They might already have a pilot license. This setup costs way less per hour than actual flying. And it lets you try things that would be risky in a real plane. Or you can practice bad weather or equipment failures safely, so you can better handle a real situation if it occurs.
No. I rounded off the numbers. A Mercury day is exactly 2 Mercury years. Which is why it’s “in resonance”. That means that gravity will speed up or slow down the rotation to keep the ratio stable over time.
Mercury orbits the sun every 88 earth days. It spins on its axis every 59 earth days, relative to an outside observer (sidereal day.) That makes the solar day (from sunrise to sunrise) 179 earth days long.
I mean, when you wake up normally “fully refreshed”, how long can you go? 16-17 hours is all I get, unless I really push it. The description doesn’t say you don’t get tired, just that there’s a 20 hour cool down.
But when you wake “fully refreshed” you are only good for the next 16 hours. Then you will be tired like any end of day, and out of sync with everyone else’s schedule, and still have to wait for the 20 hour cool down.
It means they either roll it more tightly (more layers per inch) or they make the roll bigger (hope it still fits your roll holder) to stuff more paper on each roll. So they are advertising the package as “72 regular rolls” when it’s only 12 physical rolls.
One of the previous theories had the head in the middle and tail at the edge of the arms. But this study showed that the DNA markers for “head” are expressed all through the starfish, and there are no “tail” markers at all.
