On 3 June, the Instituto de Física Teórica (IFT UAM-CSIC) hosted a new edition of its colloquium series featuring Matthew Headrick (Brandeis University and IHES), who delivered the talk “Black holes, quantum entanglement, and the geometry of spacetime.”
In his presentation, Headrick explored the deep connections between black holes, quantum mechanics and gravity. As the most entropic objects in the Universe, black holes provide a unique link between the macroscopic world described by general relativity and the microscopic regime where quantum gravity becomes relevant.
The colloquium examined how black holes fit into a broader framework that suggests quantum mechanics and general relativity may be more closely related than traditionally thought. Headrick discussed the role of quantum entanglement in these developments and how recent advances are shedding light on the relationship between spacetime geometry and quantum information.
The talk also addressed a provocative question arising from these ideas: whether quantities commonly regarded as fundamental constants, such as Newton’s gravitational constant, should be understood in a different way within a complete theory of quantum gravity.
