The Universe is Stretching!

The universe is everything that exists: stars, planets, galaxies, and even the empty space in between. For a long time, scientists thought it was just getting bigger, like a loaf of bread baking in the oven. But guess what? It's actually stretching out faster and faster, like a rubber band being pulled super hard!

Scientists are like detectives, always looking for clues about space. About 25 years ago, they looked at faraway exploding stars called supernovae. These stars are like cosmic lighthouses, helping us measure distances. By studying them, scientists discovered that the universe's stretching is speeding up!

This stretching is a super big deal! It tells us that something mysterious is pushing the universe apart. It's like finding out there's a secret engine making the universe zoom faster. Understanding this helps us learn about what the universe is made of and where it's going.

Scientists call this mysterious push 'dark energy.' We can't see it or touch it, but we know it's there because of how the universe is stretching. It's like an invisible force making everything move away from everything else, faster and faster!
