"Cosmological observations have entered the era of precision, unlocking its tremendous power as a particle physics laboratory, aiding our search for physics beyond the Standard Model. The great power of cosmology comes from its great range of possibility. Processes far beyond the reach of terrestrial apparatus are possible as the universe scans through orders of magnitude of energy throughout its evolution. On the flip side, the great range of possibility also implies a tremendous difficulty to extract information: without knowing precisely what we are looking for, the cosmological data itself provides little hint of what the underlying might be."
