Canceling the Cosmos: Can Destructive Interference Shield Astronauts From Deep-Space Radiation?
Passive shielding — piling mass between an astronaut and the cosmos — is reaching the limits of what rocket economics will tolerate. A theoretically compelling alternative is beginning to attract serious research attention: using phase-shifted electromagnetic fields and particle-wave interference to cancel incoming radiation before it reaches biological tissue. The physics is formidable, the engineering barriers are substantial, and the potential payoff for crewed Mars missions is difficult to o
