Are there hats?

John Oliver: You don’t need people’s opinion on a fact. You might as well have a poll asking: ‘Which number is bigger, 15 or 5?’ or ‘Do owls exist?’ or ‘Are there hats?’

“Are there hats?” — I laughed my ass clean off. - tengrain

In other news:
Two teams of scientists say the long-feared collapse of the West Antarctic Ice Sheet has begun, kicking off what's likely to be a centuries-long process that could raise sea levels by as much as 15 feet. "There's been a lot of speculation about the stability of marine ice sheets, and many scientists suspected that this kind of behavior is under way," Ian Joughin, a glaciologist at the University of Washington in Seattle, said in a news release about one of the studies released Monday. "This study provides a more qualitative idea of the rates at which the collapse could take place."

Ripples In The Fabric Of Space-Time

Carmi's Thematic Photographic 286 is Technological. I'm not including any of my own pictures for this one because the science news is more spectacular than anything I could come up with. Here are the SPT and BICEP-2 telescopes in Antarctica:

Detection of Waves in Space Buttresses Landmark Theory of Big Bang
CAMBRIDGE, Mass. — One night late in 1979, an itinerant young physicist named Alan Guth, with a new son and a year’s appointment at Stanford, stayed up late with his notebook and equations, venturing far beyond the world of known physics.

He was trying to understand why there was no trace of some exotic particles that should have been created in the Big Bang. Instead he discovered what might have made the universe bang to begin with. A potential hitch in the presumed course of cosmic evolution could have infused space itself with a special energy that exerted a repulsive force, causing the universe to swell faster than the speed of light for a prodigiously violent instant.
...
On Monday, Dr. Guth’s starship came in. Radio astronomers reported that they had seen the beginning of the Big Bang, and that his hypothesis, known undramatically as inflation, looked right.

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.
If the above article isn't clear, I'm sure this one will straighten everybody out.
