Understanding the Arrow of Time
39:15 - 43:11 (03:56)
The arrow of time is not a necessary consideration for many physical phenomena. Time may be an emergent phenomenon and it is possible to make a system go backwards in a laboratory setting.

Time Reversal
Summary
In a laboratory setting, it is possible to carefully manipulate an intermediate-sized system to run backward, despite the second law of thermodynamics. However, reversing time for larger, more complex systems (such as an egg that has fallen and broken) is not currently possible.
