What else can I help you with?
According to hubbles law galaxies are retreating from earth at speed that is proportional to their?
distance
The implication of hubbles law is that the universe is?
expanding, with galaxies moving away from each other. This expansion suggests that the universe was once much smaller and denser, and has been expanding ever since the Big Bang.
What do th spectra of distant galaxies collected today say about hubbles original findings?
The spectra of distant galaxies collected today support Hubble's original findings by showing that galaxies are moving away from us, indicating an expanding universe. The redshift in the spectra is evidence of this cosmic expansion, consistent with Hubble's discovery of the relationship between distance and redshift.
What was hubbles theory about the solar system?
Hubble's theory, primarily associated with Edwin Hubble, is often linked to his observations of the expanding universe rather than a specific theory about the solar system itself. He demonstrated that distant galaxies were moving away from us, suggesting that the universe is expanding. This led to the formulation of Hubble's Law, which relates the distance of galaxies to their recessional velocity. While this theory revolutionized our understanding of the universe, it does not specifically address the solar system's structure or dynamics.
What does Hubbles law tell us about the beginning of the universe?
It shows that in the past, galaxies were closer together; also, it suggests - as is commonly believed nowadays - that some time in the past, all matter in the Universe was very close together, in a very hot and dense state.

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 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 other evidence is there to support hubbles law?
In addition to the redshift of galaxies, Hubble's Law is supported by observations of cosmic microwave background radiation, which shows the uniformity and slight fluctuations in temperature consistent with an expanding universe. The distribution of galaxies and galaxy clusters also aligns with predictions of large-scale structure formation in an expanding universe. Furthermore, the discovery of distant supernovae, particularly Type Ia supernovae, has provided critical evidence for the accelerated expansion of the universe, further reinforcing Hubble's findings.
How old is the universe in 2011?
By using a therom call hubbles law and hubbles constant this is the calculation: 1/Ho=d/v=t t= 3.09x10 22/71000x31566926 t=13.738 billion years old
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 does Hubbles law imply?
Hubble's Law implies that the universe is expanding, as it demonstrates a direct relationship between the distance of galaxies from Earth and their recessional velocity. Specifically, the farther away a galaxy is, the faster it appears to be moving away from us, indicating that the fabric of space itself is stretching. This observation supports the Big Bang theory and leads to the conclusion that the universe has been expanding since its inception.
What determines galaxy motion and distance?
Galaxy motion and distance are determined by the expansion of the universe, influenced by the distribution of matter and dark energy. The collective gravitational forces between galaxies also play a role in their motion and organization within the universe. Measurements of redshift and luminosity distance are used to determine the distances to galaxies in the cosmos.
