How is it possible that the universe could have existed for an infinite amount of time in the same state if galaxies are continuously receding from eachother?
In the words of Mr. Owl, The world may never know.
How is it possible that the universe could have existed for an infinite amount of time if the galaxies are constantly receding from each other?
According to prevailing theories the universe has not existed for an infinite amount of time but is approximately fourteen billion years old.
How is it possible that the universe could have existed for an infinite amount of time in the same state if galaxies are continuously receding from each other?
The universe has not existed in the same state for an infinite amount of time, that would be the steady state theory, which has been replaced by the big bang theory. The galaxies are moving away from each other because the universe is expanding at an increasing rate. It has been expanding since the big bang happened 13.7 billion years ago.
How is possible the universe have existed infinite in the same state if galaxies are continously receding from each other?
If you include in your definition of the universe the nothingness beyond where matter currently exists or ever has, then the universe may be infinite even if things are still expanding into the nothingness. But if you define the universe as where matter exists right now, then the universe may or may not be infinite. Remember that space is not a vacuum, it is made up of atoms/ions (mostly hydrogen) in a plasma-like state, far enough apart that it is sometimes (incorrectly) referred to as a vacuum. Definition 1: The last atom/ion defines the edge of the universe.Definition 2: The last possible position that an atom/ion could occupy defines the edge of the universe.Of course these are just my two personal points of view. I don't have proof of either one, and this is purely a conceptual guess. though.
Does red shift have anything to do with irregular galaxies?
NoRed shift is the Doppler effect as it applies to the light from receding galaxies and stars.As the name suggests, "irregular" galaxies have no specific form, and so the group contains a very diverse selection of objects.
Which galaxies appear to move away the fastest?
Those that are already farthest from us do.The farther they are from us, no matter in which direction, the faster they're receding from us.The general tendency is that galaxies that are farther from us move away from us faster.
Which statment best describes how galaxies generally move?
Galaxies generally move through space due to the expansion of the universe, which causes them to drift away from each other. This motion is observed as a redshift in light from distant galaxies, indicating they are receding. Additionally, galaxies can interact gravitationally, resulting in mergers or collisions, but the overall trend is that galaxies are moving apart as the universe expands.
Which of these facts is the best supporting evidence that the universe is expandingThe stars vary in chemical composition The galaxies can spin to form eddies. The universe is filled with galaxies of?
The best supporting evidence that the universe is expanding is that galaxies are receding from one another, indicating that the universe is expanding over time. This observation is based on the redshift of galaxies, known as Hubble's Law.
Red shift data sHow is that galaxies are?
We can't be sure. The only thing we know for sure is that it could be explained asthe speed with which that galaxy is receding from us. If that's actually the causeof the red shift, then from all the red shifts that we observe, we have to concludethat all of the distant galaxies are receding from us, and the farther away one isalready, the faster it's receding. If all of that is true, then the whole universe isexpanding. This is the research that made Hubble famous.Well said, but there is another reason. Maybe the light is coming from a large star (gravity hole, red shift due to gravity).
What happens when light from distant galaxies is shifted towards longer wavelength?
When light from distant galaxies is shifted towards longer wavelengths, this phenomenon is known as redshift. It occurs due to the expansion of the universe, causing galaxies to move away from us. As a result, the wavelengths of the emitted light stretch, indicating that these galaxies are receding. Redshift is a key piece of evidence supporting the Big Bang theory and helps astronomers determine the rate of expansion of the universe.
What are the names of three forms of evidence that support the big bang theory?
The main evidence for the Big Bang is the expansion of the Universe, as seen from the Doppler effect. That is, light from other stars or galaxies changes color depending on the relative velocity to Earth; it turns out that all far-away galaxies are receding from us.
What affects the amount of red shift seen in the light from a galaxy?
We can't be sure. The only thing we know for sure is that it could be explained asthe speed with which that galaxy is receding from us. If that's actually the causeof the red shift, then from all the red shifts that we observe, we have to concludethat all of the distant galaxies are receding from us, and the farther away one isalready, the faster it's receding. If all of that is true, then the whole universe isexpanding. This is the research that made Hubble famous.
