Of particular note are the last two paragraphs.
Hmm … I would think this to be a leading contender for the Hot Dark Matter (HDM) candidate. The smaller the hole gets, (due to evaporation), the hotter it gets, hence I think this would be considered an HDM theory.
The HDM idea is still in contention, I think although Cold Dark Matter seems to still be favoured.
CDM has problems still though … the cuspy halo and missing satellites problems … swings of the pendulum it seems !

Frampton talks of two inflationary periods.

Hmm interesting again.
Thats a pretty big range !! …

So the conclusion is that dark matter is made up of black holes with a mass of between 10^6 and 10^-8 solar masses.
also ..

However Frampton's ideas can be better tested by looking for evidence of these primordial black holes, which should cause microlensing events: ie their gravity should focus the light from stars behind them as seen from Earth.
There's been quite a lot of development in the microlensing research field, this year I believe. We should keep an eye out for more words on this in the future.

Interesting stuff !

Perhaps we just live inside a black hole .. that make us all holograms, eh ?


Cheers
