question about black holes

[skaper]

is black holes bodies of huge or endless mass? if the first is happening why don't they explode with super novas as huge stars? and how can the seccond be posible?

[Mohan.C]

They have so much mass that they cannot explode. But I believe they decay.

[skaper]

so they such as any ather star but the huge gravity does not let the ligth to leave from a specific distance on th gravitational field? so why they are discripeted as wormholes?

Wormholes is just a theory and not been proved by observation.

black holes dont explode...but they do evaporate due to hawking radiation

[mkirkpatrick]

Merv,what would you consider would be left,if anything,after theevaporation
process had tirminated?


regards michael.

[Mohan.C]

I think that is radiation. Evaporation cannot be compared with this.
But I think this radiation is due to an imbalance because when matter gets added into a blackhole there will be imbalance and so there is a radiation or energy comes out to make it more stable.

[mkirkpatrick]

Thanks Mohan my friend,that is an excellent way of expressing this event
which also includes the horizon?

regards michael.

[BRIAN]

This is really appreciable.Mohan I think that the concept specially involved with the radiations.Well thanks for the information.

Good Job

Black holes are the remnants of super novae. Huge stars explode to create black holes. Though there are super massive black holes, the entire mass of the black holes are concentrated at their center. The stars explode because of the imbalance of different pressures in them. But since black holes don't face any such imbalance, there is no question of explosion. One can find good discussions about supernova and black holes here:
