Hey, If we use the Friedman Equation form to find time(excpected) for a given particle's Rest Mass energy as our input value, does it mean that the most energetic particles were 'born' first and the lighter particles 'born' later on in time in a linear, sequential order? eg. T quark (174Gev)---->Z Boson(~90GeV)----->W Boson(~80GeV)---->B Quark(5GeV)------>Tau(~1777MeV)-----Proton(~938MeV)----->Electron(0.511MeV)------>etc... Does the order of their Rest Mass energies mean they were 'born' in that order too? Thanks, I'm very puzzled about this.
