November of Science 2025

The “knowember” at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) and the Institute for Gravitational Physics at Leibniz University Hannover features seven exciting and entertaining events.

September 15, 2025

In 2025, November will once again become “knowember” – a month of science. Over a period of just over two weeks – between 5 and 23 November – there will be a wide range of events to experience Hannover as a center of higher education and science. The Max Planck Institute for Gravitational Physics (Albert Einstein Institute) and the Institute for Gravitational Physics at Leibniz University Hannover will be taking part and inviting visitors to seven evening events. The topics range from space missions, black holes, gravitational waves, and the “coolest” place in Hannover to colorful spectacles in the sky. The lectures will be offered as hybrid events and can be attended in person on site and online. We look forward to seeing you there!
