ok..i really wanted to answer to this thread and to see your guys' posts..but there's just too much to read and not enough time. so if i say something you already said, that's life...

so we should think twice before answering cause if we say "yeah, go into the past and kill those nazis and people will never have to deal with i dunno communism and such" ... if that happened, we would never know what a negative impact communism and fascism and co have on our lives and people would try it again and the history would repeat itself even though a part of it would've been "erased" by us.

If you like all the Quantum Theory/String Theory type stuff then you should read The Elegant Universe. It makes your brain hurt but it's worth it. If you can't be bothered to read the book, just watch the TV series:

If I could go back in time and kill anybody I'd sort out Stalin first. Most estimates for the death toll are between 8 and 20 million people. This seems to have gone largely unnoticed.

Sh*ttin hell, jib that just completely messed my mind up... I can bet you Ill be stuck here trying to get my head round all that all night. Ha twas fun though

erm..
 

Right a) I wouldn't kill Hitler cause its whats made today today and today is what matters, plus its given us history etc etc.
B):
*sits quietly, brain melts out of ear* thats some complicated stuff giving me a headache trying to think of it.
C)
There was talk of some pie?

You're making the error of modelling the universe like a balloon. You partially inflate the baloon, it's a certain size. Blow it up some more and it expands to fill the space around it. The expansion of the universe is the expansion of space-time itself.

The way I understand it (and I'm probably completely wrong) is, everything is expanding (even the atoms etc that make up everything we see). Ah, you say, so why haven't we gotten any bigger? We have. Get a ruler and carrot. Expand both by a constant and measure the carrot. It's the same as before. So how can we measure that the universe is expanding? We don't use a ruler, we use redshift. From our frame of reference galaxies appear to be getting further apart. We can tell this because the wavelength of the emitted light is strecthed toward the red end of the electro-magnetic spectrum.

I think m'lady was referring to the theory that since 'the big bang' (i believe in God not that so.... anyway) when everything exploded into....well whatever was or wasn't there in the first place, it is still expanding from the original big bang.......WAIT A MINUTE...what is it expanding into? think of the big bang, then try and picture it expanding into nothing (this is what Jibb was talking bout) how is that physically possible, ouch.

I'm well aware what she was talking about. However, you have mistakenly pictured the big bang as an explosion, with a centre and a blast radius. You have to remember that before the big bang there was no space. The big bang is the unfurling of space-time, the very creation of the dimensions you see before you. It is apparent that unfurling process has yet to finish.

Anyway, back OT, if Hitler was killed, it is fair to assume the USSR would have attempted to take over much of Europe. They were only our allies because we had a common enemy.

yo, where do satanists go when they die, son? cant get my head around it son, quantum physiks iz easy compared to dat sh*t.

yo son, if you wanna get f*** up, just heff on some paint thinnner. that **** will get you f*** up good son.

Hmmm.. hell maybe ?
