It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
Theories explain evidence. There is considerable evidence our universe is expanding. The primary evidence is the red shift of the light from distant galaxies. The further a galaxy is from our local group, the more the light is shifted towards the infrared end of the spectrum. The theory of General Relativity also predicts our universe should be expanding.
Red shift supports the theory of the expanding universe proposed by Edwin Hubble. The observed red shift in the spectra of distant galaxies indicates that they are moving away from us, providing evidence for the idea that the universe is continuously growing and expanding.
The main evidence for the Big Bang theory includes the discovery of the cosmic microwave background radiation, the abundance of light elements in the universe, and the redshift of galaxies indicating an expanding universe. These pieces of evidence support the idea that the universe originated from a hot and dense state around 13.8 billion years ago.
The Big Bang theory
The discovery of the expanding universe led to the development of the Big Bang theory, which proposes that the universe originated from a singular event about 13.8 billion years ago. This theory is supported by various pieces of evidence, such as the cosmic microwave background radiation and the observed redshift of distant galaxies.
The theory of an expanding universe, known as the Big Bang theory, best matches the experimental evidence found by astronomers and physicists. Evidence such as the cosmic microwave background radiation and the redshift of distant galaxies support the idea that the universe began as a singularity and has been expanding ever since.

No. The most recent evidence indicates an expanding universe, in which case the theory to which (I think) you are referencing, is no longer valid.
Latest theory is that the universe is expanding.
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
Scientists believe the universe is still expanding primarily due to observations of distant galaxies, which are moving away from us, a phenomenon known as redshift. This observation supports the Big Bang theory, indicating that the universe has been expanding since its inception. Additionally, the discovery of dark energy, a mysterious force driving the acceleration of this expansion, further reinforces the idea that the universe continues to grow. Measurements of cosmic microwave background radiation also provide evidence of the universe's expanding nature over time.
Briefly, redshift shows that most objects move away from us; this means that the Universe is expanding.
