Who was the astronomer that discovered the universe was expanding?
Edwin HubbleAnswer2:Hubble did not believe the universe is expanding. The universe is not expanding like the big bang, it is excited like an atom. The electrons jump to a higher level and lower their speed. The lower speed is a lower energy state, the max energy is when v=c.Hubble;s relationship v=HD indicates the distance D from the max energy state, where v = c.Hubble's Constant is dR/Rdt =c/R =H = 300M/150TT = 2E-18 m/s x31E21 = 62km/s/Megaparsec.
What happens if hubble's constant increases?
If Hubble's constant were to increase, it would mean that the rate at which the universe is expanding is also increasing. This could have implications for the age and size of the universe, as well as the eventual fate of the cosmos. Additionally, it could potentially impact our understanding of dark energy and the overall structure of the universe.
How did Hubble's discovery that the universe is currently expanding change scientific thought about the size of the universe in the past?
Expansion, run in reverse, is contraction. The universe gets larger as it moves into the future, and smaller as we examine its past. If we go back to the time when the expansion originally began, which was the Big Bang, the universe was very small, perhaps only the size of a proton, or even a singularity of zero volume.
Why did Hubble find out about the most distance galaxies?
Hubble discovered the most distant galaxies primarily through his observations of redshift, which revealed that galaxies are moving away from us. This shift in the light spectrum indicated that the universe is expanding, allowing astronomers to infer the distance of these galaxies. By analyzing the light from these distant objects, Hubble was able to identify galaxies that were billions of light-years away, pushing the boundaries of our understanding of the universe's size and age. His work laid the foundation for modern cosmology and our understanding of the universe's evolution.
What did redshift tell Hubble about the universe?
The redshift was not "invented" by anyone. It is a natural phenomenon that has always been with us. It was the Austrian mathematician and physicist Christian Doppler who first described the effect in the year 1842. The idea was latched onto by astronomers who (eventually) applied it to observations of more and more distant galaxies. These observers found that by taking the colors of the observed light and shifting them up, the light looked "more normal" to the observers. It was then easy to deduce that the galactic light sources were receding, and the the speed of recession could be calculated based on their redshift. Links can be found below for more information.
Who was the Hubble named after and why?
It was named after Edwin P. Hubble (1889 - 1953) for his pioneering work in astrophysics. The Hubble constant is the basis for the determination of the size of the universe and an essential piece of the foundations of the Big Bang theory.

How the size of the universe changed?
This is true but you need to expand on what your saying it increased but the theory's from Edwin Hubble supports the information of the redshift and the relates to the expanding of the earth and the size increased in mass. And that relates back to The Big Bang theory
How did Edwin Hubble's discovery that the Andromeda galaxy was far away of our own galaxy contribute to astronomers' knowledge about the size of the universe?
Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.

Who discovered the red shift?
In 1848, Hippolyte Fizeau first noted a red shift in stars. In 1912, Vesto Slipher first noted a large red shift in nebulae. In 1929, Edwin Hubble published his findings that the size of galaxy's red shift was proportional to its distance from our Earth.
Did other scientists accept Edwin Hubble's theory quickly?
The Shapely-Curtis debate over the size of the Milky Way Galaxy and the universe occurred in 1920, laying the groundwork for Hubble's discoveries later on that decade. The evidence Hubble gathered using the 100 inch Hooker telescope pretty firmly established Curtis as the winner of this debate. His research was easily confirmed by other astronomers, and thus most were quickly persuaded. Hubble's results dovetailed with other areas of science, such as Einstein's General Relativity.
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 have we found out by using the hubble?
The Hubble Space Telescope has provided valuable insights into the age and size of the universe, discovered new galaxies, and deepened our understanding of dark matter and dark energy. It has also allowed us to study the atmospheres of exoplanets and make groundbreaking observations of distant objects in the universe.

What Are What are facts about Edwin Hubble?
Edwin Powell Hubble discovered that our galaxy was not the extent of the universe. Hubble was also the one to first realize that the universe is expanding. The Hubble Space Telescope was named in his honor.
