- Volume of Universe
7 × 10^22
- Number of stars in observable Universe
100 Billion
- Number of Galaxies these stars are organized into
Milky way
- One of the Galaxies, about 80,000 to 100,000 light years in diameter, about 3,000 light years in thickness, and about 250-300 thousand light years in circumference. Composed of 200 to 400 billion stars. As a guide to the relative physical scale of the Milky Way, if the galaxy were reduced to 130 km (80 mi) in diameter, the solar system would be a mere 2 mm (0.08 in) in width.
Solar System
- Consists of the Sun, nine planets and their 158 currently known moons; however, a large number of other objects, including asteroids, meteoroids, planetoids, comets, and interplanetary dust, orbit the Sun as well. Astronomers are debating over the presence of a tenth planet.The star which we call "sun" is 25,000 and 28,000 light years from the galactic center.It Completes one revolution of Milky way every 226 million years.
Earth
- Earth is the third planet in the Solar system. It is the largest of its planetary system's terrestrial planets. Scientific evidence indicates that the Earth was formed around 4.57 billion (4.57×109) years ago and that its single natural satellite, the Moon, was orbiting it shortly thereafter, around 4.533 billion years ago.
Earthlings
- Earth has approximately 6,500,000,000 human inhabitants (February 24, 2006 estimate).Projections indicate that the world's human population will reach seven billion in 2013 and 9.1 billion in 2050. It is estimated that only one eighth of the surface of the Earth is suitable for humans to live on three-quarters is covered by oceans, and half of the land area is desert, high mountains or other unsuitable terrain.
Dilemma
- 99 % of Earthlings think they are significant, that they are the center of the universe, that whether they live or not makes a difference. They fail to notice just how fragile life is, they fail to notice that the odds to have life on this planet are approximately 1 in 10^415. they fail to understand that just one small, utterly insignificant event at a galactic scale, like an astray asteroid, trying to find it's way, can completely knock the daylight off the planet.
Conclusions
- Nothing
- be happy for nothing
- be satisfied for nothing
- be at peace and absorb nothing with all its nothingness.
