Did the universe arise from nothing, or from something?

In 1967, a physicist made a deeply disturbing discovery. By writing the equations of the Big Bang on a blackboard and mathematically reversing time, he pushed the universe back to time zero. The equations gave a shocking result: the volume of the universe becomes zero, the density becomes infinite, and the temperature becomes infinite. In physics, this point is called a singularity — the place where all known physical laws completely break down. But the real question is far more unsettling: What existed before the Big Bang? Was the universe truly born from nothing? Or does “nothing” not actually exist at all? In this video, we journey to the very edge of modern science. From quantum mechanics, which tells us that even empty space is constantly boiling with activity, to the Casimir effect, an experimentally verified proof that the vacuum is not truly empty. From the radical idea that the total energy of the universe may be exactly zero, to cosmic inflation, which explains how the universe expanded from a quantum fluctuation to a size 93 billion light-years across in a fraction of a second. And the implications go even further: eternal inflation, parallel universes, the multiverse, cyclic cosmology, and the Big Bounce. What if the Big Bang was not the beginning, but merely a transition? In 2024, new theoretical work suggests that the Big Bang singularity may be an illusion. Space-time itself may have existed before the Big Bang, and dark matter could be older than the universe we observe today. With the James Webb Space Telescope, cosmic microwave background data, and the search for primordial gravitational waves, physicists are closer than ever to answering humanity’s oldest question. Perhaps our universe is just a bubble born from quantum fluctuations. Perhaps your observation, at this very moment, is what makes the universe real. If you have ever asked yourself: “Why is there something rather than nothing?” then this video is for you.
