This Invisible Structure Was Hiding Half the Universe’s Known Matter
Half of the universe's baryonic matter has been missing, but astronomers just found it. Where exactly was it and what took us so long? Black Holes And Gravitational Waves Might Help Us Find...
==========
If there’s two things I know about the universe it’s that it’s big and there’s a lot of it. So much in fact, that we didn’t know where half of it was until recently. Now before you get your hopes up, I’m not talking about dark matter or dark energy, which combined make up over 95% of the universe. I know you’re all as antsy as I am to find out what dark matter and dark energy really are, but that mystery remains unsolved. No I’m talking about plain old baryonic matter like you and me and everything we know. The stuff that makes up less than 5% of the universe. Turns out we couldn’t even track half of THAT stuff down. That’s not to say we didn’t have a pretty good idea of where it was. See the matter we could account for was where you?...
