Event horizon , in its simplest definition, is a black hole?s surface. It has a radius of influence that can affect the perception of objects in space. Many astronomy books define it as a very dense region. A teaspoon-full of this object will weigh thousands of tons. Therefore, it has an extreme gravitational pull that even light cannot escape.

Speaking of which, the most common term when it comes to space are the galaxies, which is defined as a bound and gravitational system wherein within this galaxy are various stars, planets and other celestial bodies.

Jeans Instability

Jeans instability - Wikipedia

en.wikipedia.org

In stellar physics, the Jeans instability causes the collapse of interstellar gas clouds and subsequent star formation, named after James Jeans. It occurs when the internal gas pressure is not strong enough to prevent gravitational collapse of a region filled with matter.



At first, I thought Jeans Instability meant something like this.

Roaming

An Earth-sized rogue planet is roaming the galaxy without a star

Most of the rogue planets we’ve found floating in space without stars have been huge, but for the first time astronomers have spotted one about as massive as Earth
