How was the data transferred across galaxies?
In Interstellar, they have shown that the astronauts Mann, Miller and Edmunds were sending signals to NASA (Earth) through their beacons.
Also NASA is able to send videos recorded on earth to Cooper and his team while they are in all together a different galaxy!
I want to know whether this is possible and how? How can you send data (heartbeats through beacons and videos) to and from earth and planets of unknown galaxies?
Best Answer
They were sending the data through the wormhole orbiting Saturn. It was mentioned there were satellites on both sides of the wormhole to enable the communication. The signal would be delayed approximately 1.4 hours because of the distance to Saturn and possibly more because of distances on the other side. So the direct radio/video chat would be impossible.
