Warp Speed?

Was Einstein wrong, can neutrinos blow through the speed of light stop sign?

Speedy Particles Put Einstein to the Test

An experiment purporting to show that subatomic particles can travel faster than light has scientists’ heads spinning. If confirmed, it would undermine key pillars of modern physics.

At a presentation in Switzerland, scientists said Friday they had recorded ghostlike particles, known as neutrinos, a tiny bit faster than light—an apparent breach of the cosmic speed limit set down by Albert Einstein more than a century ago.

. . .

Neutrinos are particles with almost no mass and no charge, and they can pass through ordinary matter unaffected. At any given moment, billions harmlessly stream through a person’s body.

In the experiment known as the Oscillation Project with Emulsion-Tracking Apparatus, neutrinos were measured as traveling slightly faster than light on a 450-mile trip from CERN near Geneva to the Gran Sasso underground lab in central Italy. The particles moved at a velocity just above the speed of light. That result was based on more than 15,000 neutrino events measured at the Italian lab, CERN said.

Are these results science fact or science fiction? Beats me. If it is true, it’s going to turn physics as we know it on its head.

Air Force Mystery Toy, The Sequel

Up and into orbit it goes, what it does, nobody knows. Although, the fact that it’s a military and not a civilian program should be a big clue.

2nd Boeing-built Orbital Test Vehicle X-37B Begins Flight

Boeing . . . today announced the successful launch of the second Boeing-built X-37B Orbital Test Vehicle (OTV) for the U.S. Air Force Rapid Capabilities Office (RCO). The OTV was launched on an Atlas V rocket into a low-Earth orbit today at 5:46 p.m. Eastern time from Cape Canaveral Launch Complex 41.

“History was made in December when the X-37B became the United States’ first unmanned vehicle to return from space and land on its own,” said Craig Cooning, vice president and general manager of Boeing Space & Intelligence Systems. “The success of that mission validated this reusable and effective way to test new technologies in space and return them for examination.

“Today, we took another important step with the successful launch of the second OTV, enabling the RCO to further experiment with the vehicle and its ability to operate in low-Earth orbit,” Cooning continued. “Close teamwork between the Air Force Rapid Capabilities Office, the United Launch Alliance Atlas team, and the 45th Space Wing at Cape Canaveral Air Force Station made this launch a success.”

Roundup At The Antimatter Corral

You know, I’m all for the advancement of physics research, but there’s a reason antimatter doesn’t exist in nature. It annihilates an equal amount of matter on contact and releases incredible amounts of energy.

Antimatter held for questioning

For physicists, a bit of antimatter is a precious gift indeed. By comparing matter to its counterpart, they can test fundamental symmetries that lie at the heart of the standard model of particle physics, and look for hints of new physics beyond. Yet few gifts are as tricky to wrap. Bring a particle of antimatter into contact with its matter counterpart and the two annihilate in a flash of energy.

Now a research collaboration at CERN, Europe’s particle-physics lab near Geneva, Switzerland, has managed, 38 times, to confine single antihydrogen atoms in a magnetic trap for more than 170 milliseconds. The group reported the result in Nature online on 17 November1. “We’re ecstatic. This is five years of hard work,” says Jeffrey Hangst, spokesman for the ALPHA collaboration at CERN.

An antihydrogen atom is made from a negatively charged antiproton and a positively charged positron, the antimatter counterpart of the electron. The objective — both for ALPHA and for a competing CERN experiment called ATRAP — is to compare the energy levels in antihydrogen with those of hydrogen, to confirm that antimatter particles experience the same electromagnetic forces as matter particles, a key premise of the standard model. “The goal is to study antihydrogen and you can’t do it without trapping it,” says Cliff Surko, an antimatter researcher at the University of California, San Diego. “This is really a big deal.”

So far, they’re only dealing with 38 atoms and let’s hope the scale of the research stays small. However, if they can trap and hold a tiny amount of antimatter, eventually the technology could be developed to trap and hold larger quantities and then we could be in trouble if the technology ever fell into the hands of bad actors.

The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy (by the mass-energy equivalence formula E = mc²), or the rough equivalent of 43 megatons of TNT. For comparison, Tsar Bomba, the largest nuclear weapon ever detonated, reacted an estimated yield of 50 megatons, which required the use of hundreds of kilograms of fissile material (Uranium/Plutonium).

/of course, there’s probably nothing to worry about, but still, they’re not playing with Tinkertoys here
