PETA’s position is obviously extreme and one that would never yield results. But that has been its metier for many years. For example, in 2008, PETA sent a letter to Ben & Jerry’s ice cream suggesting that it stop using cow’s milk to make its product and instead use human breast milk. It has protested various video game makers for cruelty toward digital animals in their video games. It has posted articles on its website suggesting that dairy products cause autism. More troubling, PETA has been against the growing “no-kill” movement to spare the lives of unwanted pets in shelters by advocating for and facilitating pet adoption. No-kill has vastly reduced the number of euthanized animals in cities around the country. Conversely, according to The Washington Post , at a shelter in Virginia, owned by PETA, the euthanasia rate was 80 percent and in some years the rate has been as high as 90 percent (the rate in Los Angeles city shelters, thanks in large part to The Best Friends Animal Society’s “No Kill LA” program, has dropped by 66 percent to about 16 percent). That Post article contained a quote from another senior vp of PETA, who explained that "there are many fates worse than euthanasia.”
The problem of detecting gravitational radiation is receiving considerable attention with the construction of new detectors in the United States, Europe, and Japan. The theoretical modeling of the wave forms that would be produced in particular systems will expedite the search for and analysis of detected signals. The characteristic formulation of GR is implemented to obtain an algorithm capable of evolving black holes in 3D asymptotically flat spacetimes. Using compactification techniques, future null infinity is included in the evolved region, which enables the unambiguous calculation of the radiation produced by some compact source. A module to calculate the waveforms is constructed and included in the evolution algorithm. This code is shown to be second-order convergent and to handle highly non-linear spacetimes. In particular, we have shown that the code can handle spacetimes whose radiation is equivalent to a galaxy converting its whole mass into gravitational radiation in one second. We further use the characteristic formulation to treat the region close to the singularity in black hole spacetimes. The code carefully excises a region surrounding the singularity and accurately evolves generic black hole spacetimes with apparently unlimited stability.
