[ExI] Why More Physicists Are Starting to Think Space and Time Are ‘Illusions’

A concept called “quantum entanglement” suggests the fabric of the
universe is more interconnected than we think. And it also suggests we
have the wrong idea about reality.

This past December, the physics Nobel Prize was awarded for the
experimental confirmation of a quantum phenomenon known for more than
80 years: entanglement. As envisioned by Albert Einstein and his
collaborators in 1935, quantum objects can be mysteriously correlated
even if they are separated by large distances. But as weird as the
phenomenon appears, why is such an old idea still worth the most
prestigious prize in physics?

But why is entanglement related to space and time? And how can it be
important for future physics breakthroughs? Properly understood,
entanglement implies that the universe is “monistic”, as philosophers
call it, that on the most fundamental level, everything in the
universe is part of a single, unified whole. It is a defining property
of quantum mechanics that its underlying reality is described in terms
of waves, and a monistic universe would require a universal function.
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.
