The beginning of everything. the Big Bang. The thought that the universe was suddenly born and isn't infinite. Up to the center of the 20th century,most scientists thought of the universe as infinite and ageless.
Until Einstein’s theory of relativity gave us a far better understanding of gravity, and Hubble discovered that galaxies are moving aside from each other during a way that matches previous predictions. In 1964, accidentally , cosmic background radiation was discovered, a relic of the first universe, which, along side other observational evidence, made the Big Bang the accepted theory in science.
Since then, improved technology like the Hubble telescope has given us a reasonably good picture of the Big Bang and therefore the structure of the cosmos. Recent observations even seem to suggest that the expansion of the universe is accelerating. But how did this explosion work? How can something come from nothing? Let’s explore what we all know . we will ignore the start part for now.
First of all, the large Bang was not an explosion. it had been all space stretching everywhere all directly . The universe started very, very, very small and quickly expanded to the size of a football. The universe didn’t expand into anything,space was just expanding into itself. The universe cannot expand into anything because the universe has no borders; there's , by definition, no “outside”the universe. The universe is all there's .
During this hot, dense environment, energy manifested itself in particles that existed just for the tiniest glimpses of your time . From gluons, pairs of quarks were created,which destroyed each other , perhaps after giving off more gluons. These found other short-lived quarks to interact with, forming new quark pairs and gluons again. Matter and energy weren't just theoretically equivalent, it had been so hot they were practically the same stuff.
Somewhere around this point , matter won over antimatter. Today, we’re left with almost all matter and nearly no antimatter in the least . Somehow, one billion and one matter particles were formed for each one billion particles of antimatter. rather than one massive ultimate force in the universe, there have been now several refined versions of it acting under different rules.
By now the universe has stretched to a billion kilometers in diameter, which results in a decrease in temperature. The cycle of quarks being born and converted back to energy suddenly stops. From now on, we work with what we've . Quarks begin forming new particles,hadrons, like protons and neutrons.
There are many, many combinations of quarks which will form all kinds of hadrons, but only only a few are reasonably stable for any length of your time . Please take a flash to understand that by now, just one second has passed since the start of everything. The universe, which has grown to one hundred billion kilometers, is now cold enough to permit most of the neutrons to decay into protons and form the primary atom, hydrogen.
Imagine the universe at now as an extremely hot soup, ten billion degrees Celsius, filled with countless particles and energy. Over subsequent jiffy , things cooled and settled down in no time . Atoms formed out of hadrons and electrons, making for a stable and electrically neutral environment. Some call this era the Dark Age,because there have been no stars and therefore the hydrogen gas didn’t allow visible light to maneuver around.
But what’s the meaning of light ,anyway, when there’s nothing alive yet that would have eyes? When the hydrogen gas clumped together after many years and gravity put it under great pressure, stars and galaxies began to make . Their radiation dissolved the stable hydrogen gas into a plasma that also permeates the universe today and allows light to pass.
Finally, there was light! Okay, but what about the part we didn’t talk about? What happened right at the beginning? This part are often defined because the explosion . We don’t know in the least what happened here. At now , our tools break down. Natural laws stop making sense,time itself becomes wibbly-wobbly.
To know what happened here,we need a theory that unifies Einstein’s relativity and quantum mechanics, something countless scientists are performing on immediately . But this leaves us with lots of unanswered questions. Were there universes before our own?
Is that this the primary and only universe? What started the large Bang, or did it just occur naturally, supported laws we don’t understand yet? We don’t know, and perhaps we never will. But what we do know is that the universe as we all know it started here and gave birth to particles, galaxies,stars, the Earth, and you. Since were ourselves are made from dead stars, we aren't break away the universe; we are a part of it. you'll even say that we are theuniverse’s way of experiencing itself.
So, let’s keep it up experiencing it, until there are not any more inquiries to ask.
