David Eagleman - Is Time Real?
Closer To Truth・9 minutes read
Physicists and philosophers question the existence of time, suggesting it may be a construct of the brain and not a fundamental aspect of reality. Neuroscience shows how the brain actively constructs time, influencing how we perceive the world and experience reality.
Insights
- Time, as understood by physicists and philosophers, might not be an inherent feature of reality but rather a construct emerging from deeper principles, challenging traditional notions of its existence.
- Neuroscience research indicates that the brain actively constructs our perception of time, akin to how it processes color, suggesting that our experience of time is a subjective psychological filter influenced by sensory inputs and internal expectations.

"Time: Construct of Brain or Fundamental Reality?"
- Time is a fundamental aspect that physicists and philosophers are now questioning, suggesting it may not be real but rather an emergence from something more fundamental.
- Neuroscience reveals that the brain actively constructs time, as demonstrated by experiments that manipulate individuals' perception of time duration, sequence, and rate of events.
- Newton's linear concept of time is challenged by Einstein's theory of relativity, but Neuroscience introduces the idea of neural relativity, suggesting time may be a construct of the brain.
- The brain's construction of time parallels its construction of color, indicating that time perception may be a psychological filter shaping how we experience the world.
- Physicists and philosophers categorize time into three dimensions: the now, the flow of time, and the arrow of time, with Neuroscience shedding light on the brain's challenge of integrating information from different senses to create a coherent conscious experience.
- The brain's processing of sensory information, influenced by internal expectations and predictions, impacts the perception of time, with signals from different body parts reaching the brain at varying speeds, potentially affecting the individual's sense of time and reality.
