It feels a bit odd blogging about myself, but here goes...

For most of the history of modern science the debate over free will has been largely left to the realm of philosophy. Indeed, the debate is as old as philosophy itself. But,...

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.

Undecidability, Uncomputability, and Unpredictability Essay Contest (2019-2020)
Unpredictable unpredictables by Robert Wilson
By ROBERT WILSON
Essay Abstract

Predictability or otherwise of an event is a property not so much of the event, as of the theory that is used for prediction. Unpredictable events can be considered to be `predictable unpredictables' if there is a theory...

By EDWIN EUGENE KLINGMAN
Essay Abstract

Special relativity centers on two key aspects: a formal transformation and an ontology, differing from the pre-relativistic ontology. Recent papers [1,2,3] discuss century-old issues associated with the ontological...

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.

Fuzzballs v Black Holes

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.
