Universe

The universe is everything that exists — space, time, matter, and energy. It began around 13.8 billion years ago and has been expanding ever since. The universe contains billions of galaxies, each with millions or billions of stars and planets. Scientific study of the universe shows its incredible precision, balance, and laws — reflecting a system far beyond human design.

The idea that the universe is expanding was first proposed through Einstein's general theory of relativity and confirmed by astrophysical research. Scientists noticed that light from galaxies shifts toward the red end of the spectrum, which means those galaxies are moving away from each other. This shows that the universe is steadily growing in size.
