0% in my opinion. Time travel into the past creates impossible paradoxes. In the classic example, if you went into the past and killed your grandfather, you prevent your own birth and therefore would’t be able to kill him in the first place. And Stephen Hawking has said if time travel is possible, where are all the tourists from the future? He also demonstated in one of his books (a brief history of time maybe?) that using time travel you could make a bomb that could produce infite energy, destroying the universe. It uses a wormhole that copies a single photon infinite numbers of time in an instant. Time doesn’t really have a backward and a forward anyway, it’s just a way to measure change.
Yes, I screwed up. It should have read blue marble.
I must have been thinking of little green men. ;)
Yup!
Back atchya.
Well, obviously, if you set out to kill your grandfather, it would turn out that you weren't able to do so - perhaps you were hit by a bus on the way to his house and buried unidentified in a pauper's grave.
Perhaps Dennis Kucinich is withdrawing from the race and they’re here to pick him up (the human race, that is).
On earth there are estimated between 1.5 and 1.8 million species. Only one of which has developed the ability to use radio or space travel and then only for about 100 years of there existence. If we assume that there are millions of other planets in our galaxy with the same or similar conditions then the likelihood of encountering another species with intelligence like our own approaches non-existence. It just ain’t gonna happen.
Haven't you been following the campaign? The Earthling is trailing...
Well, the cassic example is just the easiest to explain. Every scenario involving (reverse) time travel can always be shot full of holes, because it violates the law of causality.

Agreed. Of all the theories to explain the unexplained, this is the one most deserving of a tin foil hat and for the very reasons you noted.
There are explanations for mysterious events, we just don't know them yet and may never know some. I don't rule out alien life but do "time travel"
Yes, that’s a typical open-minded point of view. But just to beat a dead horse, I think even the possibly of time travel can be ruled out. There are physical laws which can never be broken because the result is impossible. 2 + 2 will never = 5. If I have a time machine that can send something back in time 5 minutes, I can create some pretty impossible results based on what just happened 5 minutes ago. If nothing happens, for example, I can send a quarter back. So where then did it go? If I did get one 5 minutes ago, I can decide not to send one, so then how did the other one get here? Or I could send the same quarter back again, in which case I should have gotten 2 identical ones originally. And if I did, I can send them both back again, in which case I should have gotten 4. If I just decide however many I get, I’ll send them all back, then I should get an infinite amount. You see, the problem is you can imagine time travel is possible in general, but it breaks down if you imagine specifics.
Why would an advanced race want to pick Dennis up?I’d leave him right here.
"Bullions and bullions!" Carl Sagan to Johnny Carson on the Tonight Show. Seems like bullions of years ago.
Funny! L0L!
> Time travel into the past creates impossible paradoxes.
They very notion of “time travel” presupposes that time
is something (a “4th dimension”) that exists independently.
It may be just a human concept for quantifying motion.
The past is not still going on somewhen.
It is over.
I lived nearby at that time. I don’t know if it was the same incident, but a neighbor knocked on my door (well, my parent’s door, i was a kid) and asked me to bring out my telescope. i went outside with this thing that was no more powerful than a pair of binoculars, and this object that we saw was too bright to look at through it. Everyone on the street came out to watch.
I used to be the single biggest skeptic on this subject on the planet, until, that is, one day in late July of 2004 in SW Wyoming.
My wife and I were on our honeymoon and while traveling in SW Wyoming we saw a a craft that was so unlike anything I'd ever seen it was nothing short of amazing. Both the wife and I are pilots and we are familiar with just about everything that flies. The thing we saw was in broad daylight, less than a mile away, 500' off the ground and moving at what I would estimate was about 350 knots. It was about 100' in diameter, black and silver in color, with a row of fairly large circles (lights?) around the bottom of the circumfrence of the object. It looked sort of like one of those helium balloons that many have tried to fly around the world, only it was moving sideways at 350 knots. It was a warm day and we had the truck windows partly down. This thing was silent, but left a shadow on the ground as it passed between us and a small ridge in the distance. The really weird part is we had two cameras sitting on the seat in the truck between us and neither of us grabbed for either one. In fact, it was about 30 minutes later before either of us even commented on what we'd just seen. It was really, really strange. I'm familiar with all currently known military aircraft, iow, I know the difference between say an F-15 and an F-16 at this distance. I'm also very familiar with virtually all civilian aircraft. This was nothing like either of us have ever seen, before or since....
I have no idea of the origin of this object, but if this thing was military, those boys have been doing a damned good job of keeping it a secret.....
I’ll guess and say it’s a Skunk Works type project.
If God wanted to start life on another planet, it doesn’t matter if there are billions of them or just two — He’s start life on another planet.
C.S. Lewis himself didn’t know whether or not alien life existed. I don’t think any Christian can say that there is absolutely no alien life in this universe. The question is: Do they need a Savior?
