What's the difference between vacuum energy and dark energy?

>>8205578
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.

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

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

That's silly. I suppose you don't into quarks.

>>8205595
Yes, and we call that mystical invisible energy "dark energy" regardless of what is responsible for it.

>>8205605
what about quarks

how are they related to vacuum energy

>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.

>>8205611
>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.
