We believe that the universe is expanding.The universe is currently expanding, as evidenced by the Hubble Constant, which indicates that the greater distance a star is from an observer, the faster that star is receding away from the observer. This Hubble Constant holds true for all observers, no matter where they might rest in the universe, and the Hubble Constant applies to all stars in all directions of the sky for each observer.
That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.
It doesn't seem so. There is evidence that the expansion is accelerating (the Universe is expanding faster than in the past). The reason for this is still somewhat of a mystery; do an Internet search on "dark energy" for more details.
In 1924, Alexander Friedman noted that the equations of general relativity have only two solutions: an expanding universe or a contracting universe. Independently of that work, in 1927 Georges LeMaitre used those same equations to show that an expanding universe was the only reasonable description of our Universe. His ideas were later described as a "big bang" by those who opposed them.
Two answers from me. 1. There is more room for possibilities. 2. The big bang theory and how it all went from one little speck to the universe. The discovery channel actually had a show on this once.
universe is expanding at an accelerated rate.
The red shifts show the galaxies are under centripetal force and the red shift indicates the centrifugal force. This indicates that the universe is in continuity, the centripetal and centrifugal forces are in balance.

Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.
Jesuit priest Georges LeMaitre was the first to use general relativity to show that an expanding universe was the only reasonable description of our Universe, the first to suggest that an expansion would have observable effects, and the first to propose that our Universe had (his words) "a day with no yesterday."
Many objects observed in the universe show a red shift. It is believed that this red shift is caused by a Doppler effect - that is, that the objects are moving away from us at a significant fraction of the speed of light. If this is true, then it is evidence for an expanding universe.
Sonic Universe is not a show, it is a comic series and it is already out.
