How old is Earth? Our world's surprising age, explained
Meet single vegans and vegetarians. Before the age of science, most cultures explained the origin of the Earth through their respective creation myths. These were based on religious texts or oral traditions. Early estimates of the age of the Earth were relatively short, often just a few thousand years. In the late 18th century, James Hutton, the father of modern geology, proposed that geological forces acted continuously over extremely long periods of time. In , Irish mathematician and engineer John Perry calculated the age of the Earth as between 2 and 3 million years. His model included a convective mantle and a thin curst, but most scientists ignored his work. Planet Earth Singles | Best Dating Site for Vegans & Vegetarians

How Is the Age of the Earth Determined? The age of the Earth, currently estimated at ± billion years, is primarily determined through radiometric dating of meteorite samples and the oldest-known Earth and lunar rocks. If you look up the age of Earth on science websites and in publications, you'll generally find an estimate of 4. What you may be surprised to discover is the accepted estimate dates back to the s and has remained pretty much the same since then, even though scientific knowledge has progressed so dramatically since then in other areas. So what's up with that? Efforts to figure out the Earth's age go back many centuries. The classical Greek philosopher Aristotle, who thought time had no beginning or end, also believed that Earth was infinitely old. Meanwhile, religious scholars in ancient India, who envisioned a universe that perpetually exploded, expanded, and collapsed only to begin anew, calculated that Earth had existed for 1.

Green Singles Dating. Earth Science, Geology, Physics. Take a look at a globe or a map of the world and you may be impressed by what you see. Towering mountains, deep oceans, vast continents, and sprawling glaciers—they make Earth what it is today. Scientists have calculated the age of our planet to be approximately 4. But how did scientists determine that age? The answer is complicated: It involves everything from observation to complicated mathematics to understanding the elements that make up our planet.
