According to the law of conservation of mass a black hole shouldn't exist right?

Question

If a black hole takes in matter and it is destroyed. Is this matter converted to the large amount of radiation and energy being dispelled from the black hole?

Answer 1

Any matter that falls into the black hole adds to the mass of the black hole. It just doesn't vanish.

Answer 2

The matter falling into the Black Hole is also being recorded around the edge of the accreation disk at the edge of the event horizon. This is so "no matter is lost" in our Universe. ALL that is being stored on this side is the information, not the actual matter, but since information being stored about the matter equals out the information being taken into the black hole there is no real loss to the Black Hole from this side, everything balances.

Answer 3

Matter that falls into a black hole is not destroyed. And matter that is converted to energy just before falling into a black hole is conserved as the energy equivalent of matter according to the famous equation E=MC^2 and is conserved.

Answer 4

I believe that black holes do not technically actually exist in their true form. They are a point where zero is approached but never reached. For example spiral galaxies are all compressing and disappearing into a black hole point in the center of the galaxy as a fibonacci spiral - but again - this "true" zero point is not actually ever reached.

What must hold true then, since the mass is converted to energy is that the entire energy of the galaxy is being fed into this point. So it must be almost zero mass and energy that equates to the sum total of the energy if the system that is spiraling into it.

Black holes (or the concept of them) have to exist to compensate for the "infiniteness" of the universe and maintain the law of conservation of energy in our ever expanding universe.

Answer 5

Actually, the black hole does not destroy the mass that falls into it. It just compresses that mass into a point of zero volume (infinite density). Just what actually goes on inside of a black hole is not known. Our understanding of physics breaks down once we cross the event horizon. However, just because we don't understand what is going on does not mean that black holes don't exist. The evidence for their existence of these things is pretty well established. Now we are just trying to explain them.

Answer 6

One of the few characteristics of a black hole is its mass. Any mass falling into the black hole only adds to the mass of that black hole, so conservation of mass-energy is preserved. Similarly, black holes can have charge and angular momentum.

Answer 7

HA... conservation of mass could somewhat be said as a regulation. Its violated for all time in nuclear reactions and in common particle interactions in quantum mechanics. purely entire potential is conserved. as far as black holes? No they don't violate any conservation ideas. even as they "eat" something it delivers to there mass and to the realm of their journey horizon.

Answer 8

in the light of new findings law of conservation of mass doesn't hold good anymore.
the law that is true today is "LAW OF CONSERVATION OF MASS AND ENERGY" according to which total mass and energy of any isolated system are conserved as mass and energy have been proven to be interconvertible according to the relation E=MC^2

Answer 9

I think most of the mass is still there, which explains the tremendous gravitational field of the black hole.

Answer 10

Some matter is accumulated and other matter is converted [thanks to E=mc^2] to energy and emmitted.
