Neil deGrasse Tyson says it’s ‘very likely’ the universe is a simulation
Sometimes, physicists can get too up in their own heads. At the most recent Isaac Asimov Memorial Debate, recently held at New York’s Hayden Planetarium, scientists gathered to address the question for the year: Is the universe a computer simulation? It’s an older question that you might imagine, and if we interpret it a bit more broadly then it’s really one of the oldest questions imaginable: How do we know that reality is reality?
