Why does the moon revolve around the earth?

It just moves forward. The moon isn’t stationary. It has inertia and no atmosphere in space to slow it down. It just goes. As it moves forward, the gravity of Earth tugs on it and it falls, but because it’s moving forward it misses Earth as it falls and goes around, again and again. That’s […]

Why doesn't anyone else besides me believe in time traveling?

I don’t know the answer to your question. However, consider this. We are not standing still. In time the Earth rotates around it’s axis, the Earth also rotates around the sun, the sun rotates around the galactic center and the galaxy is merging with Andromeda. We are therefore moving at hundreds of thousands of miles […]

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, […]

When is enough enough?

I’m not old. Sixty five. I look younger, but how much more time do I have? Twenty three years from now will be the age my father died. Thirty-four years from now will be the age my mother died. I still have some time. Right? I notice, however, that I think about “the end” a […]

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 […]
