Unfortunately, this isn't true. The lightspeed limit makes arbitrarily
high velocities impossible, conservation of energy limits available energy
(since your past lightcone is finite, you can never have infinite
matter/energy), thermodynamics limits how much work you can do with an
energy source and quantization limits information densities and makes
spacetime chunky. But we are *very* far from these limits now, and for
the foreseeable future.
