Yukteswar giri, the Guru of Paramahamsa Yogananda (Paramahamsa yogananda is the author of “Autobiography of a Yogi) wrote a book on the subject and give below is the quote from wiki:

“According to the book, the motion of the stars moving across the sky (a.k.a.precession) is the observable of the Sun's motion around another star. The quality of human intellect depends on the distance of the Sun and Earth from a certain point in space known as the Grand Center, Magnetic Center or Vishnunabi Vishnu. The closer the Sun is to it, the more subtle energy the Solar System receives, and the greater is the level of human spiritual and overall development. As the Sun moves around its companion star, it brings us closer to or drives us farther away from Vishnunabi, resulting in the rising and falling ages here on Earth.”

Two points interested me:

1. Sun’s motion around another star.
2. Relation between human intellect vs Solar energy and Solar energy vs proximity of Sun to the “Grand Center”

I picked the easier one to begin with J and started digging around the first point.

I directly started at the “Universe” and decided to track back to earth! (Sources are all from wiki)

Universe

The Universe is everything that physically exists. the entirety of space and time, all forms of matter, energy and momentum, and the physical laws and physical constants that govern them. In a well-defined, mathematical sense, the universe can even be said to contain that which does not exist

Then there is “observable universe” which is the part of the Universe which scientists have succeeded to discover.

Scientific experiments have yielded several general facts about the observable universe. The age of the universe is estimated to be 13.7±0.2 billion years. The universe is very large, possibly infinite, being at least 93 billion light years across, and consisting mainly of matter, rather than antimatter.

There are number of galaxies in the universe.

Galaxy

A galaxy is a massive, gravitationally bound system consisting of stars, an interstellar medium of gas and dust, and dark matter.

Typical galaxies range from dwarfs with as few as ten million (10 power 7) stars up to giants with one trillion (10 power 12) stars, all orbiting a common center of mass. Galaxies can also contain many multiple star systems, star clusters, and various interstellar clouds.

There are probably more than one hundred billion (10¹¹) galaxies in the observable universe.

(Do the math! Hundred billion multiplied by one trillion. That is the probable number of starts (Suns) in the “observable” universe. What % of the “whole” universe is observable, we know not! If the “whole” is infinite, which the scientists suspect, where does that leave us!!!! )

Although it is not yet well understood, dark matter appears to account for around 90% of the mass of most galaxies. Observational data suggests that supermassive black holes may exist at the center of many, if not all, galaxies. The Milky Way galaxy, home of Earth and the solar system, appears to harbor at least one such object within its nucleus.

(Look at the number of uncertain terms, in blue!)

So, the name of OUR 'Galaxy' is Milky Way! Let me touch upon the “Black hole” before we reach there.

Black Hole

A black hole is a region of space in which the gravitational field is so powerful that nothing can escape after having fallen past the event horizon (ie the boundary of the Black hole, where the last event can be detected. Beyond that border, no “event” is recorded by scientists so far). The name comes from the fact that even electromagnetic radiation (e.g. light) is unable to escape, rendering the interior invisible. However, black holes can be detected if they interact with matter outside the event horizon, for example by drawing in gas from an orbiting star.

However, the final, correct description of black holes, requiring a theory of quantum gravity, is unknown.

So, what is at the center of a galaxy?

Super massive black holes at the centers of galaxies

According to the American Astronomical Society, every large galaxy has a supermassive black hole at its center. The black hole’s mass is proportional to the mass of the host galaxy, suggesting that the two are linked very closely.

We had just arrived at the Milky way (our galaxy) before we entered the topic of “black hole”, lets pick up that thread.

Milky Way

Although the Milky Way is one of billions of galaxies in the observable universe, the Galaxy has special significance to humanity as it is the home galaxy of the planet Earth.

The disk of the Milky Way galaxy is approximately 100,000 light years in diameter, and about 1,000 light years thick.  It is estimated to contain at least 200 billion, and up to 400 billion, stars

(200-400 billion Suns, moving around a black hole….is “one “galaxy! Can you imagine??????)

It is extremely difficult to define the age at which the Milky Way formed, but the age of the oldest star in the Galaxy yet discovered is estimated to be about 13.2 billion years, nearly as old as the Universe itself. (Logical..isnt it? :o)))

Location of Sun in Milky way

The Sun, and the Solar System, is found in what scientists call the galactic habitable zone

The orbital motion of Sun.

The Apex of the Sun's Way, or the solar apex, is the direction that the Sun travels through space in the Milky Way. The Sun's orbit around the Galaxy is expected to be roughly elliptical.

The orbital speed of the solar system is 220 km/s.

It takes the Solar System about 225–250 million years to complete one orbit (a galactic year).

(Beat that!!! Traveling at speed of 220kms/s takes 225-250 million years to go around the galactic center once!!!! I am already giddy, Can someone tell me how many generations of men that would mean??! ;o)))

Let us have a peek at our neighbors…nope, not neighboring planet, we have not yet arrive there. We are still touring our galaxy, so it is the neighboring galaxy that I am referring to!

(Wait a sec. Earth moving round Sun and Sun moving round a black hole (galactic center) So logically even the Galaxy should be moving ….right?) so whats the velocity of the galaxy?

Velocity of our galaxy?

In the general sense, the absolute velocity of any object through space is not a meaningful question according to Einstein's Special Theory of Relativity, which declares that there is no "preferred" inertial frame of reference in space with which to compare the Galaxy's motion. (Motion must always be specified with respect to another object.)

Many astronomers believe the Milky Way is moving at approximately 600 km per second relative to the observed locations of other nearby galaxies. Most recent estimates range from 130 km/s to 1,000 km/s. The Galaxy is thought to be moving towards the constellation Hydra, and may someday become a close-knit member of the Virgo cluster of galaxies.

See…the whole universe is on the move…! :o) Finally we are at the sun! Long journey buddy!

The Sun

The Sun is the star at the center of the Solar System. It is a medium size star. (Medium..!huh!) The Earth and other matter (including other planets, asteroids, meteoroids, comets and dust) orbit the Sun, which by itself accounts for about 99.8% of the solar system's mass.

 Energy from the Sun, in the form of sunlight, supports almost all life on Earth via photosynthesis, and drives the Earth's climate and weather

As the Sun exists in a plasmatic state and is not solid, it undergoes differential rotation as it spins on its axis (i.e. it rotates faster at the equator than at the poles). The period of this actual rotation is approximately 25 days at the equator and 35 days at the poles. However, due to our constantly changing vantage point from the Earth as it orbits the Sun, the apparent rotation of the Sun at its equator is about 28 days

Read about The Solar Dieties in different cultures (http://en.wikipedia.org/wiki/Solar_deity)

Then comes the Earth (Honey! I am home! :o))

Earth is the third rock from the sun, where we are all sitting and considering ourselves probably the only “intelligent” form of life in the “universe”!!!!

Now, here after, whenever I use the term “universe”, it wouldn’t be a casual utterance!  I would be more humble and utter it with the respect the word deserves!
