(moderation:
There is a nice article on the New York Times (registration required) on a Black Hole Flight Simulator built by prof. Andrew Hamilton at the Denver Science Museum. The simulator was built using Open GL but very few details are available.

Sounded neat, Tullio, so I googled it and found this NASA article: The Black Hole Road Show Kicks Off in Denver
Thanks for the post about it!

Hmm... details would be interesting.
I'm sure it's not as fancy, but for a while there has been a sort of neutron star flight simulator on the web. On second look, it's got some black hole stuff too.

Ben... I'd like to check this out, but your link takes me to M$'s homepage...

i just wonder what this simulator really shows ? the estimated 3D flat reality projection (what flyer thinks is now around him) OR the real experience of the flyer i.e. what he sees with his own eyes during the flight (namely the light that reached him from passed events around)?

On a similar note, I just ran across an article about some computer calculations showing how space warps as two black holes merge. They have some nice pictures and even a movie!

E@H could might be able to detect two inspiraling BHs. The gravitational signal should be similar to the neutron star pairs E@H is looking for. the BHs would have higher masses, which might push the signal outside the expected norms. E@H wouldn't detect the high aimplitude transient signals from an actual merger or formation in a supernova. I assume LIGO is checking for them using a different tool though.

I don't think so. Not per se, anyway, but it could add evidence. You'd have to put a lower bound on mass with an upper bound on the volume it was contained in. That way you could say the density exceeds some critical value ( whatever general relativity predicts ) so that a black hole must be there. The gravitational waves if/when detected from a non-spherically symmetric process ( ie. with a 'quadrupole moment' ) like a merger, and if at a known distance could conceivably put a lower bound on the mass(es) involved. But I'm not sure that it is currently known how to determine the expected signal characteristics of say a BH/BH merger so that it 'weighs' the event ( based on that signal alone ). It would be nice if I'm wrong, though.... :-)
