The aliens have the same physics we do. Science isn't magic. Without quite literally having to replace everything we have known or discovered in the past 250 years from entropy to electromagnetic theory to gravity to motion with brand new theories that somehow equally explain all known phenomenon while also allowing lots of outright magic, no, the aliens are not able to collect radio waves from below the noise floor. |

Show a spacecraft to someone from the middle ages and they would think it's magic.
There is physics that has not been discovered. Lots of things are still unexplained.

Before we had quadrature modulation and quadrature phase shift keying, we thought we had hit the noise floor for wireless bandwidth. After we thought we really hit the ceiling, we had beamforming. There's stuff that hasn't been thought of. We don't know the unknown unknowns.
