30 Theories About the Universes First Particles - The Search for the First Building Blocks

What really happened at the very beginning of everything? We break down 30 theories about the universe's first particles, from the moment of the Big Bang to ideas that challenge reality itself.

From the well-established to the wildly speculative, this video explores the leading scientific and philosophical ideas about the fundamental building blocks of existence. We'll journey through the first moments after the Big Bang to understand how everything we see may have come from nothing.
