I was irritated with this one when it came out, and still am, because the people jumping are exchanging gravitational potential energy for kinetic energy and back again. It's not that the Earth doesn't move much. It doesn't move at all. It's the same thing when you launch rockets to orbit, or fly helicopters. There is no net change of momentum in the combined system of Earth-rocket or Earth-helicopter.

You'd accomplish more by moving all that weight to Rhode Island in the first place. The planet's center of gravity would change ever so slightly, inducing precession as it found a new equilibrium along its axis of rotation. Not much precession of course, but we measure similar effects when earthquakes happen.

I mean yeah, the earth would move in some way though.

All those people jumping induce a tiny earthquake, and as you said, earthquakes are capable of altering earth's behavior. (I don't know how, it feels like it should violate some conservation law, only that it's measurable for larger earthquakes so it must be true.) It's just that it would be essentially nothing, and the earth isn't rigid in real life so even then it would probably be even less of an effect than a proton width.

That's true enough. I was just irritated at Randall for not bringing conservation of momentum into it.

It can cause a movement, yes, but it would be so proportionally small that it would just fade into the background noise of all other movement within the Earth system.

And that's assuming a rigid system. The earth being what it is, they may just cause the local plate to bob up and down very slightly, which wouldn't really move the Earth at all.

Whether the earth moves depends on how you define "the earth" as a system, and that choice is more relative to the topic of interest than it initially appears based on introductory physics examples. :P

Here's a video showing just how cursed a double pendulum is.

It's kind of astonishing to watch just how erratic it moves.

Here's another cursed one with a circular bottom half:

No idea what's going on in this demon's contraption:

The real Doppler effect is the ability to get science teachers to make funny noises with their mouths.

Hawaii is a bunch of smaller islands so its total area is less than the drawing makes it seem. It's an optical illusion.
