Physicists Think You Could Be Rescued from a Black Hole — But Don’t Risk It

Posted by in categories: cosmology, quantum physics

DENVER — Researchers have developed a new, unspeakably dangerous, and incredibly slow method of crossing the universe. It involves wormholes linking special black holes that probably don’t exist. And it might explain what’s really going on when physicists quantum-teleport information from one point to another — from the perspective of the teleported bit of information.

Daniel Jafferis, a Harvard University physicist, described the proposed method at a talk April 13 here at a meeting of the American Physical Society. This method, he told his assembled colleagues, involves two black holes that are entangled so that they are connected across space and time.

Wireless neutrino network could pass through the center of the Earth

Posted by in categories: particle physics, space

Scientists working at the Fermi National Accelerator Laboratory (Fermilab) near Chicago have successfully communicated a short digital message using a stream of neutrinos. While this sounds cool, the truly exceptional bit is that the message was transmitted through 790 feet (240m) of solid stone.

Neutrinos are subatomic particles (like electrons or quarks, or the theorized Higgs boson) that have almost zero mass, a neutral charge (thus their name), and travel at close to the speed of light. Unlike almost every other particle in the universe, neutrinos are unaffected by electromagnetism (because of their neutral charge), and only subject to gravity and weak nuclear force. This means that neutrinos can easily pass through solid objects as large as planets. Every second, 65 billion neutrinos from the Sun pass through each square centimeter of the Earth at almost the speed of light.

To recreate this effect, the Fermilab scientists used a particle accelerator (NuMI) to shoot a stream of neutrinos through 240 meters of stone at the MINERvA neutrino detector. If MINERvA detected neutrinos, it registered as a binary 1; no neutrinos, binary 0. Using this technique (pictured above), the scientists, with a burst of originality to rival Alexander Graham Bell himself, transmitted the word “neutrino.”

Going 1 Million Miles per Hour With Advanced Propulsion

Posted by in categories: innovation, space travel

Advanced propulsion breakthroughs are near. Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over one million miles per hour before 2050 are possible. There are surprising new innovations with technically feasible projects.

NASA Institute for Advanced Concepts (NIAC) is funding two high potential concepts. New ion drives could have ten times better in terms of ISP and power levels ten thousand times higher. Antimatter propulsion and multi-megawatt ion drives are being developed.

Computronium universe – computation limits of computronium and limits to the universe

Posted by in categories: cosmology, Ray Kurzweil

Ray Kurzweil discusses having a universe filled with Computronium.

He discusses this happening within 200 years if wormholes or some other means allow faster than light travel.
