Which is bigger? (Astrophysics)

[Whack-a-Mole]

As a way to concieve of the relative size of an atom, I’ve always found this example useful:

If you take a glass of water and throw it in the ocean, then wait, say 30 years (or whatever it takes) for the water from that glass to disperse through all the oceans. If you go to the ocean again and take a glass of ocean water, it will probably have a molecule of water that was in the original glass. That’s because there are more water molecules in a glass of water, than there are glasses of water in all of the oceans.

Here’s a similar example I got in another thread that is interesting (sorry if I Godwinized this thread ;)).

Yes. With every breath you take, on average you inhale four molecules that Hitler exhaled in his last breath.
