How did the universe begin and how will it end?
But if there’s too much stuff, the expansion of the universe will slow down and stop. Then the universe will begin to contract. A contracting universe will shrink smaller and smaller, getting hotter and denser, eventually ending in a fabulously compact inferno, a sort of reverse Big Bang known as the Big Crunch.Click to see…

Furthermore, how long will the universe last? 14 billion years Additionally, what will be the fate of the universe? The universe will slowly cool to absolute zero: a heat death will occur. Life will be unable to exist. The Universe will collapse in on itself: If the mean density exceeds the critical density, then the expansion of the universe will eventually cease, and the universe will begin to contract. Hereof, how did universe begin? Fundamental mysteries According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.8 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size within a tiny fraction of a second.How can the universe be infinite?The early universe could have just been infinitely small. If the universe was infinite the early universe must also be infinite (because the universe can never expand at an infinite rate) and, assuming all of the universe has matter, must have contained an infinite amount of matter.
