Was the Big Bang just a single explosion of a repeatative process? Does the universe expand and contract in rythem, much like that seen within energy waves or atomic organization. Pulling itself into a singularity and exploding over and over again, perhaps forever?

Is it just like one giant perpetual energy machine? If that's possible, wouldn't light given off at the edge of the universe be lost as total energy, causing an eventual breakdown of the system, or is the universe supposed to just expand forever?

If it's possible that it will expand forever, what were the factors that had to already be in existance that caused this reaction? Is it possible that the universe is only one of many within a multiverse?

Perhaps our galaxies and our universe composes the "fundemental" building blocks (the quarks and atoms so to speak) of another level of existance.

Is it possible that if we keep breaking down energy into smaller forms we'll eventuall stumble upon our own existance?

A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off it continues to rotate with a constant angular deceleration for 24.7 s before coming to rest.
(a) If its initial angular speed was 2870 rpm, what is the magnitude of its angular deceleration?
...rev/s2
(b) How many revolutions did the centrifuge complete after being turned off?
...rev

I have some raw hard red wheat that I bought in a bag to turn into flour. Can I just plant these in the ground to grow into wheat or do I need actual wheat seeds to plant?

Also once I plant the wheat do I need to re-plant the crop each year after I harvest it, or do I just let it grow back to harvest again?

Once they grow are the vulnerable to animals such as birds or deer?
