On March 14, 2018, the world lost Stephen Hawking, a physicist many consider the greatest mind since Einstein. But his final book, Brief Answers to the Big Questions, published posthumously with help from his family and colleagues, gave humanity one last gift: his answer to the question that has troubled humans for centuries: Is there a God? Hawking approached this with characteristic directness and humor, turning what could have been a divisive topic into a meditation on the power of scientific laws to explain our universe.

The question of whether God exists has haunted humanity's greatest minds. In the nineteenth century, astronomer Maria Mitchell wrote that "every formula which expresses a law of nature is a hymn of praise to God," capturing how many scientists saw divinity in discovery. Albert Einstein faced the question when a little girl asked if scientists pray. Max Planck, a quantum theory pioneer, argued that science cannot solve nature's ultimate mystery because we are part of that mystery. His colleague Niels Bohr proposed a different approach: religions address subjective reality (meaning and morality), while science addresses objective, measurable reality. Wolfgang Pauli warned that attempts to reconcile science and religion are always "full of pitfalls." Each great scientist grappled with this differently, yet all recognized something profound in the tension between faith and reason.

Hawking's answer, drawn from his lifetime of correspondence, lectures, and personal reflections, began with a disarming personal touch. He acknowledged that centuries of tradition held disabled people like himself were cursed by God. Then came his characteristic pivot: "I prefer to think that everything can be explained another way, by the laws of nature." This was not atheism dressed up as science, but rather a careful logical step. If the laws of nature explain how things work, then calling those laws "God's work" is merely a definition of God, not proof of God's existence. The discovery of physical laws, from ancient times through Kepler and Galileo to the modern era, has been humanity's greatest achievement precisely because it explains our universe without requiring supernatural intervention.

What made Hawking's stance powerful was its intellectual humility paired with confidence in science. He did not claim to disprove God; rather, he observed that the more completely we understand nature's laws, the less explanatory work remains for a deity. The laws of nature describe how things actually work in the past, present, and future, operating consistently and predictably. This perspective did not diminish wonder or meaning; instead, it relocated them. The universe itself, governed by elegant mathematical laws, became more awe-inspiring than any mythological explanation. In his final years, wrestling with motor neurone disease, Hawking embodied a quiet courage: rather than seek comfort in appeals to divine mercy, he sought truth in the natural world.

Hawking's answer matters because it models how to address profound questions without arrogance or dismissiveness. By acknowledging the question's weight, honoring those who find meaning in faith, and then offering a reasoned alternative grounded in evidence, he showed that science and spirituality need not be enemies. The universe, as Hawking had famously written, is "the ultimate free lunch," a cosmos of stunning complexity arising from simple, beautiful laws. His final book, with proceeds supporting the Stephen Hawking Foundation and research into motor neurone disease, left future generations both an intellectual framework and a practical legacy. When his ashes were later interred between those of Darwin and Newton in Westminster Abbey, it seemed fitting: three minds united not by shared faith, but by shared dedication to understanding how nature actually works.
