Yeah the amount of heat a data center vs a satellite your going to super heat the space in that orbit over time. It they are geostationary then its even harder as the the data center doesn’t move away from the heat.

My question is always how the hell are you going to cool them. Do you know hard it is to move heat in a vacuum?

It boils down to one thing let’s say they find us or we find them. They set out on a trip to us traveling at near C speed. By the time they reach us we may not be around anymore as thousands of years have passed. The universe is so vast not only do catch them in space but also in time. The lack of contact is just a series of near misses.

Its like going physical you get both with the right ripper
