Is Time Infinite? 

Currently the most commonly accepted response to "how did the universe begin" among science is that 13.8 Billion years ago the Big Bang, a massive super explosion that took the Universe from a single point of infinitely dense matter and energy into what we know it is today, an ever-expanding form spreading the distribution of mass and energy a little farther with every passing second. 

When talking about why anything in the Universe happens I think it always boils down to one word


You are able to break down the ways in which nature works and extrapolate rules or laws that it follows, but you can never get down to a concrete answer on the deepest level, it all goes back to simply being because of "Nature".  

Nature, that is to say, this supermassive force that we put this simple name to, likes things to work in cycles, or at least from the evidence here on earth, an animal dies; another is reborn, the rain falls; a cloud will begin to form elsewhere.

 We can understand all of this with no issue but we assume that the universe has a distinct beginning and a distinct end. Now this is a purely hypothetical discussion because for all intents and purposes, we can't truly know how the universe will end, we can only know predictions that we've gathered during our tiny blip on the timeline of the universe.

I think that the Universe, just like all the forms of nature we have evidence of, works in cycles. The universe starts ( perhaps with the big bang) and sometime later the universe will end ( Perhaps with the Heat death of the Universe or Big Crunch ). Then it will return to its original state and return anew. Let's go into a bit more detail of just what the Big Bang and the heat death of the universe are first.

What happened in the Big Bang? 

The big bang is the prediction that based on the measurements made today, which show the universe to be constantly expanding, that there was a point in time 13.8 Billion years ago where it began. This would have taken the form of an infinitely small, infinitely dense point in space-time with all the matter and energy inside it. Then this point exploded outward in the biggest wave of energy the universe has ever seen. Creating everything we know today in the form of massive tendrils of energy in matter that would form Hydrogen, which would then, form the first stars and then create all the other elements that we know of today and making the planets and galaxies that we now know the universe to be made up of today. Since the big bang according to the second law of Thermodynamics, Entropy has been increasing meaning that the magnitude and dispersion of chaos in the universe is increasing.

What is the heat death of the universe? 

The second law of Thermodynamics states that entropy is always increasing. Entropy has two heavily interconnected meanings, the first is the level of disorder in a system the second can be thought of as a measurement of energy in a system available to do useful work. 

Let's take an example, say you have a deck of cards perfectly ordered, all the spades in order, then clubs, then diamonds, and then hearts. Now you shuffle that deck of cards, increasing the disorder and randomness of the deck. At the same time, you've released small amounts of energy as heat from friction between the cards as well as your hands, decreasing the about of system energy available to do useful work. 

The heat death of the Universe takes this a step further stating that as entropy throughout the universe increases it will, at some point reach some maximum, some point where all of the energy is so dispersed and disordered, that there is no energy left in the universe capable of useful work. The temperature throughout the universe would even out and black holes would slowly die through the release of Hawking radiation.

I disagree

Now that you have the necassery context, heres an explanation of my Theory called the Cyclic Universe

The Cyclic Universe states that the Big Bang wasnt the starting point for everything ever, It was simply a point along an infinitly long timeline. That means that since the big bang exploded and energy came into our universe in the new form of matter, and then this matter came together with gravity, in a high enough pressure to create other elements (the formation of the first stars). 

As entropy increases and energy gets more and more disorderly, matter spreads out in the expansion we know today. But I dont believe that entropy will reach a maximum and nothing more will happen. 

I dont think that how nature works. I think when entropy is at a near maximum, when the stars have dyed out and black holes rule the universe. The black holes will envelop all the dead stars, and then due to gravity, these ultra-massive blackholes each a mass billions of times greater than our sun, will pull each other together towards the center, where the big bang took place in 3-dimensional space time. When the last Black hole envelops the second to last Black hole. This Black hole, which is of greater size than anything our human brain can even begin to comprehend, will collapse in on itself, into a single point of infinitely dense energy and matter. 

Sound familiar? 

This "end" state sounds exactly like the "beginning". This is where the title of Cyclic Universe comes to make sense. I believe that when this black hole containing all the matter and energy of the universe collapses, it restarts the Cycle that is the Universe, giving way to a new "universe" where it will repeat and evolve just as everything else does. If true, this would mean that the universe is one big Cycle, a Cycle on a scale so grand that a species such as Humans likely cant experience more than just a blip of it, ever repeating. 


This would mean that time is infinite and that the universe is repeating itself forever. the ramifications of this are enormous. Time being infinite means that anything and everything that possibly can happen, will happen. Not just once but an infinite amount of times. 

Now this is nothing more than a thought experiment, and I don't know about you but this is a thought experiment that greatly excites me and can constantly make my thoughts entertaining.
