Origin of the universe essay
Many theories have been given, but the main theories to this day are the ones of creationism and evolution.
The story is undoubtedly a long journey. Finally, we stop at about 15 billion years after the big bang, possibly our present day, and what do we have? Most scientists agree that there was a beginning but there is a lot of speculation of how it the universe actually started.
From a dense, hot ball of gas, radiation and subatomic particles.
This is how our Sun originated about 4. The Dreamtime explains how everything was created not only the universe and also explains the rebirth of earth.
Origin of the universe summary
This is probably the greatest discovery imaginable; however, the universe still seems to be a very controversial subject. The Universe is all of spacetime and everything that exists therein, including all planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy. Several answers have been proposed to address this fundamental question, but none has been proven—and even adequately testing them has proven to be a formidable challenge. No matter whether you're looking from Earth or from an alien planet billions of miles away, all other galaxies are moving away from you as space expands. The laws of physics under such a condition are not known. The Big Bang Theory The story is told, by such modern-day astrophysical and mathematical prophets as Stephen Hawking, Roger Penrose, and others, of a time when the universe was nothing like it is now— galaxies had not formed, planets were not in existence, even the elements which we recognize so easily today were not even in their stages of infancy. If matter is continuously created everywhere, then the average age of stars in any section of the universe should be the same. The Big Bang model and the Steady State model are the two that were constructed. From a dense, hot ball of gas, radiation and subatomic particles. Aristotle based his model of the universe on Pythagorean theory which described the Earth as a sphere. My first point is to question where were these three gases. But could this make sense? Instead, it comes from laboratory experiments.
The big-bang theory predicted this remnant radiation, which now glows at a temperature just 3 degrees above absolute zero. They argue that gravity from huge, undetected objects in space clouds of cold, dark matter we can't see with telescopes, or so-called cosmic strings attracts matter into clumps.
The universe, at this point, is now the size of an orange.
