When this happens gasses dissolved in the magma are able to come out of solution, forming gas bubbles (the cavities) inside it. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles.
He took them to the Argonne National Laboratory, where he was granted time on a late-model mass spectrometer. In a meeting in Wisconsin soon afterward, Patterson revealed the results of his study. The definitive age of the Earth is 4.550 billion years (give or take 70 million years). The current estimate for the age of the earth is 4.54 Â± 0.05 billion years (4.54 Ã 109 years Â± 1%).
We have a problem not only with a six-day creation, but also with the age of the earth. Is the earth a few thousand years old or billions of years old (as scientists today insist)? (p. 121) On a preliminary reading RC Sproul would appear to be non-committal about the age of the earth. Although the Bible clearly says that the world was created in six days, it gives no date for the beginning of the work. It would be a mistake to become embroiled in too much controversy about the date of creation. (p. 121)
