studying black holes

February 4, 2007 6:34am CST
Stellar collapse will generate black holes containing at least three solar masses. Black holes smaller than this limit can only be created if their matter is subjected to sufficient pressure from some source other than self-gravitation. The enormous pressures needed for this are thought to have existed in the very early stages of the universe, possibly creating primordial black holes which could have masses smaller than that of the Sun. do you think we can go through them?

The primordial black holes are theoretical objects. There were temperatures and pressures a very short time after the Big Bang that were high enough so that quantic fluctuations could form them. Stephen Hawking found in his theory that the black holes evaporate. The more massive the black hole is, the more quickly it evaporates. Black holes of three times the mass of the Sun evaporate in a time much longer than the age of the Universe. More massive black holes could evaporate in a near future. This explosion could be detected. A brief history of time is the book of Stephen Hawking where you can read more about it.

Nice theory about black holes. Anyway I doubt that we can go through them. Only way could be artificial black hole. :) There exist one technology for fast jump through outer space but only in Sci-Fi . It's named Plasma accelaration.. :)

i didnt get your question of going through them, for a star to become a black hole or a dwarf or a neutron star it depends on its initial mass, the forces you are talking about are just a suggestion, still i didnt get what you meant by the last line of your post, as far as our sun is concerned then the most possible scenario is that after becoming a red giant after about 7 billion years, it may explode like a supernova and then contract into a dwarf with the size of the earth if the sun becomes a black hole , lets say then its radius according to Schwartzchild equation wont be more than a couple of centimeters

hi,i think further studies to be needed in this theory.scientists also have disputes on this theory.
