How did the universe come to be?

if you're going to say "god" please don't bother answering, I believe that all life forms came about through evolution, but how did the universe itself get here? i've heard about this big bang theory but i'm not really sure what it is, if anyone has any enlightenment about this, please share it with me, thank you.

    This is a huge subject, covering a multitude of scientific disciplines.

    First off, the processes that lead from the original Big Bang to life on Earth are known in pretty good detail.

    * (-infinity) -> (Big Bang t0 : 12 billion years ago)

    'Prior' to the Big Bang (which is not a useful descriptive term) only hypotheses exist - but they're good ones. They involve M-theory, branes, superstrings, a 10-D multiverse and similar weird stuff that is only thought to exist by some. Watch this space.

    * (Big Bang t0) -> (Big Bang+(1e(-43)s) : 12 billion years ago)

    The Instant of the Big Bang itself is also closed to 'normal' mathematical exploration at the moment. During this period - which is called a Planck Time, the smallest unit of time - the universe was less than a Plank Unit (the smallest unit of space) in size. All the math science has is broken for the duration: some numbers go to zero, others fly off to infinity. We haven't developed the tools to describe the situation.

    But among the popular hypotheses being worked on is one in which the 'brane' (an N-dimensional sheet on which all normal particles exist as tiny loops of 'string') in which our universe was to exist received a massive injection of energy from a nearby explosion - caused by another brane colliding with an anti-brane.

    This energy spill-over appears to have begun at a point, and was great enough to eventually become the entire universe as we see it today.

    * (Big Bang+(1e(-43)s)) -> 5 Billion years ago.

    Things improve mathematically after the first Planck instant: the zeroes and infinities become real numbers, and it's possible to find figures for temperature, mass and velocity. Observations confirm these figures.

    From a point (ten-to-the-minus-43) seconds after the BB until now, the cosmological model hangs together well, and predicts things like the hydrogen/helium ratio and the Cosmic Microwave Background accurately. Matter condenses, stars form, galaxies form, planets form. Earth accretes, along with the rest of the Solar System, out of the dust-cloud spewed out by at least three nearby supernovae. This combination of physics, cosmogony, cosmology and math get us up to a warm, wet, anaerobic Earth.

    * 5 billion years ago -> 4.5 billion years ago

    Then there's a period of Abiogenesis, which can't be verified at present because billion-year experiments are hard to do. The biochemistry is sound, however, and each new set of data is yielding better results for the formation of biochemical goo on the planet, the first Replicator, and the first primitive cells.

    * 4.5 billion years ago -> Now

    Once you have a Replicator, evolution takes over, and builds up complexity and variation over the subsequent billions of years until we get to now - where the planet's dominant animals are beetles or bacteria, and the dominant species is grass.

    The closest thing you're going to get is the Big Bang theory. Technically it isn't about the creation of anything, but it is the explanation for how the universe as it currently exists was formed.

    However it's a very complex theory, which those of us without physics degrees have a hard enough time understanding, let alone explaining. You can find some good information (and a lot of bullshit) on the Internet, or read one of the many books that attempts to explain the concept simply. Hawking's 'A Brief History of Time' is an excellent example.

    In other words, you do not want the correct answer. How can anyone answer your question intelligently? The big bang theory is that something very small (compressed energy) exploded. It could very well be true, but how does that answer your question? You still got an effect without a cause. There are some very good answers out there without actually using the word "god", but it would probably mean about the same thing in effect. Would prime mover as an omnipotent being offend you? I will go no further out of respect for your wishes.

    The vast majority of what we call "the universe" is empty space. It has been here all along. Matter/mass seems to have appeared at a point source around 13 3/4 billion years ago from which it is expanding in all directions. This is called the "big bang". "Echos" of this event have been seen since the late thirties and the dawn of radio astronomy. This after-glow is called the Casmic Bachground Radiation. Astronomers/Astro-physicists discovered that in every direction, they could detect minute amounts of electro-magnetic radiation in the microwave band. It is significantly red-shifted and the oldest "light" that we can see. Life is a complex self-replicating relationship between matter and energy. The best scientific answer is that life developed in an advantageous environment around 4 1/2 billion years ago and has evolved into its present form over time. The alternative theory of life involves magic and I won't go into it here.

    You know that picture of the Earth from space? You can't even see the cities let alone the people in them they're so small. If we're nothing but little specks on the surface of a ball, how do you expect on or two of the specks is going to have the ability to determine how the whole Universe came about?

    We may NEVER know the origin of the entire, vast Universe, I know that's a bitter pill to swallow for curious, inquisitive little humans, but ... c'est la vie.

    We are supposed to have been put into motion by the big bang that had everything in the universe in one place, when this happened it set in motion an expansion that is still speeding up. Eventually the universe will spread out so far that the planets will spread apart and we will become a dead frozen globe. and entire universe will be dead .

    However you want it to. Big bang is just a theory. Creation wasn't seen. For as far we know a big rabbit could've crapped the universe out of his ***. I think this is just one of those questions you just have to choose the answer for yourself, based on your own reasoning. Remember, think logically. Your logic is different from the people around you, so if you get a different oppinion, or the same one, just go with it!

    Do u want the answer from the bible or from other religions or from science?

    All those answers are metaphors and meant to be followed to be a good religious person.

    There should always be a platform for a discourse or discussion.

    The platform here is - matter converts to energy and energy converts to matter.

    Look at the bombs.

    The universe and matter are indestructible and they always existed.

    Now u can develop the answer unless u find a better bible.

    ok before the creation of anything there was this little light, very small, this, however, expanded, forming the universe, its expansion was unfinitive, however, while its expansion, stars started to form planets, then on planet Earth, life was created.

    Some people have the belief that god doesn't exist and that science created everyting, other think that god created everything, but there is another simple explanation for this, god created science and science created god.

    All matter was here since the begining of time. It was all very close together and then it exploded and extended outward int the universe things began to form together andhere we are today after many years of evolution and such
