track.
That makes it more than a time machine, it is also a space machine.

[b]If you travel from one point in space to another point and this is done instantly, then you have a space machine (analogously), but is presented with other names, like quantum jumps, 'beam me up, Scottie', and such.

Teleporter is the usual word.
[b]A true time/space machine is when you instantly are traveling from a four-dimensional point in the space/time continuum, then you have a true time machine, where the space coordinates adjusts to the point in the rotating coordinate system we have on earth relative to a fixed point in space so it will be safe to travel i ...[text shortened]... 't travel back in time, but rather he is travelling forward in time, but remembering the future.
Originally posted by FabianFnasWell, that would be with our level of physics. I wouldn't count it out for folks a million years ahead of us in the technology game somewhere is some galaxy or other. It's a rather large universe, so I'm told🙂
"H G Wells' machine does not transport you instantaneously, but rather takes you along a line through spacetime."
His machine wouldn't work in reality. It's fiction.
