If the BB is correct, at the moment of the explosion, the laws of physics began their 'appointed/determined/by chance tasks.
In so far as I understand it then, the laws pf physics were present before time began, eh?

I understand what you mean but there can be no laws before time began. As there would be nothing to obey the laws.
Therefore the laws of science came into existance at the same moment as the universe.

No!
Few scientists believe that - as the universe expands it takes spacetime with it - in fact thats probably misleading - its the spacetime itself thats expanding - if something as fundamental as time is part of the fabric then we have no idea what could possibly be before the big bang but there's no reason to assume the physical laws were the same - and indeed current physical laws tend to break down near singularities (black holes or a big bang) though that probably says more about the theories than anything else. It is likely though that physical laws would be different, possibly with fundamental constants at different values. You should also keep in mind that the Big Bang isn't actually a description of the very beginning - it only describes the expansion - a few tiny fractions of a second after the universe began - not that scientists haven't explored the first moment - read up on the 'ekpyrotic scenario' for one possible explanation.

Hey All ! Physics laws try to explain the phenomenon of Time & Space. In the process they have theorised about the Big Bang.
So obviously Physics is a science that seeks to explain a phenomenon that occurred.
Guess this should answer your question.
In short the BB theory is just a theory "Physics" has come up with for an explanation of this Universe.

Interesting question.
I read a book some time ago covering the first three minutes of the big bang which elaborated in detail from microsecond to microsecond how the universe evolved into the universe we see today. It seems that the universe was condensed into a singular point and that when the big bang occurred there was a clumping of matter into what we see today - the early universe was a homogenous region of superdense , superhot soup of high energy particles. By rational deduction i would guess that the laws of physics evolved as the properties of matter began to interact at the physical level. But if the question is how did the laws of physics present themselves ?
Them my assumption is that time is equated with space and mass ; time was condensed too ?! and as the universe expanded it slowed down to light speed. I'm hesitant to think that the speed of light was the brake in the universes explosion as time had yet to quantify or manifest itself according to our present day laws. i'll keep coming back to this to see what ppl think!

Time and space came into being at the moment the big bang occured, so before there was nothing...not even time its self.
Therefore the laws of physics didn't exsist, nothing did.
Read the book "The Big Bang" by Simon Singh, its a general science book that explains everything in a way that doesn't make your head hurt!

The BB is believed to have begun from an infinitely dense point (perhaps smaller than an air rifle BB) called a singularity and it is commonly believed that the laws of physics (as we know them) likely did not exist at time zero.

perhaps, but what if the universe before the big bang was totally different with totally different laws controlling it?
Impossible to tell.
What if our universe expands, slowly slowing down, stops then accellerate backs with gravity drawing everything back into one big mass. Which then goes BANG again,,, continuing for ever and ever ???

After the second space -time pulse occurred,the minimum time and the minimum distance were established.
This established the speed of light and set the stage for the universe that we see to-day.

Of course, all the laws of science have been there since day dot.
They are not material!
Just add water!!!
