Hi NormadaNare,
"I like your theory, it looks like you gave it some serious thought but, just a few questions. What would cause such a "finite bubble" if there are equal forces both at the center and outside the bubble? It seems very strange that if these forces can balance each other through the bubble, they shouldn't be able to balance themselves without the bubble."
Thank you. Well really it's a work in progress and questions regarding the theory in practices are helping me iron out the creases. Your questions are rather intelligent and requires me to do a lot of processing. I know very little about physics. I just found an interest in due to a discussion about the 'big bang' about a month ago. Since this, I have been studying physics intensely and, a recent conversation with a proffesor, who explained the inconsistancies of SR in regard to black holes, brought me to the conclusions of my theory.
Now with regard to bubbles this question is in regards to HOW it exists. Well I do not really know and another question you could have tacked on to this response is: If it is a bubble how is it expanding? because we all bubbles do not expand, right?
I will answer this question by explaining why a bubble MUST exist. Well there MUST be finite time to a finite spacetime, right? That would mean there would be a start and a finish. Just as a star implodes at the end of it's lifespan and our body dies at the end of ours. Then our finite universe must also have a lifespan. The 'big bang' theory can't explain how the universe is an extension of a previous finite spacetime. Whereby, if all that existed before the 'big bang' were finite gases, that, exploded to create our present universe, We must ask where did these gases come from? They would have a life span too, wouldn't they? So if everything is finite the neccesary consideration would be how would something that existed infinitely up to this point suddenly burnout: like a star imploding into infinite spacetime. Since the suggestion is that OUR finite spacetime is infinite, it thus goes beyond all logical reasoning. A possible explanation for this is that due to laws of conservation of energy and mass, this finite energy always existed so, when one form burnsout another form is created, adopting, the same energy that existed before. But this can be conclusively thrown out due to the fact, that, if everything we see existed in it's current state (in one form or another) infinitely, up to this point, how would a black hole exist? That is, we would already exist within an infinite space time i.e. our spacetime IS the infinite spacetime.
The fact that we are in a finite spacetime arising out of infinite spacetime (i.e. whatever is beyond these blackholes) is the only conclusion I can make.
As to how we could understand how this bubble exist:
The following equation measures the exact pressure required to create a bubble. Pi = the pressure within the bubble and Po = the pressure outside the bubble.
Pi - Po = 4T/r
I'm not quite sure how bubbles works, nor how infinite spacetime works. I need to do a fair bit of research here to understand this i.e. that is if I can ever understand it.
Your question gives rise to a lot of other feasible questions like;
How would the bubble expand as this is not nature as we know it to be?
How would infinite spacetime 'explode' into finite time?
What is contained in infinite spacetime?
What kind of qualities does infinite spacetime posess?
What kind of energies or forces would infinite spacetime posess?
I have not a clue at the present time.
"Also, my knowledge is limited on black holes so work with me; I was under the impression that black holes had specific mass that was very large but not infinite (otherwise we'd all be swallowed up), we just couldn't measure it because of the whole GR thing and the warping of space-time. This would also explain why black holes swallow each other sometimes."
Gravity of a black hole can be measured based on Newton' s Gravitational Constant. The distance from the centre of gravity where the gravity reaches an infinite force is the event horizon. (This is basically the radius where light infinitely red-shifts.)
Light speed being 3 000 000 000 000m/second cannot escape at this point and spacetime is bent infinitely. This is based on an accurate knowledge of the relationship that gravity has with the curvature of spacetime. There is a discrepancy with regard to the Lorentz transformation but, it so tiny that, noone can discredit the accuracy of this calculation. Between this point and the centre of gravity physicists are unaware of the qualities of this spacetime. If an object is 'sucked' into this BH the mass increases therefore the event horizon is also larger. Gravity should therefore also increase. But all it really does is create a larger space where spacetime is infinitely bent (if the blackhole 'sucked in' the whole universe it would become the size of the external 'bubble', thus, returning infinite spacetime back to it's original state). So we know at the event horizon gravity is a constant infinity and the force never increases at this point. This would be regardless of the BH's size.
With regards to your question, would we be sucked into this black hole if it posessed infinite gravity. I'll explain this:
Imagine if you were directly in the middle of two black holes, then, they would be applying equal pressure and neither could pull you in. If you moved, however, toward one black hole the force would slowly 'suck' you in. This is where my theory began.
If, however, our finite spacetime were encased within an infinite spacetime bubble, then forces would be pulling from all directions at all times which would make you static (i.e. sitting still). If the universe were expanding, on the other had, then all the planets and stars would be pulled apart relative to the expansion of the universe. I hope this makes sense.
"Lastly infinity is a very tricky concept because within it, one can basically say 1 = 2 and math goes all crazy. If this occurs, than all of physics as we know it goes wacky and the idea of balancing forces goes out the window, because just as infinity equals infinity, infinity doesn't equal infinity at the same time."
Well Cantor's concept of infinity defines different sized infinities. There are large ones and small ones, but infinity always equals infinity according to my thinking. You may be correct but I haven't really got that far in my studies.
Excellent questions.
