Many people who witnessed the great eclipse of 2017 will remember it as a wondrous spectacle. But one amateur astronomer saw the event as an opportunity to reproduce measurements of the celebrated general theory of relativity, which provides the basis for understanding cosmological models of our expanding universe.

Earth’s neighbor Mars has created a lot of discovery-driven headlines lately. In one, scientists found seasonal variation of methane in the atmosphere. In another, 3-billion-year-old sedimentary rocks contained “tough” organic material. In a third, researchers think the planet’s surface hosts valleys that look a lot like stream networks seen here on Earth. But undoubtedly, the evidence indicating the existence of a large, subsurface lake at Mars’s south pole generated the most buzz. Each of these discoveries was hailed as signs that Mars once supported life—or might still today. While the question of whether life ever lived on Mars remains unanswered, all these discoveries ultimately point to the amazing design behind Earth’s capacity to support life.

My family vacationed in the California redwoods and the giant sequoias this past summer. Seeing these majestic trees towering above the surrounding landscape invokes a sense of awe and wonder along with a feeling of smallness. Just to give a perspective on the size of a sequoia, I calculated that one tree has enough wood to make 10 billion toothpicks! I still enjoy visiting the scenic groves of sequoias and redwoods, but I am reminded that for much of Earth’s history, nothing remotely resembling such amazing life could exist.

Back in the summer of 1950, famed physicist Enrico Fermi visited Los Alamos National Laboratory and discussed the possibility of interstellar travel with his colleagues as they walked to have lunch. In the brief exchange, some thought faster-than-light (FTL) travel was possible while others thought not. During lunch Fermi posed his now legendary question: “Where is everybody?” Remarkably, although the question came out of the blue, everyone understood its implications.

“But wait, there’s more!” This infamous phrase preceded the offer of yet another “great” benefit if you bought a Ginsu knife set or a Popeil Pocket Fisherman. Infomercial producers seemed to know that they needed to provide some unexpected bonus for people to watch the whole sales pitch. And this phrase played on our desire to get something more. Not to be outdone, NASA just declared its own “but wait!”

A few weeks ago, I highlighted scientific advances of a “self-aware” cyberslug. Not to be outdone, scientists have now developed materials that automatically make mechanical and electrical repairs to themselves when damaged. Does this mean that replicating life in all its glory is just around the corner?

Perhaps our universe isn’t as finely tuned as we thought! We know that life requires stars and planets to form. Overly rapid expansion of the universe would prevent this from happening and a larger amount of dark energy means that the universe expands more rapidly. Yet a recent paper shows that the amount of dark energy in the universe could be hundreds of times larger and yet still permit stars and planets to form. This result seems to reduce the role of fine-tuning, right? Sort of, but not really. In fact, this discovery makes multiverse explanations for the intricate balances that life requires even more difficult to accept—if you demand a purely naturalistic multiverse.

Davies basically argues that scientists must largely accept that the laws of physics work without having an adequate understanding of why they work. Nothing about the laws of physics specifies that they must appear the way they do or that they should exhibit the regularity, order, and understandability that they do. As you could imagine, the claim that science is founded on faith produced some rather strong reactions—which you can read in a conversation that took place at the Edge. The responses highlighted three important points.

On September 1, 1859, the Sun experienced an unusually large storm that ejected a massive cloud of charged particles. Seventeen hours later, on September 2, the cloud collided with Earth’s atmosphere, generating one of the most spectacular displays of the aurora borealis ever recorded. Even people in Hawaii and Cuba witnessed the aurora! So much electromagnetic energy coursed through the Earth that telegraph operators across the Atlantic Ocean could operate their equipment without connecting it to any batteries. Estimates of damage caused by such an event today range upwards of $2 trillion just for the United States. Yet, these remarkable events highlight another way that Earth seems designed for us to live here.

What do these movies have in common? Bicentennial Man, Tron, Short Circuit, WarGames, Star Trek: The Motion Picture, D.A.R.Y.L. If you guessed that artificial intelligence is crucial to the plot, and that you must be older than 40 to recognize many of them, you would be correct. Maybe a more current list would include Chappie, Transcendence, Avengers: Age of Ultron, Transformers, and Rogue One. If Hollywood movies are any indicator, we find the concept of self-aware creatures fascinating. So the real-life attempt to make a self-aware “cyberslug” should not surprise anyone.

As announced in the Daily Mail, the renowned Stephen Hawking died peacefully at his home on Wednesday. Since I work for an Christian organization that talks about science-faith issues, I thought quite a bit about what I would say if asked about his passing. Given that Hawking did not believe in God, could I give Stephen Hawking a eulogy—a speech that would praise him highly? Yes, I could.

Find the common theme among these things: a good joke, a well-hit baseball, a long touchdown pass, a moving piece of music. Give up? They all rely on precise timing. Each clearly requires accurate execution of a task. However, if that execution happens too early or too late, the joke fails, the ball goes foul, the pass drops incomplete, and you get cacophony. On the other hand, play all the musical instruments together and you get a great symphony. Timing also plays a critical role in Earth’s capacity to support human life.

If we were transported to the late 1800s, we would learn that the prevailing scientific picture of the universe was that it had always existed. Matter and energy moved around in absolute space and eternal time. Since that time, the development of Einstein’s general theory of relativity, the discovery of the expansion of the universe, and the formulation of various space-time theorems (even ones that apply to hypothetical multiverses), strong scientific evidence points to a beginning for the universe. Given that I expect God’s revelation in Scripture and creation to agree, this result is entirely unsurprising—even though unexpected by scientists.

Often, skeptics of Christianity cite the “scientifically inaccurate” description of the creation account in Genesis 1 as a reason to dismiss the Bible. However, in doing so, they neglect to take into account the frame of reference described in the early verses of the chapter. Genesis 1:1 starts with the creation of the entire physical realm (“In the beginning God created the heavens and the Earth“) but then shifts to the surface of the Earth in Genesis 1:2:

Has the development of science lead to the decline of Christianity? Does a belief that the Earth is old require accepting evolution or rejecting the words of the Bible? How should Christians deal with new scientific discoveries that appear to threaten what the Bible says?
