FROM NON-BEING TO BEING The Big Bang theory states that the universe began from the explosion of a single point of zero volume and infinite density some 14 billion years ago. Our Sun was created within the Universe (inside our Milky Way Galaxy) about 4 billion years ago. The energy of the "Big Bang," sent everything moving from one center point, outwards in all directions.
The size of the visible Universe is now generally calculated to be 20 billion LIGHT YEARS across. Universe We sit near the center of it. (the speed of light is 186,000 miles per second) The number of Galaxies traveling throughout the known Universe can be summarized as such: There are 60 Galaxies in existence for every person on earth right now.
How long is 1 Billion Light year ? Earth Circumference = 25,000 miles Light can travel around the earth = 8 times in one second! Light travels in…. 1 second = 186,000 miles 1 minute = 11,160,000 miles 1 hour = 669,600,000 miles 1 day = 16,070,400,000 miles 1 month = 482,112,000,000 miles 1 light year = 5,865,696,000,000 miles 1 million light yr = 5,865,696,000,000,000,000 miles 1 billion light yr = 5,865,696,000,000,000,000,000 miles
This is the accurate view of what our Universe looks like from OUTSIDE the UNIVERSE!
Stars come into existence through the compression of the masses of gases and dust in space called "nebulae". Stars give off heat, light and energy. Surprisingly the Sun is not a major star as we believe to be. THE FORMATION OF STARS TAKES BILLION OF YEARS DEPENDING ON HOW MUCH MATERIAL IT CONTAINS AND ITS MASS. STARS
Galaxies are composed of billions of stars. Stars are big celestial bodies such as the Sun. There are about three trillion stars in the biggest galaxy. In a galaxy of an average size, there are about 200 to 300 billion stars, while there are about 100 billion stars in a small galaxy. The galaxy has arms made up of stars, gas and dust clouds. These arms spin around the galactic center at a speed of 330 miles per second (speed of sound).
THE MILKY WAY The Milky Way is the name of the galaxy in which our Earth is located. The Milky Way has the shape of a spiral; in fact, the shape of the galaxy is identical to a "pinwheel". Our Solar System is located a little more than one half of the way out from the center of this spiral- shaped galaxy.
OUR SOLAR SYSTEM In our Solar System, there are nine major planets with 61 satellites and countless asteroids, all revolving around a single star called the "Sun". The Sun is located at the heart of the Solar System.
