[quote](ISM) -- Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It's a theory that has been explored over the past few decades by a small group of physicists including myself.
Successful as it is, there are notable unsolved questions with the standard big bang theory, which suggests that the universe began as a seemingly impossible "singularity," an infinitely small point containing an infinitely high concentration of matter, expanding in size to what we observe today. The theory of inflation, a super-fast expansion of space proposed in recent decades, fills in many important details, such as why slight lumps in the concentration of matter in the early universe coalesced into large celestial bodies such as galaxies and clusters of galaxies.
But these theories leave major questions unresolved. For example: What started the big bang? What caused inflation to end? What is the source of the mysterious dark energy that is apparently causing the universe to speed up its expansion?
The idea that our universe is entirely contained within a black hole provides answers to these problems and many more. It eliminates the notion of physically impossible singularities in our universe. And it draws upon two central theories in physics.
Nikodem Poplawski displays a "tornado in a tube". The top bottle symbolizes a black hole, the connected necks represent a wormhole and the lower bottle symbolizes the growing universe on the just-formed other side of the wormhole.The first is general relativity, the modern theory of gravity. It describes the universe at the largest scales. Any event in the universe occurs as a point in space and time, or spacetime. A massive object such as the Sun distorts or "curves" spacetime, like a bowling ball sitting on a canvas. The Sun's gravitational dent alters the motion of Earth and the other planets orbiting it. The sun's pull of the planets appears to us as the force of gravity.
The second is quantum mechanics, which describes the universe at the smallest scales, such as the level of the atom. However, quantum mechanics and general relativity are currently separate theories; physicists have been striving to combine the two successfully into a single theory of "quantum gravity" to adequately describe important phenomena, including the behavior of subatomic particles in black holes.
A 1960s adaptation of general relativity, called the Einstein-Cartan-Sciama-Kibble theory of gravity, takes into account effects from quantum mechanics. It not only provides a step towards quantum gravity but also leads to an alternative picture of the universe. This variation of general relativity incorporates an important quantum property known as spin. Particles such as atoms and electrons possess spin, or the internal angular momentum that is analogous to a skater spinning on ice.
In this picture, spins in particles interact with spacetime and endow it with a property called "torsion." To understand torsion, imagine spacetime not as a two-dimensional canvas, but as a flexible, one-dimensional rod. Bending the rod corresponds to curving spacetime, and twisting the rod corresponds to spacetime torsion. If a rod is thin, you can bend it, but it's hard to see if it's twisted or not.
Spacetime torsion would only be significant, let alone noticeable, in the early universe or in black holes. In these extreme environments, spacetime torsion would manifest itself as a repulsive force that counters the attractive gravitational force coming from spacetime curvature. As in the standard version of general relativity, very massive stars end up collapsing into black holes: regions of space from which nothing, not even light, can escape.
Here is how torsion would play out in the beginning moments of our universe. Initially, the gravitational attraction from curved space would overcome torsion's repulsive forces, serving to collapse matter into smaller regions of space. But eventually torsion would become very strong and prevent matter from compressing into a point of infinite density; matter would reach a state of extremely large but finite density. As energy can be converted into mass, the immensely high gravitational energy in this extremely dense state would cause an intense production of particles, greatly increasing the mass inside the black hole.
The increasing numbers of particles with spin would result in higher levels of spacetime torsion. Therepulsive torsion would stop the collapse and would create a "big bounce" like a compressed beach ball that snaps outward. The rapid recoil after such a big bounce could be what has led to our expanding universe. The result of this recoil matches observations of the universe's shape, geometry, and distribution of mass.
In turn, the torsion mechanism suggests an astonishing scenario: every black hole would produce a new, baby universe inside. If that is true, then the first matter in our universe came from somewhere else. So our own universe could be the interior of a black hole existing in another universe. Just as we cannot see what is going on inside black holes in the cosmos, any observers in the parent universe could not see what is going on in ours.
The motion of matter through the black hole's boundary, called an "event horizon," would only happen in one direction, providing a direction of time that we perceive as moving forward. The arrow of time in our universe would therefore be inherited, through torsion, from the parent universe.
Torsion could also explain the observed imbalance between matter and antimatter in the universe. Because of torsion, matter would decay into familiar electrons and quarks, and antimatter would decay into "dark matter," a mysterious invisible form of matter that appears to account for a majority of matter in the universe.
Finally, torsion could be the source of "dark energy," a mysterious form of energy that permeates all of space and increases the rate of expansion of the universe. Geometry with torsion naturally produces a "cosmological constant," a sort of added-on outward force which is the simplest way to explain dark energy. Thus, the observed accelerating expansion of the universe may end up being the strongest evidence for torsion.
Torsion therefore provides a theoretical foundation for a scenario in which the interior of every black hole becomes a new universe. It also appears as a remedy to several major problems of current theory of gravity and cosmology. Physicists still need to combine the Einstein-Cartan-Sciama-Kibble theory fully with quantum mechanics into a quantum theory of gravity. While resolving some major questions, it raises new ones of its own. For example, what do we know about the parent universe and the black hole inside which our own universe resides? How many layers of parent universes would we have? How can we test that our universe lives in a black hole?
The last question can potentially be investigated: since all stars and thus black holes rotate, our universe would have inherited the parent black hole’s axis of rotation as a "preferred direction." There is some recently reported evidence from surveys of over 15,000 galaxies that in one hemisphere of the universe more spiral galaxies are "left-handed", or rotating clockwise, while in the other hemisphere more are "right-handed", or rotating counterclockwise. In any case, I believe that including torsion in geometry of spacetime is a right step towards a successful theory of cosmology.[/quote]

Oh, that's why our universe is expanding. It's eating stuff from another universe.
Wow, it's like we just keep feeling smaller and smaller the more we know.
What if we could make faster-than-light-speed-travel possible by jumping into one universe, then into ours?
This doesn't even have theory status, it's just a wild hypothesis. It's okay, those are cool, but don't get on your high horses over this.
A black hole is literally just a remnant of a star with a massive gravitation field, how can it house a universe?
It's not a wormhole or anything in any way so uh, how?
Studying a bit of geophysics atm.

According to string theory -- the most widely accepted theory of everything to date, and the only credible theory that can tie both relativity and quantum mechanics -- there are in fact infinite alternate universes existing in (according to M-theory within string theory) an 11 dimensional multiverse. How small does that make you feel?

Because most older black holes house a lot more than just the remnant of a star.

It's so massive it may bend space to the extent it 'rips', put plainly. There are a few different ideas put in place regarding black holes and wormholes. The hypothetical [URL="http://www.krioma.net/articles/Bridge%20Theory/Einstein%20Rosen%20Bridge.htm"]Einstein-Rosen bridge[/URL] for instance. Of course all speculation, but nonetheless believed by a large fraction of scientists.
There's only one way to find out and that's to fly right into another black hole.
So that's why space is black :downs:
Sooo if we're inside a black hole, then does it emit hawking radiation? And if so, where does it come from?
"We are made of black hole stuff."
But the thing is, the gravitational pull is so strong, that things get ripped in halves then thirds and so on, waaay before it reaches the black hole itself. which makes the idea of a universe inside there meaningless.
That'd mean there's black holes inside all black holes right?
:psyduck:

Defense mechanism to prevent trans-universal invasions.

I could see this ironically enough making sense if there actually was a higher race controlling us.
Just a funny though, don't take this seriously.
Oh I bet there is a universe in every black hole. Depends on how far you go into it! :quagmire:

Yeah, doesn't really personally make sense to me.
A universe in every atom would, however. That, or atoms are universes. or Universe makes another universe. I think this idea IMHO is very very peaceful to think about, no matter how deep you go, you'll always find a universe.
[QUOTE=Novangel;36194347]It's not a wormhole or anything in any way so uh, how?[/QUOTE]
It can be.
A black hole is definitely more than just a remnant of a star with a large gravitational field.
It may be unrelated to the subject in a way because I skimmed it, but with the infinite possiblities of shit around the universe, we most likely could be. I believe everything big is just a small version of something bigger, so our universe could be so small, were just in the middle of one no matter what you could say. Cause I ain't no scientist or anything, but I'm pretty sure black holes don't have a size limit, so say, with the infinite amount of things in the universe, we could just be a universe inside a blackhole inside a universe inside a blackhole etc. Some say that the universe has a certain amount of matter and itll all die one day but I say bullshit. it all had to come from somewhere and that means more matter is being made, everywhere. but thats the only way i could think of the possiblity of a black hole surrounding us. It all confuses the shit out of me. gonna read it again lol
edit: How do we see blackholes if light cant escape? I think our eyes work by bringing in light waves then our eyes put it together as an image, so wouldnt it fuck with you if you looked at one? I know we have technology that captures things that aren't light to know what something is but how do we know what blackholes actually do?
edit: maybe with that infinite universe and black hole theory i have is like the reason why we wouldnt see the fucking HUGE things that would be within another universe thats not ours... the black hole lets no light escape therefor we cant see outside of it. could explain the whole space being black thing. so instead of seeing nothing, we just cant see past it because thats where light stops.
I need to stop thinking I'm stupid and theres probably so many things to prove what i said wrong lol

Sounds like wormholes dude, and we're pretty sure that they're either totally impossible or exist purely at the quantum scale.

A black hole is a universe "Steam bubble" being created. In the vastness of empty nothingness (which may act as a whole other "Measure of space") The steam bubbles that are the black holes are infact either soon to be good dimensions or will eventually collapse.
If something gets sucked into the "dimension" What happens is unknown. It may appear in the other dimension or just cease to exist.
Black holes may be dimensional threat one day when they become a stable enough universe to rival our own and infact impact it on a glactic scale.
This is the reason a black hole may be created in the LHC, because a reality is created, whether that reality clicks and stabalizes/grows or not decides if a black hole is formed or not, Chances are it will collapse but black holes have occoured inside our own "reality". It's rolling the dice[/quote]
QED
Around 3 weeks again i watched a dutch sort-of docu about the universe and how it works and how big it is, i was totally amazed and couldn't believe how small we actually are, compared to all those huge things
"We are just one of the many"
i can't believe there are still people who say : "There is no such thing as aliens"
>_<
Space, stop being so fuckhuge.

M-Theory is just a wild hypothesis.
This black whole theory is as credible as M-Theory, considering neither have been completed.

Wasn't this the idea of the teleportation theory in the Half-Life universe? They use Xen as interdimensional slingshot to travel somewhere instantly.

M-theory isn't just a wild hypothesis though
