Physics tells us that we live in a block universe, containing all of the past and all of the future. What does this perspective mean for our understanding of time, events, and free will?
A model of backward causation in which the future affects the past could help unite quantum mechanics and general relativity – and satisfy a challenge thrown down almost a century ago by Arthur Eddington.
Mapping the ancestral history of spacetime in an effort to unite quantum mechanics and general relativity.
A new model argues the forces between particles in the early universe loosed time’s arrow, creating temporal order from chaos.
Can simple equations really describe the complex world we live in?
