Yes.
To be more exact, it is "space" within the "observed universe" that is expanding.
A confusing fact is that many astronomers believe the universe as a whole may already be infinite in size. This doesn't stop them saying the observable universe is still expanding.
"Infinity" is a tricky idea.
No, the solar system is just the same give to the system of planets which orbit the Sun. There are millions of similar systems in this galaxy and there are millions of galaxies in the universe.
They continue to grow in their 20 year lifespan each year getting bigger
If one thinks about the possible states of the Universe, there are three possible situations - it's expanding, it's standing still or it's contracting. Einstein made, what he described, as his biggest blunder by assuming it stood still - as he said, a few seconds thought should have shown that a stationary Universe will immediately start to collapse under gravity. Hubble observed that objects in the Universe are moving away from Earth and that more distant objects are moving faster. The explanation of this comes from General Relativity and is interpreted as an expanding Universe, however it takes a few minutes calculation to realise that as we think about the further reaches of space, it is expanding at rates far greater than the speed of light (c). This seems to contradict Special Relativity and is getting a bit beyond my knowledge(!), but its solved by not thinking of the edge of the Universe zooming along well beyond c, it's not zooming into anything, it's simply getting bigger. So, yes it is expanding, and at enourmous (by our standards) rates.
The motto of Incredible Universe is 'If it's not in the Universe, it doesn't exist!'.
Yes. Galaxy clusters are clusters of galaxies and therefore larger than individual galaxies. Superclusters are clusters of galaxy clusters and so are larger then galaxy clusters. Filaments are collections of superclusters and are the largest known structures in the universe.
Yes, it is expanding.
The universe is getting bigger because more and more objects are being discovered. The earth will never get any larger.
A universe is bigger than a planet.
A universe is bigger than an organism.

The Universe is bigger. The Universe encompasses everything we know; it isn't known whether there are other universes.
It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.

A planet is bigger than a university. You probably meant a universe and a universe is bigger than a planet.
