Origin of the Universe

Origin of universe

The universe is everything that exists, everything that has existed and everything that will exist. The universe is all of time, space and its contents. The universe includes things such as moons, galaxies, planets, stars, minor planets, the contents of intergalactic space, and all energy and matter. The universe consists of spacetime, forms of energy (including electromagnetic radiation), and the physical laws that relate to them. The universe ecompasses all of life and all of history. Some philosophers and scientist suggest that it ecompasses ideas such as logic and mathematics. The size of the universe is unknown, no one can seem to find the beginning. The universe is thought to be finite or infinite space-time continuum in which all matter and energy exist. The universe is ever-expanding outward so it has no form, size or shape. Scientist don't know when the universe will end, they're not even sure if it will end at all. A belgian priest named Georges Lemaitre came up with the big bang theory in the 1920’s when he theorized that space began from a single primordial atom. The most popular theory of our universe origin centers on a cosmic cataclysm in all of history- the big bang. This theory was born from the observation that other galaxies are moving away from our own at great speed, in all directions, as if they all had been propelled by an explosive force. Before the big bang, scientist believe that the entire enormousness of the observable universe, including all of its radiation and matter, that was compressed into a hot, dense mass just a few millimeters across. Scientist believe that the universe was created from an enormous explosion of light and energy known as the ‘big bang’.The universe began 13.6 billion years ago when there was a big bang. All the mass in the universe was compressed into a single point of infinite density. When the big bang started, this matter was heated to very
