Here it is The Great Internet Black Hole Survey; or a continuation of; which im sure will provide interest to many;

(as taken from the book 'Black Holes a travellers guide')

Thankyou :)

1.[Public or otherwise] Misconseptions [about black holes]; That black holes are huge vacuum cleaners that suck everything in to themselves; more specifically; a misconseption that if our sun (theoretically) was to collapse into a black hole it would suck the solar system into it.

 

2.Public Fasination. A Morbid curiosity we have about our demise.

 

3.Useful Function. Tiny black holes can emit huge amounts of [Hawking] Radiation (or so says the theory). Can we harness this power?

 

4.Unsolved Problem [You would like to see found out]. The theory of interstella travel via a rotating black hole; and furthermore an invention of 'exotic' matter to keep the wormhole open.

*Black holes do fuse together in a round about way. When they merge its sometimes refered to as black hole 'cannibalism'. These events are thought to emit huge amounts of the as yet undected gravoty waves. Yourdadonapogos I answered that one already and it is a resounding no.

 

1. Misconception: Black holes are black!!

2. Public facination: Nothing can escape, sort of like marridge.

3. Useful function: The ultimate in gravity slingshots. They're useful for making galaxies too.

4.Unsolved Problem: Resolving the paradox that arises when taking about singularities when it is clear all Black holes have varying mass. Hawking radiation and whether black holes evaporate.
