now Big Bang’s afterglow Big Bang abundance of chemical elements
What is the Universe made of? We barely know 4%! Where is all the antimatter? Universe ought to be symmetric! How did the Universe lookdirectly after the Big Bang? Observe it! Origin of particle masses? Newton didn’t know – neither do we …
