How did universal mathematical laws evolve from or with the big bang? Can grasp how we are made from star dust but where were mathematics lurking/evolving, all that time?

In helicopters, torque balancing is done by the extra rear propeller. But in airplanes, no such balancing is evident. Even the engines of jumbo jets turn all in the same sense. For stability, the Sum of all torques MUST be 0. Is the sum of the propellers or jets torques so small as not to influence equilibrium? If not, what is the mechanism used to stabilize the plane? It seems to me that, except for helicopters, all propellers are small BUT they turn very fast. So, the momentum generated must be quite large. Please feel free to use engineering notation in your answer. Thanx!

piece of evidence is the background radiation of heat left over from the Big Bang. This was predicted to exist by proponents of the Big Bang, and was discovered accidentally in 1963. It's the leftovers of the tremendous heat generated by the explosion, and is 2.93 degrees above absolute zero.
Where could i find this proof or theroy on the web^^^?
They say "Galaxy are expanding" when the fact is some have blue light and some have red, we dont no whether we are expaning or contracting????
Whats with that?

Is it true that due to an anomaly with either the gravitational or magnetic force, that there are some places on earth where an object can roll up hill without any additional force, or is it just a myth?

Dinosaurs were around for tens of millions of years but don't appear to have eveolved into a language speaking, culture creating species. It took an ape descendent about 200,000 years to evolve into something like us. Was the dinosaur genotype incapable of giving rise to a human-like intelligent species? Also we seem to have come far very quickly. Is there any limit to what our genotype can give rise to, assuming of course that we don't self destruct.
