Relativistic Drag: The Hidden Physics Complicating Interstellar Lightsails
New research reveals that at relativistic speeds, light itself creates drag on solar sails, complicating interstellar travel. The Doppler effect and light aberration reduce thrust and even create resistance beyond 75%
Key Takeaways
- Lightsails face drag from photons at relativistic speeds due to Doppler effect and light aberration.
- At 75% of light speed, diffuse scattering becomes a drag force.
