I myself believe that there will one day be time travel because

Hear the words of David Deutsch, a thinker who dwells in the farthest reaches of imagination and reason: “I myself believe that there will one day be time travel because when we find that something isn’t forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.” This is not mere speculation but the voice of faith in the power of human inquiry. For he speaks of a law as old as civilization itself: that what is possible in nature will one day be seized by the hands of humanity.

The essence of his saying is that possibility precedes achievement. The universe is governed by laws that cannot be broken, yet within those boundaries lies a vast field of potential. If time travel is not forbidden by these higher laws, then the question is not “if,” but “when.” Humanity, restless and unyielding, has always turned the possible into the actual. What once was myth becomes science, what once was dream becomes tool. This is the heroic arc of civilization: the transformation of wonder into reality.

History itself proves his words. Once men looked at the sky and declared, “Flight is for birds alone.” Yet the laws of physics did not forbid wings of wood and engines of steel, and so the Wright brothers, through persistence and faith, rose into the air. Once it was said that to speak across oceans was impossible, yet no law of physics forbade the transmission of voices through waves of light, and so the radio was born. Time and again, what was thought impossible was revealed as ignorance rather than prohibition. Deutsch’s faith is born of this lineage: what is permitted by nature can eventually be mastered by humankind.

This echoes even the wisdom of the ancients. Consider the legend of Daedalus, who fashioned wings of feather and wax, striving toward the freedom of the heavens. Though myth, his tale foreshadowed the truth: that man’s longing to transcend his limits is eternal, and that in time, such longings bear fruit in real achievement. What Daedalus dreamed, others eventually accomplished, not through wax but through the steady unlocking of physical law. The myth became prophecy, and the prophecy became history.

To speak of time travel is to speak of the greatest frontier of all: the mastery of time itself. Though today it lies in theory and speculation, Deutsch reminds us that the seeds of possibility lie within the soil of physics. The same laws that bend light, warp space, and govern the stars may one day open the doors of past and future. To dismiss this dream is to forget that every tool of power—the wheel, the compass, the engine, the computer—was once regarded as impossible or absurd. Humanity advances not by certainty, but by daring to believe that the forbidden is rare, and the possible is vast.

Yet there is also wisdom in humility. For though the laws may permit, achievement is not guaranteed. The road is long, filled with failure and sacrifice. Great endeavors demand patience across generations. The builders of the first telescopes did not reach the stars, but they gave the gift of vision to those who would. Likewise, the pursuit of time travel may span centuries, but the dream itself fuels the onward march of knowledge.

The lesson, then, is this: do not fear the immensity of possibility, but embrace it. If the universe does not forbid a thing, then the path is open, though long. Let us, then, honor curiosity, foster science, and train our minds in the art of wonder. For the treasures of tomorrow are hidden not in magic, but in the faithful unlocking of what is already written into the cosmos.

Thus, Deutsch’s words endure as a torch for all seekers: the laws of nature are not our prison, but our guide. If time travel is permitted, then one day, through courage and persistence, it shall be ours. And in that triumph, as in all others before, humanity will once again prove that its destiny is not to bow before the possible, but to claim it.
