I have the wormhole knowledge in my brain...:eek:
So did I til a big nasty man took it out. Now I can't even tie my shoe laces.Quote:

Purely theoretical concept. It exists as a passage between a black hole and a white hole, connecting them at the horizon singularity.Quote:

A wormhole can be produced if a gap in the singularity can be produced, which of course is impossible to do.
elaborate on white and black hole..Quote:

a bit off topic, but does anyone remember Sliders?
ever eat white castle??? that stuff can give you white castle sliders :DQuote:

oh you mean the show that they based that g@y jet li movie off of? actually that whole concept is part of one of the theories of time travel.. but anyways
Black holes, you probably know about already, but I'll summarize nevertheless. A blackhole is formed after a (usually large) star collapses upon itself due to its own gravity, forming a region of space of extremely high gravity. The gravity is such that light rays falling upon the surface of a black hole cannot escape it.Quote:

The entire 'mass' (not in actual sense) of the black hole concentrates towards a single point within the black hole, of infinite and gravity. This point is known as the singularity.
Now, the existence of black holes cannot be verified by seeing it directly, since it cannot be 'seen'. It can only be detected by the accompanying matter that it may be swallowing.
Just like a black hole allows nothing to escape it, a white hole allows nothing to remain inside. White holes, too, are a theoretical concept. A white hole will constantly be spewing out matter into space. It exists (mathematically) because the equations of general relativity are symmetric.
It is in between a black hole and a white hole, that your wormhole can exist. See the attached image...

Wow Mendhak !
I bet your a RIOT at parties ! :p
ROFL :DQuote:

Mendhak: Do black holes give off X-Rays? Or is that just an effect of the matter falling into it?
did you guys ever see that movie event horizon.. i always thought it was just a semi clever movie name.. but an Event Horizon is actually a scientific term.. it is the horizon on a black hole where no light can get passed.. and it is determined by the strength of the black hole... so imagine it as light is trying to escape the black hole.. and at a certain point.. it just can't go any further because of the incredible force.. and gets sucked back in...
but supposedly black holes actually can be seen due to the radiation they emit... not seen by the eye.. but there presence can be detected... in fact they believe that there is one not to far away in our galaxy
I thought it was a damn good film actually.
And yep, Event Horizon, since as you approach the singularity time slows down to a single "event" of some kind. Past the event horizon, nothing can escape.
Actually, given sufficient gravity, light can turn corners. They tested this by observing the position of certain stars when there was another star near, and when there wasn't. The observed difference was almost exactly that calculated :)
It may sound contradictory to the nature of a blackhole that it emits x-rays (which are in the electromagnetic spectrum, and shouldn't escape).Quote:

However, as the matter is accelerated and subjected to gravitational forces of the blackhole, they are heated to extremely high temperatures. The atoms then emit X rays, which can escape the surface of the blackhole, and that is what we receive.
Just to add to that, the distance from the Event Horizon to the point of singularity is known as "Schwarzschild Radius"Quote:

Don't bother pronouncing it. Just type it whenever you need it :)
there is still a lot that isn't known... and will probably not be known for a long long time... if ever (in the human races existance anyway)
black holes are contributed to a lot of weird theories.. most of which end up like this
"well if you went into a black hole, you could do this this this and this... but it would rip you to shreds and eat your matter first"
lol :D
And the size that determines when it will become a black hole is the Chandresekhar (or whatever) limit?Quote:

Been a while since I did anything on this :)
this is a sick shot

a massive black hole hidden at the center of a nearby giant galaxy that is feeding on a smaller galaxy in a spectacular collision. Such fireworks were common in the early universe, as galaxies formed and evolved, but are rare today.
Close... it's the maximum mass that determines it, known as Chandrasekhar lt.Quote:

Streaming out from the center of the galaxy M87 like a cosmic searchlight is one of nature's most amazing phenomena, a black-hole-powered jet of electrons and other sub-atomic particles traveling at nearly the speed of light. In this Hubble telescope image, the blue jet contrasts with the yellow glow from the combined light of billions of unseen stars and the yellow, point-like clusters of stars that make up this galaxy. Lying at the center of M87, the monstrous black hole has swallowed up matter equal to 2 billion times our Sun's mass. M87 is 50 million light-years from Earth.
I wonder if they got a 'shot' of the Milky Way black hole. I'd like to use it to scare kids :D
i don't think they do.. simply because it is invisible right now...Quote:

mendhak i know you know about this.. but i will post some info for others... correct or add on to anything i say..
it is all about the space/time relationship...
it is hard to grasp.. but when we look at things via tools like the hubble.. we are seeing them as they were.. not as they are...
for example.. the sun is 8 light minutes from earth... so when photons of light leave the sun... they hit us in about 8 minutes.. so theoretically (according to eistein) if the sun burnt out all of a sudden, we wouldn't feel the effects for 8 minutes, unlike Newton (i think it was newton) who said it would be instantanious..
but anyways... so if the sun (which is pretty close in relation what we look at with the hubble) is 8 light minutes... then the light that the hubble recieves from galaxys that are thousands of light YEARS away.. means that the light is just getting to the telescope now... so basically... when we take a picture of a black hole.. that could be what it looked like 50 million years ago...kinda weird huh?
i think they said the farthest back they have looked is 13 billion years?? i could be wrong on that one
i think am gonna go to "Black Holes 101"

AND your double posting skills as well!! :)
you are getting quite good at it already.. you must be a fast learner :DQuote:

Ah nuts. I noticed a spelling mistake as I sent it.
Thought I caught it in time.
:p
well i know you missed the quote button.. so here are a few other tips..
each post has an "edit" button... (of course you can only edit your own posts though)
and when you click the edit button.. there is a delete option at the top of the screen.. so you can either delete... or edit any of your own posts...
Yes I know about those.
:p I made another mistake on that last post, but caught it in time.
I am SUCH a perfectionist :D
Sooo ... if a worm digs in my garden, is it a black or a white hole ?
How stupid are you?! ;)
When worms dig in your garden its a wormhole!
Drop a pebble in each side
The place the pebble goes out is the white hole and the other place is the black hole!
