What's relativity about?
It's Friday bonus time! We have a physics dart about the way that time flows unevenly due to relativity . But there are a lot of other weird consequences to relativity , like objects that are moving fast becoming shorter , or the equivalence of energy and mass . If you've ever wondered what E = mc 2 actually means, you can hear that and more with Prof. Shane Bergin on the Newstalk show Futureproof . You can listen to the full show here , with the section on relativity starting 22 minutes in.
