me - from outside

Ah!

This universe - 100 percent; of which 96 percent is invisible(not only to the eye but to the current scientific eye :)), now the remaining is 4 percent, of which 3.6 percent is galactic gas, i.e gasssssss......, only the remaining 0.4 percent make the actual galaxies, stars, planets etc. Now these stars in groups, groups known as galaxies- may be there are individual stars!!- are.... how many??? umm, about 240 to 250 billion; a billion is 1 followed by 9 zeros so there are 240000000000 galaxies in this 0.4 percent of the total, i.e our universe, (I will let alone, the possibility of other universes). Coming to our universe, coming to galaxies, each galaxy would have roughly say about 100 billion stars, so the total stars are.........dont start multiplying :). let me come to our galaxy, the milky way. Its an average galaxy with about 400 billion stars. our star is, as you know... SUN, one of these 400 billion, is about 30,000 light years from the center of milky way; a light year? its the amount of distance light travels in one year, it actually travels 300,000 km (7 times around our planet) in 1(ONE) second, you may do the math for distance in one year! Next...our Sun, runs its own system, solar system, the system revolving around it, with 8(more so) planets, menny asteroids, commets, planetoids... and the Earth our planet is one of those eight, at a distance of 8 1/2 light minutes from the Sun. get the picture!! no... if an ant, hypothetically, sneezes at center of a football field, its sneeze cloud would be a star system, and the next star would be out side the foot ball field ;)
Coming back to Earth....out of the 100 percent of Earth, 70 percent is water, rest is land ; out of it, only 1/4th of land is arable, 12 million square miles out of 57 million square miles of land ; the human population -- the thinking/intelligent (over -thinking/intelligent) species population is close to 7 billion, and I .... am 1.....one creature out of the seven billion along with the other umpteen number of species having countless creatures-- contending for food, water, space-existence.
