This does not affect what kind of radiation they absorb; what it affects is the size of the event horizon. The more massive the black hole, the wider the event horizon. This is because gravity and mass are directly related. A black hole formed by the collapse of a star will have a mass many times that of our Sun. The supermassive black hole at the center of the Milky Way is vastly more massive. But you can even have small black holes. A black hole the size of the Earth would have a very small event horizon. I once posed a question here about a black hole with a mass of one kilogram. I suspect that such a tiny black hole would be able to pass directly through the planet without actually hitting any matter because it would be so miniscule. But I don't know the math required to figure it out.<br /><br />Black holes are often thought of as monstrously huge objects, but actually they don't have to be huge. What makes something a black hole is *density*. If the mass is compressed into a sufficiently small space, there will be an average orbital altitude about the object such that escape velocity is c. But if the object is not very massive, then that altitude is going to be so close to the object that it might be able to pass directly through another atom!<br /><br />Weird but true. That's the sort of black hole that physicists talk about possibly creating in the lab. Such a black hole is far too minuscule to be any kind of a threa <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
