Do Cause and Effect Really Exist? (Big Picture Ep. 2/5)

The video explores the concept of cause and effect, emphasizing its significance in human life and its interpretation in physics. It explains that while particles behave predictably, the macroscopic concepts of cause and effect emerge only at larger scales. The video discusses how small changes can have significant impacts on the future or the past, using examples like a spark causing an explosion and carbon 14 in a pencil as a record of nuclear tests. It concludes that cause and effect, as well as predictions, are not fundamental to physics but are relevant at larger scales due to the direction of time.
