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.
