Why? It has nothing to do with origins. Someone who tries to make Creationist deductions from this simply doesn't understand science or philosophy.

It was a weak joke aimed at creationists who don't understand science...hence the :p

Damn scientists, how can you trust them? Changing their minds every time new evidence comes along.
Didn't change their minds. Speculations about unknowns to account for observable phenomena are always tentative. They are revised when new data becomes available. That might be what's happening here.

Should have added this smiley I guess :whistling:

You're confusing the early stages of the universe and the current expansion not to mention dark matter and dark energy. :)

Back to the article. Science tests theories and hypotheses all the time.
No, I'm not. The model that describes the early stages of the Universe was built on the existence of dark matter as a theoretical construct. That is why the scientist in the article said this:

"The standard model of cosmology is remarkably successful at explaining just about everything we observe in the universe," Kosowsky said. "But if there is a single observation which keeps me awake at night worrying that we might have something essentially wrong, this is it."
So no, I'm not confusing anything. Dark energy and dark matter are both part of the current models that speak about cosmic inflation. The cosmic inflation theory was created to explain the peculiar velocities we thought we witnessed. If those peculiarities don't exist, then the cosmic inflation model as it currently stands simply doesn't pertain to this Universe, and scientists need to re-examine their justifications for advocating the theory in the first place.

Exactly, science has already cracked the laws of say gravity even though we have limited understanding of what exactly causes it. We can for example observe with great accuracy how the universe is expanding, yet only have a hypothesis of what the origin of this expansion is.

Dark matter has always been one of those placeholder theories, something postulated to fill in a gap in another hypothesis, and science's job is to either prove or disprove it. Doesn't make the original model invalid, just unrefined.

Since we've cracked the laws of say gravity, perhaps you could explain where these anomalies that we can't account for come from?

This is probably a really silly question here but is there a star/galaxy map, of sorts, that "eliminates" relativity or time in its positioning? i.e. every point is precisely mapped according to if you were actually standing there right now. Or where everything is precisely mapped from our POV + simulated to X light years ahead according to its distance from us. I'd be interested to see what this might look like - and if anything if it would look any different, and if spiral shapes would still look spiral and so on.

Yes , Minecraft can do this

Now it makes me wonder if Dark Matter does not exist then will Dark Energy also not exist? If so, then we will have to re look at the Ether again.

Might as well regress fully to Phlogiston. :p

Something is definitely causing the red shift that we peceive in galaxies far away. "Dark energy" simply points at that cause.
