View Full Version : IF an event horizon doesn't form..?

Reading about Tanmay Vachaspati, Dejan Stojkovic, and Lawrence Krauss work about whether or not an event horizon actually forms, in a collapsing blackhole type body,



I have wondered whether, if an event horizon doesn't form, would a neutrino pass straight through one?

Would its passage be slowed down by gravitational time dilation, and if so by how much?

If there is a type of dark matter, and it can pass through ordinary, baryonic, matter; would that pass through a non-event-horizon-black-hole-type body(Black Star), and out the other side?

Perhaps dark matter would go in and out of a black-star in a kind of an orbit?
