It’s too late for that. Mars maybe did have a “livable” or as you might say “Earth-like” atmosphere one time, long ago. That time is past. It would never again happen without human assistance. It’s why we still search to see if any microbes or life of any kind ever existed there. So far, nothing.
My wife and I own one of these critters, called the Amazon Echo. It's been a great addition to our household. We have, for example, much more music in our home than ever before. However, Alexa, as you address her, is far from perfect. Here's some Echo "Alexa" bloopers! Try it at home if you... Continue Reading →
I rather liked the idea of lava spewing out of the hole, but I’m just going to take the question on merit and assume you really could drill a hole through the earth and jumped inside. Would you pop up the other side? (Assuming, of course, the other side wasn't under the ocean! Ooops.) No.... Continue Reading →
This is an image of Newton’s Cannon. Given a high enough elevation, shooting a canon-ball at increasing velocity will cause it to travel further and further until it just goes into orbit, falling around the earth. That is what’s happening inside the ISS. It’s called free-fall - the same as Newton’s canon-ball. The ISS is falling toward... Continue Reading →
The moon has 14.6 million mi². The earth, meanwhile, is 70.8% covered with water. What sticks out of the water covers 57.5 million mi². This means there’s only 3.9 times more land on Earth than on the moon. The moon takes up more than 1/3 of the landmass of Earth above water! Put that in your pipe... Continue Reading →
If not miraculous, then pretty darn incredibly fortunate for us. So far, as we study our planet and the places we either visit directly or send our robots to, we haven’t found any other place with life on it. Finding life on another planet would be great. It would prove it wasn’t a “miracle” for... Continue Reading →
No, Pluto has not been reclassified as a planet and as long as Eris is out there, bigger than Pluto, it will have to remain a dwarf planet, Captain Kirk. The discovery of Eris was a main reason why Pluto was “declassified.” Otherwise, how many planets are we going to have to claim exist? Is... Continue Reading →
Let’s turn this around and look at the one place on Earth we know has more pressure than anywhere else: Challenger Deep, the deepest part of the Mariana Trench. It’s almost 7 miles down. If you drop a 100 kg steel ball down into the ocean there, that ball will not vaporize. It might, however,... Continue Reading →
