How black hole form
WebBlack holes of stellar mass form when massive stars collapse at the end of their life cycle. After a black hole has formed, it can grow by absorbing mass from its surroundings. … Web16 de nov. de 2015 · Therefore in this sense a black hole's density can be zero. Real astrophysical black holes have to form by gravitational collapse, and the ones we observe also seem to be accreting additional matter at some rate. The density of the infalling matter is quite low, probably comparable to a pretty good laboratory vacuum on earth.
