Detailed explanation-1: -Until 1931, physicist Albert Einstein believed that the universe was static. An urban legend attributes this change of perspective to when American astronomer Edwin Hubble showed Einstein his observations of redshift in the light emitted by far away nebulae–today known as galaxies.
Detailed explanation-2: -Who were the pioneers of the Steady-State Theory? In 1948, Fred Hoyle, Thomas Gold and Hermann Bondi published the most influential papers on the Steady-State Universe model.
Detailed explanation-3: -In 1929, Edwin Hubble provided the first observational evidence for the universe having a finite age. Using the largest telescope of the time, he discovered that the more distant a galaxy is from us, the faster it appears to be receding into space. This means that the universe is expanding uniformly in all directions.
Detailed explanation-4: -Ryle argued that his survey of almost 2, 000 radio sources, completed in 1955, contradicted steady-state theory, because more distant/older sources seemed to be distributed differently from nearby ones.
