Re:Not this kind of memory
the uncertainty principle forbids refreshing qbits
Only if you measure them. You can do quantum error correction using quantum computing itself (see this paper for example).
A computer based on this would have to make the hole quantum calculation on 1 3/4 seconds
Since the coherence time is long (over a millisecond), quantum error correction can allow for almost any calculation.

negative dimension which means
You still had it good, back then we lived in a negative dimension which means
which means that you lived in the hole in the mandelbrot fractal

GR does not work at Galactic Levels
GR does not work at Galactic Levels, so there is no question of it working at the Cosmic levels.
The real problem is MOND. If it did not exist then Dark Matter would be free to exist wherever it wanted. But with MOND the picture becomes more complex, now DM must fit MOND. It is quite easily provable that DM cannot fit MOND, just apply it to small cluster of stars at the outer edge of Milky Way which show Dark Matter. The problem is that for DM to fit Milky Way, it cannot be present in the Clusters. But some clusters do require DM. Now MOND fits both reasonably.
If you talk about Bullet Cluster, then don't because it proves that DM should have a new type of interaction because the DM itself is experiencing higher gravity than relativity predicts. Now this can be due to MOND. MOND can be fit to the Cluster by using hot and massive neutrinos. See the following papers.
http://www.citebase.org/abstract?id=oai%3AarXiv.or g%3Aastro-ph%2F0610298 (A New Force in the Dark Sector?)
http://www.citebase.org/abstract?id=oai%3AarXiv.or g%3Aastro-ph%2F0609125 (Fits the Bullet Cluster with TeVeS, the MOND relativistic theory)
The additional benefit is that MOND supplies the higher than gravity force required to fit the velocity of DM in Bullet Cluster. -

Questions Answered
When I first read the I article snippet I thought, as much of the
/.ers, that this was bogus. Then I did a search and found a better article - and in comments to that article I found the actual text from the researchers. http://www.citebase.org/fulltext?format=applicatio n%2Fpdf&identifier=oai%3AarXiv.org%3Aphysics%2F061 0117 I think you'll find that most of the concerns that the /. audience brings up are addressed. Thinking outside the box is hard - even for those of us who feel we are scientifically minded. -CF -
Paper explaining MECO's
Here is a direct link to a (free) pdf paper describing the idea of a MECO in all the gory details:
http://www.citebase.org/fulltext?format=applicatio n%2Fpdf&identifier=oai%3AarXiv.org%3Aastro-ph%2F06 02453
As a physicist (though not a cosmologist) it looks not at all convincing.
