First of all the fundamental forces of the universe are human observations of the behavior of matter and energy/space/time put into words to describe it as laws. Yes there was a point where there was no potential difference existed between matter/energy/space/time.<quoted text>
Wow, and you observed all of that?
Where did law come from by the way?
Was there a point where "law" did not exist?
Since space/time did not exist the question doesn't make sense.
Absolute zero is the point before the universe and where the physical laws do not apply. Since time does not exist then, there is no time before then. Since there is no time before then, no law can exist before then.
So far since we cannot duplicate the conditions of all forces unified or GUT Grand Unification Theory, it remains a paradox. Though several theory's try such as super string and quantum loop gravity all being considered to be attempts at Theory Of Everything models or TOE . All are simply where the laws of physics break down and no longer exist.
