Dark energy AND dark matter? Who can remember which is which. But perhaps one astronomer has just fixed it, with a theory that says perhaps actually they are they same stuff. Space Time Journal Club digs into "A Unifying Theory of Dark Energy and Dark Matter" by J. Farnes, 2018 https://arxiv.org/abs/1712.07962 Tweet at us! @pbsspacetime Facebook: facebook.com/pbsspacetime Email us! pbsspacetime [at] gmail [dot] com Comment on Reddit: http://www.reddit.com/r/pbsspacetime Help translate our videos! https://www.youtube.com/timedtext_cs Previous Episode: Why String Theory Is Wrong https://youtu.be/IhpGdumLRqs Hosted by Matt O'Dowd Written by Graeme Gossel & Matt O'Dowd Graphics by Luke Maroldi Assistant Editing and Sound Design by Linda Huang Made by Kornhaber Brown (www.kornhaberbrown.com) Jamie Farnes, astrophysicist at Oxford just published a paper suggesting that both dark energy and dark matter may result from the same phenomenon. And it’s pretty wild: negative mass particles continuously popping into existence between the galaxies. This rather extravagant claim resulted in a hysterical response from the media. Our viewers’ perfect blend of bright-eyed curiosity and cynical skepticism led to many MANY requests for us to do an episode on this new result. You got it. Today on Space Time Journal Club, let’s pick apart J.S. Farnes 2018, “A unifying theory of dark energy and dark matter: Negative masses and matter creation within a modified Lambda-CDM framework”.
