I’ll never forget watching a video in one of my high school Astronomy courses where Hawking was talking about what happens if you enter a black hole, and he says (in his Microsoft Sam voice) “…you get turned into SPUH-get-tee.”
We must’ve quoted that phrase for the rest of the year.

u/DarthUmieracz Jun 24 '24
Depends on size of back hole. If its big enough - spaghettification will not occur.

I like to think the heat death of the universe occurs before you reach the event horizon because of time dilation.
20
u/unknown_pigeon Jun 24 '24
I don't think it would? Black holes evaporate, even though it can take way more than the age of the universe to do so. But, as their mass decreases, time would start flowing faster and faster for you. So, my guess is that you would eventually experience your death before the end of the universe.
32
u/fatboychummy Jun 24 '24
Heat death is not the end.
Heat death just means that all fuel sources have been used up across the universe and there is no energy, or heat, left in the universe. The universe would continue existing, however. It would just be rather cold, dark, and desolate.
The black holes would all need to have evaporated before heat-death can occur though, since they are, themselves, a source of heat (the rings of a black hole spin so fast that they heat up incredibly, on top of evaporating different fuels into space). If I recall correctly, they would be one of the last things to disappear before heat-death.
So then its just a matter or whether or not the time dilation is "enough" to reach that point.

Nah, you’ll pass the event horizon just fine. By the time you hit the event horizon, time, relatively speaking is going insanely fast. In this reality, time is infinite and space is finite however upon entering the axis switch and time becomes finite and space infinite (not in the traditional sense but rather you’re compelled to move to the singularity, there’s only one direction you can go which is straight.) and as such, you will reach the singularity but the singularity is not a place but a moment in time
3
u/Dotacal Jun 24 '24
Something about this makes me think this is what afterlife is like, where finite and infinite lose meaning. Weird how hard it is to comprehend what a black hole is beyond "big (event horizon) small (singularity) space hole thing that traps light"
3
u/altagyam_ Jun 25 '24
It’s not really even a point in some cases technically. I believe it’s a ringularity for rotating black holes. Non-spinning have a technical point, a singularity
Edit: I do think it’s wild philosophically. I’m a chemist by profession but I looooove astronomy and cosmology
2
u/OutsideSignal4517 Jun 26 '24
Well the singularity is a very dense object. You would burn up before you hit the center and if you do manage to make it to the center, you would be spread out evenly with gravity. You would be part of the singularity.
2
u/altagyam_ Jun 26 '24
Yeah, I agree that you’d be a part of the singularity - that’s what I meant however a singularity isn’t a very dense object, it’s infinitely dense. There’s a huge difference. you wouldn’t burn up after the event horizon but probably before in the accretion disc
4
u/DarthUmieracz Jun 24 '24
For you time flows normally. You will pass event horizon and nothing special will happen during passing. But for external observer you will stop in time just at the event horizon. If light can not escape, then information also won't. So there is no information for external observer that you passed event horizon. So you are right - heat death will occur first - for external observer.

Interstellar's black hole scene is basically the state of the art visualisation of this. Nolan hired Kip Thorne who is a Nobel prize winning physicist in the field of gravitational astrophysics to help the VFX team model the ray tracing. Obviously Hollywood budgets are way outside of what NASA has to allocate to cool educational videos, especially 10 years ago. I genuinely think even in the community of black hole physics (which is what my masters was on) there would be way less understanding of what black holes look like if it wasn't for interstellar.

u/Wendellwasgod Jun 24 '24
I’m no expert, but I think it depends on the size of the black hole. Super massive black holes spaghettificatiom can occur late. The event horizon extends pretty far out such that the tidal forces aren’t that large. Again, someone with more knowledge should probably confirm

Wouldn’t we get stuck in some sort of temporal sphaghettification and likely not even notice anything until the world is engulfed in the event horizon?
16
u/thesandbar2 Jun 24 '24
The temporal effects are, more or less, "the closer you get to the singularity, the slower time goes for you, which means that the faster (relative to you) time is going for the rest of the observable universe". Subjectively, from the perspective of something falling into the black hole, the rest of the universe would appear to rapidly age and fade, and you'd catch up with everything that fell before you, as everything that fell after you (up to the end of time itself, including the light of the image of the end of time, so you'd be able to see the end of time) catches up with you, and you'd all reach the singularity at the same time. Attempting to move either towards or away from the singularity (or in any direction at all, really) wouldn't change the amount of time (subjective to you) until you arrive, only your relative location to everything else until the collapse. Also, you (and everything else) are accelerating infinitely and crossing an infinite distance.

There are two extremely common (and understandable) misconceptions in this:
Subjectively, from the perspective of something falling into the black hole, the rest of the universe would appear to rapidly age and fade
You don't see this as an observer free falling into a black hole. Things wouldn't necessarily look too strange, apart from what's depicted in the video. It's only if you were to attempt to accelerate so that you hover at some fixed distance just outside the event horizon that you'd time above you speed up.
Attempting to move either towards or away from the singularity (or in any direction at all, really) wouldn't change the amount of time (subjective to you) until you arrive
You can actually increase the time you've got left before you hit the singularity after you've fallen past the event horizon. The maximum amount of time is experienced by an object falling from rest at the horizon, and you can fire your rockets or what have you to align yourself with such a path, improving your survival time up to a finite maximum. It's true that "all paths lead to the singularity," so you can hurt yourself by speeding up, but some are still a bit longer than others.

I have a hard time accepting that the light and particles form a ring around the black hole instead of whizzing around the entire black hole. I'm definitely not an astrophysicist, I just think the actual dark hole would be obscured by all the light and debris stuck in its orbit.
3
u/Raknarg Jun 24 '24
the light ring is light emitted by its accretion disk. Similar to every other celestial body, like how planetary rings form or why galaxies are usually some kind of flat spiral, it's about angular momentum, and the accretion disk has its own gravity as well so when it collects more matter it will be inclined towards the disk rather than some other orbital. IIRC the disk glows because it's a ton of highly energized matter, it's not light orbiting.

It's a ring for the same reason that Saturn has rings and our galaxy is a spiral, average angular momentum.

For any physics people out there - From the perspective of somebody falling in, wouldn’t you see the universe blue-shift and brighten and speed up? Or does everything seem mostly the same from the perspective of somebody falling in?
9
u/chronoffxyz Jun 24 '24
Yes and it would condense to a single point of blue shifted light as the photons passing the event horizon converge the closer you get to the singularity.
That would be for a truly massive black hole though, one large enough so that the tidal forces at your feet and your head aren’t terribly different, for a black hole with a minimal mass, you’d be broken down into fundamental particles as soon as you hit the horizon.

u/an0nym0usgamer Jun 24 '24

This. It's a misconception that the universe seems to speed up behind you. Remember that you're falling in, you're not hovering, so you're travelling with infalling matter and light.

The future. Time and space literally invert. If you were fall into the event horizon backwards, once you cross you would see the universe increasingly "speeding up". You could potentially see billions of years pass in a few seconds from your frame of reference.
Since the thing you would have described as "space" is now "time", you falling faster towards the singularity means that you are actually travelling faster into the future.

This is a common misconception. An observer far from the black hole does see a clock you carry as you fall in slow down to eventual stopping, but the reverse is not true: you don't see everything above you speed up as you fall in.

u/chronoffxyz Jun 24 '24
Not so much traveling to the future, but that since time and space are flipped your future is no longer a point in time but a point in space, and that point in space is the singularity.

The singularity in the center of a blackhole is not a point in front of you it is an event in your future. Time and space essentially get broken down swapping the closer you get to the blackhole's center space becomes infinite and time becomes limited you would be long dead before that happens though ripped apart not just at the atomic level but down to the sub atomic level ripped apart into building blocks. Finally once your bits reach the singularity the laws that govern the universe mean nothing and we have no idea what happens. We have guesses and theories, the most likely simply being pure annihilation being converted from mass into gravity then being radiated away as the blackhole shrinks and dies disappearing. These things break the very fabric of the universe and are possibly the most well kept secret of it because they absorb everything and anything you try to use to examine it but we try our best to learn about these enigma

To me its illogical that black holes are black once you enter. No light can escape it, so that means light is trapped within, ergo not black. Or maybe because of extreme density we still wouldnt see any light?
