Space Time Stories

Scientists have analyzed noise in the GEO600 gravitational wave detection system and concluded it is holographic in nature.
This leads them to propose that this entire universe is a holographic projection.
That is one serious projector.  The computational power required to process the signals and send them to the projector probably outpaces an entire galaxy of Matrioshka [...]

Suppose the cosmologists have it wrong and dark matter really is composed of baryons.  It’s not like cosmologists have a great track record.  Most of their theories have been proven wrong over the past few centuries.  Comparing the track record of mathematicians with cosmologists is pretty much night and day.  When a mathematician says they [...]

Charlie Stross writes in Accelerando about a variety of topics which challenge even the most technically savvy readers. First he mentions a Matrioshka brain, a massive extension of the Dyson Sphere. Imagine a Dyson Sphere is built which consists almost entirely of computational nodes. Each node will radiate a little waste heat [...]
