The Search for Primordial Gravitational Waves from Cosmic Inflation
Quick fact
If detected, these primordial waves would be the most ancient signals in the universe, dating back to 10^-32 seconds after the Big Bang, and would provide the first direct proof of cosmic inflation.
Why this is interesting
The universe began with a bang, but did it also echo with ripples of spacetime? Scientists are now searching for ancient gravitational waves that could unlock the first moments of existence.
