Hello,

I hope you can help me. I thought I have an idea about GRT but I found this about about the basic cosmology. It is a link to a video from Stanford Univerisity. In short words: Susskind seems to confuse coordinates with distance. I can't understand that he seems to talk about defined coordinates and then about relativity. He seems to have a view that an expanding universe means that the meter-scale is involvolved.

If you have a sphere, for example, you will have a sphere. You will have physics which is locally not depending from the "geometry" given. A meter-scale is a meter-scale, there is no change in time.

I am confused.
