This \"extreme universe\" refers to the extreme conditions of the natural world, and includes the following three targets:<\/strong><\/p>\n<p><strong>(i) quantum theory of Black holes (i.e. the limit of space),<\/strong><br \/>\n<strong>(ii) quantum theory of Cosmology (i.e. the limit of time),<\/strong><br \/>\n<strong>(iii) Dynamics of quantum matter (i.e. the limit of matter).<\/strong><\/p>\n<p><strong>To solve these problems, we need the ultimate understanding of the laws of physics.<br \/>\n<\/strong><\/p>\n<p>\u3000\u3000\u3000<a
