One thing I have never heard about time travel when people presume to theorize on it, is if one were to go back in time, say to kill Hitler,-by going back in time, wouldn't one have to wait for the earth to get there? Meaning as time moves forward, we are occupying a specific place in the universe. The Earth moves at umpteen thousands of MPH; The Sun moves around the center of the galaxy at blistering speed as well as our galaxy hurtles through empty space at unbelievable speeds. By going back in time, you go back from where you are at, thus arriving where the Earth has yet to get to...follow? Thusly concluding that even if Time-travel were possible, one might be surprised to find a lot of empty space! Has anyone heard anything on this?

But if you were to go back in time, then wouldn't you be going backwards? With a species capable of time travel, i would think they could retrace earths position in space at any given time....why would there be empty space? The earth is always in a certain place in space, be it present or past...now if your talking about going into the future I might agree....

Not if you imagine all existance as a roll of film with everything through every second of time from the Big Bang to the End of Existance recorded on it.
Then time is simply the unrolling or 'playing' of this film and to travel back or forth along it would be as simple as rewinding a video.
Of course, the problem then arises - how do you 'pull yourself out of the film' and 'get back into it' when you have done your travelling.

Hi, Can't say I blame you. As ideas go it was a pretty wild one!
I think what I was trying to do was free up ideas and encourage 'outside the box' thinking.
The trouble is we can only judge reality through our limited human senses and consciousness. There are things 'out there' that simply don't exist for us (except intellectually, after they have been discovered.)
Things like the sound of the 'silent' dog whistle, which is outside the range of our hearing - but is quite obvious and ordinary to a dog.
Or the existance of bacteria or viruses or genes or DNA. Invisible and non-existant to our normal senses until a leap of imagination on the part of a great mind invents the electron microscope to enable us to see them.
At the other end of the scale man is totally non-existant to ants. The ant's range of vision is just too limited to encompass a complete human body. A part of a finger or bit of a shoe is all it could ever know of us. And yet we are here, all around them.
So what I guess I'm suggesting is that we need to be open to the possibility that there could be all sorts of stuff 'out there' beyond the limits of our senses and present knowledge that might one day be discovered through ever-advancing technology and more powerful machines.
Even magnetism and electricity were magical and fearful forces not too long ago!
Every law of physics, every law of nature, every law of everything has been set down by man. And each one should be up for respectful challenge.
Something I heard, summed it up for me: 'To keep his sense of wonder a man must lose his sense of certainty.'
Sorry to go on so long! Just trying to set down where I am coming from.
Cheers, Sponge.
