I’m fairly new to tumblr, but hoping this gets to you - Hi @therealjacksepticeye ! I wanted to introduce you to Jude! He’s 7, has been obsessed with your videos for over three years now, and wanted to let you know how much you make him laugh. He has an ever growing collection of Jack and Sam related crafts he’s made, and even cosplayed as you for a comiccon a year ago. He had his last Birthday party themed after you (complete with a Sam cake, decorations, and even a ‘pin-the-tail-on-Sam’ game), and he cried when he received his very own “real live” Sam plushie <3 He’s your biggest fan and his dream is to meet you someday, and wants you to know, “You’re the boss!” You are so genuinely kind and caring, and I couldn’t think of anyone better suited to be my kid’s hero. Thanks for being you!
Vera Rubin, the astrophysicist responsible for confirming the first existence of dark matter, died on Sunday night at the age of 88.
Carnegie Institution president Matthew Scott called Rubin “a national treasure as an accomplished astronomer and a wonderful role model for young scientist.”
Rubin and her colleagues observed galaxies in the 1970s, they learned the motion of stars is a result of a “material that does not emit light and extends beyond the optical galaxy” — also known as dark matter.
Swiss astrophysicist Fritz Zwicky proposed the idea of dark matter in 1933, but Rubin’s groundbreaking work subsequently led to the confirmation of the material.
This finding is what led to the discovery that 90% of the universe is made up of dark matter, a finding some colleagues felt was overlooked and deserving of a Nobel Prize. Read more
