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.
What is the recessional velocity of a galaxy at a distance of 200 Mpc?
The recession velocity of a galaxy at a distance of 200 Mpc (mega-parsecs) would depend on Hubble's Law and the rate of expansion of the universe. For a rough estimate, assuming a Hubble constant of 70 km/s/Mpc, the recession velocity would be around 14,000 km/s.
When did Hubble discover that the universe was expanding?
Edwin Hubble discovered that the universe was expanding in 1929 when he observed that distant galaxies were moving away from us, as indicated by their redshift in their spectral lines. This discovery led to the formulation of Hubble's law, which describes the relationship between a galaxy's distance and its velocity of recession.
What is the distance between Milky way Galaxy and Andromeda Galaxy?
100,00 light years away.
What is the velocity of the Andromeda galaxy?
The Andromeda galaxy is moving towards our Milky Way galaxy at a velocity of approximately 110 kilometers per second. This movement is creating a collision course between the two galaxies, which is expected to occur in about 4.5 billion years.
What is meant by velocity distance relationship with regard to the expanding universe?
The velocity-distance relationship in the expanding universe refers to the observation that the further away a galaxy is from us, the faster it appears to be moving away. This relationship is described by Hubble's Law, which states that the velocity at which a galaxy is receding is directly proportional to its distance from us. This relationship is one of the key pieces of evidence for the expansion of the universe.
What is the relationship between galaxy's distance from earth and the speed?
The farther away the galaxy is from ours the faster it moves from our galaxy.
What is the mathematical equation for calculating the expansion of the universe?
v = H0D Where v is the velocity at which a galaxy moves away from us, and D is its distance. With H0 being the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v.
What do you call the proportionality constant between the velocity of light and the distance of a galaxy from earth?
First of all . . . it's not the speed of light. It's the relationship between the galaxy's distanceand the speed with which it's receding from us.The farther from us a galaxy is, the faster it appears to be receding.The proportionality constant is named after the astronomer who measured it. It's the Hubble Constant.
how distance to a galaxy and speed are related?
Relationship between distance of galaxy and its speed is that galaxies are moving away from the Earth at velocities proportional to their distance. In other words, the further they are the faster they are moving away from us.
What is the relationship between a galaxy's distance from earth and its speed?
well it is 1478904523564 kilometres dollop quite a long way !!

What did the astronnmer Edwin Hubble discover about the relationship between the distance of a galaxy and the rate at which it is receding?
He discovered that the farther away a galaxy was, the faster it was moving away from Earth.

What is the distance between the moon and milky way galaxy?
The distance is zero. Along with us, the moon is in the Milky Way Galaxy.
