With my 112th post in this thread, I'll ask you to update me on what you learn.

i just missed it.

He is able to move all his extremities, so thats good

hey dark, what do you know about time travel?

 

[naslundfan19]

No. I mean, getting into my room isn't a problem. It's on the first floor and the window doesn't lock, so I can climb in (and I did today), but it's the $200 fee.

Tomorrow I'm going to the ES department and asking for a metal detector.

$200 fee is not good.

Yellow Lifesavers candy are the best.

hey dark, what do you know about time travel?

There are three types of time: proper time, coordinate time, and spacetime interval. Every object has its own proper time, and that includes humans. So if a person moves at relativistic speeds, that individual's proper time will be slower than the coordinate time of an inertial reference frame in which that person is moving. Consequently, if a person were to travel at a speed approaching the speed of light, that person could circumnavigate the universe in 58 or so years, according to the individual's proper time, but several hundred thousand years would have elapsed on the essentially inertial reference frame of Earth, and when that person returned to Earth, not only would none of that person's friends or family be alive, but the Earth itself would likely no longer exist.

So, that's what I know about time travel.

No indeed.

Was this you?

Nah, dude, red.

ok well i do know of the stuff you were talking about. traveling in space and what not and traveling in general slows down your time. kind of like just not aging though. i was just asking because this guy on tv was on the colbert report talking about it. it blows my mind. however it seemed like he was saying a lot of the math behind it contradicts itself.

 

[Darkstone42]

Was this you?

Haha, yes, yes it was.

Interestingly (and unfortunately) enough, due to a strange debate about the original artwork in the Winnie the Pooh book series that inspired the Disney cartoons, concerning the masculinity or femininity of Christopher Robin in those illustrations (he looked like a girl), and since my first name is Christopher, all of the girls in my research lab in the fall have taken to calling me Christopher Robin. And so has my girlfriend, who was a main participant in the original discussion, back before we were dating, and who is in Budapest with my fall research group right now.

I don't fight it because it beats my new nickname of "Sickly Bear," and my old nicknames of "Stoner" and "Gonorrhea Boy" (because of staph infection on my armpit), and because I got called Christopher Robin quite a bit in grade school as well.

I don't know enough about the math to say one way or the other, but I do know it's very odd, and deals a lot with the way you set up your reference frames.

alright im out. later.

Sleep well! Later!

So, I can't just pick up a DeLorean, hit a certain speed, and pick up a sports history book in the future to get rich when I travel back in time to the present?

Bummer.

That's pretty much it. According to the believed laws of physics, you cannot travel back in time. Only forward.
