  • Summary

    Time reversal symmetry violation in the eletroweak interactions provides evidence for an asymmetry of time itself, given the Representation View.

  • Summary

    In the Representation View, time reversal has direct empirical significance, breaks the symmetry-to-reality inference, and can be violated in a time symmetric spacetime.

Reversing the Arrow of Time

  • The arrow of time refers to the curious asymmetry that distinguishes the future from the past. Reversing the Arrow of Time argues that there is an intimate link between the symmetries of 'time itself' and time reversal symmetry in physical theories, which has wide-ranging implications for both physics and its philosophy. This link helps to clarify how we can learn about the symmetries of our world; how to understand the relationship between symmetries and what is real, and how to overcome pervasive illusions about the direction of time. Roberts explains the significance of time reversal in a way that intertwines physics and philosophy, to establish what the arrow of time means and how we can come to know it. This book is both mathematically and philosophically rigorous yet remains accessible to advanced undergraduates in physics and philosophy of physics. This title is also available as Open Access on Cambridge Core.
