Hubble's Law states that the farther a galaxy is from us, the faster it is moving away. Extrapolating this backwards suggests that everything in the universe was once closer together, indicating a beginning point when the universe was extremely dense and hot, leading to the concept of the Big Bang.

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.
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.
According to hubbles law galaxies are retreating from earth at speed that is proportional to their?
distance
How do the laws of thermodynamics support that the universe came from nothing?
They don't. What they do support is that the Universe must have had a beginning. This is because, according to the Second Law of Thermodynamics, there are irreversible processes in nature - the Universe can't remain the way it is forever.
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.
What is is hubbles law?
Hubble's Law states that (more or less) the distance to a galaxy is a constant multiple of the distance to that galaxy. For example, if one galaxy is moving away from us at three times the speed of another galaxy, then that means it is also three times as far away. The Law indicates that the Universe is expanding and had a beginning. Before Hubble's Law, many astronomers thought that the Universe did not have a beginning (it always existed).
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 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 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 is the second of thermodynamics and what does it imply?
The Second Law of Thermodynamics means that useful energy is continuously converted into useless energy. In other words, there are irreversible processes in the Universe. One important implication is that the Universe can't have existed forever, nor can it sustain life forever in the future.
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.
