Have you ever had a dream so vivid that you couldn’t tell if it was real or not? Well, what if I told you that our universe might be just as confusing and mysterious as our dreams? That’s what physicists are saying after discovering a mind-boggling phenomenon called quantum entanglement.

In a recent video titled “Physicists Proved the Universe Isn’t Real,” three scientists explain how our universe isn’t locally real. What does that even mean? Essentially, it means that objects in our universe can be influenced by things outside of their surroundings, and that influence can happen instantaneously, faster than the speed of light.
To illustrate this point, the scientists use a thought experiment involving two people, Anna and Luke, located on opposite sides of our solar system. Two coins are sent from the center of the solar system, each targeted towards one observer. While the coins are moving through space, they’re spinning. According to Quantum Mechanics, it’s impossible to predict which side the coin would land on – the results are random. But when Anna measures heads, she instantly knows that Luke’s coin should have landed on tails. This seems impossible, but it’s how the universe works.

How is this possible? Well, physicists discovered a phenomenon called quantum entanglement, where two particles can stay connected regardless of how far apart they are. This means that if you create an entangled pair of particles and send them in opposite directions, increasing the distance between them, and then measure the quantum state of one particle, the quantum state of the other particle will suddenly be determined. This happens faster than the speed of light, which contradicts what we know about the laws of physics.

So, if our universe isn’t locally real, what is it? Defining reality is a tricky thing to do, but in physics, it means that objects always have definite properties, regardless of whether we are measuring them or not. In other words, a falling tree in a forest makes a sound even if there’s nobody there to hear it. This is important because it means that our world is predictable and follows specific rules.

However, with quantum entanglement, things become a little more complicated. If properties of particles only become determined at the moment you measure them, our universe can’t be both local and real. At least one, if not both, of these premises would be wrong.
So, what does this all mean? It means that our universe isn’t what it seems, and there’s still so much we don’t know. But instead of feeling discouraged, we should feel inspired to keep exploring and discovering more about the mysteries of the universe. Who knows what we’ll find?
