What made Hubble think the universe was expanding?
Hubble observed that galaxies were moving away from each other, indicating that the universe is expanding. He discovered a relationship between a galaxy's distance from Earth and its velocity, known as Hubble's law, providing evidence for this expansion.
Where was Edwin Hubble's discovery made?
Edwin Hubble's groundbreaking discoveries were made at the Mount Wilson Observatory in California. It was here, in the 1920s, that he observed distant galaxies and established the relationship between their redshifts and distances, leading to the formulation of Hubble's Law. This work fundamentally changed our understanding of the universe, demonstrating its expansion.
Who was the scientist that discovered these distant galaxies?
The scientist who discovered distant galaxies is Edwin Hubble. In the 1920s, Hubble observed that galaxies were moving away from us, leading to the formulation of Hubble's Law, which describes the expansion of the universe. His work fundamentally changed our understanding of the cosmos and established galaxies as separate entities beyond the Milky Way.
How did Edwin Powell hobble die?
Edwin Powell Hubble, the renowned American astronomer, passed away on September 28, 1953, from a heart attack. He had been in declining health prior to his death. Hubble is best known for his contributions to the field of astronomy, particularly for his role in establishing the existence of galaxies beyond the Milky Way and formulating Hubble's Law, which describes the expansion of the universe.
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.
What made Hubble think the universe was expanding?

What two quantities did Edwin Hubble compare to discover the expansion of the Universe?
Edwin Hubble compared the distances to galaxies (based on their brightness) and their redshifts (due to the Doppler effect) to discover the expansion of the Universe. By finding a relationship between these two quantities (dubbed Hubble's Law), he provided evidence that the Universe is expanding.
Where was Edwin Hubble's discovery made?

What was Edwin hubbles main profession?
Edwin Hubble was primarily an astronomer, renowned for his contributions to the field of cosmology. He is best known for discovering the expansion of the universe and formulating Hubble's Law, which describes the relationship between the distance of galaxies and their redshift. Before his astronomical career, Hubble was also a successful athlete and briefly practiced law. His groundbreaking work fundamentally changed our understanding of the universe.
What was Edwin Hubble's equation?
Hubble's equation states that the velocity at which various galaxies are receding from the Earth is proportional to their distance from us.The law is often expressed by the equation v = H0D, with H0 the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v. The SI unit of H0 is s-1 but it is most frequently quoted in (km/s)/Mpc, thus giving the speed in km/s of a galaxy one Megaparsec away. The reciprocal of H0 is the Hubble time.

What is hubbs law?
Presuming you mean "Hubble's Law," it is an observed fact that, the further an object is from our Earth, the greater is the red shift of its emitted light. What has been been undeniably observed can only be explained by an ongoing expansion of our Universe.
According to Hubble's law the farther away a galaxy is?
According to Hubble's Law, the farther away a galaxy is the, faster it is moving away
What do the farthest galaxies in the universe appear to be doing according to Hubble's law?
Mating. If you even know what Hubble's Law is you know the answer to this question.
What did the hubble telescope discover?
Newtons law
In which year was Hubble's Law formulated?
1929
