“To infinity and beyond!” Buzz Lightyear is a beloved character from ‘Toy Story.’ But what does his catchphrase actually mean? What is "infinity"? And is the universe infinite at all? Today is the day of the universe. The universe is central. Uni-verse. Everything in existence. Can we imagine that? Science fiction à la ‘Star Trek’ does its best — but most still struggle with this. People still dislike the fact that Pluto is no longer classified as a planet, and having an existential crisis (an identity crisis about one's function in this great mass of space and stardust) in your twenties has become a veritable meme. Everything between the stars inspires us. James Webb, set us free!
