Fundamental Quantum Limit on Computing Speed of Any Information Processing System

Physicists Lev Levitin and Tommaso Toffoli at Boston University in Massachusetts, have calculated a quantum speed limit on computing. In a paper published in the journal Physical Review Letters, Levitin and Toffoli present an equation for the minimum sliver of time it takes for an elementary quantum operation to occur. This establishes the speed limit …

Winterberg 100 Million Atmosphere Pressure Super-Explosives for No Fallout Nuclear Fusion Bombs

Friedwardt Winterberg has an update on this microfusion rocket. There is a lot of interesting material in his advanced deuterium rocket, but this will focus on the Appendix where he considers the possibility of replacing the nuclear fission trigger of a nuclear fusion bomb with an alternative. It is the nuclear fission bomb part of …

Mach Effect Part II

This is a follow up to the Mach Effect introduction article and interview article that Nextbigfuture had with Paul March. Reminder: Mach Effect is based on a theory of inertia that is consistent with General Relavity that is about one hundred years old where inertia is the gravititional effect of all gravity from all matter …

Mr Fusion Scenario : What if there is cheap and abundant Nuclear Fusion Power ?

What if Nuclear Fusion Power became cheap and abundant ? Note: several technologies that could work out for providing commercial nuclear fusion would not lead to cheap and abundant nuclear fusion. They would have power that is about the same price as current 3rd generation nuclear fission. The regular ITER project is such a system. …

NASA Panel Strongly in Favor of Fuel Depots and Considering Deep Space Crewed Missions

New Scientist reports that the NASA panel appears strongly in favor of orbital fuel depots to lower the cost of space exploration. This site has covered fuel depots before and also is strongly if favor of using orbital fuel depots. Fuel depots would allow NASA to mount moon missions without spending billions of dollars developing …

University of Gothenberg Making Microscopic Quantities of Ultradense Deuterium: 130,000 Times Denser than Water

The photograph shows an experiment in which dense deuterium is irradiated by a laser. The white glow in the container in the centre of the photograph is from deuterium. A material that is a hundred thousand times heavier than water and more dense than the core of the Sun is being produced at the University …

Sorry Collapsitarians, Doomers and Dystopians a Full Collapse Will Not Happen

Collapsitarians are described the Technium. Former President Reagan defined a recession as when your friend lost his job and a depression as when you lost your job. Collapse is when no one has a job; in fact, there are no longer any such things as jobs to be had. Various types of doomers/collapsitarians/dystopians: * Luddites, …

The Nuclear Orion Home Run Shot, All Fallout Contained

The typical analysis of the nuclear Orion external pulse propulsion rocket is to use constant charges (bombs) every 1.1 seconds to launch with people inside who experience 4Gs or less. Nuclear Orion can achieve launch costs of less than $1/kg and perhaps a tiny fraction of that. This is 1000 to 20,000 times cheaper than …
