By looking at the stars, as our long-ago ancestors did, we can only get a small idea of ​​the size of the universe. A telescope has allowed us to see further and broaden our understanding. Current research goes even further and considerably 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. Now you 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 come so endlessly. The multiverse, a theory composed of several contested explanations, and the anthropic principle that the universes must follow to support life, are necessary to better understand our own existence, by showing its extreme rarity. terms, multiple universes. This is a “proposal that there may also be other Big Bangs that may be completely disconnected from ours” (Bernard and Ellis 2.29). If a Big Bang were possible in our own universe, then it should be possible for it to occur elsewhere under similar, or perhaps different, conditions. This idea seems rather simple, but it encompasses a huge amount of theories and explanations, around a theory that is not yet well confirmed. Although the multiverse seems like a difficult theory to prove, cosmologists actually have evidence indicating 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 present for, at least somehow...... middle of paper ...... 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.
