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 theory type?Relativistic physics, encompassing special and general relativity
2. What is the discoverer?Albert Einstein
3. What is special relativity and why is it important?Special relativity says that the laws of physics are the same for all non‑accelerating observers and that light always travels at the same speed, no matter how fast you’re moving. It shows that time and space change depending on how fast you go.
4. How does time change when you travel fast?Time dilation means that a clock on a fast‑moving spaceship ticks slower than a clock on Earth. The faster you go, the more the time slows down.

Spacetime Continuum: A four-dimensional manifold combining three spatial dimensions and one temporal dimension, as described by relativity.
Inertial Frame of Reference: A frame of reference in which a body remains at rest or moves with constant velocity unless acted upon by a force.
Lorentz Transformation: A set of equations that relate the space and time coordinates of an event as measured by two observers moving at a constant velocity relative to each other.
Geodesic: The shortest path between two points on a curved surface or in curved spacetime, representing the path of free-falling objects under gravity.
