Time Travel: No worry about paradoxes

Click For Summary
The discussion centers on the complexities of time travel and the associated paradoxes, particularly the grandfather paradox. It argues that if time is relative, as suggested by Einstein, time travelers could exist in parallel timelines that do not affect each other, allowing changes in the past without compromising the present or future. The conversation also touches on the conservation of mass and energy, questioning how these principles hold up during time travel. Additionally, the many-worlds interpretation is proposed as a potential solution to avoid paradoxes, suggesting that each time travel event creates a new universe. Overall, the thread explores the theoretical implications of time travel while acknowledging the challenges and limitations of current scientific understanding.

yeah...that would imply the universe was a being or something that had consciousness.
I'll bet that the argument for 'conspiratorial physics' attempts to sidestep the invokation of a consciousness, but I'd like to see them try. I think anyone who purports this theory has not thought it through beyond the 'makes my stomach feel good' phase.
