Science, Religion, and the Big Bang


Physicists used to think that the universe
had existed forever, unchangingly, because that’s what their observations of the night
sky suggested. Needless to say, this view clashed with the “origin” or “creation” stories
of most major religions, which hold that the universe had a beginning. So it’s not surprising that it was a Catholic
priest, Georges Lemaître, who was one of the first major proponents of a new scientific
viewpoint – that the universe DID have a beginning. Lemaître, of course, was also an excellent
mathematician and scientist and based this conviction not (just) on his religious beliefs
but upon new experimental evidence from Edwin Hubble that showed the universe was expanding.
This evidence, combined with the mathematics of general relativity allowed Lemaître to
“rewind” cosmic history and calculate that the farther back in time you go, the smaller
the universe had to be. The natural conclusion is that everything we can currently see in
the universe was at one point in time more or less at one point in space. Lemaître called
this idea the “primeval atom”, but of course today we know it as “the big bang theory”. Except “big bang” is a horrible name – it
would be much more accurate to call it “the everywhere stretch”. Because one of the most
common misconceptions about the big bang is that it implies that the entire universe was
compressed into a single point from which it then somehow expanded into the surrounding…
nothingness? It is true that the observable universe, that is, the part of the whole universe
we can see from earth, WAS indeed shrunk down to a very very small bit of space, but that
bit of space was NOT a single point, nor was the rest of the Universe also in that same
bit of space. The explanation for this is the magical power
of infinity. The whole universe is really big – current data show it’s at least 20 times
bigger than the observable universe, but that’s just a lower bound – it might be infinite.
And if you have an infinite amount of space, you can scale space down, shrink everything
to minuscule proportions, and still have an infinite amount of space. Kind of like how
you can zoom out as much as you want from a number line, but it’ll still be an infinite
number line. Essentially, space doesn’t need anywhere to
expand “into” because it can expand into itself and still have plenty of room. In fact, this
is possible even if space turns out not to be infinite in size, though the reasons are
complicated and have to do with the infinite differentiability of the metric of spacetime… But anyway, the event unfortunately known
as the big bang was basically a time, long ago, when space was much more squeezed together,
and the observable universe, that is, everything that we see from earth, was crammed into a
very very small piece of space. Because the ENTIRE early universe was dense and hot everywhere,
spacetime was curved everywhere and this curvature manifested itself as a rapid expansion of
space throughout the universe. And although people call this “the big bang”, it wasn’t
just big, it was everywhere. And it wasn’t really an explosion – it was space stretching
out. It’s really quite unfortunate that “the Everywhere Stretch” isn’t nearly as catchy
as “the Big Bang”. Which brings us to the “big bang singularity”,
which is an even horribler name because every single word is misleading. I mean, “singularity”
seems to imply something that happened at a single point. Which isn’t at all what it’s
referring to – it SHOULD be called “the part of the Everywhere Stretch where we don’t know
what we’re talking about.” Basically, our current physical models for the universe are
unable to properly explain and predict what was happening at the very very beginning when
the universe was super SUPER scaled down. But rather than call it the “time when we
don’t have a clue what was happening, ANYWHERE”, for some reason we call it a “singularity”. This ignorance, however, does conveniently
answer the question What happened BEFORE the big bang? Because it tells us the question
isn’t well defined – back when space was so incredibly compressed and everything was ridiculously
hot and dense, our mathematical models of the universe break down SO MUCH that “time”
doesn’t even make sense. It’s kind of like how at the north pole, the concept of “north”
breaks down – I mean, what’s north of the north pole? The only thing you can say is
that everywhere on earth is south of the north pole, or similarly everywhen in the universe
is after… the beginning. But once time began, whenever that was, space
expanded incredibly quickly all throughout the universe – for a little while. Then expansion
slowed, the universe cooled, stuff happened, and after a few billion years, here we are. One thing we still DON’T know is why this
Everywhere Stretching happened – that is, why did the universe start off in such a funny,
compressed state, and why did it follow the seemingly arbitrary laws of physics that have
governed its expansion and development ever since? For Georges Lemaître, this might be where
God finally comes into the picture to explain the things science can’t. Except that experimental
evidence doesn’t actually rule out the possibility that there may indeed be a time “before” the
beginning, a previous age of the universe that ended when space collapsed in on itself,
getting quite compressed and dense and hot, but not enough to mangle up our ideas of what
time is. It would have then bounced back out, stretching in a fashion similar to what we
call the big bang, but without the “we don’t know what we’re talking about” singularity
part. So, physics may actually be nudging us back to the view that the Universe is eternal
and didn’t begin after all. In which case Professor Lemaître might have to rethink
his interpretation of the words “in the beginning.”

  1. All well and fine, but when you consider that space cannot be infinite or it would still be infinite no mater how much you divided it up. The big bounce paradigm is, however, consistent with the Brahmin cosmogony. It could also be construed to be consistent with the Christ myth. After all, if the universe eternally buries and resurrects itself, would that not be consistent with the narrative of the New Testament?

  2. alquran about bigbang .(21:30) Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?

  3. alquran about bigbang, fushilat 11: Then He directed Himself to the heaven while it was smoke and said to it and to the earth, "Come [into being], willingly or by compulsion." They said, "We have come willingly."

  4. quran about the universe continues grow ,azzariat (51:47) And the heaven We constructed with strength, and indeed, We are [its] expander.

  5. quran about blackhole , Al-maarij (1-2): [It is] from Allah, owner of the ways of ascent.
    The angels and the Spirit will ascend to Him during a Day the extent of which is fifty thousand years.

  6. quran about bigbang ,Alanbiya (30):
    Have those who disbelieved not considered that the heavens and the earth
    were a joined entity, and We separated them and made from water every
    living thing? Then will they not believe?

  7. Pretty good, loved the analogy. Especially the one concerning the North Pole and how asking "what happened before the Big Bang" is nonsensical, supposing that the Big Bang was really the beginning of the universe. The thing is, people conflate the Big Bang Model with the actual event itself; the moment in time. The Big Bang event is necessitated under a classical understanding of of relativity, which we know isn't the answer. We know that the real universe is quantum and we have 0 evidence to believe that this is false, physicists just need to start understanding it (That's why you should all buy Sean Carroll's "Something Deeply Hidden," it comes out in September).

    Also, the concept of "God" doesn't fit at all into contemporary cosmology and physics. Cosmology builds self contained, formal mathematical models that explain the entire history of the universe and reflect known data, and there is no room for God to have brought the universe into existence in these models. Cosmology also doesn't answer the purpose and meaning questions, the "why did the Big Bang happen" or "why are the laws of physics the way they are" are not really questions with answers. These are questions that our merely human rationality devise based on our everyday experience of life on Earth which in no way is representative of the fundamental nature of the universe. That comes through differential equations and building models, not philosophical principles of a "first cause" or "prime mover."

  8. He was doing really good for a second near the end. “Well maybe there is a God” to “well maybe the universe is actually eternal.”

    Smh almost had ‘em.

  9. After each cycle of expanding and contracting, the universe would accuire more entropy and thus expand more and be longer before the next cycle. Thus if we go back in time, the cycles get smaller and smaller to a point where their is a beginning to these cycles. Scientists conclude, based on the amount of radiation in our universe, that the universe couldn't have gone through more that a hundred or so of these cycles before needing a beginning. This is an old and disproved theory. A good explanation of it though.

  10. I I need stronger comments and strong stronger videos because I am trying to do a report also a video I mean not video well a a Dot-dot-dot a a passage about and science about what is my religion and what's the difference between the big bang and what's my argument and I can't do nothing about it so you have information which one as well please call me thank you

  11. Anything to say God doesn’t exist, they’ll do 😂 Genesis 1:1 “In the beginning God created the heaven and the earth.” <— BAM ! Walk outside, look up …there’s Heaven and the ground you’re standing on is Earth. Science is stupid. The Bible is real. Don’t be fooled

  12. Right, so magic. 2nd law of thermodynamics refutes the idea that it compressed back into a ball and then exploded again.

    Where did the matter come from? If space itself were to expand, how could we possibly tell, given that we are in space? Wouldn't the molecules in our eyes expand at the same rate?

  13. I have one question…if everything was so tiny before…and it started to expand, wouldn't it still be expanding and wouldn't humans, sun, animals, plants, stars, and the moon continue to get bigger?

  14. the three religions were right about the beginning of this universe and life, Judaism Christianity and Islam, the books explaied briefly the things that scientists take ages to figure out, no one can understand or tell the truth about life and universe more than the creature himself…cool video tho

  15. My only problem with this is that the universe could not have been here for ever proven by the second law of thermodynamics

  16. Laws of nature were made, Sacred Geometry is a thing, Nature patterns is a thing.
    Space, Gravity and Evolution are all Swiss Octogone Templar ilusions/lies, we live in a pharaoh pagan babylonian system of sins and "freedom of choice", we are stuck in it, satan rules the Earth, earth is no more then 6000 years old
    Wake up.
    "Truth is hidden in plain sight"
    "Reality is stranger then reality"

  20. As a moslem, I'm personally not surprised by this. God has talked about this in the Quran 21:30 and 51:47. No one knows a thing better than its creator.

  21. Yes! The universe is DEFINITLY eternal. Because something never came from nothing. Something always existed. The whole of what existed at any time WAS the universe at that time–So the universe IS eternal.

  22. Can't people see the word "set" in Genesis one KJV? God set the stars in the universes. They were eternal. God's enemy made them to look, like rosy paint. Muslims Allah did that, being Lucifer, who is Satan. The physics that we see now, are not the physics that were, before death.

  23. "Because the early universe was dense and hot everywhere space-time was also curved everywhere. This manifests itself as a rapid expansion everywhere". How does hot/dense mean space-time was curved? Its it because hot/dense means matter/energy and we know that matter bends space-time from general relativity? But at this "singularity", doesn't all the understanding of physics breakdown? Or is this a question of extrapolating and assuming physics is still as we know it?

    I do have a problem wrapping my head around all of this, so maybe I'm just going crazy and this is super logical.

  24. Eternal universe seems precluded because of entropy. We would have run out of useful energy already. Entropy even causes black holes to shrivel up and die.

  25. Its a nice explanation but lets be honest no one knows what the fuck the origins were and it so annoying coz damn I really want to know

  26. The model of an expanding and collapsing universe is most likely not true. The well-respected physicist Alexander Vilenkin (might have butchered that) proves this. He is an agnostic, by the way.

  27. Why am I watching this mambling about something about which I'll never find out in my life when I have so much important work to do?

  28. Have those who disbelieved not considered that the heavens and the earth were a joined entity, then We separated them, and made from water every living thing?  Then will they not believe?” (Quran 21:30)

  29. It's common to be triggered for both when a non secular utube channel speaks on religion,and when John Lennox speaks on athiesm😂😂🤣

  30. Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? (Quran 21:30)

    And the heaven We created with might, and indeed We are (its) expander.” (Quran 51:47)

  31. This YouTuber needs a minute philosophy class. Or decade, given his stupidity.

    The fundamental question is: why is there something rather than nothing?

    The mechanism of the universal beginning is irrelevant. The relevant issue is the stuff we see. Matter. How and why is there stuff? Who put stuff into nothingness? Who created stuff ?

    It must be a non-matter entity. Non spatiotemporal, in fact. That's God.

  32. Pseudo-Scientists created "Hubble" which does not exist, the "universe", and "space".

  33. An endless universe in its own way has issues. Because it's just… Well, how does… But when did it… Except it's eternal… Huh?

    Mind, EVERY system breaks down eventually, even the idea of a God or Gods – What made them? Etc.

  34. 1 In the beginning was the Word, and the Word was with God, and the Word was God.

    2 The same was in the beginning with God.

    3 All things were made by him; and without him was not any thing made that was made.

    4 In him was life; and the life was the light of men.

    5 And the light shineth in darkness; and the darkness comprehended it not.

  35. That priest is looking at what satan did bring death. Catholic leaders, are in love with death. They have sacrificed children, in the Vatican, in rituals. I am not lying.

  36. Child: "So when did everything begin?"
    Scientist: "The big bang"
    Child: "What happened before that?"
    Scientist: "We don't know"
    Child: "Why didn't you just say that then?"
    Scientist: "I don't know"

  37. Does that mean that the universe is a three dimensional surface of a 4 dimensional sphere that is expanding into the fourth dimension (aka time)?

  38. Before the Big Bang became an established working theory, religious people said "God did it." After it became common knowledge, the religious said "God made it happen." The wonderful thing about being religious is that you can always argue with conjecture and speculation, rather than evidence and facts.

  39. why you only talk about christianity xD you said religions
    and you didn't send this

    [Quran 21.30] Do not those who disbelieve see that the heavens and the Earth were meshed together then We ripped them apart? And then We made of water everything living? Would they still not believe?

  40. How will big bang be infinite if the universe is expanding? If universe has an end, how is it gonna bounce back? It says that the universe is expanding slowly.

  41. Clearly scientists are looking for the creator often referred to as god. Judging by the gaps and speculation in big bang theory, they will be looking for a while yet.

  42. Science teaches us that the universe started from a extremely small point, much smaller than a atom. Based on this fact, logic then tells me that it has to be caused by a singular conscience. Which means only one thing. That there is only one God. And this God by logic would have to exist outside of the created physical universe. Which means that He then must be independent of the laws of physics. Which then means that time does not apply to him. Which then tells me the created universes has a beginning and will end. Which then tells me by logic it can’t be infinite. Only the creators attributes are infinite. Atheists keep asking the question who is this God and where is this God. Gods answer is this – “ I am The Existence which is beyond all your intellects, intelligence, thoughts, imaginations, logic, reasoning, emotions. I am ungraspable from all visions, hearing, sound , touch, smell, taste. I am not a animal, or super human. I am not a color. I am not the sun, or moon. I am not a star or planet. I am not a galaxy, I am not a black hole. I am not water, I am not light or darkness, I am not electricity or fire. I am not a energy. I am not a mass, depth, width, length. I am not Jesus, or Muhammad, or Moses, I am not, Shiva, I am not Kali Maa or Brahmin. I am not the universe. I am The Greatest Conceivable Existence. I have no family, no father, no mother, no children. I am the Lord of The Heavens and The Earth. And I feel no fatigue or slumber in guarding and preserving them. I am Thee God. Allah.
