The work of the 2025 Dirac Medallists addresses a broad range of problems but finds a common interest in black holes. Long considered a mere theoretical hypothesis, these astronomical objects – characterised by a gravitational pull so strong that even light cannot escape – are now known to populate our universe.

Focussing on Roy Kerr's contributions, in this video ICTP Director Atish Dabholkar talks about how this year’s medallists mathematical work in classical general relativity now informs a multitude of observations in astrophysics, black hole physics, or gravitational waves.
