What is the biggest thing in the world?

The biggest thing in the world, by far, is the observable universe. It spans approximately 93 billion light-years in diameter. This vastness contains hundreds of billions of galaxies, each housing billions of stars.

Understanding the scale involves comprehending concepts like <a href="https://www.wikiwhat.page/kavramlar/light-year">light year</a>, which is the distance light travels in a year. Studying <a href="https://www.wikiwhat.page/kavramlar/galaxy%20formation">galaxy formation</a> and <a href="https://www.wikiwhat.page/kavramlar/cosmic%20expansion">cosmic expansion</a> is crucial to grasping the size and evolution of the universe. Furthermore, the concept of the <a href="https://www.wikiwhat.page/kavramlar/observable%20universe">observable universe</a> itself defines the limit of what we can see, based on the age of the universe and the speed of light. Beyond this limit, there may be more universe that remains invisible to us.
