How can you tell the universe is accelerating away from a center and not accelerating toward a center?
A thought experiment: A mile high unlit black box is setting on earth. Three lit rocks are dropped from the top a few seconds apart with a sleeping astronomer (who knows nothing about his situation) on the second rock. Astronomer wakes up sees rocks 1 and 3 accelerating away from him and assumes his universe is expanding.
What else can I help you with?
Is it true that A person on a merry go round is constantly accelerating away from the center?
true:apex
What is the key piece of evidence showing that the expansion of the universe is accelerating?
The key piece of evidence showing that the expansion of the universe is accelerating is the observation of distant supernovae, which revealed that they are moving away from us at an increasing rate. This discovery, made in the late 1990s, provided strong support for the theory of dark energy driving the accelerated expansion of the universe.
What is happening to the universe since the big bang?
Since the Big Bang, the universe has been expanding. Galaxies are moving away from each other as space itself expands. This expansion is happening at an accelerating rate, driven by dark energy.
A person on a merry-go-round is constantly accelerating away from the center.?
False
What is the correct interpretation of a redshift larger than 1 in the context of cosmology?
A redshift larger than 1 in cosmology indicates that the universe is expanding at an accelerating rate. This phenomenon suggests that galaxies are moving away from each other at a faster pace, implying a dynamic and evolving universe.
What planet or star is in the center of the universe?
There is no specific planet or star at the center of the universe. The universe is constantly expanding in all directions from the Big Bang and does not have a central point. Each observer will see the universe as expanding away from them, giving the illusion of a center.
Are all galaxies moving away from ours because your galaxy is at the center of the universe?
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
Are most galaxies moving toward or away from each other?
Most galixies are micing away from each other, at a constantly accelerating pace as time passes.
Is it true that A person on a merry go round is constantly accelerating away from the center?
true:apex
What is the motion away from center or axis?
Motion directly either toward or away from the center is 'radial' motion. Motion where the distance from the center is constant is 'tangential' motion.
What is the force on an object pulling toward then center of a circular path?
Centripetal force is the force toward the center of a circular path. It is often confused with centrifugal force, which is the force away from the center.
Why are you not the center of the universe?
Actually, each of us _is_ the center of our own "observable" universe. And for all we know, we're at the center of the real universe as well. In fact, we can't know if the universe HAS a "center", or where it is; all we can see is that most of the other galaxies seem to be ,moving away from us. So perhaps we ARE at the center? Nah, not likely.

What does the red shift tell us about the changing universe?
Mainly that the Universe is expanding. Analyzing far-away galaxies, it has recently become clear that the expansion is accelerating - the Universe is now expanding faster than a few billion years ago.
How fast are the farthest outer galaxy's traveling from the center of the universe.?
There is no such thing as the "center of the Universe". It is believed that the Universe looks the same from different places, there is no way to determine a "center". The farthest observable galaxies move away from us, at several times the speed of light.
Is universe moving towards us or away from us?
Neither. The definition of the 'universe' is: Everything that exists. And since that includes us, we are inside of the universe. The Universe is, however, thought to b expanding, and expanding faster at its outer edge. So the outer edge of the Univere is moving away from us. We, on the other hand, are moving away from the center of th e Universe (wherever that may be) so we are at the same time getting more distant from the center.
Why cant the center of the Milky Way be seen?
The Milky Way is the center of the visible universe, as the boundary where matter travels away from the observer faster than light is at a constant distance in all directions. The universe beyond this point is unobservable, as the spacetime is moving away faster than light.
