MajinVegeta Posted March 17, 2003 Posted March 17, 2003 This SO cool: http://www.physics.hku.hk/~tboyce/sf/topics/wormhole/wormhole.html what do u guys think?
alt_f13 Posted August 17, 2003 Posted August 17, 2003 Wow... I always just assumed there was such thing as negative energy, and now I read this... In my ever-pessimistic view of the universe, the entirety of everything ammounts to exactly zilch. It seems like commonsense to me, that in a universe surrounded by nothing, with a whole bunch of something in it, that there was some sort of antiverse (not anitmatter universe but something in the universe that could account for the sudden emergence of energy/matter). What does everyone think of that? Seems like everythings natural state is equilibrium to me.
JaKiri Posted August 17, 2003 Posted August 17, 2003 I have the copy of scientific american that's taken from. It has a caveman on the front.
alt_f13 Posted August 17, 2003 Posted August 17, 2003 heh, a further thought... If the universe is indeed made up of nothing, the center of the universe might be comprised of (is that the right word for what im about to say?) negative energy. If that were the case, the universe might have further reason to expand forever, seeing as negative energy also has negative gravity (that was my understanding of it anyway). Edit--------------- Might gravity have the ability to draw energy from nothing, producing negative energy?
JaKiri Posted August 17, 2003 Posted August 17, 2003 The universe has no centre, and as to the gravity comment, Whut?
alt_f13 Posted August 17, 2003 Posted August 17, 2003 if the universe was created by the big bang, the site of the big band would be the center, as that is what everything is moving away from
alt_f13 Posted August 17, 2003 Posted August 17, 2003 why? who are you and what do you know? I have always read that to be true...
JaKiri Posted August 17, 2003 Posted August 17, 2003 I'm a physics student, and if the universe has a centre a whole swathe of physics gets unhappy.
alt_f13 Posted August 17, 2003 Posted August 17, 2003 how so? and if thats the case, how come every galaxy we can see is accellerating away from us.. like an expanding sphere?
JaKiri Posted August 17, 2003 Posted August 17, 2003 You're assuming that we're the centre of the universe. We're not. Every galaxy is accelerating away from every other galaxy. If there's a centre of the universe, then not all rest frames are equivilent, which rather kills special relativity, which is a very nice theory and everyone assumes its true and to the best of our measuring it is. ps. Empirically, of course, there isn't a center of the universe EITHER because we can never find the edges.
alt_f13 Posted August 17, 2003 Posted August 17, 2003 what the hell? no im not in an expanding bubble, every part of the bubble is expanding away from every other part
JaKiri Posted August 17, 2003 Posted August 17, 2003 Sorry, yes, I'm wrong about that. (/me puts down the beer) However, that doesn't devalue the rest of the post.
alt_f13 Posted August 17, 2003 Posted August 17, 2003 what about the cyclic universe theories? if there is no center of the universe, where is everything supposed to converge?
JaKiri Posted August 17, 2003 Posted August 17, 2003 Well, under current reckoning the universe won't converge, so that's pretty immaterial. They also don't have to collapse around a centre, just around any point which may or may not move. The final point doesn't have to have been the centre.
alt_f13 Posted August 17, 2003 Posted August 17, 2003 well thats assuming that the original explosion wasnt uniform.. and it wasnt so i guess that makes sense.. i do like the idea of myself appearing an infinate ammount of times for the rest of time... but also, as ive read, if the universe doesnt converge as matter, it will eventually disperse into pure energy when it then again gravitates towards a single point, and the process repeats itself... is that anything close to what you are learning now? this was a fairly recent document by some really accomplished physicists
alt_f13 Posted August 17, 2003 Posted August 17, 2003 hahaha, ive just done a song similar to what we are talking about now http://www.djglacial.com/red.html its there if you like trance, but its unfinished and dont make fun of my voice, it was 4am i recorded it haha
JaKiri Posted August 17, 2003 Posted August 17, 2003 Current information suggests infinate expansion.

alt_f13 Posted August 17, 2003 Posted August 17, 2003 i may know what its refering to, i know the A-team, MR T was my childhood hero
JaKiri Posted August 17, 2003 Posted August 17, 2003 Unless you frequent #planetarion on irc.netgamers.org, probably not.

alt_f13 Posted August 17, 2003 Posted August 17, 2003 o_é thanks im gonna find the bpm of that bannana of yours, its dancing to the beat
alt_f13 Posted August 17, 2003 Posted August 17, 2003 Well what you think about my theory of the Universe equalling zero? If that were anywhere near true, it would also be creating extra energy that would push the total mass of the Universe above zero. Thats what I got from that document above anyway, a positive energy biproduct. Perhaps im wrong there, I saw something about how it doesn't violate conservation of energy. I'm taking another look.
