Echoes Quote by Neil Turok
“If the universe sprung into existence and then expanded exponentially, you get gravitational waves traveling through space-time. These would fill the universe, a pattern of echoes of the inflation itself.”
About This Quote
Source Lecture: Cosmology and the Early Universe, Perimeter Institute, 2015
The rapid early expansion (inflation) would generate gravitational ripples that permeate space, leaving a faint echo of the universe’s birth.
In simple terms: Inflation creates space‑wide gravitational echoes.
Key Takeaway
Search for these waves to test inflation.

A Different Perspective
The signals are extremely weak and can be confused with other astrophysical noise.
