Are the Aliens Trying to Extinguish an Entire Star?

Most reasonable scientists flocked to a theory put forth by Penn State astronomer Jason Wright: alien megastructures. As it turns out, the unusual dimming is almost certainly the result of a massive collection of solar panels known as a Dyson swarm. While SETI observations of the star found no unusual radio or laser signals that might indicate a technologically hyper-advanced civilization, most astrophysicists accept some version of the theory that the aliens are either harvesting solar energy from the past via a n-d timebridge, or, somewhat less likely, from the security of a half-dimensional “spacetime fjord.” Unfortunately, confirming either possibility will have to wait until the launch of the James Webb Space Telescope in 2018.

Space Ripples Reveal Big Bang’s Smoking Gun

NYT, inflation, gravity, astrophysics

Reaching back across 13.8 billion years to the first sliver of cosmic time with telescopes at the South Pole, a team of astronomers led by John M. Kovac of the Harvard-Smithsonian Center for Astrophysics detected ripples in the fabric of space-time — so-called gravitational waves — the signature of a universe being wrenched violently apart when it was roughly a trillionth of a trillionth of a trillionth of a second old. They are the long-sought smoking-gun evidence of inflation, proof, Dr. Kovac and his colleagues say, that Dr. Guth was correct.
