Extra-terrestrials may not want Earth as part of their galactic empire

A conquering interstellar civilisation could bring the entire galaxy under its yoke in about a million years, assuming said civilisation could traverse the Milky Way at about ten percent the speed of light. I expect it’d be a multi-generational undertaking.

It’d also be up to those who conceived of the original vision to conquer the galaxy, to find a way to keep their descendants motivated. A million years is a long time.

This might be one reason why we’ve not encountered any extra-terrestrial lifeforms so far. No one has the energy to invade the whole galaxy, so they’ve stayed in their corner, undetected. But there is another possibility. The all-powerful invaders are being picky.

They’re only acquiring sections of the Milky Way, and the planets in those regions, that are of some sort of value to them. Perhaps Earth is not in that category.

This is the upshot of the latest Kurzgesagt video presentation. An interesting theory. We are not alone, but we are not wanted.
