Yeah, I don't want to do that if it is over done.
"Oh look, this jerk wants a PhD with yet another Galaxy simulation."
No thanks. I guess that is why I asked. Looking for ideas though.

Wally,
For my Grad thesis project I was thinking about doing simulations of
cannibal or colliding galaxies. Any insight? I read that collisions are
rare due to interstellar distances.
Don't look at me, I don't do galaxies :-)
My intuition says that there's lots of galaxies, so interactions might
be rare, but not that rare. After all, our own galaxy is eating up
another, and Stephans Quintet is supposed to have 4 of the galaxies
actually gravitationally bound.
Whilst rare, my guess is that they would probably happen. The paper I
cited obviously suggests that collisions happen, and certainly did in
the early universe (this makes sense).
If you are going to do simulations, it would be neat to see the
results.
I wonder if the topic isn't over-subscribed, though.
There are simulations which go all the way from a BASIC program in
"Astronomy" magazine (which does an amazingly good job), to commercial
products, to the very latest super-computer simulations which use millions
of particles and include gas dynamics.
But if you think you have something new I'll expect to see a web site with
some beautiful pictures

What have they got to hide? Release the ESA Beagle 2 report.

Hey, I don't want to put you off Ask the experts. There may be new
algorithms, new methods using modern computing power.
Or look at galaxy structure. Really off-the-wall idea - see if you can
incorporate Hannes Alfven's ideas about electrical effects and see if
that gives a better fit than conventional models. He's been dead for
nearly 10 years so unless someone's been following up his ideas there is
room for something new. |

No, John don't worry about it...
I mean, really if I do something I don't want to hear "not another...".
That is just me.
I talked to a astrophysicist today about N-Body problems and Hydrodynamics.
He said I was on the right track. I just need to find the right track. And,
yeah your right. Finding a new way model it would be great. The great
thing is that even though all the "big" ideas have been done already. There
is still room for us to find lots of little great ideas.
So, I think the N-Body problems seem interesting. I think I may hit the
online articles to see what I come up with. Any ideas, shoot em over.
