宇宙會擴張到哪裡去？

宇宙的生命始於大爆炸，大約發生在 140 億年前，且宇宙從誕生之後就不斷擴張。但宇宙如何擴張？它會擴張到哪裡去？莎珍賽妮解釋大爆炸相關的既有理論，以及在我們的宇宙之外有什麼（如果有的話）。

The universe has been expanding since the Big Bang nearly fourteen billion years ago, but it is not growing into pre-existing space. Instead, space and time are woven into the universe itself, so 'expansion' means that the fabric of space stretches everywhere at once. Theories like cosmic inflation and string theory suggest our universe could be one of many, each with its own laws and history, but no evidence yet confirms what might exist beyond our cosmic boundaries. Scientists continue to explore these bold ideas, searching for clues in the deepest reaches of physics and astronomy.
