This shit really scare me.

What is the possibility that one comes close to our solar system?

Should I fear this happen? do not know why, but lately it has given me afraid.

pic related, black hole.

[Anonymous No.8426248]

>>8426126
Yes, you should fear that shit. It's the only place in the universe where time stops being a thing. You quite possibly could literally go through the process of dying forever dude, we don't know.

[Anonymous No.8426260]

We could detect the gravitational influence of an actual black hole, and it'd probably be floating around like a tiny planet in the vast void of space.
>implying black holes are spooky
Now, I really fear the random gamma ray bursts that just happen when stars die, or black holes in the centers of galaxies are firing high energy radiation in our direction.
Well, I guess, black holes are scary if you look at them like that.

But it's indirect

Die for one of them is my fear, do not know how I would die, it would be no swallowed up by it, maybe our planet would be released directly to the sun or straight out of the solar system.

Only I'm afraid to die for one, and I repeat my question:

Is it okay to be afraid of this? that one is to blame for my death (and therefore of all humanity)

time doesn't stop on it's surface, it just gets "slow" as measured by an observer not squished on the surface. Time is affected by high speeds and high gravity wells. It is matter - it has mass and takes up space. it's still a solid spherical mass with a surface, just super dense. It's not a mystical portal to another realm.

I've heard it flown around that the 'gravitional object' that might be 'planet x' could be a damn small black hole at around 300-600 AU at around 10 earth masses.

While it's no threat, it does mean those fuckers might be either more common than we would like them to be or we got the short end of the stick.

[Anonymous No.8426746]

That would be amazing if Planet X was actually a small black hole, assuming it had a stable orbit that wouldn't wreak havoc on the planets or the Sun. Just imagine the research potential if we could study one of them up close instead of having to study them from thousands of light years away. We could have a live recording of matter being absorbed by a black hole in real time instead of artistic interpretations and grainy pixels from telescopes.

How is that "the short end of the stick"? a 10 Earth-mass black hole that's within reach of current spacecraft would be amazing.

[Anonymous No.8427685]

maybe black holes are shits that dont have atoms, but rather is a void. so when a black hole hits us all our atoms get succed up by void

[Anonymous No.8427792]

>>8426506
That literally has never crossed my mind, although the mystery planet is said to be responsible for sending Oort cloud comets towards the inner Milky Way. Would that make sense to be a characteristic of a black hole? (Serious question by the way not just being a dick chin) Like would it make sense that if an object barely survived the escape velocity of the "suction" of the outer regions of a black hole it could be thrown off course and head in a sketchy direction or is escape velocity even a thing with blakk hulls

[Anonymous No.8427803]

>>8426126
Non /sci/ poster here, wouldn't a black hole just change the orbit of our entire solar system instead of sucking us into it? Such an enormous gravitation pull, what are the odds that it would be coming at us in the right way to actually pull us in vs just make us spin off in a different direction?

[Anonymous No.8427823]

>>8427792
A hole that small would likely evaporate,
Even if it somehow didn't evaporate it would be very easy to spot if there was a black hole in our Solar system.

How large can black holes get? Whenever I try to look that up, I just get "as large as 99999999999 suns" instead of a concrete number.

[Anonymous No.8428514]

I'm curious about this too. If they can be stable infinitely, or if at a certain point they're physically incapable of absorbing matter quickly enough to offset what they're radiating.

[Anonymous No.8428519]

>>8428514
According to this site, they can be infinitely large.

I don't know how reputable he is, though.

>How large can black holes get?
as size i guess you mean the size of the schwarzschild radius.
the schwarzschild radius is given by r = 2*G*M/c^2, where G is the gravitational constant, M the mass of the object under inspection and c is the speed of light.

for M -> infinity the radius becomes infinite and therefore the black hole grows infinitely large. BUT M is not infinite in our universe, therefore a limit for the size of a black hole exists.

The universe is so large and hostile. It's fucking terrifying how precarious our entire existence is. There are so many threats out there that it makes our daily lives seem like a complete delusion. Of all the things that could kill us I am scared of faggots like the OP the most.
