ඔයා කියන දේ හරි වෙන්න පුලුවන්.මම මේක සම්පාදනය කරන්න කරුණු ගත්තෙ වෙන Article එකක් කියවලා.ඒකෙ තිබ්බ කරුණුයි අන්තර්ජාලයේ අඩංගු දේවල් වලින් තමා මේක නිර්මාණය කළේ.
Formation and evolution
Considering the exotic nature of black holes, it may be natural to question if such bizarre objects could exist in nature or to suggest that they are merely pathological solutions to Einstein's equations. Einstein himself wrongly thought that black holes would not form, because he held that the angular momentum of collapsing particles would stabilize their motion at some radius.
[59] This led the general relativity community to dismiss all results to the contrary for many years. However, a minority of relativists continued to contend that black holes were physical objects,
[60] and by the end of the 1960s, they had persuaded the majority of researchers in the field that there is no obstacle to forming an event horizon.
Once an event horizon forms,
Roger Penrose proved that a singularity will form somewhere inside it.
[21] Shortly afterwards,
Stephen Hawking showed that many cosmological solutions describing the
Big Bang have singularities without scalar fields or other exotic matter (see
Penrose-Hawking singularity theorems). The
Kerr solution, the
no-hair theorem and the laws of
black hole thermodynamics showed that the physical properties of black holes were simple and comprehensible, making them respectable subjects for research.
[61] The primary formation process for black holes is expected to be the
gravitational collapse of heavy objects such as stars, but there are also more exotic processes that can lead to the production of black holes.

If all nuclear burning in a star greater than about 1.4
solar masses were to stop, and the
star allowed to cool and solidify, the solidified material would not be strong enough to support its own weight, and it would collapse as the
electrons were pushed into the protons to make neutrons. This
neutron star material is stronger, but the star would be only about 20 km in diameter. If you piled on more material, you would eventually get to the point where there is so much gravity that not even the neutrons could hold it up, and the star would collapse into a black hole.
