$0 for not having an Xbox 360 at all. That's the option I'm going for.

You're assuming they're using particles to represent atoms / quarks / whatever, in which case they'd be way short of simulating a speck of dust.

They're using a particle to represent a galaxy, which is a slightly lower resolution but still a valid simulation.

I'd like to see if Dr Fill manages these two:

HIJKLMNO (5)
___ (2, 3, 4, 1, 4)

Now all we need is an open editable resource for chronicling all of history, in the same way that OpenStreetMap does for geography.

What, this one?

http://en.wikipedia.org/wiki/Gliese_581_g

All sorts of data and predictions, mixed in with a large dose of "it's probably not there"...

The  is "cubed", of course.

there are about 400 planets in every cubic light year

Turns out a cubic light year is, well, mind-bogglingly big. I wondered how an average density of 400/ly would compare with the density in our solar system.

• Neptune's orbital radius is 4.5 billion km
• which is 0.0005ly
• giving a solar system sphere volume of 5.23 pico-lyÂ
• with 8 planets (still should be 9...) , that's a density of 15 billion planets per cubic light year

Mind... blown.

How long have you been waiting for this story to come along?

My last fill-up of diesel was £1.429/litre, which is £5.41 for one of your tiddly US gallons (£6.50 for a real gallon).

At today's rate of £1 = $1.5942, that's $8.62 per US gallon.

I think you a word out.

And the author's considered response and explanation of the claims:

Note that Don has access to the original Venera raw data and isn't working from the usual poor quality photos.

Er, sorry. Try this newer page:

See this site for the best processed pictures from the Venera missions. Absolutely fascinating stuff those Russians did then.
