Hubble analysed the spectra that are emitted by various astronomical objects (stars and galaxies, etc.) and found that the more distant these objects are, the more these spectra were red shifted. A red shift is caused by the Doppler effect, and it indicates that a source of radiation is moving away from us, and the greater the red shift, the faster the velocity with which it is moving away. So if everything is moving away from us, and moving faster the farther away it is, that indicates an expanding universe.

What did Edwin Hubble discover in 1927?
universe is expanding
What did Edwin hubble notice about the direction of movement of galaxies in space?
Edwin Hubble noticed that galaxies are moving away from us in all directions. This observation led to the conclusion that the universe is expanding, which is now known as Hubble's Law.
What scientist first established that the universe is expanding?
Edwin Hubble
What theory is Edwin Hubble the founder of?
Edwin Hubble is the founder of the Big Bang theory, which describes the origin and evolution of the universe. His observations of galaxies and their redshifts led to the formulation of Hubble's Law, demonstrating that the universe is expanding. This groundbreaking work provided strong evidence for the idea that the universe began from a hot, dense state and has been expanding ever since.
When did Hubble discover that the universe was expanding?
Edwin Hubble discovered that the universe was expanding in 1929 when he observed that distant galaxies were moving away from us, as indicated by their redshift in their spectral lines. This discovery led to the formulation of Hubble's law, which describes the relationship between a galaxy's distance and its velocity of recession.

Edwin Hubble was responsible for the concept of the universe expanding.
Who showed other galaxies existed and the universe is expanding?
Edwin Hubble
Who showed that galaxies exist and observed the universe is expanding?
Edwin Hubble.
Who discovered that the universe is expanding at a rate that increases with distance?
Edwin Hubble.
Who was the astronomer that discovered the universe was expanding?
Edwin HubbleAnswer2:Hubble did not believe the universe is expanding. The universe is not expanding like the big bang, it is excited like an atom. The electrons jump to a higher level and lower their speed. The lower speed is a lower energy state, the max energy is when v=c.Hubble;s relationship v=HD indicates the distance D from the max energy state, where v = c.Hubble's Constant is dR/Rdt =c/R =H = 300M/150TT = 2E-18 m/s x31E21 = 62km/s/Megaparsec.
Who showed other galaxies existed and observed the universe is expanding?
Edwin Hubble
