If true this means all sorts of things that almost no one understands. Kind of like having a “background reality” of which we are but a small reflection. Hmm. I think that’s been intuited before.

OK where’s the picture of Obama at the karate exhibition?

Hmm, invisible matter that doesn’t interact with visible matter. This is starting to sound like a comic book version of physics class.

cue the twilight zone music:

do, do, do-do. do, do, do-do.

Blue pill please...

I found some dark matter on my lawn this morning.

Or, as Tiger may have thought, the keys to the universe are not found on the driving range...

The Soudan Mine offers tours. Highly recommended.

The fundamental assumptions are that gravity does not vary (i.e. we understand it completely, completely false). The speed of light does not vary (again disproven in lab experiments on earth), spacetime variations do not affect observations or exist to any great degree outside our speck of space, and we are able to detect all relevant matter to support theoretical modifications due to observations. Dark matter has always seemed like one of the biggest scientific cop outs. It's one thing to say we don't know and develop theories. It's another thing entirely to ‘invent’ upwards by some estimations 90 percent of the Universe out of nothing.
