How small can reality go... before it simply stops existing?
In this deep-dive video, we explore the mind-blowing idea of the smallest thing in the universe — a journey that takes us beyond atoms and subatomic particles, deep into the strange world of quantum field theory and Planck length. At this unfathomable scale, space and time begin to blur, giving rise to mysterious entities like virtual particles, quantum foam, and even vibrating strings predicted by string theory dimensions.
Could the fabric of the universe itself be pixelated? Theories like loop quantum gravity and the concept of emergent spacetime suggest that reality might not be continuous at all. We’ll also explore how phenomena like the Casimir effect, quantum tunneling, and quantum coherence offer clues about the structure beneath everything we know. Even the Higgs boson, which gives particles mass, might be part of a much deeper story.
But it doesn’t stop at physics — we’ll touch on how the observer effect, quantum measurement problem, and quantum entanglement challenge our understanding of observation and reality itself. Are we living in a simulated construct, as the simulation hypothesis suggests? Could the answers lie in the cosmic microwave background, the behavior of dark matter particles, or even the vast possibilities of the multiverse theory?
