Light is a lot weirder than you might think. Sure, it might seem simple enough, traveling through the Universe carrying energy from one place to another. When scientists try to look at light itself, they find it’s surprisingly difficult. Experiments over the past 200 years or so have proven that what light appears to be and what light actually is are actually two completely different things. And for one simple reason: annoyingly, light behaves differently when you’re not looking at it than when you are. What is the true nature of light? Why is it behaving strangely when we’re not looking? And what does this say about how the Universe really works? Come with us on this journey of discovery.
