Not quite sure what you’re saying here. Energy doesn’t have ‘weight’ like the energy of a photon - nobody would say has weight as photons are massless.
Er… um… hmm? What do you mean here? The soul is like the matter that doesn’t interact via the electromagnetic force but it interacts via gravity? We can measure exact amounts of Dark Matter and make maps of it. This sounds like hobble gobble which makes me question the ‘science’ of the other work above but I will be sure to check it out when I have some more time.
