Question: What if, the universe is multidimensional, (2 dimensions), and a black hole links the 2 together!.!.!.!.!?
This black hole does what it does, and sucks up everything it can, till it can't take anymore!. When it cant take anymore, all the shrunken matter that is compressed - mind bogglingly small, then explodes, in like, a 'big bang'!. Hence why the planets / galaxies are always in motion away from each other, yet getting slower!.!.!.

Interesting thought!?!? Feasible!?!? Thoughts, anyone!?

Best Answer - Chosen by Asker:
Your question is faultily worded (for example, "dimension" usually has a different meaning in physics than what your thinking, because the universe IS multidimensional (4 that we are sure of))!.

Nitpicking aside, I think the entity closest to what you are referring to is a wormhole, and such things are theoretically possible: http://en!.wikipedia!.org/wiki/Wormhole

It doesn't connect us to another universe, but it connects two regions of spacetime to eachother!. Wormholes are the theoretical basis for the notion of time travel!.Www@QuestionHome@Com

Um, there's a lot of problems with that theory!. It would take a lot of time to explain and probably a chalk board too!. Basically, if you're interested in such things, I advise you to take some physics classes, or at least watch the part of the Elegent Universe Nova special that discusses general relativity!.

But here's one monkey wrench that was thrown into a lot of scientists gears 10 years ago!.!.!.

The galaxies are in motion away from each other, but they are actually getting faster, not slower!. The forced physicists to rethink the big bang!.

There is currently a proposal not too unlike yours though!. In that idea, there are two universes, parallel dimensions, essentially!. The two are linked together through an unseen dimension!. Gravity leaks between them!. And this is the reason why gravity is so much weaker than the other forces!. Not sure this theory is feasible, but I know it was on the table at least as of a few years ago!. It's a variation on superstring theory, more advanced than general relativity!.Www@QuestionHome@Com

What if the FOUR dimensional world had only 2 dimensions!? Read Flatland by Edwin Abbot!. I didn't know there was a point where a black hole couldn't take anymore!. Yes the big bang could have come from a Big Crunch (google it!) but THAT is NOT a black hole!
Congrats, you have gotten where it took scientists all the way to the 1970's to REJECT, except for the dimensions and the black hole business!.

what you are describing is the big bang!. everything is accelerating away!. there is great probablilty that there are over 7 dimensions, but our senses limit us to observing 3!.Www@QuestionHome@Com

then that would mean i could think of a better way for our universe to be shaped and the functions it would contain would be the ones we already want and understand and would never write about for pleaseure becuase they are exactly what we want them to be!Www@QuestionHome@Com

I bet you're right!. I think it is a combination of the dimensional equation following quantum froth!.Www@QuestionHome@Com

wtf u talkin bout!?Www@QuestionHome@Com

I'm sure there's a term for the belief that philosophy can not be properly done in a vacuum, but must be informed by our knowledge!. I don't know what that term is, but your question would be a good example of it!.

Granted, your question is a "what if" so of course it's hypothetical, but if there's something in your scenario which doesn't accord with reality, then it will always be just a hypothetical!. And if a scenario will always be hypothetical, with NO chance of it ever happening (due to it not "jiving" with reality), then one must question the usefulness of asking such a question!.

In your case, I happen to know a bit about cosmology, and I need to make the correction that black holes do not operate in the manner you've described!. They are not cosmic vacuum cleaners, and gravity works exactly the same for them as for any other object with mass!. For example, if the sun were for some reason to implode into a black hole tomorrow, the only difference it would make on Earth is that we would no longer receive any light or heat from it!. It wouldn't suck in any planets, even close-by Mercury, in fact all the planets would continue in their orbits exactly as before!. At the center of our own Milky Way galaxy there's a black hole with millions or even billions of times more mass than our star, the sun!. But even such a big monster-sized black hole can only consume matter that falls into it; it can't "suck in" distant stars!. (Lucky for us!)

also, black holes can't get "over-compressed" and explode, because for it to explode, the explosion would have to be stronger than the gravity, and that just ain't gonna happen!. The gravity of a black hole will always be greater than any internal pressure, because any matter that falls into a black hole just gets added to its mass (and hence its gravity)!. So there's actually no limit to how much matter a black hole can consume; if you feed it an infinite amount of matter, it'll eat it all up and ask for seconds!. :-)

Finally, observations in the past couple decades have shown that galaxies are in motion away from each other, but are actually speeding up, not slowing down!. Not only is our universe continuing to expand, but the expansion is accelerating!.

My point to all this isn't just to educate you a bit about astronomy, but also to say that philosophical thought alone is not enough to answer every question!. Sometimes we need the knowledge and insights that come from science and from observing the world around us!. This will not only let us be better informed and better able to answer the question, but perhaps more importantly we'll be in a better position to know what the right question to ask should be!.
