I would imagine there would be no earth.

It was stated that the moon was close enough when it was created, that it was 10 times it's size (due to proximity)

Pretty crazy. Being that close I'm sure the oceans were crazy.

I'm sure there would be an earth, but vastly different.

I reread the OP.... heres a contender.


Atoms are 99.999999999999% empty space. meaning that all matter making up the entire human race could fit into a sugar cube.

Here is an easy one. If you shoot a gun and drop a bullet both the bullet you shot and dropped will hit the ground at the same time. Duhhhhh

What do you mean by 'empty space'?

Remember, nature abhors a vacuum.

Empty space being absent of any matter.

I can remember reading a size comparison of an atom that explained it this way the nucleus of an atom would be the size of a couch ( which contains 99.9% of the mass.) The electrons that encircle it would be doing so at the distance of a large city block and the size of a marble. The inbetween space is empty or free space of which given the complexities of quantum level mechanics is yet unknown. Nature abhors a vacuum my very well be the case indeed.

You're ignoring sub-atomic particles and quarks, which are assumed to be matter.

You can put a match that is on fire into a bucket of gasoline that has been cooled down and the match will not cause the bucket of gasoline to catch on fire and will actually put the match out as it goes into the gasoline.

Also, there is a such thing as a no slip boundary layer condition. This means that at a microscopic distance from the surface of something such as a pipe, the fluid it is in contact with actually is not moving. This is why there is dust on the blades of fans even though the blades are continually moving.

Nothing ever really touches anything.....Rub your hands together and its the electrons around the atoms of your skin that are touching and generating the heat.

If you were to light a match on Titan, Saturn's most popular moon, the whole moon would go up in flames...if only there were oxygen in the atmosphere.
