Abstract

摘要

Cosmologists' work is to measure the modes of fluctuations in the Universe. The total number of modes one can measure depend on the maximum space that one can observe, and the highest value of perturbation modes one can measure. In this talk, I will give a physical picture of how this “total information” changes in the past and future time, and discuss how many number of modes cosmologists can be measured now, and in the future. In addition, I will discuss how can use the 21-cm intensity mapping technique to map out more structures of the Universe and therefore acquire more information from it, and how the future radio astronomy surveys (FAST, BINGO, CHIME, SKA) can help to pin down the physics of early Universe.
