Sooo.... a 4D bulkystar explodes (superdupernova) then collapses and creates our 3D universe and somehow (waves hand around) this is not the bigbang you're looking for?

Sounds like an even bigger bang than the one the first theory talked about.

Did someone mention turtles? I like turtles

The idea that black holes spawn new universes has been around for a while.  If you think about it black holes and the big bang are the only places you have singularities in nature so maybe they are the same thing seen from different view points.

The theory that time has more than one dimension is even more bizarre.

Would that mean that inside the black holes in our universe exist 2d universes? And if we could somehow travel to the 4d universe we could potentially find another black hole and travel to a different 3d universe, also does the 4d universe need to be a in a black hole of a 5d universe which is also in a black hole of a 6d universe and so on and such?

Travel in that 4th dimension of the higher universe would be our hyperdrive. Not that that is possible or anything.

So if I dive into a black hole, am I 2D when I come out?
 
2013-09-15 01:17:55 PM  
So basically the singularity in a black hole tears a hole through space-time.  The resulting rip becomes the big bang singularity of a brand new universe with the material being sucked out of ours seeding the new one.

Infinite recursion, infinite rebirth.  I think this just became my favorite theory of all time.

Yay! 1st geenlight.

Brain hurts too. Been trying to explain this to the gf all day.. I think I understand it even less.

The point is this nearly fits the current observations but not 100%. It does provide an interesting alternative and maybe some day a challenge to the standard inflationary theory. Too early to tell.

If you have more than three space dimension a planet's orbit around a star or the star's around a galaxy center cannot be made stable.  Of course it would collapse into a 4-dimensional black hole. Everything would fall in, not orbit.

Of course the 4D universe comes from the event horizon of a black hole in a 5D universe.

Question for all you scienticians: If this theory is correct, is matter still entering our universe from the 4D universe? Or does the 4D universe no longer exist, the black hole having absorbed all of the matter from the 4D universe and then causing our Big Bang?

This theory is utterly ridiculous. There aren't even stable orbits in 4D, so to expect star lifecycles and black holes to be the same is just stupid, lasy thinking.

This so-called "science" is almost as ridiculous as catastrophic anthropogenic climate change "theory".

It's actually much less than 4D; closer to 22D/7, about the circumference of a turtle divided by its diameter.

One of the bizarre techniques in quantum field theory is working in fractional dimensions then taking the limit as dimensionality approaches 1+3. Some equations blow up when there are exactly 1+3 dimensions. They have a well defined limit as they approach that point.

You idiot, there is nothing weird about that. The sinc functions (sinx/x) blows up at zero (as you so pop-scienceily put it) but has a well-defined limit approaching zero and that is used as the value in practice. Nothing weird at all when dealing with real numbers.

Maybe you should learn a little more before you go around shouting about what is "weird" on discussion forums such as this.

So it's the 'Big Crunch' theory for the 4D bulkyverse? That would imply we are also heading for a big crunch which will result in a 2D universe which in turn will crunch and create a 1D 'verse which will crunch and... then what? I would not expect to find the 'verse to be that linear

In that case, I'm going for 0D turtles based on the supposition that imperfect measurement in any dimension renders the term meaningless for any given sample. D only becomes meaningful over many samples and then it tends to converge to 3 in this universe for most turtles.

All this does it push the question back a level: so where did the bulk universe come from? Also, it does NOT "avoid a singularity". You know where there are singularities, besides before the Big Bang? INSIDE BLACK HOLES.

Either this is one seriously stupid theory, or it's badly explained.
