What is on the Other Side of a Black Hole?
Written by Fraser Cain
Question: What is on the other side of a black hole?
Answer: There is no other side.
Science fiction has populated the idea that a black hole serves a portal to another world. If you could pass through, where does a black hole go? Perhaps you'll come to some other dimension, or re-emerge from some other part of the Universe?
No, a black hole only leads to death, for you, your spaceship, and another else that's unlucky enough to fall in.
Imagine you fell into a star like our Sun, there would be no question what would happen to you. The intense heat, gravity and pressure would kill you. If you compress more than 5x the mass of the Sun into a tight little area, you get a black hole. But the gravity, heat and pressure are all still there, just much more intense.
If you actually fell into a black hole, the tidal forces pulling at you are so extreme that the force on your feet is dramatically stronger than the force at your head. You would be stretched out and torn into pieces, and then those pieces would be torn into pieces. You would eventually be pulled into a stream of atoms, winding their way down to the surface of the black hole. For this process, scientists have a technical term: spaghettification.
Let's say you could survive this journey. Where does the black hole lead? No where. All of the mass of the star that came before the black hole is still there, pulling at you with all its gravity. This intense gravity would tear every molecule apart, and all the atoms. Protons and electrons would be crushed together to create neutrons, and then these would be crushed together even further into some kind of exotic form of superdense matter.
It's even possible that the heart of a black hole is single point of infinitely small size, containing the mass of many stars. This black hole is not a portal to anywhere, it's just a final destination.
Here's an article I did about how to maximize your time while falling into a black hole.

A black hole singularity crushes everything out of existence even the history of what it was.
Singularities with turbulence may siphon energy into a null region and produce new Universes. Thus a natural cycle of singularities to singularities would be a part of our reality.

More interesting thing to ponder is what do you see when you fall into a black hole. Remember that the time slows down in huge gravity.

We are always looking for some magical transport to take us to some better place. A black hole is simply a place where gravity is so powerful that all space has been squeezed out of the location. Black holes are certainly amazing but surely they are no more a pathway to some other place or dimension than death is.

But aren't black holes formed around space and time? Yet is it possible for there to be wormholes within there? *Gets book*
Point A . . Point B
"In theory, wormholes could allow you to travel between any two points in either time or space. Normally, two points in the vastness of spacetime would be much too far apart to travel between.
Einstein thought that spacetime is curved. If thisis true, and most experts believe it is, the distance between the two points could be shorter than it seems. Shortcuts called wormholes would allow you to travel between the two points.Wormholes might exist in the heart of blackholes, but there's no way of finding out yet."
from the book Mysteries & Marvels of Science.

In Steve Hawkings "A brief history of Time" he sumarises black holes and gravity in laymen terms as follows :
Imagine a sheet stretched out tight, now consider that this sheet is four dimensional (space and time); this represents the space time continuum.
Now if you placed a marble on the sheet it would leave a very small indentation in which nearby less dense objects would fall into. If you placed a more dense object such as a bowling ball then the indentation in the sheet would allow more dense objects to fall into it and will also increase the distance an object needs to be in order to fall into it.
This can represent the difference between the gravatational pull between planets and stars.
Now if gravity really is like an indentation in the space time continuum then a black hole could be like something so dense that it rips a hole in the space time continuum. If this were true I still have no doubt that a black hole would cause death but the question would still remain "As tiny as it may be, what is through that hole?" Subspace?, another dimension?, a connecting white hole that spews matter back in to the universe?. Point is, we just don't know.

OR…
A theory is that we have a fluctuating universe, where a black hole(s) compress all matter in the universe to a infinitly small, infinitly dense point and we have the big bang again!
AND
If there was another side (i don't think there is)
a victim would DIE anyways, due to heat, pressure AND radiation
OR (yes once again)
they don't even exist!
its just dark mater/energy

I HATE SCIENCE, YOU WILL ALL DIE AND NOT GO TO HEAVAN!

we have not seen any black holes in our galaxy why ? because the sun is bigger than a back hole the sun uses its most powerful gravity to pus the black hole away if e dint have the sun the end of the universe will come
some scientists belive that every solar sytem has a sun as the heart so imagine how important it is if the sun goes boom black holes will come the universe will be destroyed and nothing will be left!

you would be like in another dimesnion

just to let you know the smallest black hole is 2 times the mass of the sun and the largest is a billion times the mass of the sun

ur all mental ppl, who gives a shit where a blackhole leads, no one gives a shit about it, seriously, so just live a normal live and stop worriyng about things lika that, play call for duty 4, 5 or somthing, screw science, NO ONE GIVES A RATS ASS
January 9th, 2009 at 3:35 pm
POPLE, no one cares where a god damn blk hole leads to….trust me, when you go to school, ask as many people as you can, the only htign they will say is " i rilly dont give a crap wrea blackhole lads to, and i dont care either….
January 13th, 2009 at 8:09 am
tiago, I expect your the same person who keeps posting on this comments list, so the only person here with no-life is you,and YOU obviously give a rats ass about science becuase otherwise you would not be on this website!

If there is so much gravity wouldn't any matter entering the black hole be converted to energy (E=mc^2)? So if we entered the black hole we would be converted to energy and if forced into a singularity could we then find ourselves in between the fabric of space-time ultimately creating another big bang (if we could survive the experience)?

The author apparently is trying to make a point, but it's a little more complicated than the scope of this article.
We actually don't know if there is another side, and perhaps never will. For our purposes, anything we can produce would be annihilated shortly after it passed the event horizon, yes, but to say that it's just 'gone' is an oversimplification. And it leads to a paradox.

This is an entertaining possiblity, and it has a neat picture. http://en.wikipedia.org/wiki/Wormhole
It is possible that when enough matter collapses into one place, it pushes out into another three dimensional universe, like a balloon. The initial explosion would create a very 'big bang'. Some theorize that our universe is an example of this phenomenon.

Wow thats pretty scary!!!
We dont know if the person who wrote this article
if he saying the truth because he havent go on it yet!!
We dont know maybe its a timemachine or it will give you an extraordinary power. You'll nver knew.
That will be so cool!!!!
So you want to know where black holes lead huh?
try going in it and you will know!! ^_^ lol

Sorry

I heard that on the other side of a black whole there is a White whole That puts The matter back to gether in a different point in the Universe.Like in a different gallaxy or Solar system

hey now, thing is we got all the answer bout the black holes that are million of miles away but yet can't cure the sick in our planet. Now my question is once in the black hole does one turn to gas then float away??

Actually, this article is incorrect. The general relativity equations predict that in a rapidly ROTATING black hole, the singularity is not a point, but is instead a ring (which has a radius dependent on the mass of the black hole and how fast it is spinning). There are trajectories that go through the center of this ring instead of getting sucked into the black hole's singularity (the ring itself). These trajectories end up emerging "somewhere" which is not part of the local spacetime that is outside of the black hole from the perspective of the vehicle which entered it. Just where that "somewhere" is is unclear — it might be somewhere else in the same universe (exiting out another rotating black hole, in a fashion similar to a wormhole?) or even in a different universe.
