How the Quantum Vacuum Gave Rise to Galaxies



All the large-scale structure in the universe may owe its existence to nothing.

Let’s see how clearly I can explain this. We think of empty space as, well… empty, the epitome of nothingness. But as our understanding of physics has evolved we have realized that it’s not truly empty. Space is filled with fields. There is a field for every subatomic particle. One for electrons, up quarks, down quarks, neutrinos and so on. In empty space these fields are basically zero, flat, nil. But it’s impossible to make them perfectly zero so there are always some quantum fluctuations in the fields, even in a perfect vacuum. These are sometimes called virtual particles but they should really just be thought of as little disturbances in the field. Vacuum fluctuation play a role mediating the interactions of subatomic particles but they don’t really have an impact on the large-scale structure of the universe, EXCEPT during inflation, right after the big bang when the universe increased in size 10^26 times. Due to this rapid expansion, those tiny fluctuations were blown up to the scale of the observable universe. And we know this by looking at the cosmic microwave background radiation where we can see slightly hotter and cooler parts of the early universe that correspond to density fluctuations. And it is these density fluctuations that allowed matter to clump together into large structures like the gigantic gas clouds that would go on to contain stars and planets. In case the video isn’t clear, this is what I’ve been trying to say.

  1. He so elegantly said absolutely nothing at all. Nothing cannot make something out of nothing. It is far more reasonable that SOMEONE made something out of nothing. Enter God. Who, or what, made the quantum vacuum? A beginning requires a beginner…

  2. I've always wondered how they read the background radiation. In my mind, if radiation was emitted, it should travel onward through the universe. For instance, if you shine a torch, the light beams leave the torch and don't return (barring reflection.) You cannot look at the torch an hour later and still see the light it emitted. So how does one read the radiation from the start of the universe when it should have long passed us and on into the ether? I should probably look that up.

  3. Chaos never makes order. Simple.
    The Creator God of the heavens and earth created everything we see. This beautiful place just doesn't appear through a big bang but by the Words of God. He said let their be light and it all began. That's the beginning. The Bible KJV explains everything perfectly.

  4. Wait….. if gravitational time dilation is true, the so called 'big bang' explosion, from that relative perspective, could (I say 'would', and I would think so would Einstein too) have taken eons.
    What am I missing?
    This 'rapid' expansion, is still relativistic, right?
    So why so much focus on how quickly things happened at those moments just after the big bang? If time is relative, in the theorized compacted mass that became all that is.

  5. very short period : Quran "And to Allah belongs the unseen [aspects] of the heavens and the earth. And the command for the Hour is not but as a glance of the eye or even nearer. Indeed, Allah is over all things competent."

  6. Does it blow anyone elses mind, that scientists can say with confidence:

    "The universe was expanding steadily for the 1st nonillionth of a second, then it started expanding more rapidly"

    Like how can they know the timing of it to that level of detail. Something that happened billions of years ago.

  7. Could gravity have acted as a binding force to start and after a certain size was achieved then it acted as a binding force for the most distant objected more than the once kinda close objects to stuff is being pulled to the things that are furthest away which appears to make everything move away from each other?

  8. Combine:
    1. cosmological constant in Dxy [m^-2] = lp^2/λ^4= lp^2 Nxy ^2 [m^2] [m^-4]
    2. schrodinger solution
    3. Planck E= h f= h Nxy
    4. Nxy = number of superpositions per m^2= wave function frequency

    Result: dark matter = superpositions of the electron wich gives the electron extra weight

    Dxy [m^-2] = lp^2/λ^4= lp^2 Nxy^2 [m^2] [m^-4]

    Nxy = sqrt(Dxy / lp^2)= (Dxy / lp^2) ^0.5= [m^-1] [m^-1] = m^-2

    Nxy = sqrt ( 10^-52 / 10^ -70) = 10^18 ^0.5 = 10^9

    Schrodinger solution:

    Nxy^2 h^2 / ( 8 m L^2) = h Nxy

    8 m L^2 h Nxy = Nxy^2 h^2

    m = Nxy^2 h^2 /( 8 L^2 h Nxy)

    m = Nxy h 0.125 L^-2

    m= 10^9 10-34
    = 10^-25 ( all superpositions).

    1 particle = 0.331 10^-25 / ( 0.4 10^9) = 0.828 10^-34 kg = 46 eV

    If you count only the positive wave function amplitudes: n = 10^4.5
    then 1 particle = 0.331 10^-25 / ( 0.4 10^4.5) = 0.828 10^-30kg 5.6 10^35= 10^5 ev = 0.5 Mev

    Superposition (recoherence) of electron causes dark matter and expansion of the universe?

    And vacuum catastrophe solved:

    m= 10^9 10-34
    = 10^-25 ( all superpositions).

    E= m c^2= 10^-25 10^16= 10^-9 J m^-3

    Im curious for youre reaction
