"Left: All the water in the world (1.4087 billion cubic kilometres of it) including sea water, ice, lakes, rivers, ground water, clouds, etc. Right: All the air in the atmosphere (5140 trillion tonnes of it) gathered into a ball at sea-level density. Shown on the same scale as the Earth." |

Oh come on. You are regressing!
But I demand to see a pair of hands ripping apart the ozone layer, goatse-style, as an accompaniment.

I love how you remembered the wedding ring detail! A+.

And yet the world is 70% covered in water.
Funny that Greenland and Iceland are still white on the left Earth.
"Sea level density" is pretty contrived in this context... it'd be interesting if somebody smarter than me figured out what that much water would look like deposited in a single place in space. Would it just be a giant drop which would deform and gradually splash away? Would it have enough gravity to maintain some kind of spherical shape?
mass, not gravity, obviously.
Would it have enough gravity to maintain some kind of spherical shape?
Yes. Even if it didn't, surface tension would hold it together.
It would stick together as a sphere if undisturbed from surface tension, but I guess I was thinking about swimming in it... or whatever. I imagine that the escape velocity would be pretty low.
At the surface, a 1lb weight on Earth would weigh 0.02lb. 150lb here, 3lb there.
No. If it was exposed to vacuum (as it would be if deposited in some place in space) it would boil until its temperature went low enough to freeze. It would not have enough gravity to hold an atmosphere.
It would make a very clean comet. How long it would last would depend on how far it was from a star.
deform and gradually splash away
That which did not vaporize instantly from being in hard vacuum would quickly freeze into an giant icy comet.
Just out of curiosity, what do you think of the new NIN album(s)?

Yup, I'm really liking it as well.

Everywhere l look, something reminds me of her.
the only thing i could think of was planetary boobies....*face-palm*

Why measure water by volume and air by weight, I wonder?
Nice. Very motherly ;-).
