What's the difference between vacuum energy and dark energy?
Is it that vacuum energy is equivalent to zero point energy as measured by the Casimir effect, Lamb shift and spontaneous decay?
And that dark energy is a hypothesised form of energy made up of zero point energy and scalar fields, such as the Higgs field, that permeates all of space and which would therefore explain the accelerating expansion of the universe?
So one is an experimentally verified phenomenon, while the other is an unverified hypothesis that intends to explain an observed phenomenon?

The difference is that dark energy is 10^115 times as powerful as the expected effect of vacuum energy.

one is real, the other is not

Right ok, so the accelerating expansion of the universe would require that much energy.
So we're left with a massive amount of mystical invisible energy?

That sounds a lot like:
>So one is an experimentally verified phenomenon, while the other is an unverified hypothesis that intends to explain an observed phenomenon
So, ok cool.

Just to clarify...
So the universe is expanding at an accelerating rate and this acceleration has to be due to some form of energy.
However, the energy required to provide for the observed acceleration is 10^115 larger than what can be accounted for by vacuum energy?

I take it back
I looked up what they mean with vacuum energy and that sounds like fiction too
>>8205605
what about quarks
how are they related to vacuum energy
>>8205605
>Yes, and we call that mystical invisible energy "dark energy" regardless of what is responsible for it.
Ok, brilliant.

I think he might be referring to the observation that quarks only make up 5% the mass of a proton; this wouldn’t make much sense without vacuum energy.
Is that correct?
I’m unsure of my knowledge about all this.

>The rest masses of quarks contribute only about 1% of a proton's mass, however.[2] The remainder of a proton's mass is due to quantum chromodynamics binding energy, which includes the kinetic energy of the quarks and the energy of the gluon fields that bind the quarks together

That doesn't even make any sense, anon.
