The morelarger the mass, the more energy can be produced. And we didnt still findhaven't found any fuel which gives so much energy within small quantities gives the needed amount of energy. I know uyou will be thinking of nuclear energy....weenergy; we cannot fit a nuclear reactor with current technology inside a rocket with current technology, and even if we can fit it I dontdon't think our existing knowledge of nuclear science is sufficient to ensure accident free-free reactors at such velocities.
