Do black holes have gravity and if so is it less than a supernova or white dwarf?
In seventh grade you’re learning about general relativity, gravity and five-dimensional tensor algebra? Well then, I say good luck. Yes, a black hole does have gravity, and yes, its gravitational field far surpasses that of a supernova or white dwarf. A supernova is the ‘death of the star’ – one final explosion expelling the matter into space. A white dwarf (and black hole) is one of three possible endpoints to a star. A black hole results when the star cannot balance the crushing force of gravity pushing in on it, and as such, collapses in on itself. Black holes are formed from stars greater than the “Chandrasekhar Limit” (think of this as a threshold where, if crossed, the star does not become a black hole, but a white dwarf). This is the case with our Sun – it is not massive enough to form a black hole upon its collapse, so it will form into a red giant, then supergiant, and eventually into a pathetic white dwarf. Think of a black hole having a gravitational field approaching infini
