If, and big if at that, that were possible, then you'd still have to contend with the "space" portion of time travel. Consider how much our earth has moved from today compared to yesterday, then extrapolate that to say 1000 years ago (for the sake of the argument). On top of that, factor in how much the solar system has moved in relation to the galaxy, and how the Milky Way has moved in relationship to the rest of the universe in that span. That's a lot of movement. In essence, the time traveler argument becomes as improbably as the space alien argument. So much energy to go from A to B (and don't say "worm holes") and for what reason.

I'm curious to know what your take on all of this is, and why you harbor it as such; you seem like a fairly logical guy who wouldn't buy any of this pseudo science bullshit. And why you've been coy with the China UFO references. Do you know/think you know something, or are you just trolling? Maybe I guess I just don't see where one gets a kick out of dicking around with people on such topics "just for the lulz."

A time-avoiding craft.

I'm just trolling.

That is incorrect.

Are you aware of the pollution problem that China has?

Reflection of street lights off of a thick smog layer?

I'd buy that.

Especially over Hung Joe.

You know who I feel sorry for? The poor bastards on the planet that we find in about 250 years.
Honestly, I have no doubt in my mind that there are other, more advanced, civilizations, and that they send probes here. I do have my reservations about whether they would try to come and take our planet, because if they've been watching, they would know that we'd blow the MFer up before we'd let anybody come take it from us.

No, it is a helicopter.

A 234UT in the foggy skies over Hung Joe!

Can time be traveled? No.
Can it be bent? Yes. Right along with space.
To travel extreme distances, space-time will have to be compressed in front of you, and expanded behind you. In essence, you could travel faster than light, and never break the theory of relativity, because you really would not be moving at all. This also solves the problem of leaving earth for 5 years at 95% the speed of light, and returning to earth 40 years into the future.
This is not science fiction. Scientists are already speculating on how it will be made possible, and the theory of relativity says that is, indeed, possible.

I don't know what any of that means.

Hangzhou [hungdzhue] = Hung Joe. 234UT = helicopter! Maybe BV-234? Who knows!

douglas adams called. he says you stole his idea.

Yes, because humans would show no pity on another life form, especially if it was inferior.

I, as well, have no doubt alien life form exist out there. If you just run simple calculations the possibility another life form exist is very high. My only reason as to why they would come & colonize our planet is because they are somehow out of resources and need a new planet to live & harvest. Obviously, if their tech and their intelligence is superior to ours, they would probably know it's probably not the easiest place to colonize because they would face resistance. Might just be easier to find another planet with less resistance and free to do as they please. Maybe war & extermination is not their goal since they would be highly more advance than us.

Genetically engineered monkeys who do the bidding of their humanoid masters FTW!
