By our perspective, our
planet is a wonderfully varied planet. From the frigid
antarctic regions to the blistering
heat of the
Death Valley in California, from the expanding dryness of the Sahara Desert to the rainforests of South America, the world is an amazingly diverse place...
to us.Sometimes it's a good idea to look at something from ANOTHER perspective.
The Earth is approximately 7,925 miles in diameter, this converts to 41,844,000 feet. If one were to compress the Earth to the size of a USGA approved golf ball (about 1.7 inches), this would be a reduction in size of about 295,369,412 times, or about 3.39e-9 (.00000000339%) of the original size. The hightest point on Earth is 29,035 feet above sea level at the top of Mount Everest. The lowest point on Earth is the bottom of the Mariana Trench at 36,200 feet below sea level. The difference between the two is 65,235 feet. Reduced 295,369,412 times, the difference becomes .00022 feet, or .00264 inches. This displacement is far smaller than any human could discern by tactile sensation. The sphere would seem to be perfectly smooth.
According to the law of conservation of matter, the Earth compressed would weigh the same amount as the Earth at full size - 5.972e24kg. According to Newton's Gravitational Constant - F=G M1 M2/r2 - Where G is 6.672e-11N m2 kg-2 and r is the displacement between the center of gravities of the two objects, a person weighing 75kg standing 1.75m tall would weigh in the neighborhood of 491,915,851,851,850 kg or about 1,082,214,874,074,070 lbs. The density of the Earth would be about 5,107,367,321,763,218,431,424,960 lbs/inch3.
One final impressive impact would be with regard to the heat inside the Earth as considered with the law of the conservation of energy in mind. Temperatures in the core of the Earth reach as high as 7500K. Kelvin (K) is Celsius -273.15. Multiply this by 295,369,412 times and one sees that the interior temperature in the core of Earth could reach temperatures as high as 2,215,270,590,273.15 C.
An interesting perspective of our world, I would say.
