I am bored at work and this is what I do in all my free time if i’m not reading the Chemistry Textbook…
THE UNRELIABLE AND MANY-TIMES REGURGITATED SUMMER OF HOW THE UNIVERSE CAME TO BE
To my general knowledge with the help of many unreliable sites, I have summarized or otherwise “dumbed-down” the events which lead to the very existence of our universe – mostly the formation of nucleons and atoms.
So – We begin 13.8 billion years ago where a small singularity rapidly (and I mean rapidly) expanded into what we know as the universe and continues to expand today.
Of course, it didn’t just suddenly birth our planets, the sun, and an infinite amount of other galaxies in this one expansion. It started with hot plasma. The plasma we are talking about is not the lava plasma stuff, it’s actually atoms without electrons – essentially ions, very small and quick lived substance that resulted in cooling – Y’know, because the universe is big and all and the heat form it was pretty much sucked out of it and distributed around.
Then, a WHOPPING 10^-12 seconds after the Big Bang, the cooling of the plasma triggered the formation of the substances: QUARKS. Look up the details if your interested because I didn’t.
** At this point, the universe is freezing because there is not enough heat to keep the universe/space at a comfortable temperature.
And you guessed it! The Quarks combined into groups of three Quarks called Baryons. And more of that all combined and now we have protons and neutrons. Remember that protons and neutrons are called nucleons that when together form nucleus?
Nucleosynthesis happened and the first, and definitely not the last, nucleus was formed.
Electrons like nucleuses…
SO, now we are three minutes after the Big Bang happened and we have the first atom: HYDROGEN! The universe consists of 90% Hydrogen.
Now there is Helium.
Eventually, the other elements of the periodic table are formed when different combinations of nucleon numbers and electrons join.
4.5 billions AGO/ which is 9.3 billions years after the Big Bang, the sun was born as a great, energy releasing star of Hydrogen and Helium. It was thought that a cluster of similar smaller stars of the same age and composition fused to create one big star, the sun.
After the sun’s birth, the strong and orbital rotations of gravity pulled debris and elements together creating the planets.
That brings me to the conclusion of my very incorrect but easy to follow thoughts on how the universe and atoms came to be. Hopefully, you know the rest.
