The Things You Ought To Know Web site has published a neat video lecture about the Multiverse theory and why it really doesn’t solve the time travel paradox.
The time travel paradox stipulates that you cannot travel back in time because if you do you risk altering events that led to your ability to travel back in time. Some people try to show that an existence can loop back upon itself in some way that doesn’t alter the time traveler’s destiny (to travel back in time).
It’s all very confusing, a lot of fun, and this has all happened before — or not. Maybe it’s happening elsewhere — or not. You won’t know much of anything for sure after watching this video except that you will have seen the video — maybe.
