Faster than Slower than Light

In the last article on Tachyon Rocketry, it appears that even a rocket propelled by tachyons is limited by the lightspeed barrier. The problem is that our bodies (and our starship) are made of electrons, quarks, and other particles with real, non-zero mass. In the context of faster-than-light tachyons, such particles are known as bradyons … Continue reading Faster than Slower than Light

Photon Rockets for Interstellar Travel

Say you want to build an interstellar rocket. Cool beans. What's the best way to go about it? Well, to get the highest possible delta-v, you want the highest possible exhaust velocity for your rocket propellant. So what's the fastest thing in the universe? Unless you're living in a universe with FTL, that would be … Continue reading Photon Rockets for Interstellar Travel
