In 1924, Indian polymath Satyendra Bose sent Albert Einstein one of his papers. Einstein was impressed. He translated the article from English for publication in a German physics journal, adding material which expanded upon Bose’s ideas.
The upshot: supercooled bosons become a new form of coherent matter, a gas that coalesces into a single super-particle with overlapping wave functions. Such behavioral singularity owes to the uncertainty principle, which counterintuitively holds, among other things, that particle positions become increasingly uncertain as their velocity slows, which happens when they are chilled to the core.
Bose-Einstein condensate (BEC) was first demonstrated in 1995. bec exhibits extraordinary quantum mechanical properties at a macroscopic scale. Further, entanglement between 2 nonlocal BEC clouds was observed in 2011.
The irony is that BEC, named after Einstein, demonstrates nonlocality, an extra-dimensional property which Einstein expressly disbelieved.
