Astronomy and the Universe
Its amazing how colossal the universe is and its expanding as we speak, scientists and astronomers have discovered new moons, comets, meteorites, art galaxies such as the helix and eagle nebulas, which are formed when the stars die, and extraterrestrial objects entering the universe and mysteriously targeting earth, Jupiter and other planets in our solar system, galaxies such as Milky Way, Andromeda, Sagittarius Little Red dwarf and many more have merged together to create clusters of stars dispersing out into Space.
Without the comet, meteorite and galaxy collisions, the great Primeval Triassic extinction which took place around 2500 billion years ago, would not have occurred wiping out all plants, living life on earth and therefore paved way for the dinosaurs to begin life, end with a meteoroid destroying their existence and bring about the birth of mankind.

From thousands of years mankind has endeavored to study as much as possible about the universe, but there are still a lot of things that are unknown. There are lot of things that we know and more than that, there a lot of things that we do not know about our universe. Science has progressed in the field of astronomy; we have learned a lot and are amazed and confused of whatever we have learnt. As the technology is progressing, more and more the learning is increasing.
Some of the interesting facts about the universe are described below.

In the infinite beginning was the vacuum energy (a quantum state of energy and matter, even if the matter is virtual). The vacuum energy resided in space and time (or space-time, post relativity theory). Now why ‘in the infinite beginning’? It eliminates the awkward, nagging and very annoying philosophical question of ‘what came before that?’ Its neigh near impossible to avoid asking that because one just can’t come to terms with a finite beginning to everything. It’s obvious in a common sense sort of way that no matter how far back you go, something came before that.
From the vacuum energy (which again is a quantum phenomenon often termed vacuum or quantum fluctuations, the quantum jitters or quantum foam), at least one macro universe arose. This is theoretically possible (see references at the end) although I strongly suspect it has an awful lot to do with the quantum mantra that ‘if it’s not forbidden, it’s compulsory’ – at least if you’re willing to wait long enough. Of course maybe more than one universe arose from the vacuum energy. The more the merrier!
