Why Aliens Will Never Reach Earth It's Not What You Think

Even if intelligent alien civilizations exist somewhere in our galaxy right now, the laws of physics may make it impossible for them to ever reach Earth.

From the illusion of the night sky to the Kardashev scale, warp drives, and the Fermi paradox, this is the physics argument almost nobody talks about.
