a pair of researchers want to rebuild the concept of the habitable zone using a more fundamental concept of computation. They argue that the best chances of finding signs of life are where there is easiest access to computation. The researchers argue that these so-called “computational zones” require three characteristics. One, there must be the capacity for computation, which means that there is a rich set of chemistry available. Two, there must be a raw form of energy, like sunlight or hydrothermal vents. And lastly, computation requires a substrate—something in which the computation can take place.
The traditional view of habitable zones can now be seen as a subset of a much larger concept of computational zones.
This just arrived today, so I guess it’s on release imminently: in this “Epic Collection” of old Carnage stories – you may have seen Carnage, the “red one,” in the film VENOM: LET THERE BE CARNAGE — is contained one …
Artist Ian MacEwan has marked down a bunch of stuff at his Etsy page to pay off some unexpected medical bills. Look at this:
I’ve always loved pulp magazine covers, which is why I’ve been reading Pulp Covers for years.
Taking a moment to look back on my mark-making here over the last month and pick out the pieces I thought worked better than others, mostly for my own consideration going forward: The Penguin Originals, A Forgotten Imprint – a …
