Is the present moment an illusion, and does it render our choices meaningless?
In short: Science writer Jo Marchant examines the block universe model, which suggests time is fixed and free will is illusory. She explores whether quantum mechanics provides a loophole for human agency, drawing on cosmology, neuroscience, and psychology to question if our perception of 'now' holds any objective reality.
The block universe theory posits that the past, present, and future are all equally fixed, challenging the notion that individuals possess genuine free will. This perspective suggests that the flow of time we experience may not be a fundamental feature of the universe.
However, some physicists argue that this model is incomplete. By investigating quantum mechanics, researchers are looking for evidence that the future remains open, potentially allowing for real choices. This exploration, presented at The Royal Institution on June 22, 2026, connects complex physical theories to the practical implications of how we live our lives.
