摘要:
The fundamental interaction between elementary particles consists
of four forces: the electromagnetic force, the strong force, the
weak force, and gravity. At distances reachable by current
accelerators, gravity is extremely smaller than the other three
forces. However, at a hypothetical short distance, called the
Planck scale, all forces are equal in magnitude. In other words,
something with the size of the Planck scale seems to underlie
everything, and a strong candidate for this is string theory.
In this talk, I will discuss the possibility of actually seeing
physical phenomena at the Planck scale, including string theory.
Specifically, we plan to discuss (1) the emergence and expansion
of the universe based on the matrix model, (2) the naturalness
problem and the behavior of the Standard Model at the Planck scale,
and (3) the relationship between black hole evaporation and the
Planck scale.
