Question

directions: go to schoology and open up the big bang folder. use nasa’s website to learn about the big bang. fill out the missing blanks below after reading the article. question: what is the big bang? the big bang is how astronomers explain the way the universe began. it is the idea that the universe began as just a single singularity then exploded and stretched to grow as large is it is right now—and it is still expanding some more information just two years later, an astronomer named edwin hubble noticed that other galaxies were moving away from us. and that’s not all. the farthest galaxies were moving faster than the ones close to us. this meant that the universe was still expanding just like lemaitre thought. if things were moving apart, it meant that long ago, everything had been closer together. a tiny, hot beginning when the universe began, it was just _, tiny particles mixed with light and energy. it was nothing like what we see now. as everything expanded and took up more space, it _ down. the tiny particles grouped _. they formed atoms. then those atoms grouped together. over lots of time, atoms came together to form _ and _. the first stars created bigger atoms and groups of atoms. that led to more _. at the same time, galaxies were crashing and grouping together. as new stars were being born and dying, then things like asteroids, comets, planets, and _ formed!

Explanation:

The Big - Bang theory posits the universe began from a singularity, exploded, and has been expanding since. Initially, it was a hot, dense mixture of tiny particles, light, and energy. As it expanded, it cooled. Particles grouped to form atoms, which then combined to make molecules and larger structures. Stars formed and created heavier atoms, and over time, celestial bodies like asteroids, comets, planets, and others formed.

Answer:

When the universe began, it was just hot, dense, tiny particles mixed with light and energy. It was nothing like what we see now. As everything expanded and took up more space, it cooled down.
The tiny particles grouped together. They formed atoms. Then those atoms grouped together. Over lots of time, atoms came together to form molecules and larger structures.
The first stars created bigger atoms and groups of atoms. That led to more complex structures. At the same time, galaxies were crashing and grouping together. As new stars were being born and dying, then things like asteroids, comets, planets, and moons formed!
