27. Solidity is...

what keeps everything from happening at the same place.

Although when my kids were small it seemed like everything in the neighborhood always happened at my place. But that's probably because the other kids' parents were more repulsive. In the force field sense, not in the personal hygiene sense. I mean the other parents weren't actually repulsive, it's just that they tended to apply more force against children who congregated at their houses. Not that they actually applied physical force, mind you. but that... Oh, never mind. I'll stop now while I'm still ahead. Or at least before I get any further behind.

No. That "empty" space is pervaded by fields, such as the EM field ... eppur_se_muova Sep 2012 #10

Thanks for the info. I like the magnet analogy, because it relatable. ZombieHorde Sep 2012 #12

Exactly. Igel Sep 2012 #13

That is really interesting to me. Thanks for posting. nt ZombieHorde Sep 2012 #14

It's actually electron degeneracy pressure that keeps atoms from collapsing... DreamGypsy Sep 2012 #17

Well, that's what keeps the electrons in atoms from collapsing inward ... eppur_se_muova Sep 2012 #19

DAMMIT, you beat me to the magnet analogy! Odin2005 Sep 2012 #24

Funny, but the analogy of repulsive parents seems to fit. nt ZombieHorde Sep 2012 #33

Sorry, but atoms are not "mostly empty". DetlefK Sep 2012 #28

By "subjective," I did not mean imaginary, I meant subjective to our size. ZombieHorde Sep 2012 #31

Then yes. DetlefK Sep 2012 #39

How do you know atoms are mostly empty space except through perception? GodlessBiker Sep 2012 #29

Well, I have not personally perceived nothing about individual atoms, only clumps of atoms. ZombieHorde Sep 2012 #32

Rutherford's gold foil experiment is how we found out that atoms are mostly empty space johnd83 Sep 2012 #36

I learned something! nt ZombieHorde Sep 2012 #35

Being that we all experience the phenomenon of solidity the same, then gtar100 Sep 2012 #37

I was thinking subjective due to our size. ZombieHorde Sep 2012 #38
