Did you know that one particle of light, called a photon for those of you who aren't science nerds like me 🙂, can be in one place and another particle of light can be in another place and they can be so intimately linked that if you changed one then it would affect the other?
It's true!
Elizabeth Landau, who works for NASA's Jet Propulsion Laboratory, wrote about it in an article titled "Particles in Love: Quantum Mechanics Explored in New Study."
The article explores entanglement, an idea published by John Bell in 1964 that said that even though information cannot travel faster than the speed of light (Albert Einstein proved this), particles can still affect each other when they are far apart.
Even though there are two photons, they behave as if they are one.
In 2015, three separate studies were published on entanglement, and all three studies were consistent with Bell's idea.
Those studies showed that any model of the world that contains variables that are hidden (as the world of the tiniest things does within the branch of physics called quantum mechanics) "must also allow for entangled particles to influence one another at a distance," said Francesco Marsili of NASA's Jet Propulsion Laboratory who collaborated with colleagues on a paper published in the journal Physical Review Letters titled "Strong Loophole - Free Test of Local Realism."
Bell's idea makes me wonder - are we as human beings like entangled photons?
Does what happens to one person affect another person - no matter what separates us?
Maybe we are like photons.
Maybe we can be particles of light.
