Yes, the universe is generally considered to be part of nature. Nature encompasses all of the natural world, including everything that exists in the physical realm. The universe, with its vast expanse of galaxies, stars, planets, and other celestial objects, is seen as an integral component of the natural order.
Nature typically refers to the entire material and physical universe, including Earth, its ecosystems, and all the entities within it. It encompasses the laws of physics, chemistry, biology, and other scientific disciplines that govern the functioning and evolution of the universe.
From a philosophical standpoint, the universe is often seen as the totality of all that exists, whether observable or not. It includes all the natural phenomena, processes, and structures, from the smallest subatomic particles to the largest cosmic structures.
Therefore, in most contexts, the universe is regarded as part of nature, embodying the fundamental principles and elements that govern the natural world.
