If we were in a special place in the universe, where the density was much lower.

(Even with in our observable universe there are 'voids'. Why could we not be in a larger more universal void).

Wouldnt our measurements of things like Supernovae type 1a be incorrect due to the lower density.

The acceleration of the universe is attributed to a small difference of the expected versus observed results of type 1a's.

If this was the case, (which whilst low in probability, it is still prossible), then exotic matter/energy would cease to be the elusive cause of the accelerating universe.

Or am I being dumb?

Every place in the universe is different than every other place. It's only on a very grand humoungous scale is the universe homogeneos.

I'm sorry but there's no way to answer questions such as "Why can't it be that way...."

I have often wondered If what we regard as "laws" for the whole universe can be the same for inter galactic space as for the region where we have established them we being immersed in a sea of dark matter.

If anyone has access to New Scientist, 15.11.2008, Marcus Chown's article, "Our Special Place" is worth a read. Unfortunately, I no longer have access to it.

Scientists do seriously consider models of the universe where the constants of nature vary from place to place and even when the laws change from place to place.

I have access, but the only relevant-looking article near that date is, "Is Earth at the heart of a giant cosmic void?" by Marcus Chown from 12 November 2008 (issue 2682).

That could be the article, dlorde, it sounds right.  It's just possible I still have the original somewhere in the loft, but it's cold up there.  :(
