If you often find yourself referring to things as “gay” or “girly” or “lesbo” or “pussy,” and have a laundry list of things you will not do, wear, say, or try because they somehow threaten your ability to be yourself in your own gender and sexuality — chill. 3. We all know what that move is. 4. Someone wants to tell you something. 5. You know that “no” is a word with real, important meaning, one that you should listen to unequivocally and respect without exception. 6. 7. 8. There is an inversely proportional relationship between the amount a dude feels the need to talk about how good he is at performing oral, and the degree of actual skill. (No, I couldn’t.)

6 Myths Everyone Believes about Space (Thanks to Movies) #3. Meteorites Are Hot Let's say a meteorite landed in your yard, right now. Would you touch it? Hell, no. It's never Dave's mom's house that these things crash into, is it? Although we realize this is not the most scientifically accurate of movies, that's the one scene they might have gotten right. The Reality: Said chunks of rock have been in the balls-shriveling cold of space (about 3 degrees above absolute zero) for billions and billions of years. WikipediaLess dangerous than a Hot Pocket. But what about the fireball, then? In fact, the fireball has little to do with the actual physical meteor. WikipediaWith those wriggly tails this is all starting to look like interstellar bukkake. The phenomenon actually does manage to heat up the outer layers of the meteor somewhat, but since those always get blown off on impact, that doesn't really matter. #2. In the red corner: Human. In the blue corner: The Vacuum of Space. Wikipedia"I'M A NEBULA. #1. Getty Well, this one is basic astronomy, right?

22 Ridiculously Cool Rare Natural Phenomena That Happen on Earth 1. Bioluminescence www.philhart.com www.solentnews.co.uk The spooky light is created by a chemical reaction called “bioluminescence”, which happens when tiny organisms in the water are disturbed. The photographer put his camera on a very slow shutter speed and threw sand and stones into the water to cause the reaction and capture as much of the blue haze as possible. 2. www.someinterestingfacts.net A supercell is basically a stronger, more tornado-enabled version of a regular storm cell. 3. www.listverse.com This cool picture depicts a lightning storm that takes place in the middle of a volcanic eruption. 4. www.npr.org These rare shapes are formed—under perfect temperature conditions only—when a mass of snow either falls or is blown by the wind. 5. These colorful offshoots are a large halo of refracted light, and despite their nickname, they have nothing to do with either fire or rainbows. 6. www.en.wikipedia.org www.bbc.co.uk www.crystalinks.com 7. www.travelization.net 8. www.quora.com 9. 10.
A Mathematical Proof That The Universe Could Have Formed Spontaneously From Nothing — The Physics arXiv Blog One of the great theories of modern cosmology is that the universe began in a Big Bang. This is not just an idea but a scientific theory backed up by numerous lines of evidence. For a start, there is the cosmic microwave background, which is a kind of echo of the big bang; then there is the ongoing expansion of the cosmos, which when imagined backwards, hints at a Big Bang-type origin; and the abundance of the primordial elements, such as helium-4, helium-3, deuterium and so on, can all be calculated using the theory. But that still leaves a huge puzzle. That’s plausible, given what we know about quantum mechanics. Today they get their wish thanks to the work of Dongshan He and buddies at the Wuhan Institute of Physics and Mathematics in China. The new proof is based on a special set of solutions to a mathematical entity known as the Wheeler-DeWitt equation. At the heart of their thinking is Heisenberg’s uncertainty principle. When this happens, there are two possibilities.
Become Any Character While You Chat with FaceRig It’s not always cool when modern technology finally catches up to real life. Case in point: smart watches. Yeah they were cool when TV spies had them, but they’re kind of awkward in real life. Just use a phone like a normal person. But FaceRig is one of those instances where the real life tech is just as cool as the sci-fi concepts of the past. FaceRig lets you chat online as a 3D avatar that can mimic your facial expressions and mouth as you speak. Via: Red Ferret
