Can humans create new universes?

Creating a new universe is a theoretical possibility, but it remains far beyond our current capabilities.

Sabine Hossenfelder from the Modern Wisdom explains that if our understanding of the early universe is correct, creating a universe might be feasible in the distant future. This would involve creating the conditions for a new universe to form, which would then pinch off from our own universe and evolve independently. However, this concept is purely theoretical and not expected to happen within the next 10,000 years 1.

Sean Carroll, a theoretical physicist, elaborates on the idea of "baby universes" being born from our own universe, suggesting that while new universes might emerge naturally from existing ones, these universes cannot communicate with one another. He mentions the possibility that our universe itself might have originated from a previous one in this manner 2 3.

Avi Loeb discusses the concept that the Big Bang could have originated from a laboratory of an advanced civilization. This theory posits that once we understand the principles of quantum gravity, it might be possible to create a baby universe by manipulating the vacuum in a controlled setting. This idea connects the origins of our universe to the technological advancements of a prior civilization 4 5.

In summary, while creating a new universe is theoretically possible and a subject of scientific speculation, it remains a distant and complex challenge that current technology cannot achieve. The conversations indicate a profound intersection of physics, quantum mechanics, and cosmology, highlighting both the potential and the immense hurdles such an endeavor would entail.
