Universe (Real Life)

This is a profile of the *Universe*, where *Earth* resides from *The Real World*.

## Summary

The **Universe** is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. While the spatial size of the entire Universe is unknown, it is possible to measure the observable universe. The Universe is likely around 13.799 ± 0.021 billion years old since the Big Bang.
