I agree, anon.

I've been dead far longer than I've been alive.

I'll just be returning to the state that I've existed in for the majority of time.

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?

A Brief Overview of Cosmology.

As requested, I have returned in order to dedicate a thread to this topic.

Now I'm assuming you know that the universe is expanding uniformly as informed by the Doppler effect, spectrometry allows us to discern the composition of massive bodies, both light and gravity dissipate at 1/R2, velocity is proportional to distance and the number of proportionality is H and the expansion rate is measured against standard candles, such as supernovae.

v = Hd

H = 100h km/sec/Mpc

If not, then now you do.

Ok, on with the thread!
