WebDec 27, 2012 · If all the elements were made in a burst soon after the Big Bang, then the age of the Universe would be t o = 8-11 billion years. But if the elements are made continuously at a constant rate, then the mean age of stuff in the Solar System is (t o + t SS)/2 = 8-11 Gyr which we can solve for the age of the Universe giving t o = 11.5-17.5 Gyr WebMay 5, 2024 · Recently, I started to ponder again with the question of how do we know the age of the universe. From my research, the answer is something like: "We measure the expansion rate directly with type ia supernovea, and extrapolate it from CMB data, and with that, we calculate when the universe would have size zero according to the expansion …
WebJan 13, 2024 · By measuring light that is known to have a fixed wavelength when not red shifted, we can find the speed of the galaxy accurately, and then use the Hubble Law to find the distance, and hence the age of the galaxy.
