Thanks Jaime. What if the inflationary period took much, much longer than the explosive expansion theorized?

Hi. If the early universe did not undergo rapid expansion but rather a more controlled growth like the human body, how old would the universe be given its present size? thanks

So if a nearly massless neutrino with no charge can penetrate matter with little likelihood of a collision, why doesn't a photon do the same thing"

if a photon is massless like the neutrino and has not charge like the neutrino, why doesn't it penetrate matter like the neutrino?

If spacetime is not a substance, where do virtual particles come from?

doesn't the kinetic energy of a photon give it a "mass" if energy=mass and mass=energy?
