I think you'll need to learn a lot more before you can make any meaningful progress on this.

I'm going to read Gravitation in order to refine my idea.

Are you mathematically prepared? The book is divided into two sets of chapters. Segment I chapters are for people with the lesser mathematical background and Segment II chapters are for people with more mathematical background.

There is a lot of stuff on tensors and wedge operators. I hope you are equipped to handle this material.

I don't believe that I'm completely prepared to understand Gravitation 100% but I'm excited to be pointed in the right direction. I plan on majoring in physics because the world absolutely astonishes me. I love learning about how things work and exactly why the universe is the way it is. Gravitation could take me 2 years to understand, or it could take me 20 years to understand (but it'll most likely be closer to the 20-year range though lol).
I don't have a professional background in physics yet but I probably spend the majority of my time learning about physics through reading books and using the internet.

The causes of gravitation are yet to be established but the effects of gravitation are well modeled by the General Theory of Relativity. Actually Newtonian gravitation is a good model on those regions of space-time where the gravitational field is weak.

Isaac Newton punted on the question of what causes gravitation. In the Scholium of the third book of Principia Mathematica he writes: I feign no hypothesis (in Latin of course). Which means his famous law of gravitation can be sued to calculate the force of gravity between two masses but it does not say why two masses pull on each other and why gravity only pulls and does not push.

What if a black hole is a universe in it's own region of space-time?

Think about it, matter gets slowed down once it starts to approach 186,000 miles/sec. In a black hole, matter, light, or anything else for that matter can never escape. If you imagine our universe as a black hole, it would kind of make sense as to why matter will never travel faster than light (and why light always travels at 186,000 km/sec). What if the escape velocity of our black hole/universe is (theoretically) 186,00.01 miles/sec... Technically, nothing will ever be able to reach that speed... EVER. Matter can get close, but then it'll just turn into energy. And energy always travels at the same speed. That added ".01" may not seem like a lot but any number would work as long as it was more than 186,000 miles/sec.

I've been working on trying to create an equation for this but this is what's been on my mind for the last few months.

That's a really good idea. I'm no physicist, but I'm obsessed with physics because it's so AMAZING!
Anyways, once I read a book on string theory with a chapter on black holes and it said that black holes are elementary particles--they're points, and the only properties they have are mass, spin and charge. The only difference is that black holes are WAY more massive.
I also read that black holes could be factories for other universes, and that they could pass on their black hole "DNA" to the next universe, so universes which are better at making black holes (the universe factories) would produce more like universes, and eventually you'd get a sort of Darwinian universe evolution thingy, which would be really cool.
There's also a variation that says that advanced civilization create universes similar to their own once they've progressed enough, so the universes best at creating advanced civilizations would be the most common--which would explain why our universe seems to be so "fine-tuned" for life.

There is not an iota of evidence to support what you wrote (above).

What you have written is pixels and speculation.

I'm quite aware that there's no evidence; it's just something interesting I read in a book. Also, considering the fact that this thread is about black holes being other universes, there's not going to be much evidence for anything put forth here, anyways.

I think that I've seen the documentary on string theory that you mentioned! Yeah, physics is AWESOME to think about. lol

What makes me think of the black hole theory is because most people accept the Big Bang theory as fact (well, until we learn more about string theory, supersymmetry and other equally fascinating concepts.) I hated thinking of our universe just suddenly expanding without any particular reason (excluding quantum fluctuations and stuff like that). But the idea that a region of spacetime could be infinitely small and infinitely dense just made me think "hey, they sounds like a black hole"... lol

I wish that I could just fast-forward time and find out the answers to everything about physics. But I guess that if I could do that, then I'd already have the majority of those questions answered. So in the meantime, I guess that I'll have to take the slow route and study physics. But even if my theory turns out to be severely incorrect, I can't wait to see the progress of mankind in another 50 years. Maybe someone can find a better way of detecting neutrinos within that time.

Black Holes are as real as rain. Unfortunately we have very little idea of what is going on in a black hole. If we send a probe into one, we will not get any signals out. For two reasons: the tidal gravitational forces (stretch and squeeze) will destroy the probe; and even if the probe could survive the signals will not get out to us.
