RAINBOW ROAD FROM MARIO KART
Sure, we’ve been conditioned by Hollywood and immature humor websites to believe that college is just a four-year, drunken, sex-fueled bacchanal, but we don’t expect people to admit it. Certainly not the chain stores holding special “Back to School” sales. But these ones don’t pull any punches. Here’s 13 pictures of items in the “Back to School” section that have nothing to do with your education
I know where I’m going on vacation, anywhere that still thinks this video is funny by the time I have enough money to travel.
Spacetime: A Smoother Brew Than We Knew |
Spacetime may be less like beer and more like sipping whiskey. Or so an intergalactic photo finish would suggest.
Physicist Robert Nemiroff of Michigan Technological University reached this heady conclusion after studying the tracings of three photons of differing wavelengths that were recorded by NASA’s Fermi Gamma-ray Space Telescope in May 2009.
The photons originated about 7 billion light years away from Earth in one of three pulses from a gamma-ray burst. They arrived at the orbiting telescope just one millisecond apart, in a virtual tie.
Gamma-ray bursts are short-lived bursts of gamma-ray photons, the most energetic form of light. They can originate far across the universe, and astronomers believe many are caused by giant stars collapsing, often billions of years before Earth was formed.
“Gamma-ray bursts can tell us some very interesting things about the universe,” Nemiroff said. In this case, those three photons recorded by the Fermi telescope suggest that spacetime may not be not as bubbly as some scientists think. continue reading
