Physics is always trying to unify the forces and combine theories into one super theory. Why is this assumption always made and never questioned ? Why couldn't we indeed be in a world with 4 forces or maybe even 50 different forces governed by 50 different perfect theories that don't unite and are not one "unified theory" ? Why can't we just let go of this GROSSLY OVERESTIMATED ASSUMPTION every now and then ? What is wrong if the universe is made up of 50 distinct perfectly working theories and forces? Why must they absolutely unite ? Maybe we should seriously try to make a grand explosion of theories, and maybe we could reach something new. Granted 3 forces have been united successfully but are we really sure this is the right direction to proceed ?
