Did we “accidentally” bring new bacteria to the moon or Mars via our space exploration programs?

Probably, and that’s why terraforming is a bad idea. Inside the scientifically minded community, there are two distinct ideas. Don’t contaminate. Leave whatever planet it happens to be in the original pristine condition so we can study it. (This is the predominant, tree hugging concept.) Screw number 1. Terraform the planet. Make it livable for humans, […]

What is combined single directional speed of earth rotation, Earth orbit, solar system transit, galactic spin and transit, and universal expansion?

Yes, we’re all over the place. Speed is relative. The sun orbits the galactic center at about 514,000 mph (143 mi/s) within its trajectory around the galactic center, but as we orbit the sun sometimes the Earth speeds up or slows down relative to the galactic center. Round and round we go. It’s kind of […]

In reality they are related to several other Earth critters. They are a mullusc and belong to the class cephalopoda along with squids cuttlefish and […]
