In all chaos there is a cosmos in all disorder a secret order


The Cosmos

There is an order to the universe. It is a hidden order, not apparent at first glance. But if you look closely enough, you will see it. It is the order of the cosmos.

The Universe

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 remains unknown, it is possible to measure the size of the observable universe, which is currently estimated to be about 93 billion light-years in diameter. In various multiverse hypotheses, a universe is one of a possibly infinite number of sub-universes.

Galaxies


Galaxies are massive and far-flung collections of stars, gas, and dust. They come in many shapes and sizes. Our Milky Way galaxy is just one of billions of galaxies in the observable universe.

There are three main types of galaxies: elliptical, spiral, and irregular. They are named for their shapes.

Elliptical Galaxies: These galaxies are shaped like a ball or an ellipse. They have very little dust and gas, so they don’t have many new stars. Most of the stars you see in an elliptical galaxy are old stars that are slowly fading away. The Milky Way is a spiral galaxy.

Spiral Galaxies: These galaxies look like a spinning pinwheel. They have a lot of dust and gas, so they have lots of new stars being born all the time. The two ends of a spiral galaxy (where the arms start or end) are called the “bulge” and the “disk.”

Irregular Galaxies: These galaxies don’t have a regular shape, but most of them look sort of like blobs or lines. Some irregular galaxies used to be spiral galaxies, but something happened to them (maybe they collided with another galaxy) and they lost their shape.

Stars

The ancients saw the stars as flickering points of light in the ethereal sphere that rotated around the earth each day. Greek astronomers believed that the stars were embedded in a crystal sphere and moved with it. The geocentric, or earth-centered, model of the universe held sway for more than 2,000 years until Copernicus proposed a heliocentric model in which the planets rotated around the Sun.

The Order

In every aspect of life, there is an underlying order. This is seen in the patterns of seasons, the way animals migrate, and the behavior of cells. Even though there may be disorder on the surface, there is always an order to be found if we look deep enough.

The Solar System

The Solar System is the gravitationally bound system consisting of the Sun and the objects that orbit it, either directly or indirectly.[1][2] Of the objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit indirectly—the moons—two are larger than the smallest planet, Mercury.[3][b]

The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system’s mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than terrestrial planets. The two largest giant planets—Jupiter and Saturn—are gas giants, being composed mainly of hydrogen and helium; Uranus and Neptune are ice giants, being composed mostly of substances with relatively high melting points compared to hydrogen and helium, called volatiles (such as water, ammonia and methane).[4][5] All eight planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.[c]

As all orbit within this plane generally perpendicular to Earth’s Equator,[6] all currently known Solar System objects revolve about an ecliptic pole at one of Earth’s poles.[7][8] As viewed from Earth’s northern hemisphere (or any other vantage point not on or very near the ecliptic),5the solar system appears to rotate counterclockwise around its ecliptic pole. This apparent motion is caused by a combination of three real motions:
-The motionless rotation of Earth about its daily axis; -The counterclockwise (or direct) orbital motion of each planet around Earth; -The west-to-eastdrift (“wobble”) in Earth’s own axial precession (wobble period: 26 millennia).[9][10][11]

The Earth

The Earth is the only planet known to support life. It is a beautiful place with many different ecosystems that are home to a variety of plants and animals. The oceans, land, and atmosphere all work together to create the conditions that make life on Earth possible.

Life

Life can be full of chaos and disorder, but there is always an underlying order. No matter how dark and difficult things might seem, there is always a light of hope to guide you through. Thissecret order is what gives life its meaning and purpose.
