Science of "Lucy" Movie

                                            "Lucy" Movie Science 

A science fiction film called "Lucy" looks at the idea of utilizing the human brain to its maximum potential. The film takes extensive artistic liberties, crosses into speculative and fictitious terrain, and even contains certain scientific concepts. The science in the film is summarized as follows:

  1. 10% Brain Myth: The main idea of "Lucy" is based on the widely held yet false belief that humans only utilize 10% of their brain's potential. The movie makes the claim that the main character, Lucy, develops greater cognitive skills and exceptional talents by accessing and using more of her brain's capacity.

  2. Neuroplasticity:The concept of neuroplasticity—the ability of the brain to reconfigure itself and form new neural connections in response to learning and experience—is mentioned in the movie. It implies that Lucy's enlarged brain makes extensive use of this neuroplasticity.

  3. Time Perception: "Lucy" explores the idea that as Lucy's brain capacity increases, her perception of time becomes altered.

    She develops the capacity to view time in a different way, which is portrayed as having more awareness and the capacity to control time.

  4. Enhanced Physical Abilities: The movie shows Lucy acquiring improved physical skills, such as increased strength, agility, and control over her body, while her cerebral capacity increases. These skills are proven to be the result of her improved cognitive ability rather than being directly related to brain size.

Despite being a commonly believed view, it's crucial to emphasize that scientific evidence does not support the notion that people only employ 10% of their brain. The brain is actually an extremely intricate structure, made up of several networks and regions that each carry out specific tasks.  For daily tasks, humans use a sizable percentage of their brains.

While "Lucy" incorporates some scientific concepts, it also delves into fictional and speculative elements, such as the exaggerated brain capacity and the extraordinary powers Lucy gains. The movie's portrayal of brain science is more aligned with science fiction and cinematic storytelling rather than an accurate reflection of current scientific understanding.
