Well, I suppose if we're going back to a time when the universe was nothing but an empty void - no motion, no gravity, no planets or stars, there doesn't appear there would be any occasion for such laws to apply.
What make you think there was “nothing”?
What make you think there was “empty void”?
And please define “nothing” and define “empty void”?
The Big Bang theory proposed neither.
The problems with science illiterate is that they don’t bother to read, to understand or to ask questions, so they often misunderstand the Big Bang model, and then make assumptions and claims that have nothing to do with the current model.
They also misunderstand what “singularity” means (in the context of the Big Bang model), and again wrongly assume it is “nothingness”.
So please define these claims you have made, as they don’t not related to the Big Bang theory.
Also. When I hear or read the word “void” being used, often I think of “space” - the intergalactic space (the “space” between galaxies) that astronomers often observed.
I don’t think of void being the singularity.
Like I have been asking you, how do you define “void”, “nothing”.
Oh, btw.
You’ve claimed there were “no gravity”. I am thinking of one of the fundamental forces or fundamental interactions in science - GRAVITATION.
The other 3 forces being -
- Strong nuclear force (or Strong Interaction)
- Weak nuclear force (or Weak Interaction)
- Electromagnetic force (EM Interaction)
In the current model of Big Bang theory - the ΛCDM (late 1990s) - as well as our understanding of particle physics (eg Standard Model) and the Grand Unified Theory (GUT), and of the Quantum Field Theory (QFT) - the Big Bang theory started with the Planck Epoch (from 0 to “about” 10^-43 seconds).
In this Planck Epoch, the universe was in infinitely hot & dense state, where it is not possible distinguish any of particles (eg bosons, quarks, leptons, etc), because the universe was nothing but plasma, which some physicists would describe as primordial soup.
Also the four forces (gravitation, strong, weak and EM) were unified as single force.
The four fundamental forces are indistinguishable as single unified force.
When the universe began expanding, the universe would be less hot and dense than the period of the Planck Epoch. The next period is called the Grand Unification Epoch (GUE), from 10^-43 to about 10^-36 seconds after the Big Bang.
The expansion in the GUE, the universe dropped to temperature of 10^27 K and energy of 10^15 GeV (or 10^24 eV), cool enough for gravitational force to separate from the unified force, the electronuclear force (EM, weak & strong).
The separation of force from unified force is called “Symmetry Breaking”. Two more Symmetry Breaking would occur in the following epochs:
- Strong interaction is the next Symmetry Breaking from the electroweak force, occurring during the Electroweak Epoch (10^-36 to 10^-12 seconds after BB); EM & weak nuclear are still unified as electroweak force. The temperature would have to drop to 159 GeV for strong force to separate from unified force.
- Symmetry Breaking of electroweak force into weak nuclear force and EM force, during the Quark Epoch (10^-12 to 10^-6 seconds after BB). For the last breaking to occur, temperature would have been 1 TeV (or 10^12 eV).
Each successive Symmetry Breakings occurred was the result of the energy drops and temperature drops during these 3 epochs.
To give you some perspective as to the energy for strong force to separate from unified "electronuclear" force of 10^24 eV or 10^15 GeV:
- Nuclear fission would release energy of about 2 MeV (eg the atomic bomb explosion).
- Nuclear fusion would release energy of about 17 MeV (eg the first thermonuclear explosion from the H-bomb (hydrogen bomb).
- Stellar Nucleosynthesis (nuclear fusion at the Sun's core) release about 26.2 MeV.
- The Sun's surface or Photosphere, has max temperature of 6000 K or 0.517 eV.
To unify EM force and weak nuclear force as a single electroweak force, today, would require energy level of 246 MeV. Even the Sun cannot produce such temperature.
My point is that gravitational force was unified with strong, weak & EM force during the Planck Epoch, so I wouldn't say gravity didn't exist.
