How was the very first particle of matter came into being? Do we really need a God to make this universe ? After doing a lot of hardwork i came to conclude the following: Firstly, a lot of people ask what was before the Big Bang. Thats a relatively easy one to answer; nothing. No matter, no energy, nothing but nothing. Not even a vacuum. There wasnt even any space for something to occupy, no time for it to exist in. There wasnt a before, before. So what led from this nothing to, well, everything? The original Big Bang suggested that everything, every single piece of matter that now exists, was originally scrunched up into a point so small it stops having any dimensions at all, a singularity. In cases like this, some suggested all that matter came from a previous, collapsed universe. Nowadays, scientists use terms like a quantum fluctuation resulting in a particle of negative pressure vacuum energy. Which to me sounds like something from Star Trek, but apparently its perfectly acceptable to allow the universe to spontaneously generate in this way, and its backed up by empirical tests. Either way, you now have your singularity; either a zero-event point containing everything, or one containing nothing. Your mileage may vary, but not by as much as youd imagine. At this point, you stand well back. Do not attempt to return to a lit singularity. Within a fraction of a second thats too small for the human mind to begin to envision comfortably, theres a blinding flash, and an outrushing of a staggering size and velocity. In this instant, the building blocks of energy, gravity, space and time are flung out. Temperatures are around 10 billion degrees celsius. As it expands, things start to gradually cool down, cohering into subelementary particles, and eventually matter. Within three minutes, the light show is over its spectacular stage, and 98% of the matter that will ever exist, exists. After all the excitement, its merely a matter of waiting for things to settle down, and waiting for all the helium and hydrogen to clump together into stars, which in turn eventually supernova and produce just about every heavy element above lithium on the periodic table, which then begin to form new star systems with actual planets. Its all a bit Newtonian by this point, and not nearly as exciting to watch; if you wait around about eleven and a half billion years, important things like tea and sponge cake and pocket-sprung mattresses find ways to come into being. Oh, and life, also. Theres a lot of evidence to back up the theories behind the big bang so far. Perhaps most notably, the background radiation from the event itself, which fills the night sky in all directions, and reaches the earth in the form of redshifted microwave radiation. Youve all actually witnessed this; if you turn on a TV and tune it to a dead station, about 1% of the hissing static you see will be these microwaves. As Bill Bryson says, if you ever complain theres nothing on TV, you can always sit and watch the birth of the universe. Theres also a lot of minor inconsistencies in the theory, which will only get a brief mention because frankly, theyre way too scientific. Scientists are still working out the fine details and adding to the theory; its all rather cutting edge considering its talking about something which happened so long ago. And there you have it. A reasonable explanation as to how everything came about without anyone having to poke it to make sure it works, or say let there be light. Its quite possible a supreme being could do exactly the same and create the singularity needed, but theres no necessity for there to be such a being.
