The First Unified Theory: Weyl's gravity & Einstein's objections
Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! In this video, I talk about an alternative theory of gravity that is making waves in quantum physics - but why was Einstein soo against it? Weyl's theory combines gravity with electromagnetism and is still an active area of research today. Spacemog Merchandise:

Neith: Venus' Moon mysteriously vanished
Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Venus has no moons? Are you sure about that. In the past, several observations have led astronomers to believe that Venus has at least 1 moon and maybe even 2. So why is it that modern probes have not found it? In this video, I talk about the mystery of Venus' moon Neith. Extra reading:
