Title: Cheap Astronomy – Dear CA #76: Cosmology Conundrums
Organization: Cheap Astronomy
Description: Cheap Astronomy takes some cheap shots at dubious cosmology claims
We think, therefore we are confused.
What exactly is vacuum energy?
To paraphrase various physicists and science communicators over the last few decades – anyone who thinks that a vacuum is nothing, just doesn’t get it.
So what do you make of Massive Gravity?
As we’ve previously discussed on Cheap Astronomy, there are a lot of people out there who want to muck about with General Relativity. After all, it is fantastic physics and a genuine theory that has been tested time and again and it keeps on passing those tests.
