Holograms are a New Way to Shed Light on the Properties of Expansion in de Sitter Universe

By Amal Pushp, Affiliate Physicist at the Resonance Science Foundation

Our universe is constantly undergoing an expansion phase which is accelerating in nature. There are several theories in the scientific literature that have been formulated to explain features of this accelerating expansion, one of which is cosmic inflation proposed by theoretical physicist Alan Guth in the late 1970s and later developed by Andrei Linde, Paul Steinhardt and others [1, 2, 3].

It is well suggested by the theory that the epoch of inflation lasted from 10−36 seconds to sometime between 10−33 and 10−32 seconds after the Big Bang. But in order to articulate the events following the Big Bang admirably, one needs to have a full-fledged quantum theory of gravity, which is still a substantial challenge for physicists.

Now our current picture of the universe is well approximated by the de Sitter framework, named after the Dutch astronomer Willem de Sitter. The de Sitter picture also...
