| 单词 | baby universe |
| 释义 | baby universebaby universeA region of space–time that is connected to another region of space–time by a wormhole. It has been postulated that when a massive object in the Universe collapses to a black hole it could go through the singularity at the center of the black hole and create an expanding baby universe in another region of space–time. Inflation could allow such a baby universe to become large very rapidly. It may be the case that the Universe we live in originated in this way. Although the idea of baby universes is highly speculative and requires a theory of quantum gravity before it can be formulated definitively, it has been investigated by a number of theorists. See also multiverse. |
