Why do the laws of physics allow time travel but our reality forbids it?
While the fundamental laws of physics suggest that traveling backward in time is identical to moving forward, our daily experience remains locked in a one-way progression. This video investigates the discrepancy between physical symmetry and the inexorable flow of time toward the future.
The core mystery of time lies in the conflict between theoretical physics and observed reality. If the equations governing our universe are time-symmetric, there is no mathematical reason why time should not flow in reverse. Yet, we experience a universe that moves strictly toward the future.
This exploration serves as an introduction to the nature of time, examining why our perception of an 'arrow' of time contradicts the reversible nature of physical laws.
