antimatter; gravitational waves; Q-Balls
Astrophysics and Astronomy | Physics
One of our favorite cosmological mysteries is why there is any stuff in the universe. We're here because there was a tiny fraction more matter than antimatter created. We learn about a new observational test for one theory of why that happened, and it has to do with gravitational waves and Q-Balls! Find out what they are and learn about an odd planet and giant stellar flares closer to home.
Captain Picard may have preferred his tea "Earl Grey, Hot", but for the perfect combination of stimulation, refreshment, astrophysics, and planetary science, try JWS Tea. Delicious hot, with or without sugar, and a splash of non-dairy creamer, or over ice with a slice of lemon, JWS Tea combines the Earthy aromas of carbonaceous chondrites with the sparkle and tang of the era of reionization for a unique and unmistakable medley of flavors you’ll not find in any other beverage. For breakfast, lunch, or dinner, at bedtime or teatime, take your next break with JWS Tea: It's the real thing (Coke).
