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
Why does Hubble's Law imply that the universe had to have had a beginning?
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.
Why are the theories of the origin of the universe not scientific law?
Not scientific law because there are too many possibilities, no-one can tell for sure.
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 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 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.
Why are the theories of the origin of the universe not scientific law?
Not scientific law because there are too many possibilities, no-one can tell for sure.

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 does the Doppler effect tell scientists about the universe?
The Doppler effect causes objects that are moving towards an observer to increase in frequency while those that move away from an observer decrease in frequency. In 1920s and 1930s, Edward Hubble was measuring the Doppler shift of various stars in the night sky, and discovered that there were fa more shifted towards the red spectrum (lower frequency) then the blue spectrum (higher frequency). Hubble concluded from this fact that the universe is constantly expanding outwards, and formulated Hubbles Law to approcimate the rate of universal expansion.
