Comment 8 by Rothron the Wise :

I don't think you're right about that. My computer came with a built-in screensaver where it's like all the stars are flying towards you. I just put it on and I definitely counted more than 2000 of them.

Are you joking? 2000 might be a little low, but you can't compare the simple starfield screensaver to something that involves simulating gravity.

In a gravity simulation complexity scales as the square of the number of bodies in the simulation, because the gravity of every body needs to interact with the gravity of every other body.

This means that the difference in complexity between a 10 body simulation and a 10000 body simulation is 6 orders of magnitude.

Humor is often wasted here...

PS: I thought it was funny.
