Why the universe doesn't actually care about cause and effectAt the most fundamental level of particle physics, cause and effect may not exist at all. This video explores why our daily experience of linear causality is an illusion created b…
Why the universe exists depends on a field you can't seeImagine a fish that has never known a world without water. To the fish, water isn't a substance; it is simply the medium of existence. Humans live in a similar invisible field tha…
Why the universe forbids knowing everything at onceThe Heisenberg Uncertainty Principle is often misunderstood as a limitation of our tools. In reality, it describes a fundamental property of nature.
