Just because you don't like the fact that black holes may violate the 3rd law (I don't believe they do), doesn't mean you have to break the other 3 to make it so.

FTA: As a dying star collapses under its own gravity, it's surrounded by a boundary called the event horizon: the point of no return, past which nothing can escape the black hole's gravity. The star will continue to shrink, but eventually it will reach a stage where it can't get any smaller because the loops cannot compress anymore.

At this point, the loops exert an outward pressure called "quantum bounce," which transforms the black hole into a white hole. According to the team's rough estimates, it takes just a few thousandths of a second for a black hole to transform into a white hole.


Waitwaitwait. Lemme see if I understand this... THEORETICALLY, a black hole can only absorb and contain so much matter and energy. Eventually, it would, basically, burst, expelling said matter and energy back into the universe in an instant.

... With a bang...

... And if a big enough black hole could absorb enough matter and energy, and suddenly underwent this "quantum bounce", it would produce...

A BIG bang...

Okay, a black hole is formed when a massive star goes supernova, right? All that's left is the innermost core of that star and a MASSIVE gravity well that sucks in EVERYTHING around it, including light.

What the theory in this article states, is that the star core will keep getting compressed as the gravity well keeps growing, like a balloon in reverse. Eventually, after billions or trillions of years, the core gets compressed until it can't shrink any further and... pops. This results in an atomic explosion beyond biblical proportions, and all that energy and matter sucked into the black hole is expelled at the speed of light!

This... this could be how the "Big Bang" happened. O_O

After billions or trillions of apparent years, from TFA:

"At this point, the loops exert an outward pressure called "quantum bounce," which transforms the black hole into a white hole. According to the team's rough estimates, it takes just a few thousandths of a second for a black hole to transform into a white hole. Yet even though the transformation is nearly instantaneous, the researchers say, black holes can still appear to us as lasting billions or trillions of years because their gravity stretches light waves and dilates time."


So it collapses, then nearly immediately explodes, but having collapsed it creates a time dilation that causes external observers to see a slowed down version of it, so the black hole state persists to observers for long periods.

I'd be curious what the low end estimate for an external observations duration of this would be, if it's more than the current age of the universe then that explains why we haven't seen the phenomenon resolve itself yet.

So if the initial amount of material causes the bounce and it starts rebounding immediately, then what happens to all of the other material that we see falling to the event horizon after? Does that just accumulate or would it cause another bounce or compression that keeps this cycle going forever? Can this effect generate enough energy to overcome the mass of the black hole?

An explosion is matter moving and that won't happen in a gravity field strong enough to hold back light.

From the perspective of the hole there's likely very little difference between the initial material and the additional material.  If it's a few thousandths of a second for the hole to collapse and detonate from its perspective the rest of the material added is likely just stuff that was falling in but not necessary to start the initial bounce.

An explosion is matter moving and that won't happen in a gravity field strong enough to hold back light.


Think of the supernova's shock front as the initial ripple of a rain drop that is suddenly almost falling into a puddle or both falling in and escaping from the surface faster than the 'meandering walls' forces within the puddles molecules, where there is no observable lateral boundary to the puddle(as a superflat ocean that only has this one droplets interaction dispersed within the magnifying glass of focus) for the ripples to interact with, canceling them out. This way, you can think of a linear double-slit quantum effect without having a grandfather paradox or a wormhole doppelganger uncertainty clause.

Once that separation happens, there likely isn't a way to not already be under its gravitational effects within any region of its domination of gravity over matter. This is why I think that matter entering one acts as trillions of corks slowing the compression that is likely also a spatial relocation of the core, meaning if you ever were to be able to survive the magnetic induction furnace of an 'event horizon' to reach a holes absolute center, you will likely see the original star before its collapse so many dozens of lightyears away from where you encountered the original point of black hole phenomena, basically from that perspective the star's supernova is where it becomes super-Sonic-the-sprite-hedgehog and sprints to the most localized finish, before dragging you and every little grain of non-virtual matter it could snag, where the actual hole outside of your observation likely snags a red giant or brown dwarf that it uses to convert itself into a rapidly spinning neutron star when no one is looking, sometime after floating away from any clutchable matter for long enough to evaporate or warm up to a certain extent.
 
2014-07-22 05:09:47 PM  
So all of that was supposed to reply to your material question, that matter is like gasoline on a fire, and once the black hole boundary is defined then matter falling into it is simply preventing its even more rapid dissipation, likely preventing them from merging and shrinking the universe by speeding it up.
