Abstract

It has been suggested that our local galactic environment, through cosmic rays, can affect our terrestrial climate. Remarkable correlations between cosmic rays and climate have been observed across timescales stretching from weeks to galactic years, but only last year an actual microphysical mechanism relating cosmic rays to cloud formation was demonstrated in the lab. This finding substantiates that the solar system is not merely evolving inside an isolating bubble in its host galaxy, but a spaceship experiencing and reacting to its local galactic environment.
