The oldest thing in the world is a rock from space called a meteorite! 🌠 It is even older than dinosaurs! These rocks have been flying in space for billions of years before landing on Earth.
Another very old thing is the stars in the sky. They shine so bright and have been there for a very, very long time! ✨
The oldest things in the world are meteorites and zircon crystals found on Earth! 🌍 Meteorites are rocks from space that are about 4.6 billion years old—the same age as our solar system!
Zircon crystals are tiny minerals found in rocks, and some are over 4.4 billion years old! Scientists study them to learn about Earth's early days.
Stars like the Sun are also very old—about 4.6 billion years! ⭐
The oldest known objects in the universe are meteorites and zircon crystals, but even older is the light from the Big Bang—the cosmic microwave background (CMB)! 🌌
Meteorites, like the Allende meteorite, are about 4.6 billion years old, dating back to the formation of our solar system. Zircon crystals from Western Australia are up to 4.4 billion years old, giving clues about Earth's early crust.
The CMB is the leftover radiation from the Big Bang, about 13.8 billion years old—the oldest 'thing' we can observe! Scientists study it to understand the universe's birth.
