(Big Think)   There's a theory that every black hole that forms gives rise to a baby Universe inside it. Could that be where our Universe came from, too?   (bigthink.com) divider line

Big think indeed, I really enjoyed this article
Thank you Subby 👍

I saw a black hole making a baby universe and the baby said hi to me and was making its own baby universe

As the Universe blows apart faster and faster thanks to Negative Energy, at some point there will be regions that bump up against the speed of light. Where that limit is exceeded: That's where new Universes are created.

Are we living in a baby universe that looks like a black hole to outsiders?

Never really thought about it but, can you pass that blunt?

I had this idea several years ago. Can someone nominate me for a Nobel now?

The only problem with it I see is how then do you explain Hawking radiation. (Someone else pointed that out in another black hole thread a few months ago.).

I first read about this 25 years ago, in a previous universe.

Do the black hole universes have black holes in them?

the generations of universes alternate between majority matter and antimatter.  This universe's black holes spit out a majority of matter from the spontaneous matter/antimatter pairs.  The antimatter drops into the black hole.

If Hawking radiation is real, then the mass of black holes is eventually freed and the singularity dissolves.  If you believe there's no such thing as a free lunch, that would seem to indicate black holes are NOT spawning new universes.

That could be where accelerating cosmic expansion and the big rip happens, internally. Not saying that's how it is. But it's an interesting idea.

Well, that's the thing about black holes and multiverse theories. Everybody's got one, and they all stink.
 
2022-01-27 4:23:31 PM  
My first thought when Hubbell suggested that instead of slowing down the expansion was actually speeding up was "perhaps" we were being sucked into a giant black hole in a bigger Universe.  One thing I've learned over the years is my first thought isn't worth much.

I have no idea what's going on and the older I get the less I care except that there are beers for lunch on Friday lunch, football games this weekend and the potential for trump to be in jail in a year or two.

Space is big, infinitely big, and small, infinitely small; go big go small it ends up in the same place.

Nope.  I love theoretical physics as much as the next person...but I make a good amount of money betting against my friends who discover the "New discovery in theoretical physics" about whether or not it is borne out by facts.

It's fun to dream, though.

Takes infinite energy to break the speed of light, right?

As I understand it, the Dark Energy expansion curve is at least second order, so it does nothing but increase. When it "hits the breaks" (hits light speed) that provides the energy to kick up another universe. And the whole thing rinses and repeats in a sort of foamy mess where ever these voids form creating new universes.

Again, this is just a dream I have. Just sort of an interesting toy to mess around with.

Black Hole is eating a star. Earth offers her some trees. She likes them and wants more. Earth shows her trees are her pit hair, ha ha. Black Hole DGAF and monches Earth's pits, arousing her.

Energy expanding spacetime is different than energy used to accelerate matter. One is something like a rising tide, the other is like a boat propeller.

And point of detail, it takes infinite energy to REACH the speed of light. Breaking it? Ummmm ... not yet, maybe not ever.

The trick is to move spacetime itself. You can't run 600 mph.  But you can on an airplane.  All you need is a big ol black hole, some spacetime, and lot of timey wimey wibbly wobbly stuff can happen.

If expanding spacetime is expanding; against what does it expand? The space time around it? My cartoon-like understanding of astrophysics informs me that Negative Energy would blow apart all matter in the final hours of the universe as the protons decay (or get blown apart. Both are good. Point is: No big crunch.).

I suppose Negative Energy's acceleration curve could flatten out as it approaches the speed of light. But that's no fun. I like to think (ok, pretend) it hits the wall and the energy driving it creates a new universe. But what do I know.

I like negative energy. It creates so many more new problems than it solves.

No.  As the already infinite universe expands infinitely, more space is added, "vacuum energy" remains the same and light just has further to travel.  And rules apply to things *in* the universe but are meaningless when applied to the bounds of the universe itself and beyond.

Time slows as you approach a black hole, so it is "perfectly plausible" that you could extend your civilization by tucking it into a black hole, hopefully to get out of it. It is a trick you would only want to try once.

It might also be useful to escape a BIG RIP scenario, where you move into a black hole JUST BEFORE the molecules inside you disintegrate. While the whole universe is ripping itself to pieces in seconds, you can stretch time out so that you can live billions of years in a nanosecond.

I am not doing the math. I am an Isaac Arthur minion. I will just kind of nod and say "Wow... or maybe..."

I will have no say in the matter anyway, unless I am a simulation of some bored superbeing a trillion years into the future. In which case I will say, in a Leonard Nimoy voice..... "let there be light!"
