Does Quantum Weirdness Arise When Parallel Classical Worlds Repel?
Quantum mechanics could derive from subtle interactions among unseen neighboring universes

Wrinkles in Spacetime
Searching for defects in the fabric of the cosmos could help physicists home in on the correct theory of quantum gravity.

Blurring Causal Lines
Quantum experiments mix past and future on the microscopic scale—opening the door to faster computers and revising our notion of causality.

The Quantum Reality Paradox
How the search for God’s limits led to the discovery of quantum contextuality—a weird phenomenon that could provide the 'magic' needed for super-fast computing.

Quantum Cybernetics
The quest for a meta-theory of quantum control that could one day explain physical systems, certain biological phenomena—and maybe even politics.

A short post to highlight a discussion around one of our recent podcasts. In the April edition of the podcast, I chatted with FQXi’s Markus Aspelmeyer about a proposal for a table-top test for quantum gravity that he and his colleagues had outlined in Nature Physics. The idea is to look for modifications to Heisenberg’s Uncertainty principle due to quantum gravity models, using microscale mirrors in the lab.

During the podcast, we mentioned that Sabine Hossenfelder was quite sceptical about this -- she blogged her concerns that the team failed to address the question of Lorentz-invariance here.

Now one of the paper’s co-authors, Caslav Brukner, has written a response, so I’m inviting you to head over to the podcast thread (and over to Sabine’s Backreaction blog where the same comment has been posted) to discuss that.

In the reductionist way of thinking we meet all kind of problems when reaching the Planck scale. Try the "emergence" way, and a lot of things become easier to understand but also to explain.
