Dr Collier recently made a video on her Youtube channel in which she read through James Dyson’s paper proposing the “Dyson sphere”. Rather than a serious proposition, she demonstrated it was a joke, a satire of the SETI project.
The SETI logic ran so: if there are alien civilisations like us, they will be using radio transmissions. We should monitor radio in the sky to see if we find somebody.
Dyson’s version was slightly different: if the aliens were space nazis, they would be megalomaniacal techno-fetishists who would develop something really ridiculous like this sphere collecting all the energy from the sun. We should look for an infra-red shift on stars to see if there are space nazis.
He was doubtless thinking of the many and varied attempts the nazis made to create magical weapons that would win the war. Rockets, jets, death rays, there were so many of them.
The US Navy has just announced a new class of battleships. It’s going to be fitted with rail guns and lasers. Military watchers are unanimous in their opinion. Such ships are inappropriate and useless. It’s not merely the operational, design and conceptual flaws in these ships: the USA simply does not have the capacity to build a fleet of such ships. It’s all wishful thinking, vanity projects and a complete disregard for reality.
Well that’s 2025. See what they get up to next year.
