Summary:

- The article discusses the theoretical possibility of paradox-free time travel, as proposed by physicist Ben Tippett from the University of British Columbia.
- Tippett has developed a mathematical model that suggests it may be possible to travel through time without creating logical contradictions or paradoxes, challenging the commonly held belief that time travel is inherently self-contradictory.
- The model involves the concept of a "traversable wormhole" that could be used to travel through time, but the author acknowledges that significant technological advancements would be required to make such time travel a practical reality.
