As I sit at the garden side just outside my house during a breezy night, I wondered about life. Life as a whole – how it was created and how humans were together. A ‘Big Bang’ or thought hit my head.
The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Astronomers make observations to develop workable theories of how the Universe came to be. The underpinnings of the Big Bang theory include Albert Einstein’s general theory of relativity along with standard theories of fundamental particles.
According to the standard theory, our universe sprang into existence as “singularity” around 13.7 billion years ago. What is a “singularity” and where does it come from? Well, to be honest, we don’t know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of “black holes.” Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called “singularities.” Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something – a singularity. Where did it come from? We don’t know. Why did it appear? We don’t know.
After its initial appearance, it apparently inflated (the “Big Bang”), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out of nowhere for reasons unknown. This is the Big Bang theory. Explained by http://www.big-bang-theory.com/.
Thanks to the most popular theory of the creation of the universe, the Bing Bang Theory caught my attention the most. I learned that we, humans, are all stardust. We are star stuff, PONDERING the stars.
According to Simon Worrall from National Geographic, all the material in our bodies originates with that residual stardust, and it finds its way into plants, and from there into the nutrients that we need for everything we do—think, move, grow. And every few years the bulk of our bodies are newly created.
“We are a way for the universe to know itself. Some part of our being knows this is where we came from. We long to return. And we can, because the cosmos is also within us. We’re made of star stuff,” Sagan famously stated in one episode stated Remy Melina on October 12, 2010 on Live Science.
Astronomers and scientists are still figuring out how the universe first started. Theories are expanding just as our universe is expanding. The closest theory we have to understanding the universe as a whole is the Big Bang Theory.
Thanks to Piktochart, I was able to create a Primer Poster which involves my insights after watching a movie called, “History of the world in 2 hours”.
