Are we Alone in the Universe?

“It’s impossible for [this] to be the only world…There are other intelligent entities out there, probably since life is so ardent…[do] you think that’s [life] only on this little rocky planet?” – William Shatner

The legendary Captain Kirk said these words after his flight on the Blue Origin NS-18 spaceflight. Is he right? Are the many people who have looked at the heavens and concluded, “There must be more life out there,” correct?

Probably not. What Shatner and others are saying is not a scientific argument. It is barely a viable statistical one. What we may think is true, or wish to be, must always give way to physics.

Life is very complex and requires very specific conditions, controlled tightly by very narrow constraints. We aren’t just talking about the obvious like temperature or air composition. There are a vast number of interconnected systems, large and small, terrestrial and cosmic, that allow us to be here at this time, in this place, on Earth.

For decades, astronomer Hugh Ross has been documenting the constraints that must be met, and cannot change, for life to exist. This is true of primitive life, to say nothing of complex life such as animals or humans. Among the hundreds of parameters he has identified from scientific studies:

  • A planet’s distance from a star, cannot be too far or too close (temperature and gravity).
  • A star’s size, age, luminosity, and type, among other things, must be in the right range for life to exist.
  • Tectonic activity (earthquakes) must not be too great (destructive), or too little (they recycle soil nutrient runoff from rivers).
  • Speed of a planet’s rotation (too fast creates hurricane speed winds, or too slow makes it too hot), its size (too much, or too little gravity), and a precise amount of oxygen (too much causes uncontrollable fires, too little, and large life can’t live), and even the size and distance of any satellites (like the Moon, which affects Earth’s rotation) impact the existence of life.

There are hundreds of such constraints, from the quantum level to the galactic. Even the Big Bang at the origin of time and space, had to be so fine-tuned for Earth to exist here and now as it does. Mathematically, there is zero chance of this occurring on its own from random processes. What does this mean? Two things: One, these constraints eliminate millions and billions of star systems from contention of harboring life. Two, only design can explain what science has discovered.

Naturalists don’t like the implication of design behind the universe’s origin, and call these constraints anthropic coincidences, even though chance cannot explain what we observe. Nonetheless, opponents to design try to sweep this all away with one or another version of the anthropic principle. The popular “weak” version states, “We ought not to be surprised at the order and fine-tuning we see in the universe around us, since if it did not exist…we would not be here to observe the fine-tuning.” This was from Oxford mathematician, John C. Lennox, who further explains why this doesn’t work:

All the anthropic principle says is that for life to exist, certain necessary conditions must be fulfilled. But what it does not tell us is why those necessary conditions are fulfilled, nor how, granted they are fulfilled, life arose.

Evangelists of chance-based, naturalistic explanations like Carl Sagan struggled with this. He marveled at the complexity and beauty of the universe, yet claimed Earth was just a “pale blue dot” and our place among the stars was “demoted” due to the discoveries of Copernicus and Galileo. It didn’t dawn on Sagan and his successors that scientists like Copernicus and Galileo studied the heavens to learn more about Creation and its Creator. Never did they think they were demoting humanity. As astronomer Guillermo Gonzalez has documented, not only have we not been demoted, the evidence points to Earth as being a “privileged planet” that could not be the result of chance, but was created in such a way to make the fine-tuning of the universe evident.

So while we cannot eliminate completely the possibility of life elsewhere among the stars, the physics of the universe guarantees it is exceptionally rare, at the very least. Should we feel despondent and depressed that we could, in fact, be on our own? Not at all. If, as the evidence points, everything from the moment of the Big Bang onward, conspired to allow Earth exist here and now, with its humans, we should feel quite special.

We aren’t a pale blue dot, but rather, we are a bright blue star in the cosmos. Rare and special, with design and purpose.

What does this mean for the current, how should I say, obsession, with UFOs/UAPs? I’ll be returning to this subject in part 2 as we explore what is going on in our skies.

Until then, ponder on what it means for little Earth, perhaps not at the center of the universe, but nonetheless being its central purpose.

Myths Carl Sagan and Neil DeGrasse Tyson Told Me

Scientists enjoy telling stories. They tell stories about, among other things, the quest to understand the universe — stories that sometimes have implications for belief or disbelief in God…

Too, often, these stories are false.

This is how science historian Michael Newton Keas beings his engaging and enlightening book, Unbelievable: 7 Myths About the History and Future of Science and Religion.

Unfortunately, he his right.

What he is referring to is when celebrity scientists stop talking about science and interject their personal beliefs under the guise of science. If those beliefs aren’t friendly to religion, they have a habit of promoting the false religion-is-at-war-with-science narrative with a variety of myths. The war between science and religion  is a modern fable, not surprisingly promoted by those who don’t think highly of religion.

This is a shame, really, because we need popularizes of science, but when some scientists become celebrities, they can fall off their intellectual foundation rather quickly. When Neil DeGrasse Tyson turns Giordano Bruno into a martyr for science in his show Cosmos, much of the story is fiction. When Carl Sagan made claims to the effect that the cosmos is all that there is or always will be, he wasn’t making a scientific statement, but a personal, philosophical one. When Sam Harris claims the church had been “torturing scholars” for “speculating about the nature of the stars,” it simply isn’t true.

It’s not hard to review history, as Dr. Keas shows, and see there is no widespread hatred of science from religion. In fact, he details some of the ways “theistic religion nurtured the development of modern science from its start.” He also reveals the irony of these celebrity thinkers replacing religion with their own naturalistic philosophy and materialistic magic.

I’ve studied a lot of history and science over many years, so I have seen elsewhere the history Keas lays out.  Such as there is far more to the Galileo story — he isn’t the poster child of a war between the church and science. The Dark Ages weren’t so dark — the Renaissance didn’t appear out of nowhere. Nor were most of our ancestors really confused about the shape of our planet — most thought it was a sphere and didn’t need Columbus to prove it (he didn’t think it was flat either).

Do the celebrities purposefully spread their myths? I hope not, but the history isn’t hard to find and they keep repeating their myths anyway.

The takeaway from Keas book is we should learn to recognize when our experts, celebrity or otherwise, switch from teaching to evangelizing. There’s nothing wrong with the latter, unless you are passing it off for something it isn’t. And don’t for a moment think you aren’t capable of testing and questioning those who portend to speak for all of science and history.

They don’t own all the keys to our past and our universe. We all do.

Among the Darkness

In the midst of all these shades of Sun, darkness, existence, and time are those shadows created by radiant light. Here is where the Light will dawn in the face of gathering darkness. As some men love the darkness, others search out the lights shining in the night. There, in the borderlands of existence as most people remain unaware, is where the conflict will play out. – Grayson Kirby, the Tower Keeper, Among the Shadows.

The conflict between Darkness and Light is a central theme in Among the Shadows, and throughout much of fiction. This face-off also exists in the physical world.

Paradoxically, Earth sits in one of the darkest corners of the Milky Way Galaxy, in a universe consisting of 99.73% darkness (dark matter and dark energy). A rare, bright blue orb floating in darkness — not the pale blue dot that the great evangelist of materialistic philosophy Carl Sagan often glumly intoned about.

Interestingly, if the properties of dark energy varied as little as one part in 10 to the 120th power, we would not exist. According to math and logic, chance cannot create such precision no matter how old the universe, nor how many fanciful multiverses one conjures.

Even the vast darkness of the universe is ultimately beholden to a bright blue light. As Darkness and Light battle it out on our world, the universe it sits in shows the war can be won.
