black holes and white bangs

Question for physicists: isn't a "white hole" really a "white bang"?

In the weird and wonderful world of physics, "white holes" are associated with black holes, which are said to have been 'observed' in 'reality'. The problem is that if white holes exist, they'd be bangs not holes.

A black hole is a region of spacetime where gravity is so strong that nothing can escape, not even light. No light = darkness = blackness. Hence "black" hole. Gravity is infinitely strong at the "singularity" at the heart of a black hole. So matter falling into a black hole is squashed -- becoming more and more dense until at the singularity, matter is infinitely dense.

The question is, what happens to all the matter and other stuff falling into a black hole?

There are many theories, including some to the effect that the stuff that gets sucked into a black hole in one universe explodes outward as a white hole in another. In other words that at the back of every black hole is a white hole (possibly with a wormhole/colon connecting the two).

Whether the theories are true or not is not the point (of this post). The point is that if black holes suck, then white holes blow. If black holes are implosions, white holes are explosions. A hole is the opposite of an explosion. So a white hole's really a white bang.

Consider what was supposedly the biggest explosion of all time: the big bang. Once upon no time, the theory goes, the universe was extremely hot and dense. Then, for reasons of which I am blissfully ignorant, exploded outward in a great big bang that continues to drive the expansion of the universe to this very day. But not necessarily forever.

At some point/time, where/when the force driving the expansion of the Universe is weaker than gravity, the expansion will stop then reverse; the expansion will become a contraction. And all the matter and other stuff in the Universe will be pulled together in a big crunch.

The culmination of a big crunch could be a singularity where matter is so dense that it rebels against the contraction by exploding outward in a big bang. Maybe the Life of the universe is measured in big bang / big crunch cycles. Which gives rise to such metaphors as the breathing in and out of the Cosmos. Or God's heartbeat, if you prefer.

But whether big bang theory is correct or not, in one sense is not critical to the metaphysics of the Universe. In some pantheistic models, the universe is an organism, alive and well and growing and learning. Whether that organism was born in a big bang -- or in a barn or someplace else by some other means -- doesn't prove or disprove the existence of that organism, the biggest person of all: Everything That Is (ETI).

Let's say big bang theory is NOT the correct explanation of how the universe came into being. Let's say that the steady state theory is correct. Or that the immaculate conception theory is correct. Or that turtle theory is correct. Doesn't matter. How the biggest person of all came to be born doesn't change the fact of the birth.

And maybe it wasn't a Big Bang but a Big Wank: divine masturbation

I like the idea of the Big Crunch, but I think the Big Rip is where the evidence is actually pointing lately.

Hi Adam, thanks for your comment. The Big Rip, ey? Is that part of M-theory or something, that it's not so much strings or superstrings, but membranes?
Which, when ripped, give rise to new universes? Or something? Or am I being too literal minded?

The attention accorded to the esoteric findings and wild musings of the physics wunderkind, and the large amounts of money spent on their futuristic projects, is as relevant as the prattle on "celebrities". It all destracts from drastic problems - and is meant to. People are starving and dying from lack of medical attention, not just in "undeveloped" loser countries but in those that defined themselves as the paragons of progress. Very basic science also suffices to show us that we do not have more than a few more decades to fiddle while the ecosphere collapses.

Sorry to go off on that sour tangent.

What the pundits now tell us is that a region above the the surface of a black hole may reflect, in a holographic way, what goes on under the surface, thus conserving information. Supposedly, this implies that (a) beyond the very edges of our expanding universe is a surface - a screen - reflecting in 2D everything existing here in 3D (b) there is scope for questioning "reality".

Hi mgeorge, thanks for your comments. No apology needed: I think tangential sourness is entirely an appropriate stance in this day and age. (though in terms of science investment I suppose i'd better not get you started on the Large Hadron Collider!)

Do you really think we have as long as decades?

Bang... Wank... call it what you will, it was most certainly ORGASMIC!

Black Holes, White Holes, Pink, Purple and Red Holes, Rabbit Holes, 18 Holes... it's a holesome yoniverse (holistically speaking) and I'm a holy man... please lemme outta here!!!!

masterymistery said...

HI Antares, thank for your highly and wholly amusing comment. It cheered me up enormously on an otherwise grey day. Don't be too hasty about leaving the yoniverse. The lingamverse has its own issues!

On the environment and the time left, I could could link to my Knol (in Google) titled "Climate and Consumption - Introduction", but it would be throwing more cold water on the situation.

BTW, belated thanks for your supportive review of "Evolution of Ideas" some time ago.

masterymistery said...

mgeorge, RE "evolution of ideas" I lost the URL and have been trying to find more of your writing ever since. I suppose I could have just asked you...

Anyway, "Climate and Consumption": excellent piece. I've got the URL in my favourites now. Great that in #3 you provide suggestions on what people can do to achieve a more sustainable lifestyle.

Thanks for your comments, and ongoing support of this blog.

Cheers, MM

You can google for it, though I notice the URL is now shorter.

On whether we have decades left, it may depend on (a) who is meant by "we" - at least several billion may not survive (b) the kind of brutish existence we are left with.

masterymistery said...

mgeorge, it may be that Hobbes comes into his own after all / at last, with "nasty, brutish and short"!.

And it will be up to the dregs to undreg themselves and over generations bring us back to the examination we are currenbtly failing. So that we can try again.
