Do black holes really exist?

[Gravage]

I must say I was searching about black holes!But one simple question remainedo they truly exist?
Yes, I know we can't see them directly,but indirectly.
Still,I think to this day have never proven the evidence of black hole's existence!
Also,Hawking radiation says that black object,but that's another,it has neve been proven by an normal experiment,even if it did,I don't think it works for the black hole thing.

Yes they do. Or at least, their existence is consistent with observations of the behaviour of other, nearby, objects.

there are bodies of mass out there that their gravity is so strong that a radius around them would be unescapable even to light... hence a black hole.

Gravage is right.
Black holes are purely hypothetical. Like dark matter and now dark energy they have never been proven beyound any a reasonable doubt.

As I said earlier "their existence is consistent with observations of the behaviour of other, nearby, objects".
That's not proof of course, but the accumulating evidence tends to support the idea that they exist.

Cheers,

Heres a cool site about them: Cambridge Relativity- Black Holes

Couldn't black holes just be a huge accumulation of dark matter? A very dense area of dark matter would give the illusion of a black hole, right?

What a black hole basically means is a place where gravity is so strong even light is not fast enough to escape… if your example makes that happen then it’s a black hole.

There is tons of evidence for the existence of black holes. Whilst a black hole is truly black, the space around it is far from black. Black hole accretion disks pour out colossal amounts of energy, which we can easily detect. The sources of energy for objects such as quasars cannot be anything other than black holes - at least given current theories.

Your question is: Do Black Holes really exist? Now my reply...
If you are referring to the 'event' or rather what happens to or what is the 'end-result' of a super-massive star explosion many times more massive than our own Sun,....
This term 'Black hole' is incorrectly applied and misunderstood by most cosmologist and even astronomers1
When a very supermassive star becomes a supernova, and its core implodes...this actually creates a hugh hole or rip in the space-time fabric of the universe...exposing the very outer limits or edge if you will of the universe, where the 'dark energy -matter' is to be found!!!
Nothing can ever fall into or escape from this 'edge' of the universe created from such supernova explosions. The idea that some poor astronaut could 'fall' into a Black Hole and turned into spagetti is far fetched and violate the natural laws of physics...if you really think about it.
Light can once again 'break' the common everyday laws of physic during the supernova implosion and for a very brief fraction of a second, travel much faster than its normal space-time velocity!! Extreme temperature and pressure due to tremedous gravity are important factors in contributing to 'photons of light' unusal behaviour.... Does this help?

Black "hole" is kind of a misleading name, which gave birth to "wormholes" in sci-fi movies where they are used to tunnel through space and time, it is just a compact black globe with highly degenerated matter, just like neutron stars are highly compacted / degenerated object , containing strange quarks, perhaps the black globes are a soup of Higgs bosons, who knows?


BTW: what would happen if we send an entangled particle to a black hole/globe/whatever ?

Would we be able to get information about the particle within the event horizon by measuring the entangled particle counterpart outside the event horizon???? or can black globes even shut off this instant "priviliged channel" of mother nature ????

 

[ElectricFetus]

entangled particle are what suck the energy and mass out of black holes.

Faz,

Why do you think nothing can every fall into a black hole?

Not aimed at you Fetus, you're just the last (sensible) posting.

This thread is becoming pseusoscience. Time to move it, JR?

Ok, I really thought about it and it seemed perfectly reasonable. How does it violate the laws of physics?

Ok, you lost me. How does light travel faster than normal in a supernova? What do effect do extreme temperature nd pressure have on light? Please explain what I'm missing here.

I can't do that, even if I wanted to.

Try to get elected as a moderator then? or can mod. not do that?

Black Holes as dark matter and energy sources

Slacker: Now I see you're getting more in line with my personal view of just what the socalled Black Holes really are. . .a 'porthole' if you will, a place where the 'elastic skin' of the universe can and does, 'bleed' through into normal space-time universe we are all familiar with.
It takes the tremendous gravitational (imploding) energy of a very massive star in a supernova explosion to 'tear open' and form a 'rip' in the space-time to 'expose' the dark matter/energy outer elastic skin of the universe where some 90% of the mass of the universe is to be found!
Think of this analogy... A simple child's toy, a rubber balloon, stretched by hydrogen gas. The hydrogen gas represents the 10% of the total mass of the universe, contained inside the 90% of the total mass of the universe, represented by the elastic skin of the balloon!! The more our universe expands, the more this 'elastic skin' composed of dark matter and energy resists this expansion, causing the universe at large to flatten! But 'black holes' punch holes in the elastic fabric of the 'outer lining' of the universe. Where dark matter and energy can and does 'bleed' through into the 10% universe or inner universe, if you will. Clear as mud, right?

Dark matter and energy bleed through

Faz,

Simply put...to answer your question: Why do you think nothing can ever fall into a black hole? Because black holes don't exist..not in the current view of thinking in the scientific community!
These socalled 'black holes' are, and I repete myself, rips or tears in the space-time continuum. A porthole or look into what lies at the very edge or outer limits of the universe!!! Nothing can ever reach or by the laws of everyday physics, thank God, ever be allow to fall into and go through these portholes. The unimaginable gravitation pressure pushing INTO the universe from the dark matter/energy elastic skin now exposed by the socalled black hole, makes it impossible for any particle including light to FALL into this elastic dark matter/energy skin of our universe. Like the air pressure in an airlock at CDC in Atlanta, preventing the lesser air pressure from escaping out.

If you can't stand the pressure...don't go near a Black Hole!

Simply in High School physics we learn that a great pressure that is exerted on a lesser pressure, the greater pressure will prevail every time! The much, much greater energetic pressure or force being exerted by the 'exposed' dark matter/energy porthole greatly overwhelms the gravitational 'contaction' force of the imploded supernova. All and I repete, all matter and energy, including photons of light are stopped at what is called the 'event horizon' from going any further into the porthole! So therefore, any astronaut, of an obvious mass can never be turned into spaghetti (with an h) for he or she would be stopped long before this could possibly happen! See Stephen Hawking's notes on 'bleeding black holes' Some dark matter/energy does indeed bleed through these portholes ..but the mostly infrared energy is very very slow. Thank goodness.
