The Multiverse is real. Just not in the way you think it is. | Sean Carroll
Big Think・8 minutes read
The multiverse concept, popular in media like Marvel movies and "Rick and Morty," stems from physicists' discussions on multiple universes based on data, not just philosophical ideas. The inflationary theory of cosmology and the many-worlds theory of quantum mechanics explain our universe while predicting the existence of other universes with different conditions and outcomes.
Insights
- Physicist Sean Carroll highlights that the multiverse theory is not a mere philosophical idea but is grounded in observations and data, emphasizing its scientific basis rather than a fictional concept.
- The multiverse concept spans various media forms, from Marvel movies to "Rick and Morty," reflecting a widespread cultural interest in exploring the idea of multiple universes and their implications beyond the scientific realm.

Recent questions
What is the multiverse concept?
The multiverse concept refers to the idea that there are multiple universes existing parallel to our own, each with potentially different physical laws and conditions. This concept has gained popularity in various forms of media and is a topic of discussion among physicists and philosophers.
How do physicists view the multiverse theory?
Physicists view the multiverse theory as a result of observations and data, rather than a mere desire for a multiverse concept. Theoretical physicist Sean Carroll emphasizes that the multiverse theory is not driven by a philosophical idea of all possible worlds but by scientific evidence and theoretical frameworks.
What are the inflationary theory and many-worlds theory?
The inflationary theory of cosmology and the many-worlds theory of quantum mechanics are scientific theories that explain our universe while predicting the existence of other universes. The inflationary theory suggests rapid expansion in the early universe, while the many-worlds theory proposes that all possible outcomes of quantum experiments occur in different universes simultaneously.
How does the cosmological multiverse differ from the Many Worlds interpretation?
The cosmological multiverse involves parts of our universe with radically different conditions, potentially having different laws of physics and particles. In contrast, the Many Worlds interpretation of quantum mechanics suggests that all possible outcomes of a quantum experiment occur in different universes simultaneously, focusing on the quantum realm.
How can contemplating the multiverse be beneficial?
Contemplating the multiverse can be a useful psychological tool, allowing individuals to visualize different possibilities and make better decisions for the future. However, dwelling excessively on past decisions in the context of the multiverse can be detrimental, as it may lead to regret and hinder personal growth.
