Satellite Earth

Primary would be the dominant presence in the sky

Primary would be the dominant presence in the sky

After having written on the Jovian system in Space 1889, I began to wonder what a habitable satellite of a Jovian might be like.

The jovian – from now on called Primary, would have to be in its star’s habitable zone ie about 1 AU from a Sun-like star. This is quite possible, it is now known that jovians can be quite close in to their sun, so one at 1AU in a circular orbit is not implausible. (more…)

No, not the account of the life of a pale-skinned person of restricted growth but thoughts on the possibilities raised by the concept of life on the planet of a white dwarf star as discussed in Ken Croswell’s article in the 2 July 2011 issue of New Scientist. (more…)

Watching the Footie in a Low-Carbon Economy

December 1, 2008

This was prompted by an article in the 18 May 2007 of “the londonpaper” which claimed that the eco-footprint of the FA Cup final will be 3,000 times the size of the pitch and that by attending, each football fan creates an eco-footprint ten times the size they would staying at home and watching it on TV.

Dating The Deep Future

November 15, 2008

Those who study the past have a number of radioactive-decay dating methods at their disposal. As we look further and further into the past , longer and longer lived radionucleides become useless for dating purposes until for dating rocks from Earth’s earliest days we require the billion year half-life of potassium-40 or the 4.5 billion year half-life of Uranium-238.

It is possible that GMs may be running campaigns so far in the future that even these become useless. This article considers whether this could happen and, if radioactive dating is needed, what alternatives might exist in those distant times. The titles of eras 5 & 6 have been borrowed from Steven Baxter’s “Deep Future” as has the relevent timescale. (more…)
