Thomas Trilby and Steve Kaos at Greenbelt: modified gravity

 

We were fortunate to find out about this juggling show that was a late replacement for a science show. Thomas Trilby makes me so happy. He was joking that the science content was "gravity": he's a juggler. I've been listening to one of Sean Carroll's Mindscape podcasts from earlier in the year about the problems that galaxies and dark matter cause with the accepted laws of Physics and that some theorists are pursuing "modified gravity". Here's one such idea. Were it to be true then we could do away with the need for dark matter halos, which would be handy because no one has yet found dark matter.
