I haven't logged on to Totse for over a year, but I don't know where else I can ask this question and possibly get a serious answer. So, here is my question: If someone were to fall into a black hole's even horizon and survive in its point of singularity, could that person go back to a time before the black hole existed and escape?

Explanation of the mechanics of time plx

problem is there is no way to know/test this theory
but the major accepted theory is if someone were to fall into the pull of the singularity....while they were being what is called "spagettification" the idea is if they were to turn around and look out of the black hole back at the world they would see the entire fate of the universe in a matter of no time


but back to your question ...do you think you could survive being in a singularity about the size of a pea with about the same amount of density as all the planets in our solar system combined???????.......probly not....


hope i was a little help

No, you just die a terrible spagettification dead and eventually your energy will theoretically get radiated out over the course of a zillion years if hawking radiation does exist. Wormhole, multiverse theories maybe something else might happen. but a plain and simple black hole no.

The problem here is when you say If you could X. Since X doesn't mesh with known physics, then you can't make predictions using known physics.


Also, you can't time travel with black holes.

Cosmic strings yes.
Wormholes, yes.
Black holes, not really.

this, your initial statement about being able to survive inside the swartzchild radius is absurd.

They call it spaghettification in GR, it's just what it sounds like, once you slip a finger across that event horizon. SPAGHETTIFIED

"spaghettification" is due to the tidal forces between nearby points close to the black hole being so large, theres nothing special about the tidal forces inside the schwartzchild radius. If i remember correctly it was calculated that you could cross the event horizon of rotating supermassive black holes without being spaghettified.

Black hole wise you cannot travel backwards in time, probably. Fuck spaghettification, that's not the issue here.

According to Einstein the greater a gravitational field you are exposed to the slower time progresses for you or for any object for that matter.

here is a black hole event horizon ---> . ( Yes, it is almost magical.)
The closer you get to it the greater the force of gravity that is acting on you. Experiencing a greater force of gravity means that time progresses more slowly for you, so the closer you are to the event horizon the slower time proceeds for you.
Time: {earth normal time}----------{slow}{slower}{super slower} . <---black hole

Since time is going by very slowly for you near the black hole you are essentially travelling into the future because you are aging very slowly compared to your counterparts on earth.

The gravitational force at the eventhorizon probably does not reach infinity since that would mean that it would have sucked everything in the universe into it already i suppose. It probably though slows time down hella enough so that you could sit back and watch the end of the universe.

You are confusing the terms event horizon and singularity. The event horizon is simply the area around the black hole from which light (and so everything else) can not escape. According to GR the quantites used to predict the gravitational force at the singularity become infinite.

Your agument about being able to see the end of the universe comes back to spaghettification. To dilate time enough to compress millions of years outside the black hole into seconds of time as measured by you would probably require an enormous gravitational field. This could be found close to the singularity of smaller black holes but the tidal forces would be too large to avoid being torn apart. It would require an enomous black hole in order to get around the problem of spaghettification but still have a large enough mass to dilate time to that extent.

To put it simply (from a new book i got at xmas);

(something about supernova and black holes)..a singularity, a scrunched piece of the universe with almost no volume and infinite density. Surrounding the singularity is a boundary called the event horizon.(followed by something about the singularity being smaller then this . )

At the center of our galaxy they reckon theres a black hole with an event horizon 39 million km's wide....and it's(estimated) at 3 million times the mass of our sun.....wouldnt that mean theres no limit to the amount something can be compressed? Or is it simply converted, and spat out the ass of the black hole? Im under the theory matter cant be destroyed...

But what happens when the black hole finally runs out of food? Does it explode, or simply vanish? I guess we will never know eh?

Or(perhaps another idea...) the event horizon simply warp's light around the object, so instead of sucking it into nothingness it merely holds it in suspended animation, so to say. Then when the black holes gravity finally dies, everything is shot out at the fastest obtainable speed, thus ripping apart the fabric of time and collapsing the universe like a balloon.

Eventually when you compress matter enough you get a black hole. No one understands black holes on the quantum scale, or QCD in the enomously high density realm so i don't think anyone can really give an accurate answer for what actually happens to matter at the singularity. That is a question for quantum gravity. What is the ass of the black hole? In some sense the matter obviously stays within the black hole as the effect of its mass is still felt outside.

When black holes run out of food they just sit there dorment, maybe evaporating very slowly due to Hawking radiation.
