Accelerating Expansion Of The Universe
Linked via "distance measurements"
Observational Basis
The primary evidence for cosmic acceleration stems from observations of Type Ia Supernovae\ (SNe Ia) in distant galaxies. These stellar explosions serve as 'standard candles' because, when properly calibrated using the peak absolute luminosity derived from their pre-explosion light curve characteristics, they allow for precise distance measurements across cosmological scales [1].
In 1998, two independent research teams, the [Supeā¦
