The Universe According to Susskind explores the deepest questions about reality, space and time through modern theoretical physics. This channel is dedicated to long-form explanations, calm narration, and ideas that challenge how we understand the universe.

Inspired by the work of theoretical physicist Leonard Susskind, we explore concepts such as the holographic universe, quantum gravity, black holes, and the nature of spacetime — without sensationalism, and without simplifying ideas beyond recognition.

Here, physics is not treated as news or entertainment, but as a way of thinking. Each video is designed to be slow, reflective, and immersive, allowing complex ideas to unfold naturally over time.

If you are curious about how the universe truly works — beyond surface-level explanations — this channel is for you.
