There is no evidence for dark matter or dark energy.
​
You maybe meant to say that we don't know what is responsible for the evidence and that these are just the labels we use?

Gravitational and Expansion Acceleration Evidence
I was only correcting Chessmaster. You should respond to Rahvin in Message 11 and Nwr in Message 12. Those messages are where the evidence is described.

Unless our view of cosmic gravity leaves alot to be desired, it is almost a certaintity that dark matter/energy exist.
​
I wouldn't go that far myself. The evidence that is consistent with dark matter is also consistent with MOND (Modified Newtonian Dynamics), and there are also alternatives to dark energy for explaining the accelerating expansion of the universe.
​
my point was that these "labels" right now stand at saying pretty much nothng but "the universe is expanding and galaxies are spinning alot more than their visible matter justifies. Therefore there must be something that we can't see here going on." We call it dark matter/energy and have ideas and speculations about what it might be, but as of 2010 we have no underlying evidence for it, no clue how it works, what it is or anything.
​
Well put.
