What I was thinking is that if dark matter particles don't interact electromagnetically or by nuclear forces then what is there to stop them coming arbitrarily close to each other thus forming microscopic black holes? And shouldn't we then be able to detect them by Hawking radiation? Does the fact that we don't, tell us something about the nature of dark matter (such as that it must interact in some other way) or about Hawking radiation or am completely on the wrong track? Thanks.
