How do scientists know what happens to you in a black hole?

Question

i mean, is it possible to survive, in it for like a day even. i don't know much about it, but if no one has been in it, how do they know what is goiing on in the black hole to begin with? yes its a dumb question.

Answer 1

They speculate at what will happen. Nobody really knows, so they make an educated guess.

Answer 2

A black hole is caused by a neutron star's collapse into itself by the sheer force of gravity, the center of that collapse being what is referred to as a "cloaked singularity." Because it is "cloaked" we cannot, even in theory, see what happens inside because the laws of relativity break down at that point by yielding infinities in the equations. But before relativity theory breaks down, it can predict the gravitational forces pulling at you from right before you cross the event horizon (the point of no return), to what happens after you are drawn inside the black down towards the singularity. Using Einstein's equations, you can show that the part of you that has crossed the event horizon will be gravitationally stretched more than the part that hasn't crossed yet. Once inside a black hole, the magnitues of gravitational force are exponential. I simple terms, you would be stretched into a strand of spaghetti. Time, at some point, will also stop for you completely, if you weren't already dead. It is not possible to survive even near a neutron star, the gravity is IMMENSE. Billions and billions of times stronger than here on Earth. Once you cross the event horizon of a black hole, which is the result of atomic nuclei being gravitationally squished out of three-dimensional existence, no atomic structure in the universe could withstand that kind of pressure.

Answer 3

Application of well understood physical principles and the mathematics of gravitation to a good imagination.

We understand what happens to you in a black hole despite never having sent someone into one for the same reason that we understand what happens to a ball thrown in the air at a particular velocity. We have equations that describe the physics of such events very accurately. The point at which the current equations no longer fully describe the universe is long past the point at which your body would be torn to pieces by acceleration.

Answer 4

If you know the properties of a place, you can "surmise" the conditions that would exist.

Same way you would know to bring Sunblock to a tropical beach even if you've never been there...

Other words used to describe what you're asking would be "extrapolation" and "intuition..."

We currently do not have sufficient technology to build a spaceship that could withstand the crushing gravitational pressure of a Black Hole...Any man-made ship would be smashed flatter than a piece of paper before it could even get close enough to investigate the conditions there...

Answer 5

Having never really been to a black hole, scientist do not KNOW for sure. But I am thinking you would be squished to pulp before you were able to enjoy the ride.

Answer 6

whether black holes have a acceptance for rapacity, gadgets that bypass by way of them at a "risk-free" distance are deflected in lots an identical way that they may well be by way of an consumer-friendly enormous call, and might proceed on their merry way. yet gadgets of any composition by any ability that get too close—closer than what has been termed the black hollow's journey horizon—are doomed: they are going to be drawn inexorably in direction of the midsection of the black hollow and undertaking to an ever increasing and finally damaging gravitational stress. to illustrate, in case you dropped ft first throughout the time of the form horizon, as you approached the black hollow's midsection you may result getting progressively greater uncomfortable. The gravitational stress of the black hollow might strengthen so dramatically that its pull on your ft may well be lots better than its pull on your head (for the reason that in a ft-first fall your ft are constantly somewhat closer than your head to the black hollow's midsection); lots better, in actuality, which you would be stretched with a stress that would as we communicate tear your physique to shreds.

Answer 7

It is called a theory. It is a prediction of what will happen based on what they know about black holes at this time.

Answer 8

depends on your point of view..
if you went into a black hole.. you would die pretty fast.
the gravity would tear you apart..
but from those on earth.. you wouldn't die for several eons
maybe even outlive the earth itself

but to answer your question.. its just the math and knowledge of sciences behind mass and energy

Answer 9

beats me
