I wish I could tell you more. It's really an unknown region. I can speculate, I guess... But first, read this story. It's fiction, but it gives you a good feel for the concepts.

The Planck Dive by Greg Egan

The interesting part of a black hole is that it is a hole in time just as much as space. Objects closer and closer to the black hole are subject to relative time dilation and space contraction then objects further away, as gravity is just like constant acceleration in our universe...

There are some applets and some math there too, in the other sections, that can help you start figuring out what happens mathematically around a black hole, and maybe you can start some of your own theories as how that applies to the real universe.

SWEET! [lol]

Hmm...I left this topic alone and look it explodes, heh

Well, why else would it explode,eh. Having chunk of anti-matter and matter is the most efficient form of energy conversion known to man. E=mc^2. Jeezs, Kraemahz I thought you of all people would have figured this out.

So Little Miss, were your questions answered?

Gee, thanks guys. especially armrha, I didn't read it yet, I will find time for that, it's just I have tones of books right now [lol] .

Infernity, the ^ symbol is called the caret (or circumflex), commonly used to denote power. 8.751248 x 10^29 means 8.751248 times ten to the twenty-ninth power. Another way to write powers is 8.751248E29, which I prefer (E means exponent in this case).

kraemahz,
Yeah, I figured this out already heh.
Hmm as far as I know 'E' also symbolize *energy*, at least in this familiar equation E=mc^2 ...

So Little Miss, were your questions answered?

Well , no actually, I was wondering about the unknown part...

I'll study the subject and make my own supposedly rational theory.

''How do we call EVERYTHING? I mean, beyond the universe, and multiverses and all the contains elements. Is there a name but "everything"? is "cosmos" the name, or is it just a synonym to "universe"?''

The name for Everything is the omniverse http://en.wikipedia.org/wiki/Omniverse .

[Infernity]

Oh gee thank you, I'll remember that
Heh weired I didn't think of it, Omni = all; everything (Latin origin)

Suppose a type 3 civilisation succeeds in creating a child universe and in getting some kind of probe into it. What is the probability that the child universe would have any kind of material or useful energy within it that the probe could eventually find and use to begin self replication processes? Also, would the physical constants of the child universe likely be friendly or hostile to the probe's efforts to reestablish life?

[Infernity]

Hmm interesting, well the temper of it would probably be balanced, um, well before I can end the sentence by answering the question, what's a type 3 civilisation? [huh]

To be continued.....

This is explained in the article http://prospectmagaz...ils.php?id=6701 mentioned at the very beginning of this thread. I should have said "type III civilisation" rather than "type 3 civilisation." No matter what it may be called, what really matters is that the civilisation is advanced enough to create a new universe and get a seeding probe into it.

[quadclops]

Maybe someone can explain, I'm unsure as to the purpose of the "baby universe."

Are we supposed to use it as a tool for salvaging this universe when the end draws near, or are we supposed to enter it and use it as a fresh new space-time to live in?

If the latter, I presume there will be a "Big Bang" effect taking place within the baby as it pops into existance. If we're inside it at this stage, how do we protect ourselves from the enormous heat and pressure during it's early inflationary period?

[Clifford Greenblatt]

The way the article described the use of a baby universe is to provide a fresh space-time to live in when the parent universe becomes uninhabitable. My major question concerns issues of statistical mechanics. Would you have to create so many baby universes before you find one that is inhabitable that you would need more energy to make them then is available in the parent universe?

[Infernity]

I think all this is so bloody far away we don't really should bother ourselves thinking of it...

If we already do, um well energy is not being invented as it is not being destroyed. I think we should find a way to recycle used energy. We are so poor, really. It all still exists, and it is all still energy...

Friendly or not? balanced. Advantages and disadvantages.

The problem with recycling used energy in a big freeze is that the mass/energy would be spread out over much too great of a distance to collect enough of it to be useful. However, your idea makes a great deal of sense before a big freeze. Do you know of any articles about cosmic energy conservation? I am not aware of any but maybe there are a number of them about which I am not aware. I would think that the technology for cosmic energy conservation would be much simpler than the technology for escaping to a new universe and it would put off the need to escape a big freeze for a huge amount of time.
