Can anyone keep up with the dark debate?

[Guy]

First there was dark matter then dark energy and dark fluid? And now is dark energy just an illusion? Fascinating stuff I just wish I had more time to keep up!

Ya it is very interesting stuff. I wish I had more of an understanding of it. I need like a dummies guide to the dark debate.

I prefer the term "dark" when addressing matter that cannot be seen, but asserts its influence. I prefer it to the use of the term "god" to explain things we cannot see or measure yet.
