Relativistic momentum:
As the velocity v approaches c, the divisor approaches 0 and the momentum approaches infinity.
And the energy required to accelerate the mass also approaches infinity. The problem isn't getting a few particles to near c - we can do that now in the LHC, the problem is to have a steady stream of reaction mass flying out the back of your spacecraft imparting an acceleration on said spacecraft. The LHC makes a lousy spacecraft engine.AnotherDilbert wrote: ↑Sun Mar 11, 2018 3:09 pmRelativistic momentum:

I agree that the energy requirements are very high and that we certainly do not know how to build such reaction drives today, but they are not theoretically impossible.Sigtrygg wrote: ↑ And the energy required to accelerate the mass also approaches infinity.
