Everything thing you see,deal with or know has a cycle.
Even us -Humans- have cycles,from the smallest particle in our body to our whole life from birth till death.
But the cycle I'm talking about here is the greatest cycle of them all which is the "Bing Bang - Crunch cycle".
Before that, I want to mention some cycles that are great but not as great as this one,since the latter involves the existence of the Universe itself,how it all began including time and space.
From Top to bottom, the first cycle involves the Sun.
The Sun goes through approximately 11-year cycles that range from peak activity to quiet and back again. We are near the low point of the current cycle. Scientists have tracked the cycles for decades but have been unable to predict when their durations and intensity.
The new model, known as the Predictive Flux-transport Dynamo Model, has simulated the strength of the past eight solar cycles extending back to the early 1900s with 98 percent accuracy.
Using the model, researchers predict that the next solar cycle, known as Cycle 24, will produce sunspots across an area slightly larger than 2.5 percent of the visible surface of the Sun. They also expect that the cycle will begin in late 2007 or early 2008--about six to 12 months later than earlier predictions--and reach its peak in 2012.

The second cycle is the “Great Cycle” of the “Long Count” calendar (Mayan Calendar)equates to 5,125.36 years. This cycle is claimed to be a great year of spiritual transformation or apocalypse. The current Great Cycle is due to be completed on the winter solstice of 2012, December 21. So, it has been interpreted that on this day, the Great Cycle ends, time ends, so the Earth might end as well. Not everyone agrees however some say it is the era of a new age,which I think is the right opinion.
Scientifically, on the 21st of December 2012 the Earth,Sun and the Black hole - that is at the center of our galaxy- will align. What could be the consequences of this alignment ? No one really knows.
Btw, It's now believed that at the center of every galaxy there is a black hole which actually causes the galaxy to spin, but what is stopping the black hole from sucking in the whole galaxy? Or is it already sucking it but due to the unimaginable enormous size of galaxies it takes a heck lot of time to suck it all in?.
White holes are also believed to be there, but instead of sucking everything in even light, it sprays out matter and light. I can't say it's not there, cuz we know that everything was and is created in pairs, the thing and it's anti. Like antimatter, the mirror image of matter and so on.
The Greatest cycle of them all is the one I mentioned as the "Bing Bang - Crunch cycle".
Some scientists talk about something called "The singularity".
Singularity is actually something but nothing. Once the universe was all squeezed into a spot so infinitesimally compact that it has no dimensions at all.
Outside the singularity there is no where!. When the universe expands, it is not expanding or spreading to fill a larger emptiness. The only space that exists is the space that it creates as it goes.
There was no even such thing called Time, this was also created after the Big Bang.
So what was this Singularity and where did it come from?
Scientists who doesn't believe in God ironically admit that singularity can actually be called "nothing".So according to them from nothing our universe begins!.
Some say that this singularity is actually what the previous universe ended up to after collapsing.According to some the Big Bangs are going on and on all the time. That space and time had some other forms altogether before the Big Bang-forms too alien for us to even imagine-and that the Big Bang represents some sort of transition phase, where the universe went from a form we can't understand to one we almost can.
The "Bing Bang - Crunch cycle" theory is supported by the holy book "The Quran". There it is mentioned in a Surah called "Al Anbeya" verse 104 where it says :
"And (remember) the Day when we shall roll up the heavens like a scroll rolled up for Books, as we began the first creation, we shall repeat it, (it is) a Promise binding upon us. Truly, we shall do it."
There are many questions that we can not answer right now, or maybe never. I mean the sun is already burning up, and a star of this size will be burning for about 10 billion years before expanding and cooling to become a red giant,ultimately using up its fuel. Unfortunately, the Sun is already about halfway through its life time so we have about 5 billion years left.That is of course if nothing bad happens like a comet or a meteroite crashes into Earth. Or the burning up process of the sun exhilarates for some reasons.I mean we discover something new everyday.
Here is something that we can never challenge: God.
