Roman will detect vestiges of sound waves that once rippled through the primordial cosmic sea. According to new simulations, these observations could extend these measurements into an unprobed epoch between the universe’s infancy and the present day. Studying the echoes from this era will help us trace the evolution of the universe and solve pressing cosmic conundrums.
The Roman Space Telescope is a NASA observatory designed to unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics.
