Suzy, you could just use a fusion rocket, without messing with a HEAVY black hole.And antimatter rocket would be better anyway.

For conservation of energy to maintained, a wormhole or similar conveyance would require a minimum energy input of the difference in potential and kinetic energy between one and and the other in order to work

Traveling at the speed of light is instantaneous to the traveler, so I suspect that c is effectively infinite speed, and it's just simply a matter of the ways we perceive and measure time and space don't work well at such extremes. Looking out across the universe, a star 1 light year away is seen as it was one year ago - so the x,y and z coordinates can be viewed as distances in time. Then c is 1s/s, or just 1 without units and you can't travel faster than 1. There, now that sounds better than you can't travel faster than ~3e8m/s.

Can't agree on "c is instantaneous", why radar bounces off planets come back with delay?

Kaluza Klein Theory...

This weeks New Scientist (1 August 2008) has an article about how antimatter particles sometimes bounce off normal matter.

This possibly supports my previous assumption about the possible anti-gravity that might occur with anti-matter.

Kaluza klein theory...Not exactly...as far as I know the equations don't show dark energy or matter..However, there is a compactification.. but primarily it links gravity equations to EM... and vice versa.. I speaking of the 5D case of course.. the other stuff really is nonsense.speaking of the 11 dimensions..

Miguel Alcubierre took the idea to the extreme by positing large masses: neutronium density or more. Further he used a nifty little gravitational trick: the gravity field inside a spherically symmetric shell of mass is zero--in general relativity terms, the spacetime inside a spherical shell is approximately flat. So putting the two ideas together you get a spherical shell with the forward end composed of positive energy matter, the aft half is composed of negative energy matter, and the 'vessel' or transport is at the center of the shell in the flat spacetime 'island' in the middle. Increase the density of the shell until it comes close to the density of neutronium, and voila you have massive acceleration that the occupants inside won't feel (they're in free fall.)

Creation of Mini black holes?

and capturing virtual particles?any thoughts, known papers, etc?

any sufficiently dense object (possibly a neutron star just a bit shy of unrestrained collapse) can have a photon sphere. That is, the object through it's deep gravity well can actually trap photons in orbit around the object. Anything moving slower than that will be trapped in higher orbits. One can then attempt to scatter observable stuff off of what is in the photon sphere.

IIRC lowest stable orbit around non-rotating black hole has a radius of 3*Rs.
