A couple questions right off the bat:
Is the universe finite or infinite?
Does the rate of expansion increase with distance?
I don't think the Big Crunch can be possible with an increasingly expanding universe, nor with a horn shaped model.
My tall stack of earths model depends on the possibility of the Big Crunch.
But the density is decreasing with the expansion, so gravity would have less and less of an affect.
Exacty the same as when you throw a ball into the air... "gravity" decreases as height is gained, but it doesn't necessarily allow the the ball to escape to infinity.
But the ball is slowing down as height is gained. If the expansion of the universe is increasing, then gravity wouldn't be able to "turn-it-around", like earthly gravity does to the ball. If it is the same as the ball, then the universe couldn't be increasingly expanding.
This is not an output of the model, but just conjecture.
yeah, do you mind? Sorry if you think your wasting your time. I appreciate the replies, though.
It also doesn't make a huge amount of sense given the nature of the singularity.
I don't know much about the nature of the singularity.
It is possible that quantum gravity could describe what you are imagining, but now there would be no south/north pole, but a thin "neck" connecting each "sphere"
When you say neck, it seems like it'd be more than one point. Why couldn't it be one point?, where the northernmost point of one sphere and the sothernmost point of the other are the same point, singularity. I realize that the closer you get to singularity the more flat the model becomes, and the harder it would be for this point to exist on both spheres, but I don't see that it can't be done.
