There are many devout Jews and Christians who believe the universe is old. Unlike Darwinism, the presumption of an old universe has real support from science. Philosophically, something as grand and as powerful as the entire universe would reasonably seem to be eternal. Standard thermodynamics and the Big Bang hypothesis changed all that, and the age of the universe is no longer viewed as eternal. Perhaps God did not want us to believe the Cosmos is all powerful and eternal, but rather transient and passing. Thermodynamics tells us the stars cannot burn forever, and thus thermodynamics has left us evidence that the known cosmos is not eternal… As much as Young Earth Creationists (YECs) hate the Big Bang, the Big Read More ›

How can there be life, much less a Cambrian explosion, if the early Earth was an ice ball. Astrophysics tells us the Earth should be an ice ball, but why isn’t it? Astrophysics tells us that relative to today, the sun radiated 30% less energy in the time of the Early earth and 6% less energy in the late Cambrian (about 500 million years ago). But even as little as 2% less solar energy hitting the Earth could have turned the Earth into an ice ball. Simple energy-balance climate models of the Budyko/Sellers type predict that a small (2–5%) decrease in solar output could result in a runaway glaciation on the Earth. Susceptibility of the early Earth to irreversible glaciation Read More ›

The stolen concept fallacy is a form of self-refutation. From Wikipedia: Stolen Concept – the act of using a concept while ignoring, contradicting or denying the validity of the concepts on which it logically and genetically depends. In an ongoing, multi-thread sub-debate at The Skeptical Zone, I have been making the case that when materialists argue, they necessarily employ stolen concepts, such as those referred to by the following terms and more: “I”, “we”, “prove”, “evidence”, “reason”, “logic”, “determine”, “conclude”, “error”, “fact”, “objective”, “subjective”, etc. Generally agreed upon by many of those at TSZ (although now I suspect we’ll get a barrage of disagreement via DDS), human beings are material computations of physics, meaning that everything a human does, says, Read More ›

The scientific enterprise entails: 1. observation 2. hypothesis 3. testing Consider this passage from the class text of an introductory cosmology class I took once upon a time: galaxies farther than 4300 megaparsecs from us are currently moving away from us at speeds greater than that of light. Cosmological innocents sometimes exclaim, “Gosh! Doesn’t this violate the law that massive objects can’t travel faster than the speed of light?” Actually, it doesn’t. The speed limit that states that massive objects must travel with v < c relative to each other is one of the results of special relativity, and refers to the relative motion of objects within a static space. In the context of general relativity, there is no objection Read More ›

This morning, CH has by implication raised the issue that has been hotly debated recently: getting a cosmos out of “nothing.” I thought it would be helpful to headline my comment: ______________ >>  . . . “Something from nothing” is always problematic. Now, I know I know, here is Ethan Siegel of Science Blogs in partnership with Nat Geog, inadvertently illustrating the problem: It’s often said that you can’t get something from nothing. And while this may be true for most practical applications of your life, it isn’t true for our physical Universe. And I don’t just mean some tiny part of it; I mean all of it. When you take a look at the Universe out there, whether you’re Read More ›

There is currently a discussion going on about Nagel’s new book, Mind and Cosmos between Ed Feser and Jason Rosenhouse. Feser takes Rosenhouse to task pretty well but there’s one thing that I think he overlooks – Rosenhouse actually winds up conceding the entire argument at the end.

This morning, as I opened up my computer, the following Yahoo News headline leaped out: Will Science Someday Rule Out the Possibility of God? By Natalie Wolchover | LiveScience.com Over the past few centuries, science can be said to have gradually chipped away at the traditional grounds for believing in God. Much of what once seemed mysterious — the existence of humanity, the life-bearing perfection of Earth, the workings of the universe — can now be explained by biology, astronomy, physics and other domains of science. Although cosmic mysteries remain, Sean Carroll, a theoretical cosmologist at the California Institute of Technology, says there’s good reason to think science will ultimately arrive at a complete understanding of the universe that leaves Read More ›
