The universe includes the sum total of everything that exists including all matter and energy, the planets, stars, galaxies, and the contents of intergalactic space. As someone once said, what makes the universe so hard to comprehend is that there is nothing to compare it with. The most widely accepted model for the origin of the universe is the Big Bang. According to this theory, the universe is 13.7 billion years old, was infinitely hot at birth, and has cooled down as it has expanded. Even with technologies that allow different wavelengths of the electromagnetic spectrum to be recorded, only a small fraction of the universe is open to exploration.Conceptual StrandThe cosmos is vast and explored well enough to know its basic structure and operational principles.Guiding QuestionWhat big ideas guide human understanding about the origin and structure of the universe, Earths place in the cosmos, and observable motions and patterns in the sky?
