"What the Bleep Do We Know!?" is a 2004 American pseudo-scientific film that explores the nature of reality and the effects that the mind has on it. The film posits a spiritual connection between quantum physics and consciousness, presenting a viewpoint of the physical universe and human life within it, with connections to neuroscience and quantum physics. Some of the ideas discussed in the film include the notion that the universe is best seen as constructed from thoughts and ideas rather than from matter, and that "empty space" is not empty.

The film has been described as "a kind of New Age answer to The Passion of the Christ and other films that adhere to traditional religious teachings". It offers alternative spirituality views characteristic of New Age philosophy, including critiques of the competing claims of stewardship among traditional religions of universally recognized and accepted moral values.

While the film has been criticized for its pseudoscientific claims, it has also been praised for its creativity and visionary approach to exploring complex scientific concepts. The film features interviews with scientists and theologians, and uses visual effects and storytelling to demonstrate the spiritual connection between quantum physics and consciousness.

"What the Bleep Do We Know!?" is available to watch on various streaming platforms, including Amazon Prime Video and Apple TV.
