I'm not sure why Less Wrong is the appropriate place for these kind of questions instead of, say, Reddit's Ask Science. You'd probably get half a dozen physicists jumping over themselves to answer your question over there, no?
I don't know about Thomas, but I sure as heck would prefer to discuss physics on LW (if possible, i.e. if appropriately knowledgeable people are present here) rather than an ordinary forum. Less inferential distance, more common assumptions (e.g. that we're not interested in guessing passwords), etc.
See also here (second bullet). (This post now joins the list of examples.)
As mister shminux mentioned somewhere, he is happy and qualified to answer questions in the field of the Relativity. Here is mine:
A long rod (a cylinder) could have a large escape velocity in the direction of its main axe. From its end, to the "infinity". Larger than the speed of light. While the perpendicular escape velocity is lesser than the speed of light.
Is this rod then an asymmetric black hole?
