There is something in the human person that has never been fully at home here.
Not in the anxious, escapist sense, not the dissociation of someone fleeing their life, but something older and stranger. A constitutional restlessness that seems woven into the fabric of what we are. Augustine called it the heart that finds no rest until it rests in God. The desert fathers called it penthos, a holy ache. The physicists and the tech visionaries are calling it something different now. They are calling it the stars.
The question underneath all the orbital launch schedules and humanoid robots and longevity research is the same question it has always been: what kind of creature are we, and what are we for?
The Vision
The case being made by the people building this future is genuinely staggering. Within thirty years, they believe, humanoid robots will outnumber humans on Earth by a factor of ten. AI will have solved most human disease. The cost of surgery will approach the cost of electricity. As Peter Diamandis recently put it, “all of the things I would get to someday — someday is right now.”
The centerpiece of this acceleration is space. Orbital data centers. Rotating colonies — vast cylinders spinning in the dark, simulating Earth gravity, housing thousands of people at a time. A permanent, irreversible expansion of human civilization beyond the planet. Elon Musk has predicted ten billion humanoid robots on Earth by 2040. Demis Hassabis of DeepMind has said publicly that he believes we will cure all disease within the next ten years. The promise of longevity escape velocity — the point at which science extends your life faster than you age — may arrive in this decade.
There is beauty in this. I want to say that plainly, because the reflexive Christian response to techno-optimism is usually suspicion, and sometimes that suspicion is earned, but not always. The cosmos is not alien to the sacred. The Psalms erupt with it — the heavens declaring glory, the stars as handiwork, the depths of the universe as testimony to a Creator who is not made small by the scale of what He made. When Bonaventure wrote that creation helps the human mind “ascend gradually to the supreme Principle, who is God,” he was not speaking metaphorically. The cosmos is not a backdrop. It is a disclosure.
The mandate in Genesis — be fruitful and multiply, fill the earth and subdue it — has always been misread as license for domination. But the Hebrew carries the weight of stewardship, of a creature entrusted with something precious, called to extend and cultivate and care for what was given. If the earth is not the limit of creation, it is not obviously strange that the human mandate of cultivation might eventually press outward. The Church has consistently held that humans are called to develop their abilities in science and technology, for through them, God is glorified. That is not a footnote. It is a theological claim about the dignity of human creativity.
So the question is not simply whether we should go. It is who we will be when we get there.
The question is not simply whether we should go to the stars. It is who we will be when we get there.
The Missing Question
Here is where the current vision begins to falter — not in its ambition, but in its anthropology.
The world being imagined is one of extraordinary capability and extraordinary comfort. Robots that cook the perfect meal calibrated to your biometric needs. AI companions that laugh at your jokes and ask how your day went. A future in which longevity extends indefinitely, abundance reaches everyone, and the stars become the new frontier.
What is missing from this picture is interiority. What is missing is the question of formation.
One prominent voice in this movement frames the coming split in humanity as between consumers and creators — those who are served by AI and those who use AI to do bold things. That is a real distinction, and it matters economically. But it is not the deepest one. The deeper split is between those for whom abundance becomes a mirror and those for whom it becomes a window. The mirror reflects only the self back — my needs, my preferences, my longevity, my optimization. The window opens onto something else, something other, something that places demands on the one looking.
The desert fathers understood that the greatest danger of comfort is not what it takes away but what it removes the need to pursue. Acedia — the noonday demon — was not idleness exactly. It was the collapse of the longing that drives a person toward God. And history suggests that abundance, absent formation, does not produce deeper human beings. It produces more comfortable ones. The cave did not make the monks. The cave just reduced the distractions.
If we colonize space carrying the same interior architecture we have now — distracted, relationally fragmented, increasingly outsourcing attention and memory and moral judgment to machines — we will have expanded our reach without deepening our roots. We will have built those rotating cylinders full of people who do not know themselves, who cannot be still, who have never been loved in a way that required something of them.
That is not expansion. That is displacement.
What Babel Was Really About
So does the Bible contradict the dream of going to the stars? The question deserves a serious answer, not a defensive one.
The short answer is no — not inherently. Scripture is not a real estate document for planet Earth. The biblical vision of creation is not that God made a terrarium and told us to stay inside it. The cosmos He made is vast, and the tradition has always understood that vastness as reflective of His own inexhaustible generosity. There is no verse that forbids a human being from standing on another world.
But Scripture does challenge the spirit in which we go.
The tower of Babel is not a story about construction. It is a story about what happens when a civilization organizes itself around the project of its own ascent without reference to anything beyond itself. The builders were not evil in any dramatic sense. They were simply — and this is the diagnosis — trying to make a name for themselves, to secure their own permanence against the threat of dispersion. The project was driven by a deep fear dressed up as ambition. God’s response was not punishment for curiosity. It was a disruption of a unifying project that had become a closed system, a civilization turning inward.
The transhumanist vision — of which the space expansion dream is a cousin — carries this same latent temptation. Pope Leo XIV named it explicitly: the promise of “immanent immortality,” of humanity engineering its way past death, past limitation, past the conditions that make dependence on God feel necessary. The body is not a problem to be solved. Death is not simply a technical challenge. Limitation is not merely an obstacle. These are the conditions within which the person is formed, within which love becomes real, within which the soul discovers what it is actually made of.
None of that forecloses going to the stars. It forecloses going to the stars as if going to the stars is the point.
The body is not a problem to be solved. These are the conditions within which love becomes real, within which the soul discovers what it is made of.
What We Were Made For
The Christian tradition has always held a strange double truth about the human place in the cosmos. On one hand, we are small. Vastly, incomprehensibly small. The Psalmist knew this: What is man, that you are mindful of him? And yet the tradition has always insisted that the infinite God is mindful of him, that this creature of dust is somehow the axis around which the whole drama turns. Not because we are the biggest or the brightest thing in creation, but because we are the creature in whom creation becomes conscious of itself, in whom the cosmos turns back toward its Maker.
That is a high dignity. It does not become higher by adding zeros to the compute capacity. It does not diminish by staying on one planet. It is a dignity that exists in the relationship between the creature and the Creator, and it cannot be engineered upward or designed away.
If we go to the stars, the question that matters most will not be how fast we got there. It will be whether we carried anything worth bringing.
Whether the person who stepped off the ship was someone who had learned to be present, to love, to receive, to be still long enough to hear something other than their own ambition.
Whether the interior exodus had preceded the exterior one.
