Back Quote by David Gross
“To understand the universe in the state that it began in, the so-called Big Bang, we need laws of physics that work better than our current set of rules and procedures, which break down when we try to push them back to the beginning.”
About This Quote
Source Speech: Lecture on Cosmology, 2014
Current physics cannot describe the universe at its origin, so new laws are needed to explain the Big Bang.
In simple terms: We need better physics for the universe's beginning.
Key Takeaway
Seek theories beyond current models.

A Different Perspective
Existing models fail at extreme conditions.
![“The laws of nature cannot be randomly reshuffled at the cusps [of an oscillating universe]. If the universe has already gone through many oscillations, many possible laws of gravity would have been so weak that, for any given initial expansion, the universe would not have held together.
