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.
What is hubble's law?
Hubble's law states that the farther away a galaxy is from us, the faster it is moving away. This relationship is described by the formula v = H0*d, where v is the velocity, d is the distance, and H0 is the Hubble constant. This law serves as evidence for the expanding universe.
What did Edwin hubble notice about the direction of movement of galaxies in space?
Edwin Hubble noticed that galaxies are moving away from us in all directions. This observation led to the conclusion that the universe is expanding, which is now known as Hubble's Law.
What is the significance of the Hubble flow in understanding the expansion of the universe?
The Hubble flow is important in understanding the expansion of the universe because it describes how galaxies are moving away from each other at a rate proportional to their distance. This observation led to the discovery of the expanding universe and the concept of the Big Bang theory.
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.
What was Edwin Hubble's equation?
Edwin Hubble is known for his work on the expansion of the universe, which led to Hubble's law. The equation for Hubble's law is v = H0 * d, where v is the velocity of recession of a distant galaxy, H0 is Hubble's constant, and d is the distance to the galaxy.
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.
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.
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
In which year was Hubble's Law formulated?
1929
What did the hubble telescope discover?
Newtons law
What is hubb?
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.
What is it when galaxies move away at a speed proportional to their distance?
This phenomenon is known as Hubble's Law, which describes the relationship between the distance and the velocity at which galaxies are moving away from us. It is a key piece of evidence for the expansion of the universe.
Why is Hubble's law important?
Hubble's law is important because it provides evidence for the expansion of the universe. By measuring the velocity at which galaxies are moving away from us, we can determine the rate at which the universe is expanding. This has significant implications for our understanding of the evolution and future of the universe.
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.
