No. The reason it's happening is that Earth's rotation is faster than the Moon's orbit - a day is shorter than a month.

Because of this, the Moon is leeching kinetic energy from Earth's rotation to orbit faster (drifting further away is simply a consequence of orbiting faster). This speeds up the Moon's orbit at the cost of slowing the Earth's rotation. Over time this energy-leeching will stabilize once the Moon has sped up so much, and the Earth has slowed down so much, that the Moon's orbit and the Earth's rotation will take the exact same amount of time - a day will be equal to a month - and the Moon will appear motionless in the sky. This is called tidal locking.

But as other comments have stated, this process will take so long that the Sun will kill us all long before it finishes.

>Differenct grains have been understood to do different things for centuries

the TIL isnt 'differenct grains do different things' its that popped corn is made from a cultivar named after the processing method

cornflour cornstarch cornmeal and creamed corn are usually made from specific cultivars too but none of those cultivars are named after their use and none of those processing methods are exclusive to the cultivar

its not like they call poppable rice cultivars 'poprice'

this is in comparison to two shots. a chain shot can only spread itself out about 2 feet wide. dont get me wrong, it was nasty, but there's a reason it was primarily used for naval combat, and never was consistently used on land.
