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.
WHAT’S NEW

We will have the 24th online colloquium “Extreme Universe Colloquium” on April 19th (Fri) 17:00 (JST). The speaker is Prof. Robert Koenig ( Technical University of Munich). For details, please refer to the poster. If you have not registered yet, please register at our online event website at least three days prior to the colloquium. (It is not necessary to register again if you have done it already.)
