How Much Is a Hamster?

According to general relativity a black hole hamster would be less than 1.5 times 10 to the negative 28 meters so that's a really pretty tiny number whoa what is that down to the size of like an atom maybe or how much is an angstrom? But we don't think that general relativity is an accurate description of what happens when things get really really small because that's when quantum mechanics takes overQuantum Mechanics tells us the universe is not smooth and continuous but it's discrete that matter is broken up into chunks and even space is quantized. So in order to answer this question we need a theory of quantum gravity that can explain why there are these 'black holes'
