Crustaceans have two pairs of antenne, which can be found on the first two segments of the head. These antenna are often used as sensory units, but can also be used for things such as swimming.
In comparison to the world we're familiar with, very, very empty. Consider this: someday M31 in Andromeda and our galaxy, the Milky Way, will smash into each other. Though each has over 100 billion stars and possibly a trillion planets, there's a better-than-even chance not a single pair of worlds will collide; things are that spread out. Moreover, that's the space WITHIN the galaxies; the INTERgalactic space is even thinner than that.

For an extra pair, yes, but for your main pair, no. If your feet are at the edge of one size, go one size bigger and that will be your best size. If your toes have an inch of space, pick that size. That will save you some time to grow into them.
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.

It doesn't exactly occupy more space, but it has a different shape to a bond pair. In a bond pair we have two positive nuclei, with most of the density of the bonding electron pair between the atoms. The outer nucleus attracts the bond pair outwards from the central atom. In a lone pair there is only the central atom to attract the electrons, so they are pulled in more than the bond pair, producing a fatter, squatter shape. This means that more of the electron density is near the central atom than with a bond pair, which makes it more effective at repelling the other electron pairs. Thus there is a difference in the amount of repulsion between different sorts of pair, meaning that he angles between them are different too, in the order, from greatest to least, lone pair-lone pair, lone pair-bond pair, bond pair-bond pair.
It is a pair of integers, separated by a space.
