A recent study has revealed that a powerful cosmic event resulted in the expulsion of stars and planets from a galaxy. This phenomenon, known as the "strong force," occurred when a huge explosion within the galaxy caused a rapid acceleration, hurling celestial bodies into space. The study provides insight into the mechanisms that shape galaxies and the formation of stars and planets.

In addition to this discovery, there are several other intriguing cosmic facts that may aid in achieving a restful sleep. Firstly, the concept of "Stelliferous Era" suggests that our current epoch is filled with an abundance of stars, providing a reassuring ambiance.

Furthermore, the discovery of exoplanets, planets beyond our solar system, has expanded our understanding of the vastness of the universe. The existence of these distant worlds can spark one's imagination and evoke a sense of wonder before bedtime.

Additionally, the notion of cosmic inflation, proposed by scientists, suggests that the universe experienced a rapid expansion during its early stages. This concept may elicit feelings of calm and tranquility, knowing that the universe itself has undergone such immense changes and transformations.

Other intriguing facts include the existence of black holes, which are regions of space where gravity is so strong that nothing, not even light, can escape. The concept of dark matter, an elusive substance that outweighs regular matter, inspires curiosity and contemplation. Lastly, the idea of cosmic rays, high-energy particles originating from various sources in the universe, adds an element of mystery and excitement to the cosmic realm.

By exploring these cosmic facts, one may find solace and wonder in the grandeur of the universe, facilitating a peaceful and restful sleep.
