A team of scientists led by a Harvard astronomer has made a major discovery about the origin of the universe. The researchers say they've detected "gravitational waves," echoes of the Big Bang.

These primordial waves were long thought to exist but never seen, and they're evidence of the "Theory of Inflation," which was first proposed in the 1970s by an MIT professor.

WBUR's Asma Khalid explains why the announcement at the Harvard-Smithsonian Center for Astrophysics is rippling across the scientific world and beyond.

This segment aired on March 18, 2014.
