I’m going to die anyway. What’s a few years? I’d want to see what the aliens looked like and I’d like to ask how they managed to go faster than the speed of light to get here just to conquer this miserable, little planet.
Let’s revisit Sir Isaac Newton’s cannon. In the above mentioned article we had placed a level on the cannon and shot the cannonball at 1440 feet per second parallel to the ground until it fell and bounced and rolled and came to a stop. We didn’t want to shoot it up in the air in a... Continue Reading →
Since GPS achieved Fully Operational Capability on July 17, 1995, GPS has become an essential navigational tool for civilians and military alike. Keeping the system up-to-date has proved to be a problem. Originally the system was supposed to be up and running in February of 2016 but has been delayed at least until 2023. The latest...

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... Continue Reading →
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... Continue Reading →
It is already more polluted. It has so much CO2 that it is uninhabitable. The atmosphere is too thin to breath and the solar rays from the sun are deadly.
Hypothetically, we are living in an infinite universe. How far is a “near planet?” If the planet is within a very close 200–300 light years, then there might be some possibility, within 200–300 years, that we might detect each other. If the life form is on the other side of the Milky-way, or in another... Continue Reading →
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 prestine condition so we can study it. (This is the predominant, tree hugging concept.) Screw number 1. Terraform the planet. Make it livable for humans,... Continue Reading →
