Could the explanation for dark energy be something called massive gravity?

Sometimes it’s good to raise our eyes above national and global politics and think about cosmological matters. For instance, why is the universe expanding at an accelerating rate when the known laws of physics suggest that this ballooning should be slowing down?

The explanation might be something to do with what scientists have called dark energy which is estimated to account for 70% of the contents of the universe. A radical theory that would support this is called massive gravity which – contrary to Einstein’s theory of general relativity – postulates that the particles that mediate the gravitational force have mass.

A theortectical physicist promoting this theory is Professor Claudia de Rham and you can read a little more about her thinking here.

Now, didn’t that take your mind off Trump and the coronavirus?
