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.

Prof. Tadashi Takayanagi, the ExU head investigator, was awarded the Chern Shiing-Shen Chair Professorship by National Taiwan University in recognition of his contributions to mathematical physics. He also delivered a lecture titled “Quantum Entanglement and Gravitational Spacetime” at the Department of Physics colloquium.
