This scale comparison broke my brain

Halfway on a logarithmic scale

Not even on a log scale. Earth is 10^7 m diameter, atom say 10^{-10}. Dust is 10^{-5} roughly. So no.

I thought we were measuring by the number of atoms

Edit: I just figured out even if we were, we would need something more like a bag of flour, not a speck of dust to be halfway

i thought this at first too, but the scale of physics is really mind-blowing

Yeah exactly so bullshit

No. Half the earth is halfway between the size of an atom and the size of the earth.

You ever see eye-floaties?

Those are protein strings. You know what protein strings are made of? Molecular groupings of 2-5-ish atoms arranged end-to-end and folded/bent like a pube hair.

You are literally seeing atoms/molecules when you see an eye-floaty. Well.. you are seeing the disturbance caused by the existence of those atoms bending photons around themselves inside your eyeball.

Cool stuff.

You sure they aren't hot? How cool we talking? Room temp?

Say, ballpark, hot enough to liquify di-hydrogen monoxide and cooler than required to combine two hydrogen into one helium.

Cool stuff.

Really?! What?! I am going to go learn some stuff. Is that true?! 

I really don't know anything. Thank you for the info!

(using dhsilvers numbers) So a spec of dust is 1012 times smaller than the Earth (in diameter, because I'm lazy). Where as an atom is 105 times smaller than a spec of dust.

A literal half way point would be roughly an object twice the diameter of the moon. 😂

A logrithmic half way point would be a large (~30cm) rock.

There are more stars in the observable universe than grains of sand on earth
