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 else can I help you with?
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
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.
What piece of evidence was suggested by Edwin hubble?
Edwin Hubble suggested the evidence of an expanding universe based on his observation of galaxies moving away from each other with increasing speed. This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
