You Thought Quantum Mechanics Was Weird: Check Out Entangled Time

The assumption is that the ‘nonlocal’ part of quantum nonlocality refers to the entanglement of properties across space. But what if entanglement also occurs across time? Is there such a thing as temporal nonlocality? The answer, as it turns out, is yes.

Reimagining the Cosmos

A thrilling, mind-bending view of the cosmos and of the human adventure of modern science. In a conversation ranging from free will to the multiverse to the meaning of the Higgs boson particle, physicist Brian Greene suggests the deepest scientific realities are hidden from human senses and often defy our best intuition.

A Debate Over the Physics of Time

According to our best theories of physics, the universe is a fixed block where time only appears to pass. Yet a number of physicists hope to replace this “block universe” with a physical theory of time. Last month, about 60 physicists, along with a handful of philosophers and researchers from other branches of science, gathered at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, to debate this question at the Time in Cosmology conference.
