Curiosity about the Universe leads to more unanswered questions about its nature, origin, and existence. Inquiries about starting points result in inquiries about existence itself, culminating in the question of how something arises from nothing. Science indicates that the Universe, which began with a hot Big Bang 13.8 billion years ago, is governed by General Relativity and dominated by dark energy and dark matter. Today, the Universe contains galaxies, stars, planets, and intelligent life, all of which arose through cosmic evolution.
The more curious we get about the great cosmic unknowns, the more unanswered questions our investigations of the Universe will reveal. Inquiring about the nature of anything - where it is, where it came from, and how it came to be - will inevitably lead you to the same great mysteries: about the ultimate nature and origin of the Universe and everything in it.
Today, when we look out at the Universe, the full suite of observations we've collected, even with the known uncertainties taken into account, all point towards a remarkably consistent picture. Our Universe is made of matter (rather than antimatter) and began - at least, as we know it - with a hot Big Bang some 13.8 billion years ago.
