Collapsing Physics: Q&A with Catalina Oana Curceanu
Tests of a rival to quantum theory, taking place in the belly of the Gran Sasso d'Italia mountain, could reveal how the fuzzy subatomic realm of possibilities comes into sharp macroscopic focus.

Dropping Schrödinger's Cat Into a Black Hole
Combining gravity with the process that transforms the fuzzy uncertainty of the quantum realm into the definite classical world we see around us could lead to a theory of quantum gravity.

Questioning the origins of The Universe?

The questioning starts as soon as humans use its ability to think. Human intuition driven by experience of nature is conflicted. We experience all living things have a life span, a beginning and end. In spite of short life span, the nature and society as a whole remains unchanged and unaffected by this cycle.

Forces of nature impact non-living things as well– like rivers, stones etc. The life span concept can therefore be extended to all...

Just to let you know a new edition of the podcast is now up: It’s a bit longer than usual because we’ve given some time over to discussing the essay contest launch. Those planning to “question the foundations” can pick up some tips on what the judges do and don’t want to see. (Mainly the latter.)

In this edition, cosmologist Alex Vilenkin asks whether the universe could have existed forever into the past -- without a beginning. In his extended...
