1. There are more galaxies in the universe than stars in the Milky Way
The Milky Way has approximately 200 billion stars, but there are over 2 trillion galaxies in the observable universe. Amazing!
2. The universe is 13.8 billion years old
Recent studies suggest that the universe was created with the Big Bang around 13.8 billion years ago.
3. Space is mostly empty
Despite its vast size, space is mostly empty. In fact, between any two large objects—such as galaxies—there is usually an average of one atom in every cubic meter of space.
4. The universe is expanding
The universe is constantly expanding and will continue to do so until its ultimate demise.
5. Most of the universe is invisible
Invisible dark energy and dark matter make up most of the universe. We can only detect their presence indirectly through their gravitational influence on galaxies and other observable objects.
6. There could be more than one universe
Some theories suggest that there are multiple universes with their own unique physical laws.
7. Time passes at different speeds in different parts of the universe
Time passes differently depending on where you are in the universe. This phenomenon, known as time dilation, occurs because space-time itself is warped near massive objects.
8. Each star has its own story
Every star in the sky has its own unique story and history, making them fascinating objects to learn about.
9. It contains billions of galaxies
The universe contains billions of galaxies, each with their own unique shapes, colors, and characteristics.
10. We can never see the entire universe
Because of the sheer size and age of the universe, we can never observe more than a small fraction of it. There’s just too much for our telescopes to observe!
