ivillage single mom and dating - Carbon dating christian perspective
One problem with earth dating is that the original earth surface is assumed to have eroded long ago.But assuming the earth was formed at the time of the rest of our solar system, then recovered moon rock and meteorites can also be used to estimate the age of the earth.This implies the earth is at least 20 million years old.
The technique gave 90 million years, but took no account of the non-constant erosion rate, or the loss and recycling of salt, or the fact that salt is obtained from other sources as well as continents.
More recently, work has been done on ocean sediments [S. This suggests that, given the current annual rates of erosion (some 27.5 billion tons), all earth's continents would be delivered into the oceans in just 14 million years.
The earth precesses (wobbles like a spinning top) around the sun in a series of cycles.
These cycles affect sunlight and hence long-term can form layers in rock.
Most people accept the current old-earth (OE) age estimate of around 4.6 billion years.
This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution.Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint.A full discussion of the topic must therefore include the current scientific challenge to the OE concept.Absolute dating supplies a numerical date whilst relative dating places events in time-sequence; both are scientifically useful.This is based upon the spontaneous breakdown or decay of atomic nuclei.The time required for half the original number of parent atoms to decay is called the half life.Tags: Adult Dating, affair dating, sex dating
