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 physical state?Regions of spacetime with extreme mass-energy density, leading to intense gravitational fields
2. What is the key theoretical framework?Einstein's theory of general relativity, which accurately describes their gravitational effects
3. Why do neutron stars and black holes have such strong gravity?They have a lot of mass packed into a tiny volume—just a few kilometers across—so their gravity pulls very hard.
4. How do scientists find a neutron star if it is so small?Neutron stars can be seen as pulsars, which spin fast and send out radio waves that sweep across Earth like a lighthouse beam.

Degeneracy Pressure: A quantum mechanical pressure that resists further compression of matter, crucial for neutron stars.
Singularity: A point in spacetime where physical quantities like density become infinite, theorized to exist at the center of a black hole.
Gravitational Waves: Ripples in spacetime caused by accelerating massive objects, such as merging black holes or neutron stars.
