I AM SO NOT qualified to speak on this subject I’m almost afraid to ask the question. But…
Scientists are struggling to locate sufficient mass to explain the rotational speed of stars within galaxies. The stars are moving too fast, which implies that there’s more mass than can be accounted for by visible matter.
And my feeble little brain makes this leap.
E=MC2 is an equation. Perhaps obvious, but… If mass can have energy, why can’t energy have mass?
In other words, are we thinking about the problem wrong? Are we thinking about mass and energy as being discrete the way we used to think of space and time? The latter has revealed itself as space-time — a unified continuum. Might not we be better served to think of mass-energy as another unified continuum?
Might not the “missing” mass be contributed by the energy in a galaxy?
