How Did The Universe Begin And How Will It End?

3. What is the Big Bang, and what does it say about the age of the universe?

The currently accepted model of the Big Bang is "that the the universe is not static but is expanding and that the expansion began in an incredibly hot, dense Big Bang approximately 13.72 billion years ago" (Krause, 2012, p. 25). This hot, dense bit of matter was only a few millimeters across and contained all of the matter and energy that makes up our universe and as it expanded, it cooled and over the billions of years of existence the universe settled into its current state.

We are not quite sure exactly how it happened or even how long it took to happen. According to www. Space.com it underwent an incredible growth spurt and doubled in size at least 90 times. This marks the beginning of an extraordinary set of circumstances that created a perfect storm. It was a chaotic set of circumstances the temperature cooled than heated then combined and light appeared and was eventually followed by complete darkness. This light is detectable today and can be researched which will hopefully lead to answers that we have been wanting to answer for many years. Nearly 400 million years after our universe made its appearance in this dramatic and chaotic performance it began to come out of its dark ages. This phase of our universe lasted for a very long time and during this time our very first stars and galaxies appeared. The birth of our Solar System happened approximately after our universe turned 4.6 billion years old. It is believed to have been formed out of a “giant, rotating cloud of gas and dust known as the nebula.” In 1960 dark matter was discovered and remain one of the biggest unanswered questions today. Earth made its entrance approximately 4.54 billion years ago. At its beginning it wouldn’t have been able to be inhabited by humans. Volcanic activity was the norm and at one point there was a collision with another body that is thought

Throughout, the book, The Accidental Universe, Alan Lightman the author of the book discusses a number of ideas ranging from, how the world came to be, to the multiverse, as well as other various ideas and his thoughts on them. Consistently throughout the book, Lightman was wishy-washy and it appeared he was trying to please both Atheists, as well as religious people. However, his key idea stays prevalent throughout the entirety of the book. The idea being that this universe came to fruition accidentally, out of nothing.

It was wound up and is constantly winding down ultimately to or demise. The second law of thermodynamics is before us in a form of a big question. Who wound up the universe? The only plausible answer is God.

There have been many theories concerning what the universe looks like, how it became this way, and where it is going. The most popular theory that people hold today is that the universe began when all the matter ever present in the universe was contained in a tiny speck and that spec exploded. This is known as the Big Bang. This theory has developed a great deal since it was first conceptualized and continues to evolve today. Many different scientists have had a hand in this.

Developed over many years and by many people, the theory states that about 15 billion years ago the universe was compressed into an infinitely small space, known as the primordial atom. It exploded in a sudden burst of energy and created a small,

When space and the universe began, the existence of time also began. This theory is well-known as the Big Bang Theory. About fifteen billion years ago, the universe was comprised of very hot compressed gas, as a fireball. This is contrary to the idea of the universe beginning as a lump of matter somewhere in the void of space. Matter was created as a result of the Big Bang.

The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density. In the big bang, the material exploded outward into the formation of matter that we see today. Shortly after this event everything in the universe was very dense and very hot. It was only until 500,000

The universe emerged billions of years ago, but more recently chemically complexity formed. Everything was formed from the first common elements, hydrogen and helium. With time these elements became more complex and formed the solar system. Once the solar system was created, life began to form.

"In the beginning, there nothing. A giant black void of nothing. It was called the Chasm. Nothing moved, nothing changed, it was a static abyss of emptiness. The Chasm wasn't evil, but it was good either.

At its easiest form, it talks about the universe as we know it starting with a small thing then inflating over the next 13.8 billion years to the cosmos that we know today. In the first second after the universe began, the temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius), according to NASA. The cosmos contained a fundamental particles such as neutrons, electrons and protons. combined as the universe got cooler This relates to the unit that we talked about which is how the universe was made and the forming of it (Howell, Elizabeth.

The solar system, the Sun, and the Moon are formed from particles coming together and forming the Planets and Stars. It is theorized that the Universe was formed from something called the Big Bang. Scientists think that the Universe and everything in it was formed from a Big Bang that was caused from a small, very dense, and very high-temperature area in space. Because of how Dense and Hot the area was, it exploded and expanded into the Universe. We know that the Sun, Moon, and Solar System were formed when particles came together to make the planets and stars, but we don’t know for sure if the Big Bang was how the Universe was formed.

Astronomers believed the Universe was created about 14 billion years ago. During that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead, and it was insanely hot and dense. Out of nowhere this little bubble started expanding. This expansion created what we know as the Universe. In such little time the Universe went from the size of an atom to the ginormous galaxy we have that is continuously growing.

Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and caused a large cloud of dust and gas to collapse in on itself. The hot, central part of the cloud became the sun, while some smaller pieces formed around it and became the planets. Other fragments became asteroids and comets,
