United States3 months ago - So-S0
Generally ood science/astronomy content, but unfortunately tainted with DEI dogma and recurring leftwing political bias…. Could use a bit more “diversity” and “inclusion” when it comes to worldviews and obvious bias.

P.S. Poor people don’t do polling, so please don’t give us the polling numbers from now on.

Out on the farm where I grew up, it was so dark at night that one could see satellites, planets, the edge of the Milky Way and what I called “foreverland ”! Outer planeta... more
