If the moon crashed in to earth

[GroundZero]

That old question that you had on the tip of your tongue?, well here is a Kurzgeagt video to explain it.

Putting my phsyics hat on for a moment, I think they pretty much got it as accurate as needed for a short vid. But from a politics and human nature angle. I think they underplay the rampant fighting that would occur between nations for resources leading up to the inevitable. I think this would kick off as soon as people bought up all the bog rolls!

Moon is travelling further away from the earth. Also the earth is slowing down, it used to have over 500 days I think.

Another video on the same subject, this one from Scott Manley:

If the moon disappeared presumably the tides would stop - does this mitigate the effects of sea level rises from global warming?

No, they'll still produce endless graphs and "peer reviewed" studies to show the earth is in a "climate crisis"

[Geffg]

I think the world will always have a climate crisis as it’s a great way to be able to tax us heavily and make a good proportion of the world happy about paying it too.

Actually the core would begin to cool at a much faster rate. The moon not only affects the tides, but it is also constantly squishing the earth like a giant squash ball, which keeps us all warm and gooey inside.

Ah good point, my tongue-in-cheek comment about blasting the moon away to solve sea level rises had neglected the wider benefits of the moon. Still, i'm sure climate denialists might still claim its a hoax as the core freezes and we all turn to ice.

The hot core is due to radioactive processes is it not?

Yes, that's one reason. The other is the tidally-locked moon. IANAA, my source is Prof. Richard Pogge's (Ohio State University) excellent series of astronomy lectures which are available as a podcast (Astronomy 141 and Astronomy 162).

[Dastardly Dick]

Rather than crashing the moon into earth at speed which is going to create a bit of snap crackle and pop, Im more interested in what would happen if we could just land it at a really gentle and controlled pace and let it settle.
Im sure itd cause a wobble......
Would it just break apart and end up like a mahoosive mountain range?

Someone needs to run a simulation.

Indeed. I think there was a post on one of the Covid threads along the lines of “If I pay a load more tax will Covid go away or does that only work for climate change?”

Global Hunger finished.

Tides would still happen, thanks to the big bright thing in the sky.

[Eric Mc]

Solar tides are a lot less than those caused by the moon. Although the sun is much. much more massive than the moon, it is also much, much further away - and the effect of tides is greatly increased as objects get closer.

On that score, if the moon were to approach the earth, it would eventually reach what is referred to as Roche's Limit. This is the point where the tidal forces exerted by the earth on the moon would cause the moon to break apart. We would end up with a planetary ring system much like that of Saturn.

If the moon disappeared, would the actual (ie solar) tide become what's now the difference between spring and neap tides?

Pretty, but a pain to astronomers.

More or less.

At least it would be easier to get on and off Mersea.
