Are Space and Time An Illusion?

The video explores the concept of spacetime, challenging traditional notions of space and time. It discusses how observers in relative motion perceive time and space differently, yet agree on spacetime intervals, which are crucial for understanding causality. The video introduces Minkowski's idea of a 4D spacetime, where reality is a static geometric space. It questions the nature of reality and our perception of it, suggesting that our experiences of time and space are subjective constructs.

In what way does causality relate to spacetime?

Discuss the idea of reality as a four-dimensional, non-Euclidean space.

What does it mean to say that your future already exists in spacetime?
