The Emergent Nature of Time in Many Worlds
1:11:01 - 1:16:46 (05:44)
The concept of time in the many worlds interpretation of quantum mechanics differs from the traditional notion of time as a fundamental aspect of reality. It is possible, however, to observe the past state of the universe without actually traveling back in time.

Does the universe have a memory of itself?
1:11:01 - 1:13:39 (02:38)
Summary
Does the universe have a memory of itself? While time travel is not possible, the fundamental laws of physics - in many worlds, quantum mechanics or Newtonian physics - conserve information.

The arrow of time is not built into the laws of physics, but rather the universe has special initial conditions that make it appear to have an arrow of time.
1:13:39 - 1:15:04 (01:24)
Summary
The arrow of time is not built into the laws of physics, but rather the universe has special initial conditions that make it appear to have an arrow of time. Additionally, while space and time are not necessarily emergent, certain aspects of them, such as the arrow of time, may be emergent properties.
