By whose authority? For all our lives, we have been trained to appeal to authority, and that’s not necessarily a bad thing. We learned to trust our teachers and parents, […]
If we want to test the timeline proposed by Young-Earth Creationists (YEC’s), we need not look far back in geological time. Given that the accepted and documented age of the Earth is […]
Corals are among the most valuable indicators of past climate conditions, due to their sensitivity to water depth, temperature, and acidity. We can infer from the age and depth of […]
It’s been more than a decade since An Inconvenient Truth debuted, so you are all well aware that over the past 800,000 years, periodic changes in Earth’s temperature have generally followed those in greenhouse gases […]
In the wake of World War II, American warships were increasingly being cast into new, scientific roles for the sake of physical oceanography. By the late 1950’s, the hastened efforts to develop effective sonar […]
What is the advantage of using Argon-Argon (39Ar/40Ar) dating over the conventional Potassium-Argon (K-Ar) method? How does it work, and is it reliable?
Active vs. Passive Strategies for Combatting YEC If you haven’t read Dana Hunter’s piece in Scientific American on strategies for combatting Young-Earth Creationism (YEC) in the public sphere, then I highly […]
Caves are among nature’s most meticulous record keepers. Every year, infiltrating rain or snowmelt dissolves the bedrock in which the cavern has formed and deposits minerals inside the cave as iconic formations—stalactites, stalagmites, flowstone, […]
Over the past decade, a new generation of paleontologists has been refining its techniques to recover something that should have been lost forever: remnants of soft tissue. The preservation of soft anatomy, such […]
Andrew Snelling overviews 64 years of research on the decay of 87Rb, only to show that we know its decay rate very accurately. Therefore, radiometric dates are likely trustworthy.
