Time Travel...

If it was going to happen, someone would have come back by now.

If one has been invented future Ffoeg would have sent one back in time for me

[QUOTE 2666087, member: 1314"]Basically, that's what Hawking said. I'd've come to that finding with less funding, mind.[/quote]You can't go back to a time before your time machine existed - that'd create a paradox.

but we are traveling thugh time, at about the rate of one second per second

It would also ruin strava. :P

I have a theory that UFO sitings are test flights of time machines. But then I did go to a lot of raves in the 90's

Time travel is so déjà vu!

But isn't it all about speed? We just don't have the technology yet to travel fast enough...that's my ignoramus understanding of it anyway.

Of course they would. But what makes you so sure they haven't ?
IF, it were possible, (and I think that's not likely) it wouldn't be the kind of thing your average bod would have access to. I imagine it would take zillions of watts of energy and a machine that cost the likes of the Cern thingy.
So anyone who did arrive from the future, would I suspect be a scientist/researcher of some kind. Probably fully aware of the dangers involved.

Also, any depiction of time travel slots someone exactly in the same place on the planet but in a different time, but the Earth is spinning, it's moving around the Sun, which is itself spinning around the Milky Way, which is moving.
So finding the exact place to set a body down at any time in the future or past would be kind of tricky. Imagine materialising with your legs buried in a lump of granite.

That's how I feel by the end of a week at work!

I don't see why it can't be possible.
You can get round the whole paradox thing by not interfering in the past at all - a Temporal Prime Directive, as it were, as in A Sound of Thunder, amongst many, many others. I've got no idea how time travel could be done, but I'm reminded of Arthur C Clarke's maxim - "If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong."

Thats how I felt after last weeks sportive.

[QUOTE 2666080, member: 1314"]...will never happen according to Stephen Hawking. He's right I guess, but I'm disappointed.

What do you think?[/quote]

Just proves how clever he is, a very talented man, especially how he can speak without moving his lips
