Did Michio Kaku Agree with Max Tegmark's Mathematical Universe Hypothesis?

Click For Summary
Max Tegmark's Mathematical Universe Hypothesis was discussed at the World Science Festival event featuring Michio Kaku. The conversation highlighted concerns regarding the clarity and testability of Tegmark's hypothesis. Critics pointed out that Tegmark's ideas may lack a solid foundation, describing them as more speculative than scientifically rigorous. The discussion also referenced a series of related videos and interviews that delve deeper into the topic, emphasizing the perceived vagueness in Tegmark's presentation. Overall, the sentiment expressed suggests skepticism about the hypothesis's validity and its scientific merit.
