What did the discovery of background radiation distributed evenly throughout the universe provide support for?
either starlight spectra or moving galaxies.
What led Einstein to hypothesize the cosmological constant?
The brief layman's answer: Einstein was troubled because his own theories of relativity did not support the idea of a constant universe, the universe that he preferred to believe existed. His equations showed that a steady state universe would eventually give in to the forces of gravity. He developed the cosmological constant, basically a 'fudge factor', so that his theories could support a steady-state universe. Shortly after, Hubble's redshift observations provided evidence that the universe is expanding, and Einstein called the cosmological constant the worst blunder of his life. Ironically, interest in the cosmological constant is returning, as a possible way of explaining the acceleratingexpansion of the universe.
How does red shift support the theory of the evolution of the universe?
The light spectrum can be viewed as a slinky. When compressed, the light waves change to the blue end of the spectrum. When stretched, the the light changes to the red end of the spectrum. Physicists know that our universe is expanding because galaxies further away change to the red end of the spectrum. This means the galaxies were once closer together in the past than what they are now. This is one of the many pieces of evidence that supports the Big Bang Theory.
Cosmologists expect the universe to?
They expect the Universe to continue expanding. Right now, the evidence is that the expansion is speeding up. They also expect entropy to continue increasing, so in the distant future, there will not be any free energy left to support life, for example. They also expect quite a few other things; the Wikipedia article on the "future of the Universe" can give you some ideas.
Is there more then 1 universe?
That's not a question that can really be answered for sure right now. But being a scientist is about opening your mind up to things that sometimes just don't seem possible. It's always possible, but there is no hard evidence at this time to support the theory that there is more than 1 universe. To the contrary though, there is also no hard evidence that proves there is only 1 universe either.
Is a scientific hypothesis accepted if there is no way to demonstrate that it is wrong?
It is accepted if the data support it.
What should a Manager do to ensure that the changes he is going to initiate will be accepted and implemented by the employees in the organization?
The most important factor in gaining employee acceptance of new policies is that the manager must be enthusiastic about them. They must be supportive of the changes, or it is unlikely that the employees will support them either.
How do the laws of thermodynamics support that the universe came from nothing?
They don't. What they do support is that the Universe must have had a beginning. This is because, according to the Second Law of Thermodynamics, there are irreversible processes in nature - the Universe can't remain the way it is forever.
Why are theories accepted?
if the theory provides support to the main point or provide a link on the research going on then it is accepted
How does mercury help support life on earth?

The scientific explanation that suggests the universe is expanding relies on two main concepts?
The first concept is that of the redshift, which is the observation that light from distant galaxies appears to be shifted towards longer wavelengths. This indicates that these galaxies are moving away from us. The second concept is the cosmic microwave background radiation, which is a faint radiation that is present throughout the universe and is thought to be leftover electromagnetic radiation from the early stages of the universe. Together, these concepts support the idea that the universe is expanding.
Do address changes need notification if paying child support?
Parties in child support cases must notify the appropriate venue of address changes.
Changes are good for person or not?
Changes are good for a person, unless the changes are not good changes... then, changes are bad for a person. If you support bad changes then you would be supporting bad change for a person.
How do planetary systems support the big bang?
They do not, per se. The perpetual expansion of the universe does.
What will happen after this universe is destroyed?
There is no reason to believe that the Universe will be "destroyed" - it will continue expanding, and at some point there won't be enough free energy left to support any type of life, but the Universe itself will continue existing.
