The multiverse is a hypothetical group of multiple universes. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.
“A star’s life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star’s mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar. Eventually the temperature reaches 15,000,000 degrees and nuclear fusion occurs in the cloud’s core. The cloud begins to glow brightly, contracts a little, and becomes stable. It is now a main sequence star and will remain in this stage, shining for millions to billions of years to come. This is the stage our Sun is at right now.
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.”
Astronomers use observatories equipped with powerful telescopes that help them magnify the view of dim and distant objects in the universe. Astronomy tools, like the armillary sphere, were used by early astronomers and new tools came about as the study of astronomy evolved. They also use instruments called spectrographs that dissect the light from stars, planets, galaxies, and nebulae, and reveal more details about how they work. Specialized light meters (called photometers) help them measure the varying stellar brightnesses.
Well-equipped observatories are scattered around the planet. They also orbit high above Earth’s surface, with such spacecraft as Hubble Space Telescope providing clear images and data from space. To study distant worlds, planetary scientists send spacecraft on long-term expeditions, Mars landers such as Curiosity, Cassini Saturn mission, and many, many others. Those probes also carry instruments and cameras that provide data about their targets.
Why Study Astronomy?
Looking at the stars and galaxies helps us understand how our universe came into being and how it works. For example, knowledge of the Sun helps explain stars. Studying other stars gives insight into how the Sun works. As we study more distant stars, we learn more about the Milky Way. Mapping our galaxy tells us about its history and what conditions existed that helped our solar system form. Charting other galaxies as far as we can detect teaches lessons about the larger cosmos.There is always something to learn in astronomy. Each object and event tells a tale of cosmic history.
In a very real sense, astronomy gives us a sense of our place in the universe. The late astronomer Carl Sagan put it very succinctly when he stated, “The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.”
Astronomy turns out to be a complex subject and it requires several other scientific disciplines to help solve the mysteries of the cosmos.To do a proper study of astronomy topics, astronomers combine aspects of mathematics, chemistry, geology, biology, and physics.
The science of astronomy is broken into separate sub-disciplines. For example, planetary scientists study worlds (planets, moons, rings, asteroids, and comets) within our own solar system as well as those orbiting distant stars. Solar physicists focus on the Sun and its effects on the solar system. Their work also helps forecast solar activity such as flares, mass ejections, and sunspots.
Astrophysicists apply physics to the studies of stars and galaxies to explain exactly how they work. Radio astronomers use radio telescopes to study the radio frequencies given off by objects and processes in the universe. Ultraviolet, x-ray, gamma-ray, and infrared astronomy reveals the cosmos in other wavelengths of light. Astrometry is the science of measuring distances in space between objects. There are also mathematical astronomers who use numbers, calculations, computers, and statistics to explain what others observe in the cosmos. Finally, cosmologists study the universe as a whole to help explain its origin and evolution across nearly 14 billion years of time.
Our Sun is a star, one of perhaps a trillion stars in the Milky Way Galaxy. The galaxy itself is one of countless galaxies in the universe. Each one contains huge populations of stars. Galaxies themselves are collected together into clusters and superclusters that make up what astronomers call the “large-scale structure of the universe”.
Our own solar system is an active area of study. Early observers noticed that most stars did not appear to move. But, there were objects that seemed to wander against the backdrop of stars. Some moved slowly, others relatively quickly throughout the year. They called these “planetes”, the Greek word for “wanderers”. Today, we simply call them “planets.” There are also asteroids and comets “out there”, which scientists study as well.
Stars and planets aren’t the only thing that populate the galaxy. Giant clouds of gas and dust, called “nebulae” (the Greek plural term for “clouds”) are also out there. These are places where stars are born, or sometimes are simply the remains of stars that have died. Some of the weirdest “dead stars” are actually neutron stars and black holes. Then, there are quasars, and weird “beasts” called magnetars, as well as colliding galaxies, and much more. Beyond our own galaxy (the Milky Way), lie an amazing collection of galaxies ranging from spirals like our own to lenticular-shaped ones, spherical, and even irregular galaxies.

“In the video below, US Apollo Astronaut and 6th man to walk on the moon, Edgar Mitchell, describes his samadhi experience in outer space.
“The presence of divinity became almost palpable, and I knew that life in the universe was not just an accident based on random processes… The knowledge came to me directly.”
Edgar Mitchell later founded the Institute of Noetic Sciences, devoted to the study of consciousness. As the website says, “The essential hypothesis underlying the noetic sciences is simply that consciousness matters.”
The point of this post is to help you realize that when the scientific mind penetrates reality deeply enough, the field of science morphs into the field of spirituality. A traditional scientist is just someone whose understanding of the metaphysical structure of reality is so thin that he hasn’t realized yet that he IS reality! Oh sure, he knows it intellectually, but not deeply enough, not personally enough that it’s flowered into a full-blown spiritual experience.
Flying into outer space helps to put you in touch with your own universal nature. Which is one of the key reasons why human beings are so fascinated with space exploration and space travel: We want to be Cosmic! But the truth is, we already are Cosmic! We’ve always been Cosmic! You don’t need to fly into outer space to realize this because in fact there is no difference between outer space and inner space. The vacuum of outer space is already here, right now, inside your head! You can fly to the edge of the galaxy and all you will ever find is consciousness. But for a mind thoroughly locked in the materialist paradigm it might take something like flying to the moon to realize its folly. A materialist mind needs an epic material revelation of spirit/oneness/consciousness to break through the lock. Something akin to an angel descending down from the clouds with choir music playing.
A traditional scientist is a dabbler in reality. Sure, he knows some formulas and he’s read a lot of books, but it has not dawned on him yet that the nature of reality is pure, radical subjectivity. So he stands too far aloof from his subject matter. He actually believes that the thing he’s studying is separate from himself. He likes to pretend that he is being “objective”. How myopic!”
The ripple effect reflects on the very nature of affecting change
One small stone tossed into a body of water
Causes a ripple effect with a never-ending forward motion
Inspiring yet another circle for those with daring leaps
Cascading metamorphic spreading
Life plays out in ripples, in all we do and say
Coalescing into a reactive contractive game
Manifest your beacon of light cutting through crevices dark
Let your ripples be love, allow love to spark
Can you see the return of the drops collecting into adhesion?
Concentric circles spreading union until the ripple petulance expires into flow
Poetry is a raindrop, conversing with a puddle to initiate a ripple effect
Unaware of the impact of our throwing of pebbles.
Cosmic bass symphony
Strum torus music of spheres
On string lyre of stars.
Divine operation, my mind a revolving centre
Expansion and fuller expression
Snowflakes of celestial energy
Soft thunderous bursts of consciousness
United recognition of divinity within oneself
Initiates planetary evolution
The sanctum within you of boundless, limitless, unconditioned
Capacity to create infinite
Entranced by the frames
Absorbed within the reality of many
Freezing images that are fluid
Arresting the infinite within the finite
Circling the square, squaring the circle
Attached to the illusion of constant
Paralysed by the scorpions sting.
