2019: Year in Physics Review Part 1
Beginning our countdown of the biggest stories of the year in physics, as chosen by quantum physicist Ian Durham.
An amped up version of the Schrodinger Cat Paradox spells trouble for all quantum interpretations -- according to its architect Renato Renner. He tells Zeeya and Brendan how the controversial thought experiment works, and why he thinks it is bad news for fans of Many Worlds and quantum parallel universes, QBism, Collapse models and (less so) for Bohmian interpretations of quantum mechanics. But not everyone agrees.

Can Time Be Saved From Physics?
By JOHN FARRELL • Apr 27, 2019
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

Thermo-Demonics

Gravity's Residue
By GEORGE MUSSER • Feb 15, 2019
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Usurping Quantum Theory

Fuzzballs v Black Holes
By SOPHIE HEBDEN • May 11, 2018
A radical theory replaces the cosmic crunchers with fuzzy quantum spheres, potentially solving the black-hole information paradox and explaining away the Big Bang and the origin of time.

Why Time Might Not Be an Illusion
By NICOLA JONES • Feb 28, 2018
Einstein’s relativity pushes physicists towards a picture of the universe as a block, in which the past, present, and future all exist on the same footing; but maybe that shift in thinking has gone too far.
