According to the new Grabby Aliens theory, there might be thousands of huge alien civilizations in the universe right now… and we could join their ranks very soon.
Interstellar cultures may be divided into two categories. Aliens that are “quiet” don’t grow or alter too much before they perish. Since we have so little information on them, we are left to mostly guess using tools like the Drake equation.
In contrast, “loud” aliens dynamically adjust the volume levels under their command and continue to rapidly grow until they collide. It should be possible to see these aliens with the naked eye and draw many conclusions from our data about these noisy visitors.
