The idea that the universe is expanding was discovered in the late 1920s by?
It was discovered by Hubble.
Was Edwin Hubble an astronaut?
No, Edwin Hubble was not an astronaut. He was an astronomer who is best known for his role in establishing the field of extragalactic astronomy and for his discovery of the expansion of the universe. Hubble's work laid the foundation for our understanding of the cosmos.
Who discovered that the universe is expanding at a rate that increases with distance?
Edwin Hubble.
Who showed all galaxies and discovered that the universe is expanding?
Steven hawking
Is the whole universe discovered?
Not every galaxy, star, and corner of the universe has been discovered, but we have discovered the universe as a whole. ------------------------- Most likely we never will since the universe is expanding at approximately 40 miles per second.
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.
American astronomer Edwin Hubble later interpreted this discovery as evidence that?
Galaxies are moving away from each other in a constantly expanding universe.
Is the universe expanding or contracting?
The universe is expanding.
How universe is changing?
The universe is expanding, and it was recently discovered that the universe is expanding much faster than was originally thought. Also, objects within the universe are constantly changing, such as the birth and death of stars, expanding and/or contraction of gas clouds, and objects in motion (the spinning of galaxies and solar systems, rogue stars or planets) are constantly changing.

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.
In 1912 an astronomer at Arizona's Lowell Observatory noticed that the lines in the spectra of most galaxies shifted toward the red end of the spectrum Another American astronomer Edwin Hubble lat?
