will we ever be able to completely understand blackholes? Is it even possible?

[Anonymous No.1085447]

We can ask them.

[Anonymous No.1085456]

>>1085447
I'm not doing it. you do it.

[Anonymous No.1085457]

>>1085427
It all has to deal with the person, one might think more technical or analytical then the other

so in essence One can say they understand a black whole but its all in your own mind

if your talking about if we can have the world and mark up a formula for such a thing then i think it will take about 100 years or more

lets see with the LHC what happens

No one REALLY understands black holes (at least beyond the event horizon). At this point, our maths can't explain it, and there's no way to observe what's going on in there.

So no. At this time, it is not possible.

I think a black hole is more like a giant nucleus of an atom so packed together thats it actualy might not be vary "HOT", just a little warm and extremely dense. Just imagin, most dont blow up, just keep getting bigger.

So what if over a long period of time, they just keep growing, consuming everything.

Two black holes will be able to interact from a pretty long distance.

Its a know fact that the univers is slowing down (but not that fast) so what if in reality the matter dispenced in the "Big Bang" doesnt travle far enough to escape from all the black holes and just get pulled back together just to do the same thing again?

if you could get into one...wouldnt all the energy it has sucked in just vaporize you? For instance if it was eating part of a star.

Fucking answerd with an even more confus questin

[Anonymous No.1085534]

pink elephants in spandex shitting diamonds might as well be in black holes. Anyone's guess is valid since we cant even fucking infer as to what happens inside black holes. Thats cool to think about though.

[Anonymous No.1085538]

god damn it /sci/
why dont you google your questions before coming here and posting them
do you seriously think youre going to get a better answer from an anon than wikipedia or an academic source?

to answer your question, we probably will understand them and it probably is possible

The reason I say it might just be a little warm is that compreesed matter does not hold as much heat as loose matter does.

[Anonymous No.1085544]

>>1085515
its not hot its very cold

i think its colder than space

[Anonymous No.1085546]

I think it works the same way you squeeze a bar of soap in your hands in the shower it just shoots out

the theory of relativity states that if you are closer to a black hole your time goes by faster
so maybe its going so fast that we just are catching up to the blast/squeeze

if fuckign light cant escape it then what tells you that there's energy being stored in a black hole?

[Anonymous No.1085566]

>>1085559
because black holes can eat stars?

[Anonymous No.1085571]

A black hole is what happens when a super massive star switches from fusing hydrogen into helium, to fusing iron into much heavier elements that can't exist on Earth. The star then blows it's lighter mass out into space, leaving empty space between the heavy particles. The heavy particles all fall in on themselves and as they fall, they crush and fuse with eachother under compression, becoming heavier and more densely packed. This event is what we call a super nova.

It takes about two years to play out, and in the end, the mass (or weight) of a star a million-trillion times bigger than our sun falls in on itself with so much weight that it's crushed to the volume (or physical size) of a baseball or smaller. The result of that is what we call a "black hole" because its something so massive and yet so small that it bends space-time with such incredible influence that not even light can escape if it gets too close.

Imagine two balls (lulz) dropped from 10 feet on a sheet of silk suspended above the ground. Both balls are the same size. One is a standard baseball, the other is a lead cannon ball. The silk is space-time. The baseball is our sun, it will bounce, and make a neat little dent when it lands and everything else on the sheet will roll towards it. The lead shot is a black hole. It's so heavy that it's going to rip the shit out of your silk, and anything that goes near where that cannonball passed through is going to fall through the edge and never be seen from again.

This is understanding a black hole. It's all about gravity. If you think CERN is going to make one of these by smashing protons together, you need to whip out a set of scales and learn the difference between an ounce, and a tonne, the difference between plutonium and hydrogen, the difference between a quasar and a proton.

what was your point there i dont understand?

[Anonymous No.1085589]

>>1085585
they have energy by sucking it in.

[Anonymous No.1085609]

>>1085589
I dont think your understanding. the most basic form of energy is light a wavelength. if light cannot pass a black whole i will ask again what tells you that a black whole is emitting so called energy that you speak of

if it is storing or shooting out or even crushing energy
a form of heat would not be present
as heat is measured by radiation in space

[Anonymous No.1085613]

Look up Quasars, they're black holes that are more massive than our entire galaxy. They have so much matter flying around them that they're the brightest objects in the universe. But once it falls past the event-horizon, it becomes part of the nucleus, and no longer exists as part of the rest of the universe.

[Anonymous No.1085615]

>>1085609
who said emitting?

[Anonymous No.1085619]

>>1085571

You almost got it right. Right enough for anyone curious for sure.

[Anonymous No.1085620]

>>1085615
thats what heat is!!!?!?!??
i don't understand why you don't know what heat is!!

[Anonymous No.1085624]

>>1085620
heat is emitting huh? Heat cant be stored inside blackholes then?

[Anonymous No.1085628]

>>1085619
then explain and make it completely right.

[Anonymous No.1085641]

>>1085624
It may be in the form of energy yes i have no idea.
but what you said
"The reason I say it might just be a little warm is that compreesed matter does not hold as much heat as loose matter does."

warmth is a form of energy being given off so ill ask again if light cant escape it then why would anything like warmth sound even kiddy cats be able to escape it?

waves, how does they work?

[Anonymous No.1085692]

how do transparent surfaces work?

[Anonymous No.1085696]

last year my physics teacher said someone wrote >400pages of math on how black holes work. The same author also said black holes were very simple.

In other words, some people do. You'll have to learn more to understand them (and find this guy's book, i honestly don't remember any more about it)

photon hits an electron in the glass, excitation of electron increases it's energy (i think it may move up a state) and releases another photon on the same path as original one (electron moves down a state), this photon does the same thing, etc. until the last photon is out of the glass.
