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 object classification?A proposed compact object that avoids a singularity and event horizon
2. What is the proposed core composition?Ultra-dense 'nomatter' phase resistant to further gravitational collapse
3. Why does a gravastar have a shell of dark energy?The shell is made of dark energy, which pushes outward with negative pressure, balancing the pull of the dense core.
4. How does a gravastar avoid a singularity?The dark‑energy shell pushes back against gravity, so the core never collapses into an infinite point or an event horizon.

Event Horizon: The boundary around a black hole beyond which nothing, not even light, can escape its gravitational pull.
Equation of State: A thermodynamic relationship describing the pressure, density, and temperature of matter.
Hawking Radiation: Theoretical thermal radiation predicted to be emitted by black holes due to quantum effects near the event horizon.
General Relativity: Einstein's theory describing gravity as the curvature of spacetime caused by mass and energy.
