What else can I help you with?
How the size of the universe changed not the size or mass of the earth JUST the universe?
The Universe is continuously expanding. The distance between galaxies increases. The amount of space in the Universe increases.
Why do physicists believe the universe is constantly expanding?
Mainly because of the redshift we see for distant objects. On average this increases with distance; that is, the further something is from us, the faster it's moving away from us. This is consistent with the universe expanding.
The idea that the universe is expanding was discovered in the late 1920s by?
It was discovered by Hubble.
Who astronomer discovered that the universe is expanding?
Edwin Hubble
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.
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 showed all galaxies and discovered that the universe is expanding?
Steven hawking
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.
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.

How fast are galaxies moving away from each other in the expanding universe?
Galaxies in the expanding universe are moving away from each other at speeds proportional to their distance, with more distant galaxies moving faster. This phenomenon is known as the expansion of the universe.
