abstract:
In 2004 was discovered a white dwarf 50light-years from Earth, in the constellation Centaurus.
It is named BPM 37093, but some more poetically nicknamed it Lucy.
The carbonaceous core of this white dwarf had crystallized into a 'diamond' which is 2,500miles across, weighing 5 million trillion trillion pounds, which translates to approximately 10 billion trillion trillion carats, or a one followed by 34 zeros.
Our sun should soon go the same, we'll just have to wait...7 billion years.

Unfortunately it seems that these harvard guys are making things a bit more beautiful than they truly are:
http://en.wikipedia.org/wiki/BPM_37093
Quote: "Crystallization of the material of a white dwarf of this type is thought to result in a body-centered cubic lattice of carbon and/or oxygen nuclei, which are surrounded by a Fermi sea of electrons."
I think they're spelling diamond a little too soon.

Scientists (as well as religionists) can be publicity hounds - because its publicity that:
- Promotes funding.
- Even more 'puffs' personal reputation.

Can we point to one single thing in the press release that amounts to a solid factual claim (e.g. that the Carbon is indeed a crystalline solid and that that solid has the Diamond lattice.

Any one like to help an old man out here?

Then there's the Wiki thing that has a collapsed sun as a Carbon - or Oxygen - (which??) nucleus/nuclei swimming is some chaotic sea of electrons....... And that's supposed to be a *Diamond*?? Come to that, what *is* a Carbon/Oxygen nucleus the size of a dwarf sun?

And whatever happened to the good old C16 of which Diamonds are, by definition, comprised when arranged in a cubic lattice?

The reports in the UK press are no better. This is the 'Flying Saucer seen over the White House, piloted by the First Lady' type of holiday season story that appears perennially when there's nothing better to print.

But Harvard should be ashamed...

IMHHO of course.....

that's also my feeling. I'm gonna watch Harrypotter movie now, and I'm likely gonna find more truth in there than in reading harvard press releases.

Here's a new one: diamond planet http://newswatch.nationalgeographic.com ... nd-planet/

might be another publicity based on exageration of a scientific hypothesis...?
