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 cosmological model?A hypothetical scenario for the ultimate fate of the universe
2. What is the mechanism of destruction?Accelerating expansion overcomes gravitational and fundamental forces, tearing matter apart
3. How would the Big Rip happen?It would happen if a special kind of dark energy, called phantom energy, makes the universe expand faster and faster until gravity and other forces can’t hold things together.
4. What would happen to galaxies, stars, and planets during a Big Rip?First, big groups of galaxies would split apart, then individual galaxies, stars and planets would fly away, and finally even atoms would break apart into tiny particles.

Dark Energy: A hypothetical form of energy believed to permeate all of space and accelerate the universe's expansion.
Phantom Energy: A theoretical type of dark energy with an equation of state parameter w < -1, leading to runaway expansion.
Equation of State Parameter (w): A ratio describing the pressure to density of a substance, crucial for understanding dark energy's behavior.
Scale Factor: A measure of the relative expansion of the universe over time.
