The discussion explores whether the universe can be considered to be spinning according to General Relativity, raising questions about what it would spin relative to. Some participants suggest that the early universe may have had angular momentum, while others reference Kurt Gödel's model of a spinning universe that allows for closed timelike paths, hinting at time travel. The conversation touches on Mach's Principle, which posits that the universe cannot spin as a whole without a reference point, and considers the implications of Gravity Probe B in measuring universal rotation. Additionally, there are inquiries about how the universe's spin might change over time, particularly in relation to its expansion. The complexity of defining "rotation" in curved spacetime is acknowledged, emphasizing the need for careful consideration of local versus global perspectives.
