If the heim drive doesn't work, this might:
Let's pretend for a second that we have unlimited energy, and very small (and good) particle accellerators.
I've read thatt it would take infinite energy to push something up to light speed, because at that speed it would have infinite mass. Lets say we push 1-2 thousand protons up to .99999 c in a particle accelerator in the front of a spacecraft. If their mass is increaced due to speed, then they have gravity. Because they are very dense, they might get up to say mars gravity. Put these in 1500 proton groups evenly around the spacecraft, and you have artificial gravity. This could pull the spacecraft along. Would it work?

D'uh, how do you move the relativistic particles' containment ??
IMHO, if you did without that stuff, you could use the saved mass to carry a VASIMIR or similar torch...

As you threw the particles out the front, woudn't the spacecraft move backwards from the reaction, just like our rockets do now? It sounds to me like the relitivistic rocket in reverse.

the way to create gravity is to produce a high concentration of mass in a small spot. Relativistic mass or mini black holes, it doesn't matter. A trivial use of artificial gravity would be to hold something down to the floor of a spaceship or space station, but a supercivilization might someday build a gravitational catapult which could quickly fling something to near the speed of light to reduce travel time between stars.
Even if you accelerated at 1g for half the journey and decelerated at 1g for the remainder it would still take years from the traveller's perspective to reach any of the nearby stars. To quickly attain relativistic velocities without taking most of a year or undergoing crushing acceleration, you need something called a gravitational catapult. There are numeruos ways of making such, the simplest is to have two black holes orbiting each other closely. relativistic particle beams are another idea, but those particles would have to be extremely relativistic to get densities greater than ordinary matter can achieve.

No, more thrown out the sides than the front, or moved in a circle, like CERN.
And I was thinking solar system out to ~ saturn or so, maybe a little farther.
