Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the theoretical basis?Einstein's theories of Special and General Relativity
2. What is the mechanism for future travel?Time dilation at relativistic speeds
3. How could we travel to the future?Special relativity says that if something moves very fast, time for it slows down compared to us. That means a traveler could arrive in the future when they come back.
4. Can we go back to the past?Physics has ideas like wormholes, Tipler cylinders, and cosmic strings that might let someone travel back. But going to the past could create problems, so scientists are still unsure if it’s possible.

Spacetime Curvature: The bending of space and time by mass and energy, as described by General Relativity.
Closed Timelike Curve (CTC): A path in spacetime that returns to its starting point in time.
Novikov Self-Consistency Principle: The idea that events in time travel must be consistent and avoid paradoxes.
Many-Worlds Interpretation: A quantum theory suggesting all possible outcomes of an event occur in separate universes.
