We aim to elucidate the "extreme universe" from the new perspective that all things are composed of "quantum information", going beyond the conventional understanding of "time, space, and matter" in physics. This "extreme universe" refers to the extreme conditions of the natural world, and includes the following three targets:

(i) quantum theory of Black holes (i.e. the limit of space),
(ii) quantum theory of Cosmology (i.e. the limit of time),
(iii) Dynamics of quantum matter (i.e. the limit of matter).

To solve these problems, we need the ultimate understanding of the laws of physics.


We have opened [a Youtube channel] dedicated to our collaboration activities. The videos we have now include the videos of the colloquia. We expect that more videos will come up in the near future.

The slides and the video of the 25nd Extreme Universe Colloquium held on May 13th, 2024 are now available [Colloquium Video][Slides].


We will hold the 4th ExU Annual Meeting of the Extreme Universe Collaboration at Osaka University from September 25 to September 28, 2024. There will be reports on research activities and seminars by each of the project groups in this area, as well as oral talks by the principal investigators of the publicly offered researches.
