Earth In The Universe

The universe encompasses all matter and energy, having originated approximately 13.7 billion years ago with a monumental event known as the Big Bang. This explosion set in motion the expansion of the universe, a phenomenon evidenced by the red shift observed in the light from distant galaxies, indicating longer wavelengths as they move away.
