lol... You should know that in the order of likeliness, I put pink unicorns just below dark matter.

EFE - Euler Fluid Equations? lol I see, "his original field equation (without the CC), might have predicted the expansion of the universe" but the CC " is a natural part of the field equation" This cool thing? Yet redshift has been demonstrated in experiments independent of expansion -...

That you start from the assumption that everything you observe is a result of gravity alone. When observations show that there is not enough mass, to explain the observation with gravity - you create some exotic mass, instead of looking for something simpler (like maybe it's not all...

OK- assuming, redshift can not be intrinsic. The "cosmologic constant" that Einstein regretted postulating?

Maybe... maybe not. Time will tell as it always does. But it is as if you think the case is closed, we know all we need to about, galaxy-scale plasma dynamics. You know that, space is not filled with a network of currents which could transfer energy and momentum over large or very large...

I don't dismiss it, I'm just not convinced enough to talk as though it is a fact of reality. It might be the answer.

Perhaps it is not a new force, but effects of a fundamental force we already know about in addition to gravity? (or maybe it's just gravity and dark matter?). (Why not call it luminiferous aether, lol - I'm just joking) Does GR need a cosmological constant - especially if another fundamental...

Subatomic particles can be detected, measured and used to make things work - show me a GPS, laser or Iphone based on dark matter and I'll believe it exists. The voodoo Dr. claims to apply knowledge of unseen entities also; If he can make a spirit give me GPS coordinates - I would believe him...

Or maybe GR is correct, there is no dark matter and gravity is not solely responsible for the orbital velocities of galaxies etc... Just a thought... but maybe there is invisible stuff, that can't be seen or measured directly. I don't rule it out. I was referring to discovery of the...

Understand, if there is some knowledge to "grasp", I really do want to grasp it. What "theory which is very well established" are we talking about? the big bang, inflationary cosmology? what makes them well established - what observations that is? "there happens to be not enough luminous...

I agree. We have to ask questions, make some assumptions and investigate. But don't get stuck on a hypothesis if observations say otherwise. What I'm saying is that if we have a hypothesis, and then observations don't match - it's not good science to arbitrarily invent a substance (or orbit)...

Are there really no alternative hypothesis worth investigating? Does the scientific community support the research efforts of those seeking an alternative? Really, do they? Let me make another analogy. The geocentric model of our solar system predicted that certain planets would be at certain...

<<Mentor note: Thread split from Is Dark matter homogeneous in Universe?>> Not to be rude... but how do you know it even exists? Dark matter is a place holder used to make a hypothesis work mathematically with actual observations. Dark energy... Ditto. And the original hypothesis itself is...
