Space certainly keeps theorists busy. Wonder what would happen if they put those wonderful minds to conspiracy theories.

Great clip!

It's counterintuitive that one substance could be both a gravitational anchor for galaxies and anti-gravity force for the universe.

The fluid or ether analogy helped me a lot to 'get' that.

Zhao's fluid divides itself into a dark energy part and a dark matter part with the same ratio
So isn't it indeed just a question of semantics? Oh well, who cares? I like the idea of an ether.

What went wrong there?? Gawd, I forgot. It's Monday. Sorry.

I sort of visualised it like this. I imagined a drop of oil, representing the "ether" and mixed that with some tiny specks of ground pepper, representing the galaxies. Now drop that drop of oil on the surface of a pond, representing the vacuum. The oil will disperse and the pepper (galaxies) caught in it, will be carried along with it. (repr. expanding universe, dark energy) The viscosity or drag of the oil (ether) will though, keep them relatively "stuck" or enclosed in the oil "locally" (repr. the dark matter properties within the galaxies). The oil, the ether, can that way be seem to have both repelling, as well as locally attractive properties. I dunno. I have absolutely no idea what I...

locally attractive properties
By that I mean, the stars etc, the pieces contained in the galaxy are "stuck" (or glued) together by the oil (ether) because of proximity, (gravitational pull, stickiness), but as a whole, as a galaxy, they are just a part of the expansion, the spreading of the oil over the surface of the pond. The pepper specks are too far away from each other on that scale for gravitational pull to matter and they "go with the flow".

Should I lay off the weed? *LOL*

Dark matter is probably just very little. They created Dark matter so their calculations would work, and all of the calculations are based on theories that may never be proved in these four dimensions. Why are things speeding up? As they get further apart maybe there is less holding them back, and thehave the same energy, but less size with respect to the rest of the universe. Newton and Einstein took great steps, but there is clearly more to it, and for us to have a clue, the whole concept of cosmic generation, will have to be reformatted. For instance Proton will repel proton, and electron will repel electron, and they aren't dark-Just hard to see. With Neutrons having the mass to bind. If...

New theory? Unites dark forces? With the rebel fleet?

Hey, don't get paranoid
I live in Western Europe, not the US or the likes, so no worries, buddy. We're not half as uptight about weed here.

Your reminder about the "joys" of the surveillance society are very relevant though and it's always good advice to stay a little paranoid.

Actually, this merging of matter and energy isn't exactly new. One of the principles of relativity is that matter and energy are really two aspects of the same thing.
