The Universe's Fate: Will Time Eventually Vanish?
Written on
Chapter 1: The Universe's Lifespan
The universe, as we understand it, has existed for over 14 billion years, and many believe it will persist for many more billions. However, emerging theories, particularly those linked to the multiverse concept, suggest that the universe may cease to exist roughly around the time our sun is expected to perish.
What is a Multiverse?
A multiverse, often referred to as a meta-universe, posits the existence of either an infinite or a finite number of universes. To clarify, Earth is part of the solar system, which in turn is a component of our galaxy. Yet, our galaxy is merely one of countless others, each filled with stars and celestial bodies. This vast collection of galaxies and the matter between them is what we term the universe.
The diversity of stars, planets, and the potential for life across this universe is governed by a single principle: the laws of physics. These laws underpin the debated theory of multiple universes, known as the multiverse.
The Big Bang and Universe Expansion
With the inception of the universe during the Big Bang, all existing matter underwent rapid expansion—akin to inflating a balloon. The balloon universe theory suggests that certain regions of this newly formed universe ceased expanding shortly after the Big Bang, while other areas continued to grow. This phenomenon could lead to the formation of isolated, balloon-like universes, where the creation of stars and planets can occur after expansion halts.
This concept supports the idea of overlapping universes, a notion further explained by string theory. In this theory, elementary particles, such as electrons, are depicted as tiny vibrating strings. A significant takeaway from string theory is the existence of not three but eleven dimensions. The additional eight dimensions are theorized to be intricately folded in such a way that they remain imperceptible to us.
The Conclusion of Time
To navigate the complexities surrounding this theory, mathematicians have employed techniques like geometric cutoffs, allowing them to analyze a limited section of the multiverse to compute probabilities for events. With these cutoffs in place, the notion of the end of time transforms into a conceivable occurrence. Numerous physicists argue that eternal inflation is a logical progression of inflation theory, which emerged to resolve issues tied to the initial Big Bang hypothesis.
According to early Big Bang models, matter clusters currently located at opposite ends of the universe are too distant to have ever interacted. Consequently, the early universe should have appeared quite clumpy. Probabilities in a multiverse cannot be calculated without definitive cutoffs that delineate the boundaries of various universes. Based on mathematical calculations of these cutoffs, our universe, which is approximately 13.7 billion years old, is expected to reach its cutoff in about 5 billion years.
