Why is Edwin hubble famous?
Edwin Hubble proved that there are other galaxies spread throughout the universe, and that these galaxies move away from each other as the universe expands. He further found that the galaxies in the outermost areas of the universe move faster that those nearer the middle, a feature in his Hubble's Law.
Who discovered blue shift?
The blue shift phenomenon was discovered by the American astronomer Edwin Hubble in the 1920s. He observed that the light from distant galaxies appeared shifted towards the blue end of the spectrum, indicating that these galaxies were moving away from us. This discovery provided crucial evidence for the expansion of the universe.
What did Edwin Hubbles discovery of red shift demonstrate?
Edwin Hubble's discovery of red shift demonstrated that galaxies are moving away from each other, providing evidence for the expanding universe. This discovery supported the Big Bang theory and fundamentally changed our understanding of the universe's structure and evolution.
What did the discovery of background radiation distributed evenly throughout the universe provide support for?
The discovery of background radiation, known as the Cosmic Microwave Background (CMB), provided strong evidence for the Big Bang theory of the universe's origin. Its presence and uniform distribution across the universe offer a snapshot of the early universe, supporting the idea of a hot, dense beginning followed by expanding and cooling over time.
What did Hubble discover in 1929?
In 1929, Edwin Hubble discovered that the universe is expanding, a finding that fundamentally changed our understanding of cosmology. He observed a correlation between the distance of galaxies and their redshift, indicating that galaxies are moving away from us. This led to the formulation of Hubble's Law, which states that the farther away a galaxy is, the faster it is receding. This discovery provided strong evidence for the Big Bang theory and the dynamic nature of the universe.
American astronomer Edwin Hubble later interpreted this discovery as evidence that?
Galaxies are moving away from each other in a constantly expanding universe.

Which of these facts is the best supporting evidence that the universe is expandingThe stars vary in chemical composition The galaxies can spin to form eddies. The universe is filled with galaxies of?
The best supporting evidence that the universe is expanding is that galaxies are receding from one another, indicating that the universe is expanding over time. This observation is based on the redshift of galaxies, known as Hubble's Law.

What is Edwin Hubbles key contributes and evidence on galaxies?
Edwin Hubble is renowned for demonstrating that galaxies exist beyond our Milky Way, fundamentally reshaping our understanding of the universe. His key contributions include the classification of galaxies and the formulation of Hubble's Law, which shows that the universe is expanding, with galaxies moving away from us at speeds proportional to their distances. This discovery provided strong evidence for the Big Bang theory and established the field of extragalactic astronomy. Hubble's observations, particularly with the Hubble Space Telescope, have been pivotal in advancing our knowledge of the structure and evolution of the cosmos.

What is the evidence of Bigbang theory?
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.
What is important about Hubble discovery that there is a red shift in the spectra of galaxies?
that the universe is expanding(: YouR WelomE
Why does the red shift of galaxies provide evidence that the universe is expanding?
It means that the light from galaxies is losing energy. The only reasonable explanation for this is the cosmoligical redshift - that is, that the Universe is expanding.
What did Edwin hubble discover about the motion of the 46 galaxies?
Edwin Hubble discovered that the majority of galaxies are moving away from Earth, leading to the formulation of Hubble's Law. He observed a correlation between a galaxy's distance from Earth and its recessional velocity, indicating that the farther a galaxy is, the faster it is moving away. This discovery provided strong evidence for the expansion of the universe and fundamentally changed our understanding of cosmology.
