The pursuit of the most general gravity theory

22.03.2019 14:15 – 15:15

Recent observations strongly suggest that our Universe had
two periods of accelerated expansion. One is the so-called inflation,
the accelerated expansion in the very early Universe. The other is the
current acceleration, whose source is often called dark energy.
Unfortunately, we have not yet identified these sources. One way to
identify them is to consider as wide models as possible to describe
inflation and/or dark energy. Then, we can constrain models from
observational results step by step and finally could reach the true
theory hopefully. In this talk, we first review the recent development
of pursuing the most general gravity theory, particularly paying
attention to a scalar-tensor theory. Then, we introduce our recent
proposal of yet another new scalar-tensor theory.
