The Beginning of Everything — The Big Bang


The beginning of everything. The Big Bang. The idea that the universe was suddenly
born and is not infinite. Up to the middle of the 20th century,
most scientists thought of the universe as infinite and ageless. Until Einstein’s theory of relativity gave
us a better understanding of gravity, and Edwin Hubble discovered that galaxies
are moving apart from one another in a way that fits previous predictions. In 1964, by accident, cosmic background
radiation was discovered, a relic of the early universe, which, together with other observational
evidence, made the Big Bang the accepted theory in science. Since then, improved technology like the
Hubble telescope has given us a pretty good picture of the
Big Bang and the structure of the cosmos. Recent observations even seem to suggest
that the expansion of the universe is accelerating. But how did this Big Bang work? How can something come from nothing? Let’s explore what we know. We can ignore the beginning part
for now. First of all, the Big Bang was not
an explosion. It was all space stretching
everywhere all at once. 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 is, by definition, no “outside”
the universe. The universe is all there is. In this hot, dense environment, energy
manifested itself in particles that existed only for the
tiniest glimpses of time.>From gluons, pairs of quarks were created,
which destroyed one another, 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 were not just
theoretically equivalent, it was so hot they were practically
the same stuff. Somewhere around this time, matter
won over antimatter. Today, we’re left with almost all
matter and nearly no antimatter at all. Somehow, one billion and one matter
particles were formed for every one billion particles of
antimatter. Instead of one massive ultimate force
in the universe, there were now several refined versions
of it acting under different rules. By now the universe has stretched to a
billion kilometers in diameter, which leads to 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 have. Quarks begin forming new particles,
hadrons, like protons and neutrons. There are many, many combinations of
quarks that can form all sorts of hadrons, but only very few are reasonably stable
for any length of time. Please take a moment to appreciate that
by now, only one second has passed since the beginning of everything. The universe, which has grown to one
hundred billion kilometers, is now cold enough to allow most of the
neutrons to decay into protons and form the first atom, hydrogen. Imagine the universe at this point as an
extremely hot soup, ten billion degrees Celsius, filled with
countless particles and energy. Over the next few minutes, things cooled
and settled down very fast. Atoms formed out of hadrons and electrons, making for a stable and electrically
neutral environment. Some call this period the Dark Age,
because there were no stars and the hydrogen gas didn’t allow visible
light to move around. But what’s the meaning of visible light,
anyway, when there’s nothing alive yet that could have eyes? When the hydrogen gas clumped together
after millions of years and gravity put it under great pressure, stars
and galaxies began to form. Their radiation dissolved the stable
hydrogen gas into a plasma that still permeates the universe today
and allows visible 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 can be defined as the Big Bang. We don’t know at all what happened here. At this point, our tools break down. Natural laws stop making sense,
time itself becomes wibbly-wobbly. To understand what happened here,
we need a theory that unifies Einstein’s relativity and quantum
mechanics, something countless scientists are working on right now. But this leaves us with lots of
unanswered questions. Were there universes before our own? Is this the first and only universe? What started the Big Bang, or did it
just occur naturally, based on laws we don’t understand yet? We don’t know, and maybe we never will. But what we do know is that the universe
as we know it started here and gave birth to particles, galaxies,
stars, the Earth, and you. Since were ourselves are made of
dead stars, we are not separate from the universe; we are part of it. You could even say that we are the
universe’s way of experiencing itself. So, let’s keep on experiencing it, until
there are no more questions to ask. Subtitles by the Amara.org community

    How could an illiterate man who lived 1400 years have known about the expansion of the universe?

    There are three possibilities to how the universe could end: Big Rip, Big Crunch or Big Chill. NASA recently ruled out the first scenario (No Big Rip; see also: Universe Today). This leaves the universe with only two possible endings: Big Crunch or Big Chill. 

    In the Quran God promises to make the Big Crunch:

    [Quran 7.187] They ask you about the Hour, "When will it come?" Say, "Knowledge of it rests with my Lord. None can reveal its coming except He. It weighs heavily on the heavens and the earth. It will not come upon you except suddenly." They ask you as if you are responsible for it. Say, "Knowledge of it rests with Allah," but most people do not know

    Also after this Big Crunch is over, God promises to recreate those heavens and Earth once more before Judgment Day:

    [Quran 14.48] On the day when Earth will be swapped by another Earth and so will be the heavens; and all (creatures) will resurrect before the One Dominant God.

    [Quran 36.81] Is He not, who created the heavens and the Earth, capable of creating others like them? Yes, indeed! He is the All-Knowing Creator. His command, if He wanted a thing, is that He only says to it, "BE" and it becomes! So glorified is He in whose hands is the dominion of all things, and to Him you shall be returned.

    There are so many unanswerd questions. If space, time and matter did not exist in the beginning when did the big bang happen? ( time did not exist) what was involved in the Big bang? (matter and energy did not exist) and where did it happen? (space did not exist). To believe in the big bang you need to take a lot of things by faith. It's a theory at best. It is not a fact, its a suggestion that you have to take with a grain of salt. To belive nothing existed and then something came into existence all on it own you go against fundamental scientific laws.

Are there other universes? Can humans really do anything noticable compared to the universe? Is there even a universe. Are we the only things alive? Does anything other than humans have concisnes? Are there really atoms? What is concisnes. How was life created? Are characters in tv shows, movies, or video games aware of us? Do they have concisnes? Can we simulate concisnes? Is the universe infinite? What will happen after forever? Will there be another universe? Am i insane?

    There is simply God, because it is impossible that the universe created itself by chance, there is the Creator of the universe. And many atheist scholars place illogical and illogical arguments to assert that there is no god, nor is it possible that this god is born or dies the creator of this universe to forgive the sins of the people, in short …….. This verse explains to you the following: "Say:" He is God, He is one who has not borne and has not been born. Great truth of God.

    So your telling me that reality exploded into existence in the most flagrant display of spontaneous generation in existence despite spontaneous generation being a scientific impossibility? I enjoy your videos. But there are some things taught in schools today that if you look at it with a critical mind you find its just bullshit spit out by pseudo-scientific charlatans. "God cannot possibly exist! It offends my sensitive feelers and goes against my desire to be a piece of shit. So I will 'research' how the universe was not created but instead poofed into existence." charles darwin and those like him are fools.

    the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.[1] This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. This is what the Big Bang is based of of and also makes the Big Bang not true

    I actually don't believe in any of this my theory about God is: god made time so he controls time and not time controls god that means there's nothing that's called begin or end it's maybe just some kinda other system or no system at all maybe god is the whole system who knows.
    we'll never know cuz our brains aren't strong enough to understand cuz if it does that'll mean there is no difference between us and god right? Its all about understanding how to do what god does and replicate it but we can't that's what makes us normal people actually more like week living creatures.

    and think about it!! If the world's beginning is something about science that means there must have been something that caused to something that caused the big explosion BUT THERE WERE NOTHING!!! And out of nothing comes nothing!!!!!
    This theory is about very small elements that caused an explosion but where did they come from??
    No answer but god i guess right??

    If time is relative think about this:

    What if the Big Bounce Theory is correct stating their were universes before our on.

    What if the technology we perceive to be advanced really isn’t.

    What if a universe before our own had the very tools we do now such as internet, smart phones, cars.. and so on.

    This could’ve happened trillions of years ago but because once again time is relative it doesn’t matter. What if we aren’t as smart as we think we are.

    What if the universe is an endless loop and we are just one of many to experience a moment in time such as this.

    [Quran 21.104] "On the day when We will fold the heaven, like the folder compacts the books, and as We originated the first creation We shall return it; a promise ; surely We will deliver."(4:48)

    [Quran 41.11] "Then He directed himself to the Heaven when it was SMOKE, and then said to it and to Earth: "Come willingly or by force" they said "We do come willingly"
    "

    This video explained nothing and brought things into the equation that don’t exist in the universe? Ok I’ll believe this to be factual when clearly it’s faith based but I’ll tell everyone it’s factual and in no way it’s a religion 🙃
