By looking at the stars, as our ancestors did long ago, one can get only a small idea of ​​the size of the universe. A telescope has allowed us to see further and broaden our understanding. Today's research goes even further and significantly increases our knowledge of the universe. In fact, the universe is so big that no one knows exactly how big it is, because light simply can't travel fast enough to illuminate it. Now let's take this, our one infinitely large universe, and multiply it by infinity. We now have the idea of ​​the multiverse, a theory that states that there is a seemingly infinite amount of universes. Life, on the other hand, does not go on forever. The multiverse, a theory composed of numerous contested explanations, and the anthropic principle, which universes must follow to support life, are necessary to better understand our own existence, showing its extreme rarity. The multiverse is, at its simplest, terms, multiple universes. It is a “proposal that there may also be other Big Bangs that may be completely disconnected from our own” (Bernard and Ellis 2.29). If a Big Bang were possible in our universe, then it should be possible for them to occur elsewhere under similar, or perhaps even different, conditions. This idea seems rather simple, however it encompasses a huge amount of theories and explanations, around a theory that is not yet well confirmed. Although the multiverse would seem like a difficult theory to prove, cosmologists actually have some evidence pointing to its existence. According to cosmologists, particularly Tegmark, the question “is not whether there is a multiverse. . . but rather how many levels it has” (1), suggesting that there is enough evidence for, at least in some......half of the document......exists: us. Perhaps it won't be long before our solitude in the universe ends. Works Cited Carr, Bernard and George Ellis. "Universe or multiverse?" Astronomy Geophysics 49.2 (2008): 2.29-2.37.
