What does General Relativity Theory say about time travel?

AI Thread Summary
General Relativity Theory suggests that time travel could be theoretically possible through concepts like wormholes and time dilation, yet practical implementation remains highly debated. Arguments for time travel's possibility often reference the bending of spacetime, while counterarguments highlight paradoxes and the immense energy required. The discussion emphasizes the distinction between theoretical frameworks and real-world applications, noting that while science entertains the idea, practical time travel is not currently feasible. For further exploration, introductory resources like Wikipedia can provide foundational knowledge, though they may lack depth for complex inquiries. Overall, the intersection of General Relativity and time travel remains a captivating yet unresolved topic in physics.

I am going to give write an essay about time travel.
What does science say?
What is the arguments for possibility and against possibility.
And what does General Relativity Theory say about time travel?

Theoretical possible, but not practically?

Wikipedia is usually a good intro reference for simple stuff, but can be problematical for more complicated stuff like your question. Still, it might be good reading for you to get started, and you can follow the links out of the page to other references:
