What Is Dark Matter? | Bedtime Astronaut For Sleep
In this soothing episode of Bedtime Astronaut, we embark on a serene exploration of one of the universe's most intriguing enigmas: dark matter. As you settle into a peaceful state, imagine the vast cosmos around you, where stars and galaxies dance in a celestial ballet. While these luminous bodies form the night sky we know, they account for only a small fraction of the universe's total mass. The rest is a mystery, an unseen force that shapes the very structure of the cosmos. Join us as we journey back to the early 20th century, when astronomers first noticed something peculiar in the movement of galaxies. Stars within these galaxies orbited at incredible speeds, defying the gravitational laws known at the time. This led to the concept of dark matter, an invisible entity that, while not emitting light, exerts a gravitational pull binding these galaxies together. Through gentle narration, we explore the profound influence of this mysterious substance, inviting you to ponder the unseen wonders of our universe.
