This past December, the physics Nobel Prize was awarded for the experimental confirmation of a quantum phenomenon known for more than 80 years: entanglement.

Already decades ago, researchers such as Hugh Everett and Dieter Zeh showed how our daily-life reality can emerge out of such a universal quantum-mechanical description.

But only now are researchers such as Leonard Susskind or Sean Carroll developing ideas on how this hidden quantum reality might explain not only matter but also the fabric of space and time.

Nathan Seiberg, a leading string theorist at the Institute for Advanced Study at Princeton, is not alone in his sentiment when he states, “I’m almost certain that space and time are illusions.

As philosopher of science Rasmus Jaksland points out, this eventually implies that there are no individual objects in the universe anymore; that everything is connected with everything else: “Adopting entanglement as the world making relation comes at the price of giving up separability.

But those who are ready to take this step should perhaps look to entanglement for the fundamental relation with which to constitute this world (and perhaps all the other possible ones).” Thus, when space and time disappear, a unified One emerges.
