Earth Still Privileged Planet

Astronomers have found over a thousand extrasolar planets now. How does our solar system compare? Thanks to the Kepler spacecraft, we now have a catalog of 1,235 alien planet candidates after just four months of operation. Of the 408 that have been found in multiple-planet systems, 170 of these containing two to six planets have been pictured in a “Kepler Orrery” posted by the Harvard-Smithsonian Center for Astrophysics. The press release says, “most of those look very different than our solar system”.

Geology Sinks in the Mud

Question: what is the most abundant sedimentary rock in the world?  Follow-up question: what would happen to the science of geology if the consensus theory of how this most abundant sedimentary rock was deposited turns out to be wrong?  Prepare for a paradigm shift: experiments have shown mistakes in long-held assumptions about mudstone formation. Here’s […]

Is Making Planets Child’s Play?

Are star children good at child's play? Like making mudballs, it should be easy to roll up dust into planets.

Lord Kelvin’s Core Values Defended

Myth: Lord Kelvin held back the progress of geology for 100 years by insisting the Earth was younger than geologists and evolutionists believed. Myth debunked here.

How Not to Date a Volcano

Two teams of geologists looked at the same volcano field in Nevada, but came up with vastly different dates.

Paper View:  Cambrian Explosion Damage Control

Like some federal official holding a press conference after a disaster, a Harvard paleontologist has tackled the unenviable job of explaining what Darwin called the most severe challenge that could be levied against his theory: the fossil record. The challenge starts with a bang...

Rethinking the Geological Layers

One of the most formative ideas in Darwin’s intellectual journey was the concept of gradualism, the principle of “small agencies and their cumulative effects.”  This idea became a dominant motif in his philosophy of life.  Describing how the assumption of gradualism permeated his last book (on earthworms) shortly before his death, Janet Browne, in her […]
