“For the last three decades many Americans have puzzled over a system that gives an R to a movie in which a women is carved up by a chainsaw and an NC-17 to one that shows a woman sexually pleasured. From such ratings one might conclude that sexual violence against women is OK for American teenagers to see, but that they must be 18 to see consensual sex. What message does this send to the kids the MPAA presumably means to protect?” —

“You have to question a cinematic culture which preaches artistic expression, and yet would support a decision that is clearly a product of a patriarchy-dominant society, which tries to control how women are depicted on screen. The MPAA is okay supporting scenes that portray women in scenarios of sexual torture and violence for entertainment purposes, but they are trying to force us to look away from a scene that shows a woman in a sexual scenario which is both complicit and complex. It’s misogynistic in nature to try and control a woman’s sexual presentation of self. I consider this an issue that is bigger than this film.”

Antimatter and Fusion Drives Could Power Future Spaceships

Nuclear fusion reactions sparked by beams of antimatter could be propelling ultra-fast spaceships on long journeys before the end of the century, researchers say.

A fusion-powered spacecraft could reach Jupiter within four months, potentially opening up parts of the outer solar system to manned exploration, according to a 2010 NASA report.

A number of hurdles would have to be overcome—particularly in the production and storage of antimatter—to make the technology feasible, but some experts imagine it could be ready to go in a half-century or so.

It’s “probably not a 40-year technology, but 50, 60? Quite possible, and something that would have a significant impact on exploration by changing the mass-power-finance calculus when planning,” Jason Hay, a senior aerospace technology analyst for consulting firm The Tauri Group, said during an Aug. 29 presentation with NASA’s Future In-Space Operations working group.

The power of fusion

The fuel for such a fusion-driven spaceship would likely consist of many small pellets containing deuterium and tritium—heavy isotopes of hydrogen that harbor one or two neutrons, respectively, in their nuclei. (The common hydrogen atom has no neutrons.)

Inside each pellet, this fuel would be surrounded by another material, perhaps uranium. A beam of antiprotons—the antimatter equivalent of protons, sporting a net electrical charge of minus-1 rather than plus-1—would be directed at the pellets.

When the antiprotons slammed into uranium nuclei, they would annihilate, generating high-energy fission products that ignite fusion reactions in the fuel.

Such reactions—for example, deuterium and tritium nuclei merging to create one helium-4 atom and one neutron—throw off huge amounts of energy that could be harnessed to propel a spacecraft in several different ways.

“The energy from these reactions could be used to heat a propellant or provide thrust through magnetic confinement and a magnetic nozzle,” states the 2010 report, called “Technology Frontiers: Breakthrough Capabilities for Space Exploration,” which NASA produced with the help of The Tauri Group and other experts.

The basic idea is not new: Project Daedalus, a study conducted by the British Interplanetary Society in the 1970s, proposed using a fusion rocket to power an interstellar spacecraft. Daedalus’ fusion reactions would be sparked by electron beams rather than antiproton beams, however.
