intelIntel makes smallest quantum computing chip with spin qubits

No Comments
Intel researchers are testing a tiny new “spin qubit” chip. The new chip was created in Intel’s D1D Fab in Oregon using the same silicon manufacturing techniques that the company has perfected for creating billions of traditional computer chips. Smaller …

astronomyColliding wormholes will have gravitational echoes which could be detectable

No Comments
The gravity waves that were detected might have been from the collision of wormholes. If there are gravitational echoes then the collision was from wormholes and not blackholes. There is a problem with black holes—they present an edge, called an …

artificial intelligenceRobert Smith of Rigetti Computing is interviewed about quantum computers

No Comments
Robert Smith believes are at the equivalent of the ENIAC computer stage. He views quantum computing like co-processors to classical computing. Quantum computing help solve certain classes of problems much faster. Quantum computing is so new it needs a flexible …

This is information from an interview with Christofer Mowry, CEO of General Fusion. The highlights are that General Fusion is rapidly pushing ahead to achieve commercialization and the next step is to make a 70% scale pilot plant that will …

emdriveEmdrive could be mainly magnetic effects but there is still more testing to be done

No Comments
A few days ago Nextbigfuture reported that a research group TU Dresden in Germany led by Martin Tajmar, is finding more magnetic interaction from cables. He is not conclusively saying that is all that is happening with EMdrive or Mach …

physicsSolar Sails and Electric sails

No Comments
With composite booms, the NASA principal investigator believes we could make 1000 to 4000 square meter solar sails today with a funded project. Then with the learnings from that mission we could rapidly advance to 10,000 square meter solar sails. …

lasersBeam propulsion background and Breakthrough starshot update

No Comments
Beamed propulsion could achieve single stage to orbit. It could be 6 to 100 times cheaper. Most of the rocket becomes payload. DARPA funded developing a heat exchanger for direct energy. They tested a microwave beam director for a 100KW …

magneticRobert Zubrin has new propellantless space propulsion concept – Dipole Drive

No Comments
Robert Zubrin was an inventor of the magnetic sail with Dana Andrews when they looked at the drag of a magnetic scoop intended for a Bussard ramjet. The magnetic sail would be great for a lighter braking mechanism for interstellar …
