🇬🇧🇨🇳 cosmology - 宇宙学 : English Lesson

Meaning of "cosmology" ("宇宙学"), detailed definition, and a short video lesson below.

Cosmology is the science of the whole universe. People who study cosmology try to figure out how the universe began, how it has changed over time, and what it might be like in the future. They think about things like the Big Bang, galaxies, stars, planets, and even invisible stuff like dark matter. Cosmology asks huge questions such as, “How did everything start?” and “How big is space really?” It’s like trying to read the universe’s life story from the light of distant stars.

When I learned about cosmology, I realized I am made of stardust, which sounds cool until you still have to take out the trash.

I tried to use cosmology to prove I needed a bigger bedroom, but Mom said the universe is expanding, not our house.

The cookie crumbs on my shirt formed a tiny galaxy, so obviously I was qualified to talk about cosmology at lunch.

During dinner, Dad tried to explain cosmology, and Mom said, “Start with the part where the peas vanish from your plate.”

Grandpa said when he was a kid, cosmology was just looking up and saying, “Wow, that’s a lot of stars.”

By starlight, a child opened a small book titled cosmology and whispered cosmology. On the table, marbles for planets, a lamp for the sun, and a chalk dot for the first flash of cosmology showed the start. They rolled marbles to show gravity, traced a timeline of cosmology, and gasped together — then hugged, amazed by cosmology.
