Physics applied, sure, but not the physics we are acquainted with. There would be a wholly different set of rules that applied when everything existed in a single point - physicists are still honing in on what exactly these rules were. Note, however, that the idea of something happening "before" the Big Bang would be a bit of a misnomer: the Big Bang was when time itself started as well. The newly emerging Membrane Theory is offering some interesting possibilities regarding what was going on before the "Big Bang". If there is any truth to Membrane Theory (and there may be elements of it that help explain some weird things about gravity) then the big bang was the result of the collision of two previously existing universes. The collision doesn't happen as you might imagine. Universes are "membranes" at the quantum level, and alternate universes are all around us all the time.
The laws of physics, as we understand them, emerged shortly after the Big Bang once the universe had cooled down enough for particles to form and interact. Prior to this point, during the extreme heat and energy of the Big Bang itself, the laws of physics as we know them may not have been applicable.
The big bang hypothesis is just that, a hypothesis, and a hypothesis based on an extrapolation of an explanation of a Doppler frequency shift that is itself an unable to be proved hypothesis. So asking what went on before the big bang is meaningless and of course unanswerable. Consider this: The expressions, before and after imply the measure of time. Time did not exist before the BB, therefore the question is nonsensical. We can only spreak of 'after' the BB. Not before! Setting aside the issue of evolution and looking just at the Big Bang, the Big Bang created both space and time. It created the fabric we call spacetime in modern physics. It's not like the Big Bang happened in an "empty universe" that was here already with time passing in the void. No, the Big Bang actually "created the space" in which it now expands. And it created the time, too. These ideas are consequences of the Big Bang theory, and it is currently the best scientific way we have to explain the universe, explain how it formed and became what we can see all around us.
Science relies on the laws of physics. Faith and religion have no bearing on the laws of physics, unless you believe God created the laws of physics. While you can believe in God and be a scientist, it's hard to believe in the Big Bang theory and Creationism, too. And, modern physics now believes that God had no part in the Big Bang. That said, God and faith can still play a large part in our lives, just not when it comes to science.
Good question. If you get the answer, notify those folk in Stockholm. The states of matter and energy in the Big bang are so far away from our knowledge that the physics and math are beyond our ken. [It has been said that just before the big Bang there was a sense of something about to happen.] Some cosmologies suggest a Big Inflation, followed by a Big Collapse in a cyclic fashion. Fertile fields for the sci-fi writers, along with monopoles and FTL speeds.
That would be just before the Big Bang, for soon after some of the energy is converted to mass.

Theoretically, the forces were united in the conditions existing just before the Big Bang.
Nothing just put the bandage on
Before the Big Bang, the universe was incredibly small, dense, and hot. This tiny size suggests that all matter and energy were concentrated in a single point. The implications of this size are significant as it challenges our understanding of the origins of the cosmos, leading to questions about what existed before the Big Bang and how the universe began.
Just put some baby poweder before and after threading just apply rose water thats it!
We can never observe anything that occurred at the Big Bang or any time around then, because photons were not free to travel through the universe yet. If we accept that quantum mechanics was applicable to the creation of the universe, then the Heisenberg uncertainty principle dictates that all of the matter in the universe may have come from nothing.
The Big Bang is just another theory.
