The bigger thing I wonder. Is how much Mass it Requires for a Black Hole to Start Fusing Iron and Basicly Explode. Its also somehow Strange to Assume Time Stops. Because most of the Gravitational Effect of Time does not really require an Explanation that would assume Time Stops. What Stops is the Progress of Energy. A Black Hole so Massive it can Curve Light. Will have a Similar Effect on all Energy. Meaning that any Energy Affected by it will be Pulled towards the Black Hole and Potentially Slowed down by the Pull of that Black Hole. But this does not Change my Concept of Time. Because Time is still Time. Time is from the get go a Man Made Scale and not something the Universe Cares about. And the Fact that we cannot Build a Clock that would be able to keep moving at an Undaunted Speed inside a Gravitational Pull like that is not Surprising to me.

Phil: Thanks for the incredible ride! Just two things I might (or might not) add: 1. Tidal "spaghettification" is just as much about transverse compression as it is about longitudinal stretching. 2. An alternative, and perhaps even neater way to explain the inability of anything escaping from inside the event horizon, is that while outside it, the radial direction is spatial, inside it, the radial direction is time! And forward in time points toward the central singularity. So escaping from inside, is exactly the same as traveling backward in time!

The real reason why you can't escape the inside of a black hole (assuming classical GR which is mind blowing enough) isn't just because you can't "get out fast enough", it is because you literally are in the infinite future, and from your perspective every event in the outside universe has essentially already happened, and you only need to move in space to get it in your past light cone. Getting out would be equivalent to traveling back in time.

+Roy Bellafire Letss assume for a moment tat the person is capable of surviving those conditions. Does that mean the person would have experienced all of time except because of hawking radiation, he does so only till the point the black hole itself is extinguished. And if the person can remain wholly intact through all of it, then basically what he has done is time travel? Because his own state is stuck in what he entered the black hole with, and yet time in the rest of universe has passed faster. You were all the while disconnected out of "universe time", watching it pass by in fast forward (or perhaps it was fast forward till you hit the event horizon and then it happened within a moment?). And then when the black hole goes poof, you are plugged right back into it. Conversely if someone managed to create a space with absolutely zero gravitational effect, then for a person in that space, time would speed up. The person would spend time till say a certain point in HIS future and yet when he is plugged back into the universe time (gravitation restored to normal), the universe is practically stuck in the same point of time which has now become a part of his past (but still the present for the universe). So in this case, he has effectively travelled back to the past (his past) by first travelling to the future and then rejoining a region of space stuck at the same past point of time. How is that for a mindfuck?

The study of Black Holes grabbed my attention in elementary... To think a person is actually time traveling(into the future) when they get near a Black Hole(because that person time is slowing down). Also, if a person curiosity is so strong they could sacrifice their life by falling into a Black Hole to possibly see the creation of our(or another) universe. I remember as a kid thinking if it was possible to make a camera-drone type device that can drop into a Black Hole and survive long enough to get to the Event Horizon. I hope something similar can be created in our life time...

One of the reasons why this is impossible is that the camera will, like Plait said, undergo spaghettification so it won't retain the same properties as the original camera. Even if it was in a super massive black hole, the main reason it won't be able to detect ANYTHING whatsoever is that the light itself of whatever is inside won't be able to reach the camera, the reason being the escape velocity of a black hole is higher than the speed of light. How light works is that it is reflected in a way so that we can perceive it, while a black hole completely absorbs it so nothing can be visible from inside or outside. Furthermore, the nearest black hole is way too far away for us to reach it anytime, meaning at least millions of years if us or even the Earth for that matter is still around. Whatever happens in a black hole, stays in a black hole (except for hawking radiation but that's a different subject).
@Alex-bw6yd6 жыл бұрын
Actually, the closer you get to the event horizon the stronger the effect on space-time it has. So hovering right above the event horizon time and space become essentially infinite. And so information trying to escape from that point would have to travel an infinite distance over an infinite amount of time. It would never be able to escape a warping of space-time like that. So you will never be able to receive information from inside or the very edge of the black hole, hence the reason it even has an edge.

PBS Space Time says that a person falling into a black hole will not see all of time pass by, only localized blue shifts (or something like that, I guess what I'm saying is that I dont understand this explanation). Can someone help me understand this? Seems like competing ideas. I know that black holes are by far, very mysterious and we have much to learn about them. I also know that scientists who study this stuff even have disputes about black hole properties. Is this one of those discrepancies? Help! I want to learn! (Also, I hope that this series never ends. I've enjoyed it so much and I hope there are many, many new episodes in the future.)

+vormov The difference is how simple things are. Here the simplest treatment is given; all of time. It's close enough to the truth. In reality when things start heading towards infinity there's usually some bug that pops up and ruins things. PBS Space Time is correct, there are two problems. First time seems to go faster and faster, eventually everything seems to happen at once so you can't 'see' a lot of it, it's a mess. Secondly the person is still falling, not standing still at the horizon so the incomming signals get warped by the black hole too.

Something I want to make sure I understand. What I was told as a child was, that a black hole combines all of its mass in a single point. After all we already agreed that no force in the universe can keep the core of a very large star from collapsing and it goes bye bye. So when it is said that a black hole grows with increasing size, we are primarily talking about the size of the space surrounding that former core matter that requires a higher escape velocity than the speed of light, yes? The actual size of whaterver matter is inside the black hole is probably unknown because we can't look inside. Do we have a concept for what state the matter inside the black hole could be in? Is it actually a single spot or can we maybe still apply the concept of having a radius to it?
@ddjoray10428 жыл бұрын
+ruolbu As I understand it, black holes have a volume of zero, therefore are infinitely dense (hence the infinitely downward spiraling gravity well image you often see associated with them), no matter what their mass is. The increase in mass accounts for an increase in the diameter of the event horizon. A black hole's singularity isn't a material object, it is simply a property of spacetime at a specific location, therefore the matter has no state of matter. If you know anything about 3D modelling, think of a black hole as a point in a 3D space that can hold metadata. The metadata is the mass, held as a generic object (not a string, integer, etc.).
@garethdean63828 жыл бұрын
+ruolbu The fact that our current theories predict infinities is good evidence they are incomplete. We've been here before (In the 1900s the 'ultraviolet catastrophe' predicted all warm objects must glow infinitely bright.) so it's likely that whatever is inside a black hole isn't infinite but does something weird that combines gravity and quantum mechanics. When we talk about the size of black holes, yes, we are usually talking about the 'event horizon'; a sphere of space that nothing can escape from.
@tiffles38908 жыл бұрын
+Idrialite I know of 3D modelling and that is one hell of a way to explain the concept that you are trying to convey. But I read somewhere that a lot of physicists argue that if something has exact zero volume, like what the math implies, then it effectively doesn't exist. If it doesn't exist it cannot exert gravity. So they say that there must be a limit at which the contraction stops even if it is minuscule.
@garethdean63828 жыл бұрын
Gaurab Chatterjee To me it seems rather like saying I can accelerate my car from 0-60 in 10 seconds so therefore I can accelerate it to the speed of light if I just step on the gas enough and nothing else intervenes. The math works out,but it ignores that quite a lot of things intervene. We get a singularity if a star core collapses and nothing else intervenes. I am confident that one day we will discover there *is* something else and it stops this zero volume kerfuffle.

Wait a second... if all of time went by in the universe, wouldn't that also mean the black hole itself would evaporate away due to hawking radiation, just as you were about to pass the event horizon? So falling into a gargantuan galaxy core black hole would essentially be a time machine to the end of time.
@calinculianu8 жыл бұрын
+UnknownXV Yes, I'm confused by this as well. Black holes *DO* eventually evaporate. If all of time goes by as you approach the horizon -- doesn't that mean that as you approach the horizon that the black hole would evaporate before you got there because *all* of time would go by? I'm confused as hell.
@UnknownXV8 жыл бұрын
Calin Culianu I mean, it should, right? As far as I know, black holes do evaporate through hawking radiation, though a giant one might take trillions of years. But so what? If all time passes by instantly, that's all of time. Or would it be all of time? Wouldn't it be all the time it takes for the black hole to evaporate away, at which point there is no more black hole and thus more more extreme spacetime distortion causing your time dialiation to occur in the first place?
@flaviusclaudius75108 жыл бұрын
+UnknownXV AFAIK, you only take an infinite amount of time if you're a massless particle trying to cross the event horizon. If you have mass, any object behind you would notice that the strength of gravity on a straight line connecting it and the singularity is stronger, deforming the event horizon. Note: I am not a cosmologist, I only did Honours in GR in undergrad, so please take this with a grain of salt. Also note that this doesn't take into account quantum mechanical effects, which are no doubt important at such a surface.
@UnknownXV8 жыл бұрын
Natasha Taylor So time dilation doesn't occur if you have mass?
@flaviusclaudius75108 жыл бұрын
The time dilation does occur, yes, but infinite time doesn't pass because you don't get infinitesimally close to the event horizon before being consumed by it (relative to an observer at infinity).

This is probably the most reasonable way the universe was formed to me. It explains why the universe is expanding and because of the time shift why we think all of matter being made at the start of the black hole forming even though it is being pulled in over a time.
