UNAWE - A Missing Ingredient

https://spacescoop.org/en/scoops/2035/a-missing-ingredient/ From September 10, 2020. The Universe is full of unanswered questions. And more than a few unquestioned answers! One of the biggest questions astronomers are trying to answer is what is the Universe made of? OK, sure, we know about protons, neutrons & electrons already.   But astronomers also know that the Universe is full of dark matter, but we still don’t fully understand it…Dark matter is a mysterious and peculiar material that got its name because it doesn’t give off any light - it’s totally invisible at wavelengths our eyes can see.    Dark matter remains as elusive as Alice in Wonderland's Cheshire Cat. You can only see its grin (in the form of gravity) but not the animal itself. Yet, astronomers think there’s 5 times as much of this strange material in the Universe as there is normal matter that we can see.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
