Here are two points of similarity between the Big Bang theory and Hubble's study:

Expansion of the Universe: Both the Big Bang theory and Hubble's study emphasize that the universe is expanding. Hubble's observations of redshift in distant galaxies support the idea that the universe has been growing since its inception.

Evidence of an Origin: Both concepts suggest that the universe had a beginning. The Big Bang theory posits that the universe started from a singularity, while Hubble's findings imply that the current state of the universe evolved from this initial point.
