They are from American Weekly. I will check on the date for you as soon as I can.
Energy is not destroyed at the moment of the Heat Death. Instead, entropy has reached its maximum. If there were a region with less energy, then energy could indeed flow toward it...but then that would mean that entropy has not yet reached its maximum and that the Heat Death of the universe has not in fact yet… Read more
Should instead be making a film version of Lindsay Gutteridge’s Cold War in a Country Garden.
One of the reasons a definition is important is that scientists need to know they are talking about the same thing. If “mammal” meant one thing to one scientist and something else to another, it would be impossible for them to communicate effectively if it turns out that one of them is including sea cucumbers in his… Read more
Von Sydow would have been terrific! To this day, I keep imagining different actors as Nemo in a future remake... Just the other day, I thought, gee, how about Patrick Stewart?
No, not exactly. The universe itself really has no center in the way you may be thinking of it. Everything in the universe is expanding away from everything else. An analogy that is often used is to imagine spots drawn on the surface of a balloon. As you inflate the balloon, all the spots grow further apart but no one… Read more
Needless to say, I had to take a shot at depicting some of these new worlds myself. Top to bottom: TRAPPIST-1e, TRAPPIST-1d and sunset on TRAPPIST-1b.
And why Deathworld has never been film amazes me.
I do give Robinson Crusoe on Mars a tip of the hat for depicting Mars with a red sky and suggesting that the planet is regularly bombarded by meteorites/asteroids (and that these may even have an effect on the climate). Its depiction of the Martian poles isn’t too far off, either.
If by fullest extent you mean how much of the shadow you can see, it’s because at midnight you are in the same line as the sun, the earth and the ring. This means you would see the shadow at its best. Since the shadow would appear to move across the ring as the earth rotates, sort of like the hand of a clock, you… Read more
The moon probably wouldn’t look any bigger if it had an atmosphere (and a magnetic field wouldn’t help much in keeping an atmosphere—-for instance, Mars has almost no magnetic field and it certainly has an atmosphere). Read more
Very interesting indeed! Thanks very much for sharing this!
Pythagoras is often credited as being the first to realize that the evening and morning stars were one and the same thing, though the ancient Akkadians are sometimes given credit for this as well.
Neither the sun nor the moon were ever considered to be planets. The word “planet,” as I pointed out, referred to what was thought to be a special class of star. Since it was obvious to the ancients that the sun and moon were not stars (whatever else they may have thought they were) they were not included among those… Read more
