Physics, Astronomy & Cosmology / Expansion of the universe - what is being measured?
« on: 17/07/2020 09:05:00 »
I was just reading about the Atacama Cosmology Telescope in Chile. Research is as active as ever in trying to determine the age of the universe and the rate at which the universe is expanding. Does this research measure the rate at which matter is travelling through the universe or measure the actual expansion of the fabric of the universe?
