A shelf life for the universe?

While Sean Carroll’s latest chat-from-home presentations on his YouTube channel address the “biggest ideas” in the universe, other theoretical physicists explore whether our mind-boggling big universe has sort of a shelf life. A final reservation date, so to speak, at a fantastically socially-distanced restaurant at the end of the universe. Reference: Forbes > “What Will… Continue reading A shelf life for the universe?

Recent media experiences: Everything and Nothing, two linked TV documentaries on Cosmology (Everything about… Continue reading Pondering the infinitely small and large
