As the universe started its creation with a big bang nearly about 13.7 billion years ago. The universe consists of trillions of galaxies receding from each other with the expansion of the universe. From the study of general relativity, the universe must have an end. The two possiblities of end depend upon the density of the universe. If the density of the energy and matter is less than a certain value called critical density the universe after expanding for some time will come to contract its initial state. The end is called big crunch and the universe is closed. But if the density of the universe will be greater than the critical density, the universe will be expanding forever untill its temperature comes to freeze. This end is known as big chill and the universe is open. General relativity fails to explain the ultimate end of the universe.
Today's mordern theory is the Mtheory and i think the only reason to know the end of this universe is known first how universe was created. According to concept of Mtheory. The universe came to existance with the collusion of two multidimensional branes (branes are the multidimensional planes). There energy of collusion created the matter and energy of this universe. Understanding this very sensitivily, when the two branes collide with each other it is obvious that after the collusion the branes move apart from each other and allowed this universe to expand freely without any disturbance of their density. Presently, the universe is expanding due to the spreading of the two branes from each other and minimizing the effect of their density on this universe. The decreasing effect of the density of two branes increases the expansion energy of this universe. Physicist called this dark energy. The reason of increasing dark energy is due to spreading of branes from eachother. Now when the two branes can come back again for collusion as it was at the time of big bang when they will come towards each other the effect of their density on this universe as a bubble will slow down its expansion and will make it to contract. The space of this universe will contract with all matter and energy and thus finally when the branes will again collide the universe contracts to zero volume and thats singularity. Thus this makes the universe cyclic. I hope this makes us to understand the ultimate demise of this universe through the study of this new modal from Mtheory. Thankyou!

The ultimate demise of the universe
you may remember that the modal of Mtheory was put forth 10 years ago. which showed that how big bang created the universe by space and energy. But my modal describes that how the universe will come to an end in spite of Mtheory modal. This was only a theoretical discussion but soon i will be giving also the mathematical to see the results more clearly.

With the small amount of information you provided nothing you said (except for stuff that was incorrect) hasn't already been modeled. There are lots of similar models for example The Steinhardt–Turok model. You need to provide far more information to distinguish this uniquely. This wasn't a discussion, it was a summary statement on your part. So when you say you'll be providing us with the mathematics 'of your model' you must be claiming to have made advancements in the mathematical framework of mtheory? Again provide proof of this please. Are you saying you have any type of meaningful understanding of colliding branes? Excuse me for my skepticism. Also, if you are indeed talking about something you are personally responsible for the development of and not just talking about well/long/widely established hypothesis this section of the forum to my knowledge doesn't allow for individual user's own theories/models/hypothesis. There used to be a subforum for that, although I don't think it is around anymore so not too sure on the current rule regarding that.
