New Study Predicts Aliens Do Not Want to Visit Earth

The authors make the case that civilizations could take advantage of close stellar encounters to rapidly expand across galaxies without the need for relativistic spaceflight.

In particular, we note that the low-mass Galactic Club, originating from the G-dwarf parent system, would have had plenty of time to develop in galactic history without us noticing its activity.

But we don't know much more about whether the such galactic-scale expansion will be common or desirable for technological civilization in general.
