For nearly 4 billion years, plate tectonics has played a critical role in helping Earth maintain its liquid water. Consequently, any search for a genuinely habitable exoplanet should investigate what … more

As we continue to watch and pray and grieve over the developments in Japan, we may anticipate hearing people ask why God permits such catastrophes as earthquakes and tsunamis. Yet without plate … more

Stanford University geophysicist Norman Sleep has outlined some new constraints on habitable planets.1 He explains how the possible existence of advanced life crucially depends upon a planet … more

In the December 2007 issue of Astrobiology Stanford University geophysicists Norman H. Sleep and Mark D. Zoback note that the higher tectonic activity during Earth’s early history could have … more

A team of American astronomers recently announced the discovery of the first known planet outside our solar system to spend its entire orbit within the “habitable zone.”1When astronomers … more

The breakthrough yields yet more evidence for the divine inspiration of the Bible’s words and message. First, let me offer some personal background for this discovery.

I signed my name in the … more

My family lives in one of the fastest-rising neighborhoods in the nation—not economically, but topographically. Our home rises by an average of 9 millimeters (1/3 inch) per year. Sometimes the … more

Uranium and thorium play a vital role in the plate tectonics and volcanism of planets. Consequently, the amount of these two metallic elements influences the ability of any planet to support advanced … more

Researchers have discovered still more indicators of divine design in Earth’s fine-tuned geophysical processes. These indicators belong to an intricate, life-essential cycle (called the … more

Geophysicists have known for years that the energy moving Earth’s crust pieces toward and away from one another (plate tectonics) comes from the flow of heat from the core up toward the surface. … more
