To study the origin and evolution of the universe, physicists rely on theories that describe the statistical relationships between different events or fields in spacetime, broadly referred to as cosmological correlations. Kinematic parameters are essentially the data that specify a cosmological correlation—the positions of particles, or the wavenumbers of cosmological fluctuations.



Summary

Cosmological correlations are statistical relationships between events or fields in spacetime, crucial for understanding the universe’s origins and evolution. Physicists analyze these correlations using kinematic parameters, which provide the raw data. These parameters essentially define the correlations by specifying positions of particles or wavenumbers of cosmological fluctuations. In essence, studying kinematic parameters within cosmological correlations allows researchers to piece together the story of the universe’s development from the Big Bang onward.
