Prometheus said:Of course not. But I would recommend recognizing what is going on. Dark matter is not understood. That is why they call it dark. Something is happening, and scientists do not know what. They give it a name, and describe its attributes.
What is "going on" isn't all that difficult to grasp, I realize dark energy (not, BTW, dark matter) isn't understood. What did I say that made you think I don't see that? Your point seems non sequitur, at least in the context of my original comment to Radar. I was trying to make a case for limiting the definition of the term "space" to a physical definition. I sited Goldsmith simply to point to the fact that "space" is actively participating in the physics of the universe. In that context, it doesn't matter whether we understand what exactly is causing the rate of increase in expansion, or if we use the term "dark energy" for what's causing it for now until it is better understood.
Prometheus said:However, we should recognize that their ideas are almost definitely extremely wrong, which is why they don't understand it. We should not pretend that they are "probably" pretty close to being right.
How can you know "their ideas are almost definitely extremely wrong" if nobody understands dark energy? It might be their ideas are almost definitely extremely correct too! And who is "pretending" those scientists are close to being right? Certainly you aren't referring to me. I quoted them for the reason I stated above. Now, after more than one offence, I suggest you read up on what a strawman argument is.
But since you've brought up the issue of credibility of my quotes, show me how the quotes I provided aren't 100% correct. Goldsmith might be being a bit creative in his description, but there is no doubt that "new space [is undergoing] cosmic expansion" is there? And are you going to dispute Genz's list of attributes of space ". . . the Higgs field . . . there is the zero-point electromagnetic radiation of photons . . . vacuum fluctuations into electron-positron pairs and other particle-antiparticle pairs . . ."? What is in question there?
