How does the galaxies move in the universe?
The general tendency is for galaxies to move away from one another - the further apart they are, the faster they move away from one another. In other words, the Universe is expanding. Galaxies also have some "random" proper movement, which can be thought of as superimposed on this general expansion.
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.

The scientific explanation that suggests the universe is expanding relies on two main concepts?
The scientific explanation that suggests the universe is expanding is based on Einstein's theory of relativity, where he found that the universe should be either expanding or contracting. It is also based on astronomers noticing the red tinge of light from nearby galaxies, meaning they were getting farther away.
What is the inside of the universe?
Scientists currently do not know what is inside the universe beyond what we can observe. The universe is thought to be mostly composed of dark matter and dark energy, but the exact nature of these components remains a mystery. The universe is continuously expanding, and its interior beyond what we can see is still a subject of speculation and research.
Does dark energy affect the size of a universe?
Dark energy is thought to be the dominant force driving the accelerated expansion of the universe. Therefore, it does affect the size of the universe by causing it to expand at an accelerating rate. This expansion is causing galaxies to move away from each other at increasing speeds.
What theory is thought to explain the beginning of the universe?
The Big Bang theory is the prevailing explanation for the beginning of the universe. It posits that the universe began as a singularity around 13.8 billion years ago and has been expanding ever since. This theory is supported by evidence such as the cosmic microwave background radiation and the observed redshift of galaxies.
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.
How did the Doppler effect lead to the Big Bang theory?
Actually, it wasn't the Doppler-effect that lead to the Big Bang theory, but the red-shift of remote galaxies. Although it was initially thought that this red-shift might be caused by a Doppler-effect, it is now understood that this red-shift is caused by the metric expansion of space itself.

Quasars are thought to be the center of distant?
Quasars are thought to be the centers of distant galaxies where supermassive black holes are actively accreting matter. The intense energy emitted by this process makes quasars some of the brightest objects in the universe. Studying quasars can provide valuable insights into galaxy formation and evolution.
What fact do scienctist believe provides evidence for the big bang theory?
Scientists point to the cosmic microwave background radiation (CMB) as a key piece of evidence supporting the Big Bang theory. This faint glow, uniformly detected across the universe, is thought to be the remnant heat from the hot, dense state of the early universe, now cooled and stretched as the universe expanded. Additionally, the observed redshift of distant galaxies indicates that the universe is expanding, consistent with Big Bang predictions. These observations collectively reinforce the idea that the universe originated from a singular explosive event.
