Re: SWaB: Dark energy might be neither particle nor field
If its essence is ever revealed, then it will have to be renamed! After all, calling it "dark energy" is essentially making a statement confessing to not knowing what it is. Therefore, I humbly submit, that when the right time comes, it be renamed as... the aether.
"...while everything else clumps or clusters together, dark energy remains uniform throughout space and time. Instead of being a particle or field, it could be a property inherent to space itself..." Yep. Basically (well ok, more or less... close enough, right?) the aether!

And... Darn. Looks like somebody else got to this well ahead of me:

Re: SWaB: Dark energy might be neither particle nor field
Sean Carroll does a nice job of arguing against dark energy being like an "aether". If the OP's link is right then it's more like the vacuum energy of space itself. But who knows?AntennaGuy wrote: ↑Fri Sep 24, 2021 2:44 am If its essence is ever revealed, then it will have to be renamed!

I (impishly) note that with dark energy being the energy of space itself, I note that Carroll's motto on his blog "in truth, only atoms and the void" runs into conceptual problems. It is a translated quote from Democritus for whom the void was truly empty, null and void.
