Brane cosmology

Brane cosmology is a scientific theory about how our universe works. It suggests that our universe is made of two different places that are called "branes" - one place is called the "observable universe" and the other is called the "bulk universe". The observable universe is made of all the galaxies, stars, planets, and other matter that we can see in the night sky, while the bulk universe is made of dark matter and other types of energy that we can't see.

The theory says that the two branes are connected, and that's why we can see our universe from one side and dark matter from the other. According to this theory, our universe was created when the branes collided, and that all the matter and energy we can see today was created at this moment.

The idea of brane cosmology is still being studied by scientists and is not accepted as fact yet, but it does offer an interesting explanation for how our universe was created and how everything we can see in it works.
