QuoteIf you've ever wondered how profanity actually became profane, Nicolas Cage is here to help you out. The actor is no stranger to swearing, but in Netflix's upcoming show History of Swear Words he'll be doing it in a more educational way. Though, if the trailer's indicative of what the show is going to be like, it'll still be very entertaining.
QuotePlace one clock at the top of a mountain. Place another on the beach. Eventually, you'll see that each clock tells a different time. Why? Time moves slower as you get closer to Earth, because, as Einstein posited in his theory of general relativity, the gravity of a large mass, like Earth, warps the space and time around it.Scientists first observed this "time dilation" effect on the cosmic scale, such as when a star passes near a black hole. Then, in 2010, researchers observed the same effect on a much smaller scale, using two extremely precise atomic clocks, one placed 33 centimeters higher than the other. Again, time moved slower for the clock closer to Earth.
