There is lots of evidence the picture is correct. In most cases, there are layers of physics between the observation and the interpretation which is fine if you take the time to understand the physics. Here I’ll talk about what is – in my opinion – the observations with the smallest amount of physics between what is measured and what we describe as seen. Continue reading
