Physics, Astronomy & Cosmology / Communicating at near the speed of light?
« on: 11/02/2020 09:38:24 »
Hi Naked Scientists,
Is it possible to establish two-way communications from Earth to a spaceship travelling at near the speed of light?
Say I am travelling to the recently reported exoplanet K2-18b, I would spend over 110 years on my way, while on Earth thousands of years would pass. Would it be possible to relay instructions from an Earth-based control base to the spaceship? Does it make sense at all to try to interact with an object travelling at near the speed of light using electromagnetic radiation?
Thank you!
