Bop Spacey

[Bop]

I love learning about the stars, planets, space in general- post an interesting statistic or fact about outer space... Wow me with your knowledge about the great beyond or your ability to search for cool space facts-

btw: you don't just have to list- this is an open ended discussion so feel free to talk about space phenomenon... WHAT THE HELL IS ANTI-MATTER?!

[Xerxes]

I thought that the recent big story about the average color of the universe being a pale pastel mint green was fascinating... especcially because I'm probably painting a wall in my room that color

[n_ick2000]

Antimatter is the opposite of matter.

As far as space phenomenons go, how do black holes exist? what's on the other side of the universe? where did the big bang come from?

[edit]Just curious, Bop, are you in to Star Trek TNG at all? If so, explain what a modified inverse tachyon pulse is and how they can create spacial anomolies.[/edit]

I don't claim to understand it though.

I myself would like to work in space someday. They're going to need lots of techs up there sooner or later.

All I know is that the Earth moves around the sun, the moon moves around the Earth, and that you only exist for a little while compared to the universe.

[henry3k56]

Too many things goin' on, so little time to worry.

Black holes can be detected by them pulling crap in. Dust particles from nearby stars get sucked into the black holes. When eh dust particles get going really fast and really hot they release x-rays, which can be detected. Also, it affects light coming to earth so weird effects occur when a black hole moves past a light source (star).

Do black holes lead anywhere, or do they just compoundingly pulverize things until they are nothing?

Basically yeah. They tear atoms apart, and everything we know that exists.

[insomniac]

it really doesn`t seem true to me that the universe is infinite...i mean,it has to end somewhere. what if the milky way,and all the surrounding galaxies,and everything in between here and the farthest we`ve ever been able to reach with our super power signal things,are just in a humongous mirrored bubble. i mean,what if the signals just bounce off side to side making it seem that our universe is infinite,but is really just glassed in. ok,i have no idea what i`m talking about,but this kind of seems logical. tell me if i`m sane or not.

[Bop]

So are there things which have a way to warp, expand, retract- time and space, so that huge leaps in time and space can be made?

[henry3k56]

Its all theoretical, space can't be justified by what we think of on Earth.

[Rob Weee!]

To coin a phrase:If we are the only ones here
it seems like an awfull waste of space.

I've wondered the same thing myself, but one question bothers me- if space is finite- it must have a boundary; what lies beyond that boundary? Something must be holding our finite universe... it is all very intriguing.

Not nothing- it has been proven that Blacholes emit a type of radiation.

A black hole is simply a body with such a high escape velocity that nothing can get out. That is the best and most concise explanation- and it is discussed in Steven Hawkings new ook "The Universe in a Nutshell"- which was aboslutely delightful.

[nature spirit]

in fact you come to some end where physics and philosophy coverge.. what are the limits? what's beyond? the time factor? space factor? how could you conceive if there's a limit? if so what's beyond? if not, how possible?? this is really beyond the ability of the mind to think. that's why some project to theoretically substract the factor of time and space, or simply to insert another factor which is the no-limits even if it can't be fully perceived with our limited minds.

I'm fascinated by the theory of vibrating cords, which states that the matter is nothing but a vibrating energy, and the way it vibrates defines the way it exists. wow.

[Bop]

My fascination with space far exceeds my knowledge of it; excuse the dumb ass question: but wasn't there a whole conspiracy a while ago stating that pluto wasn't really a planet at all? And while I'm out there- didn't they find what they thought was another planet just beyond pluto? Whatever became of these stories?

[nature spirit]

Bop.. no question at all is a dumb a.. one

actually I'm not much aware of Pluto's issue, but I think it's just a story, as you said, since millions of amateur astronomers can prove that (unfortunately Im not one of them... at least not equipped)

voyager2 caught some interesting infos of Pluto's before it headed out of signal into the infinite darkness beyond the solar system..

Interesting fact. If, in terms of spatial distance, if a star is behind a black hole relative to the Earth, you get an effect called lensing. We on Earth recieve multiple visions of the star because the light gets bent and distorted by the blackhole. I can't be arsed to find a pic, but trust me, it looks way cool to see a mirror image of something in deep space.

RE: Pluto. There is a theory that Pluto is really just a comet that got stuck in an orbit around the sun closer than normal. As you may be aware, there is an enormous cloud of comets surrounding the solar system. The theory goes that Pluto originated here (unlike the other planets, that were formed by gas expulsions from the creation of the Sun), and used to orbit the Sun in the normal highly elliptical orbit common to comets. For one reason or another, it got trapped, and kinda decided to hang out here. That'd explain why Pluto is solid and mainly ice, when all the outer planets are gaseous.

Planet X. That was a theory to try and explain Uranus and Neptune switch places everyonce in a while. They reasoned that some large planet must be exerting a strong gravitational force on Neptune, drawing it out further, while Uranus maintained it's normal orbit. They thought it had to be another planet beyond Pluto, because Pluto is too small to do much gravitywise.

The 'end' of a black hole is said to ba a singularity where everything gets destroyed.

Isn't it kind of odd that in one cubic centimeter of nothing there is more energy than in the entire universe? Mind blowing but true

[james]

er, phily baby, how can there be more energy in a black hole than the whole of the universe? matter is energy bound by information, therefore there might be more energy than is *available* in the entire universe, but if we were to convert all our matter into energy there would be, well, a lot!
Incidentally, matter-->energy conversion is how photon torpedoes work in Star Trek. They bring matter and anti-matter together, and the resulting annihilation reaction releases huge amounts of energy.
And no, I don't know how quantum torpedoes work, or modified inverse tachyon pulses, cos they have no theoretical foundation whatsoever!

[13_shadows]

Although I don't know much about space or theories of it, I do find the topic exremely interesting. My boyfriend is a Star Trek FANATIC!!! and I usually watch it with him. Every question that has been raised so far I've asked and he's known the answer to (bastard LOL) like planet x and anti matter (like when matter and anti matter come together they create and enormous explotion, and leaping the ship into warp, or something like that), anyway...I've forgotten what I initially meant to say...I babble too much...

[fwgx]

Not in a black hole, in normal space where there is no matter, going by our present understanding on the ammount of energy is in the universe in ordinary matter. I know. But then again the fact that matter is only matter when it is being observed it weirder.
[e]It acts as a wave instead of a particle[/e]

[Bogger]

According to stephen hawkins, travalling through space faster than the speed of light is possible in theory. The sides of black holes cause anything that comes close to vibrate at a hugh rate, in the side of these blackholes rips of tears seam to appear now and then, he said that if there was another worm hole of the exact same size density then it could be possible for an object vibrating to pass through one of these tears and pass out into the other black hole through what he calles a worm hole. It's a theory that he worked out, from where he got the idea i don't know. I just remember reading it in the paper one day.

[and1k]

In some Black Holes, it is theorised that they join up with White Holes, holes that spit out matter, to form a wormhole.

Plus: Based on the speed of orbit of the galaxy, it should spin out and become very much larger very much faster than it is at present.
They think that this is because of something called Dark Matter that is so heavy that it keeps the galaxy together. They set up an experiment that would detect dark matter flowing through the Earth's atmosphere, but I can't remember how it went.

And: They think that there are massive black holes in the centre of the galaxy, and that the entire galaxy is going to be eaten by them whenever. They also think that the galaxy is expanding.

Did that make sense?

Here's a mystery for you: Why does the smilie panel change size every time I refresh the page?

and1k.

[fwgx]

Probably ie reading the html differently each time. There is more dark matter than erm...non-dark matter in the universe. I think that's what I was talking about earlier.

[Bop]

What are worm holes anyway? Please explain in terms I can understand.

[rm']

I don't think a wormhole is a thing so much as it's a phenomenon. It's what some physicists think happens to matter as it gets sucked into a blackhole. They theorize that it gets spit out of a whitehole, whose existence still hasn't been proven.

[Bogger]

a wormhole is what a wormuses to take a crap. Yes I know i'm ignorent but then again who cares.

[rm']

I'll tell you what a wormhole is. I just made a post in GD, but the thread got moved before I hit submit. So I ended up in another forum. Freaky, eh?

you can find one in an apple..

Now that would be what I'd call a tasty apple!
