So quarks are quarks, photons are photons and they have never changed their properties since the time of the big bang?

To be more specific, can we observe and possibly calculate in any way how atoms behave in cell and make some predictions how they will change with an evolving organism? eg, The evolution of vision is the compound and compacting of light sensitive patch(opsin proteins). With this, Photons and the...

ok... I am thinking that there has to be a connection from quarks to molecules that forms biological life and from this initial step has to kick start the process of Darwinian selection.! Are you saying that since the big bang, that this was the process de novo?

Does anyone know where I can get information on how particles such and quarks/lepton that form atoms, atoms to molecules and molecules to cellular life.? What area of physics is based on the area of study and can evolution of biological organism be traced?

From integral( dR/(sqrt(lambda*R^2/3) - K) = ct derivation has the initial conditions; lambda<0 K=-1 Leading to the oscillating universe

Does anyone know how to derive the result for an oscillating universe? R(t)= sqrt(3/lambda)sin(sqrt((3/lambda)ct) I would appreciate the help on this one

rho=0, lambda>0 and k=1 with the initial condition R(0) = sqrt(3/lambda), the solution is R(t) = sqrt(3/lambda)cosh*(sqrt(lambda/3)*ct) This the the de sitter universe, however i am having problems finding a way around how to solve it from the Friedmann equation...

Just wondering if any1 would by any chance know how to calculate the commutation relations when L = R x P is the angular momentum operator of a system? [Li, P.R]=? P
