Why Aliens May Exist Outside Spacetime | Leonard Susskind

When we imagine aliens, we picture them living on distant planets, traveling in spacecraft, and exploring galaxies. But what if we are thinking too small? What if advanced alien civilizations don’t live inside space and time the way we do? In this video, we explore a mind-bending possibility inspired by ideas associated with Leonard Susskind: that alien civilizations may exist outside spacetime, beyond the physical universe we can observe. Modern theoretical physics suggests that spacetime may not be fundamental. Some theories propose that space and time could be emergent — created by deeper structures such as information, quantum entanglement, or holographic principles. Beyond Human Science explores the mysteries of physics, cosmology, and the hidden structure of reality. From black holes and quantum mechanics to spacetime and the origins of the universe, we dive into the ideas that challenge human understanding itself.
