Can we scientifically prove the multiverse exists, or is it just a philosophical dream?

Quantum Paradoxes: 5 Ways to Test the Multiverse | Maria Violaris · 56:37 · Video: The Royal Institution · Watch at the source

In short: Quantum physicist Maria Violaris explores five experiments designed to test the multiverse theory. From Schrödinger's cat to modern quantum computing, she examines how strange phenomena like entanglement and measurement might offer a path to verifying the existence of multiple realities.

The multiverse is often dismissed as a purely philosophical concept, but Violaris argues that it can be subjected to rigorous scientific testing. By investigating quantum measurement and entanglement, researchers are attempting to move beyond theory into empirical observation. A key milestone in this journey was a 1985 thought experiment, which unexpectedly catalyzed the modern, multi-billion-dollar race to build functional quantum computers.

The presentation also highlights Google's Willow quantum chip as a modern tool for these investigations. Furthermore, Violaris introduces a novel thought experiment that challenges the conventional wisdom that communication between branches of the multiverse is impossible, suggesting that our understanding of these quantum boundaries may be incomplete.
