The universe

xcrimsonxkissx · 04-27-2007, 08:59 PM

The big bang?! IS that how everything started, and if it is then what was there before it!?

Infinite space?!

What does infinate space mean!?

If its infinate how can there be a boundarie into the next universe.
I love this stuff (im a trekki! lol) but it confuses the hell outa me!

Anyone care to discuss?!

I love this kind of debate as well, mainly cos I'm obsessed with physics :p

I believe that the universe did start with the big bang, at least the present one,t hough I believe in an eternal universe, one which is forever expanding, slowing, contracting, then another big bang occurs, on and on for eternity, what came before that? I don't have a clue, maybe nothing, a completely unvaried piece of space time where nothing happened forever, until one tiny quantum fluctuation sent everything out of balance, or maybe something completely different from anything we can think of, personally I believe the former.

As for infinite space, and linking between universes, I don't see it as infinite space really, I think certain branches of string theory's explanations for this really are "elegant" and appeal to me, basically we're a universe of four dimensions, sitting atop a plane of many, many more dimensions, along with an infinite number of other universe, to link to other galaxies you'd have to punch through, into that many dimensional plane and through into other galaxies from there.

Just my rambling thoughts on it.

I like this kinda stuff too!
I've always been frustrated with the whole "dark matter" buisness! Any thoughts?

xcrimsonxkissx · 04-28-2007, 05:49 PM

OO dark matter like in northern lights?!

Cos in that dark matter is the same as shadow particles but if youve read all the books you'l realise that when they cxalled it dark matter was becaseu it was millions of years earlier than todays time and it was when they didnt know how shadows where formed, it was the church's way of controlling everyone.

Fuck i read Northern Lights to much! lol

if that's not the kind of dark matter you where tlking about then im sorry for my ramblings! lol

Erm I havn't read Northern Lights, the Philip Pullman ones? I've never got into those.

It's all connected with the Big Bang and the structure of galaxys. They think it's there 'cos of cosmic waves anfd stuff which indicate that galaxies...etc have much more matter than first seen/thought, and that the whole universe contains this...matter that can't be like seen with electrmagnetic radiation, but we don't know what it's made of.
Yeah kinda, like, the invisible matter that makes up the universe, like, most of it. Apparently like a lot of the universe is made out of it but...we don't know what it is! Like, the stuff in between planets and stuff I think (may be VERY wrong) but it dosn't reflectt or give off any radiation or anything, but we know it's there because of obervations of gravity. Something like that. We know the mass of dark matter is THERE but how we can detect or see it, or find what it actually is, well, we just don't know.
Also there is "dark energy" which is even MORE confusing, which accounts for most of the energy in the universe and the fact that all the galaxies are moving apart or expanding, it's crazy 'cos it's like density can change due to time and space! So it's effects can be different or something. Although just a theory it seems to be a pretty polular way of explaining the movements after the Big Bang in the universe. But again, it's "dark" so what the hell is actually going on there, well, we dunno!

Dark matter, although it can't be seen either by emission or reflection of electromagnetic waves, can be inferred from it's gravitational effects on visible matter, and it accounts fro a huge majority of the matter in the universe. The best idea I've heard as to what it is, is that it consists of elementary particles, which are too small toe reflect or emit electromagnetic radiation, hence why we can't "see" it, only its effects.
Much more troubling is the idea of dark matter, taking mass as equivalent to energy due to Einstein's equation, visible matter makes up a measly 4% of the energy in the universe, dark matter still only 23% , while dark energy, something which we have never seen and can only see the effects of, and which no-one can convincingly explain, amkes up a massive 73% of the energy in the universe.

elementary particales! they talk aobut those in nortehrn lights too!

fading-away · 05-03-2007, 09:25 PM

Hehe, I did get the feeling when I read it that Pullman was trying to work in as mch actual physics as he could

Yeah, thats what I was trying to say

I just didn't know the statistic. Interesting though isnt it?

I've never read them Pullman books. Any good? I just couldn't get into them.

fading-away · 05-03-2007, 11:04 PM

Hehe, I'm kinda obsessed with physics, hence why I'm studying it at uni next year so I have a load of textbook type books to puul all sorts of random facts from...:p

I haven't read them for quite a while now, so my opinion's not really up to date, but at the time (maybe 2/3 years ago now) I really liked them.

i quite like the stars, and universes that are out there.
They look amazing.

I'm not sure what to believe about how it was all creative, but to me its obvious "god" didnt have alot to do with any of it.

but the thought of how far out we can go is pretty extreme, the blackness isnt measurable by any unit we have. And it takes like a life time to get to pluto, so thatd be crazy to try get out to where the tellescopes can see.

i dont know where im going with this, but the stars are beautiful.
something i deffinately admire at night.

Confubbled.. · 05-04-2007, 02:56 PM

i watched a programme recently that explained the whole thing.the big bang,the stars, how water came to earth, how earth was formed, and all that.

it was amazing.can't remember most of it now but it was brilliant.i'm not really into science that much but i was hooked to the programme.

and mark i agree with you..the stars do look amazing.

Markme · 06-08-2007, 04:34 AM

One day in the future we are going to be able to do all the things that are on thoughs movies... and i hope to explore space one day... the stars would look even more beautiful out there in the darkness.

!-nessica-! · 06-13-2007, 06:50 AM

we're never going to have definite answers... technically we cant prove where anything comes from.. and its something people will spend the rest of time wondering..theres theories and they're all so complex and stuff its weird that people actually could think of something that smart.

its pretty amazing though..how insignificant we are and how much there is to know about everything that we'll never know.

and hopefully one day we'll all be able to go into space coz that would be so cool

such a good experience. i reckon anyway.

really though space is pretty much just that, space.
craaaaaaaaazy!
