if there is even just one blackhole, wouldnt it just keep on consuming matter and eventually consume everything?
In: Planetary Science
You and three of your friends each pick up a corner of a sheet and lift it so it is pulled tight. Get a fourth friend to through a 1kg bag of feathers into the middle of the sheet and watch it sag with the weight. Now take the bag out and do the same with a 4cm cube of osmium (the heaviest metal, which by my quick search is going to weigh about the same as the feathers). Other than the footprint of the object, there’s not going to be any difference in how the sheet behaves, or how far it sags.
Or to put it another way, if our sun turned into a Black Hole today, the Earth’s orbit would stay exactly the same.
