The Multiverse Hypothesis Explained by Neil deGrasse Tyson
Science Time・2 minutes read
Physicists support the idea of a multiverse with different laws of physics, stemming from quantum fluctuations. The concept challenges traditional realities and encompasses all universes, sparking debates in the physics community regarding its scientific validity.
Insights
- Physicists support the multiverse theory, suggesting that quantum fluctuations in the early universe could create different laws of physics in other universes, challenging the idea of a single universe.
- Erwin Schrodinger's concept of superposition introduces the idea of multiple coexisting histories, disrupting traditional notions of reality and contributing to the discourse on the legitimacy of the multiverse theory in scientific circles.

What is the concept of a multiverse?
The concept of a multiverse refers to the idea that there are multiple universes existing independently of each other. Physicists believe that quantum fluctuations in the early universe could lead to different laws of physics in these alternate universes. This theory challenges the traditional understanding of a single universe and suggests the existence of a vast array of parallel universes.
When was the idea of multiple universes first proposed?
The idea of multiple universes was first proposed by ancient Greek philosophers, particularly Chrysippus in the 3rd century BC. Ancient Greek atomism discussed the concept of infinite parallel worlds arising from the collision of atoms, laying the groundwork for the modern concept of a multiverse.
What is superposition in the context of the multiverse theory?
Superposition, introduced by Erwin Schrodinger, is a concept where multiple histories coexist simultaneously. This challenges the traditional understanding of reality by suggesting that different possibilities can exist at the same time. In the context of the multiverse theory, superposition implies that multiple universes with different physical laws can exist simultaneously.
How are universes in the multiverse theory described?
In the multiverse theory, universes are described as independent entities expanding without knowledge of each other. This is likened to ships at sea with separate horizons, each universe existing in its own space, time, matter, energy, and physical laws. The multiverse theory posits a vast and diverse array of universes beyond our own.
What are some classification schemes for multiverses?
Various classification schemes have been proposed for multiverses, including Max Tegmark's taxonomy of four levels and Brian Greene's discussion of nine types of multiverses. These schemes aim to categorize the different ways in which multiple universes could exist, providing frameworks for understanding the complexity and diversity of the multiverse theory.
