Mind uploading refers to the theoretical idea of transferring a person’s mental processes from a biological brain to a non-biological system. This concept involves preserving memories, personality traits, consciousness, and cognitive functions in a different physical substrate. It is discussed in neuroscience, computer science, and philosophy as a long-term possibility rather than a current capability. … Read more
Time can be measured precisely using clocks, yet subjective experience of time varies widely. Identical durations may feel long or short depending on context, mental state, and activity. This variation occurs because time perception is not generated by a single sensory system. Instead, it emerges from multiple interacting brain processes that interpret change, attention, memory, … Read more
Can Consciousness Exist Without a Brain Consciousness refers to the capacity for subjective experience, including awareness, perception, thought, and feeling. In humans and other animals, consciousness is consistently associated with activity in nervous systems, particularly the brain. Changes in brain structure or function reliably alter conscious states. This empirical relationship raises the scientific question of … Read more
The Idea of Reality as a Simulation The simulation hypothesis proposes that reality may be an artificial system rather than a fundamental physical substrate. Under this view, space, time, matter, and physical laws emerge from underlying rules implemented at a deeper level. The hypothesis originates from philosophy and theoretical considerations in physics and computation. It … Read more
