No physics, no laws of physics, no restrictions, only permissions, including FTL.
Even in the inflationary epoch, nothing went FTL as far as I understand it. Space merely expanded. Quite quickly, admittedly. But things didn't travel FTL. And still don't. Space simply expands such that more distant objects appear to move away from us FTL, but they are not travelling.
And there were laws during the inflationary epoch. Unsurprisingly, they are the same laws as govern the universe at the moment. The laws didn't suddenly change. The conditions were different, allowing the inflation, but the laws themselves still hold.
IMO, the BB was a "singular" event. I would hazard a guess that the BB was a single mega-quantum event where everything happened all at once and all at the same time. Chronology (time) and physical laws emerged after the event along with the emergence of matter and physical interactions.
Not "after the event" but "with the event". It makes no sense for time to start "after" an event, as "after" implies a passage of time.
Well, I am simply going by the evidence. After the BB, as spacetime inflated and cooled, laws of physics emerged along with matter from potential state to being expressed as physical permissions and restrictions. The Laws of Chaos! Emergent physical phenomena.
You may think you're going by the evidence but I think you have misinterpreted it. The laws of physics of this universe began, as far as we know, with this universe. They didn't "emerge". They were there from the start and continue. It is that very invariance of the physical laws that has allowed scientists to be able to model the universe back to pretty much the first moment, and why we believe those laws break down at t=0. It is the invariance of those laws that has given rise to the current models, and all the variations thereof. The only things that have changed have been the conditions that the laws apply to. We may only have discovered some pertinent to current conditions, but they were still all part of the universe from t=0.
Yes, IMO, what happened before the BB has no bearing on our reality at all. It would be interesting to form a model, but it would be useless as those conditions no longer exist or will ever exist again..
We can't form a model other than out of pure speculation. There is no predictive value in any model. We have zero knowledge of it, other than one example of what it gave rise to. You say that the conditions "no longer exist or will ever exist again" but those conditions
never existed within our universe. From after t=0 the universe was, at least as far as science understands it, a closed beast. This is precisely why we are able to theorise about, and model, the early universe.
Our world did not start until spacetime became geometrically measurable and particles acquired mass, as soon as temperature "allowed" (a physical law invoked by cooling plasma).
Our universe began at t=0. While the inflationary epoch lasted until c.10E-32 seconds or so, the universe did exist before then, although there are no theories with predictive value before 10E-43 seconds (Planck epoch). It is thought, however, that particles acquired mass around 10E-12 seconds. That is quite a long time (in universe-formation terms) after the inflationary epoch. But even before then... the universe did exist.
Well yes, but only those laws which were directly invoked by the inflationary epoch.
For instance, the law of exponential function was probably non-existent before the BB. There was only a singularity and the law of gravity, nothing was expanding , yet.
With the event of the BB the universe started inflating (expanding) in accordance with the law of "exponential function".
The laws of physics did not emerge until matter started appearing.
That is a rather curious way to look at things. The laws of physics still apply to electromagnetism, to gravity, to Higgs Bosons, to electronuclear forces etc. Matter is just a more recent form of what was already there. Physics applies to them all, from t=0. Only the conditions changed.
P.S. Sarkus, thank you for your patience and allowing me to explain further when my posts lack clarity.
