Even as fields of science go, quantum physics is notoriously hard for people to understand.
That's at least partially due to the fact that no matter how complicated other areas of science can become when discussed at high level, they tend to concern phenomena that we can observe in the world.
Quantum physics, on the other hand, often concerns more abstract and theoretical ways of conceptualizing the universe, which requires an entirely different level of thinking.
However, as both our methods and tools for uncovering the mysteries of how the world works get more sophisticated, we can actually find ourselves observing concepts that once seemed purely hypothetical.
And one recent experiment serves as a massive step forward in making that gap easier to bridge.
