    Summary:
    Where did the first atom come from? The short answer is the big bang. In the early universe there was an immense amount of energy, The energy condensed, atoms formed. But there's a lot more that happened, which will be explained here.
    The big bang is often thought of as the theory explaining the beginning. but it’s not. We don’t know when the universe actually started, or whether it did. Our best theory of the early universe is the standard model of cosmology, We can only go back to one Planck time, about 10^-43 seconds. This is the smallest unit of time that can theoretically exist according to quantum mechanics. We don't know what came before this.
    The earliest time we can theorize what happened is around the time of inflation. This is when the universe expanded exponentially from about 10^-36 to 10^-33 seconds after the big bang. The universe expanded faster than the speed of light. This is permissible because there is no theoretical restriction on how fast space can expand. I
    The proper way to understand the term “big bang”, is not as some point or object from which the universe started, but as a period in the early universe, when the universe was very hot, very dense, and expanding rapidly.
    The theory of the standard model of cosmology is well understood starting at about 10-12 seconds, because the universe at this point had energies that can be replicated in our particle accelerators.
    In terms of the forces, gravity separated from the unified force shortly after the Planck Epoch at 10^-43 seconds. The strong force separated at around the time of inflation 10^-32 seconds. But from 10^-32 seconds to 10^-12 seconds, the electromagnetic and weak forces were still united as the electroweak force. The universe probably consisted of quarks and gluons in a quark-gluon plasma. All these fundamental particles were massless, because the Higgs field was massless at this point.
    At 10^-11 seconds, the temperature fell to one quadrillion Kelvin. This leads to electroweak symmetry breaking and the beginning of the quark epoch. The electromagnetic and weak forces become separate forces, and the Higgs field gained a non-zero potential, the particles of the Standard Model obtain their rest mass.
    The universe is however still too hot for the quarks to combine together to form hadrons like protons and neutrons.
    As temperatures cool to1 trillion Kelvin at 10-5 seconds, the quark plasma turns into a hadron gas made of protons, neutrons, and some mesons.
    As the universe keeps cooling down, matter antimatter begin annihilating with particles creating lighter particle and antiparticle pairs, eventually ending up as the lightest particles - neutrinos and photons. For some reason more particles were created than antiparticles. If this annihilation were symmetric, then we would have had a universe consisting of nothing except photons and neutrinos.
    A few protons, neutrons, and electrons were left over, the building blocks needed for atoms. After the universe was a few minutes old, the temperature dropped below 1 billion Kelvin, big bang nucleosynthesis or BBN happened.
    BBN lasts up to the universe at 20 minutes old. The universe had 75% Hydrogen and 25% Helium-4, & trace amount of deuterium, Helium-3 and Lithium-9 nuclei. The universe consisted of 87% protons and 13% neutrons.
    Note that at this point in time it’s all ionized nuclei, only the core of the atoms exists - no electrons bound to them. The universe so hot that the electrons could not attach to the nucleons.
    #firstatoms
    #bigbangnucleosynthesis
    The universe was still opaque because the photons that carry light as they interacted with the nucleons and electrons flying around. They were not free to propagate through space. This photon epoch lasts for 380,000 years until the universe cools down to 3000 Kelvin. Electrons can now bind to the nucleons to make neutral and stable atoms. This is called recombination.
    Photons were now free to propagate through the universe. This first light of the universe is what we see today as the cosmic microwave background or CMB. This light was released as the first stable neutral atoms were formed.

      What is outside of your consciousness?
      The question of outside generates a perception that there is a division between the inside and the outside.
      To simplify our body is a moebus strip. The inside of our intestin is still outside.
      The concept "outside" is a concept ti cut the univers in manageable chunks. It is useful when we find it useful.
      There it is revealed that concepts are action. And disappear when not used.
      Like denial is an action.
      Its effect ceases as soon as it's purpose is done.
      The univers was different to the one doing the denial, and thus the univers was diferent.
      I am pointing out our responsibility in asking a question.
      How ir shapes carves an answer out of the univers.

      I'm not sure but I don't think so.
      I find it really annoying if people talk about energy as if it's an entity with intrinsic properties.
      Well it's supposed to be model and concept that represent what actually is as closely as possible. I agree that many of them today have nothing to do with the actual but that's not because language is a thing.
      If we are not playing semantic games we should be able to handle the distortion layer that comes with language without bigger issues.

    I have three questions
    1. When matter and antimatter annihilate each other and they turns into energy, what happens afterwards? What happens to that energy?
    2. If that energy remains in our universe, can they be transformed in matter or antimatter?
    3. Like matter or heat, can energy create blackholes as well?

    • @kenlogsdon7095
      @kenlogsdon7095 2 роки тому +25

      I'll offer my answers if you like.
      1. The products of matter-antimatter annihilation are typically bosons such as photons and gluons. Depending on the amount of energy involved in the annihilation including particle masses and kinetic energy, other particles may be created as well. This undoubtedly was the case until the annihilation process resulted in mostly photons being created that were subsequently scattered and absorbed by the sea of hyperplasmic fermions that remained.
      2. Energy can in principle be converted between one form and any other. That includes mass-energy, kinetic energy, EM radiation, etc. For example, a gamma ray photon of sufficiently high frequency, and therefore energy, can transform into an electron-positron pair.
      3. Black holes are typically the result of a sufficiently dense concentration of mass-energy of matter in a relatively small volume of space, due to gravitational effects. Gravitation, as you probably know, is the reflection of the presence of any form of energy, referred to as "spacetime curvature".

    I know I read about this before but my question is this: when we use theory to roll back the clock all the way to the Planck time at t=10^-43 seconds, there is obviously no standard of time to keep track of these events, so what part of general relativity do we use to tell how far apart in nanoseconds the earliest events were. The Higgs field didn’t exist yet so clocks wouldn’t have worked yet since everything was massless, right? Yet we have solid evidence and theoretical basis for marking these events with these very specific times. How are we able to do this?
    Thanks again Arvin, you rock dude.

    • @ArvinAsh
      @ArvinAsh  2 роки тому +54

      That's a very good question. Relativity also shows that there is no absolute time, so there is nothing like a standard with which to measure these time frames. 10^-43 just comes from quantum mechanics and is the smallest possible increment of time that can exist mathematically. However, this does not mean that there was nothing prior to this. There may have been, but we don't have a theory to explain it if there was.

    • @alphalunamare
      @alphalunamare 2 роки тому +7

      10^-43 is a timestamp consistent with our current theories there is nothing to suggest that it is absolute, it is merely an extrapolation back in time as we currently understand it. The same applies to all the time stamps shown,, but perhaps they get more accurate the nearer they are to today. I am not sure that no mass implies no time since energy existed by definition and clearly Physics assumes changes in the energy distribution hence 'local' states of energy which in turns predicates the 'possibility' of time as a sequential measure of 'state' evolution? As for what part of General Relativity we use then clearly it is the part yet to be unravelled :-)

What interaction between the atoms (of surface of reflecting material) and photon (or light wave ) happens that reflects back the light.

      Oversimplified: When photons contact the electrons of atoms on any particular surface, not all the energy of the photos is absorbed. The photons which are not absorbed are reflected off. These photons are what you see when they enter your eyes.

    Hey Arvin, can you talk about the density of photons in the Universe? The fact that a star, 100 lightyears away, has emitted so many photons that even 100 lightyears away, at the surface of a sphere 100 lightyears in radius, we are still fully saturated in those photons? The volume of that sphere is incomprehensible, and yet, it's *filled* with photons from that star, and virtually every other in that range, such that we can't move so much as a millimeter left or right without interruption?

      To answer "why is a creator necessary", well aside from the big bang and creation of the universe itself we can look at biology. Based on our current understanding and progress in abiogenesis and genetic research we can safely come to the conclusion that a creator is very necessary. The thing is when we look at operational, demonstrable science it leads us to the conclusion of design. Evolution only works with untested and convoluted theoretical models.
      For example we contain arbitrary genetic code, how did this come about? We know all arbitrary code comes from a mind, this is a fact. Evolutionist then go on to spew comical theoretical models of how an arbitrary code could naturally form with no evidence, such as the "frozen model". This is just one of the many fatal flaws in evolution and aspects of biology that demand a creator...we could get into the failure of abiogenesis research and the non existence of natural mechanisms capable of forming the first cell, or gaps within the archaeological record such as "the cambrian explosion" or even modern day genetic evidence that corroborates with the Bible such as humans descending from 3 mtDNA lineages/noahs 3 children, or mitochondrial Eve and y chromosonal Adam but ill stop there.

Inflation came from the inflation field, which quantum tunneled into a lower energy state and saturated our universe with particles.
      Of course you can then say where that energy came from and so on and on. But it's still incorrect to say energy was created I'm the big bang because it already had the energy. We don't really know where the "first energy" came from, or if that's even a thing. Remember, existence has absolutely no obligation to be completely understandable by squishy little human brains.

    So I recently heard that (and oi forget who) physicists have recreated a model of the cmb in a simulation with more accuracy than ever before, and this is due to a scalar theory of gravity that changes on different scales. Be that as it may, with this "scalar gravity" that acts differently at the quantum (and the inflation epoch) and what we experience as gravity today across the universe, in my unprofessional opinion leaves open the possibility of a 'big bounce', or maybe even cosmological natural selection, as legitimate possibilities. From what we know today about dark energy, and thats essentially nothing, we know its basically 'anti-gravity' - repulsive in nature. and if gravity is just distortions in the fabric of spacetime caused by mass, then maybe it is helpful to think of dark matter as a 'negative distortion to the 4d fabric of spacetime? idk im stoned and im just spittballing the inklings of ideas ive had in my head nd no one to talk shop with haha!

That would have been a massive star and it would have left a blackhole when it exploded. This is the only explanation for why we experience time dilation here on earth and why the core of our planet rotates faster than the outer layers. This also explains why small bodies don't have a magnetic field because there is not enough time dilation to allow the inner layers to orbit the singularity at a speed high enough to create the friction that drives the magnetic field of planets stars and moons. They probably have a very weak magnetic field that isn't powerful enough to radiate out because the body is to small for time dilation to speed up the inner core enough to generate a strong magnetic field. Smaller core moving closer to the speed of the outer layers because not a lot of dilation. Lets say the universe is in the shape of a syringe right now the needle tip would still be the center or that is my view anyways.
