The thought experiment is now famous. A cat in a sealed box, an atom whose eventual decay triggers a lethal mechanism. So long as the box remains closed, according to one interpretation of quantum mechanics, the cat is both dead and alive. It is the lifting of the lid, the observation, that decides.

Schrödinger, who devised this allegory, did not care for the image; he had conceived it to underscore the absurdity of a literal interpretation of his own theory. History has retained it for precisely the opposite reasons: it captures, better than any equation, the strangeness of what twentieth-century physics discovered. The real, at the scale of particles, does not precede observation the way a landscape awaits its wanderer. It comes into being in the act of being measured.

This is, without doubt, what happens to the astrologer who, upon learning of an event, sets about visualizing and confirming it. A few days ago, the body of Canadian actor Stew McLean was discovered, presumed murdered. I turned at once to the section of my website where I attempt, amateur that I am, to converse with the stars.

Anyone can go to Calculate your chart, enter their birth data and obtain various readings, including, under the Major Transits tab, the graph below (the Annual Trends button must be pressed to compute a full year).

The calculation produces a daily score, a weighted sum of transits to the natal chart. The higher the curve climbs, the denser the transit load. The system is precise, configurable, and transparent in its formula. And it is, deliberately, blind to meaning, for this score knows nothing of the nature of the configuration. It knows its intensity. It knows that on a given day, a certain number of exact aspects have accumulated, weighted according to the slowness of the transiting planet and the centrality of the natal point it touches. Of the rest, it knows nothing.

The ambition underlying the platform's transit scoring system is deliberately modest. It is not a matter of predicting the future, but of quantifying the raw "transit load" over a given period and isolating the background noise in order to identify zones of high density. And yet, when set against the reality of events, the pure metric reveals its limits and draws us into the realm of quantum symbolism.

Take the case of Stew McLean. His disappearance was reported on May 18, 2026, and his remains were found four days later. We do not know the actor's birth hour, which precludes our determining the angles and the Moon's position.

Probable death on May 18–19. On the annual graph, this period is not a peak. Raw score: 16.64; seven-day smoothed average: 14.48. Dozens of other days in 2026 show a higher load. Had we not received word of his death, nothing would have flagged this date.

And yet, when one opens the detail panel, the signature is less equivocal:

• Sun in opposition to Uranus: brutal rupture, the unforeseen.
• Mars conjunct natal Mercury: aggression directed at speech and the mind.
• Mars conjunct the natal Sun/Mars midpoint: Mars upon the point of vitality and combativeness.
• Mars conjunct the natal Mercury/Mars midpoint: Mars upon "the words that wound."

Four activations by the same transiting planet upon a natal cluster are thematically coherent: sudden violence following a verbal confrontation? The pattern speaks far more clearly than any peak in the curve. But this pattern did not appear in the graph until we looked for it.

The astrologer, of course, possesses other techniques for exploring an event. One thinks here of directions by arc, which in McLean's case place directed Saturn opposite natal Chiron… But since I know neither the hour of his birth nor, still less, the life of this actor, I will go no further.

In quantum mechanics, a particle does not exist at a single, determined location until it is measured. It resides in a superposition of states: a wave of probability. It is the act of observation, the collapse of the wave function, that compels the particle to choose a concrete reality.

Modern astrology operates by the same paradigm. A planetary transit is not a rigid decree consecrating an inevitable event; it is a field of semantic potentialities, a superposition of latent meanings.

When Orbiscantus calculates a daily score, it aggregates major and minor aspects and midpoint configurations, applying strict coefficients (the weight of the transiting planet, the sensitivity of the natal point touched, and linear decay according to the orb). This mathematical score represents the wave function of the day: a global measure of available energy, in the form of a tension curve.

But the curve, by itself, remains mute. It indicates the magnitude of the wave, but does not specify whether it will water a thirsty land or destroy a dike. It is the eye of the astrologer, bending over the fine structure of the sky, that causes this wave function to collapse and brings forth its deeper meaning. The raw score is only an energetic indicator. It is the qualitative observation of celestial geometry that releases the semantic content.

Before the event, Stew McLean's chart contained, as do all charts, a considerable number of configurations in waiting. Mars strikes Mercury: this may signify a dispute, a hurried journey, a text written in fever, a cutting phone call, or an accident involving speech. Mars activates the Sun/Mars midpoint: this may be victory in athletic competition, surgery, a sharp physical reaction, or violent death. Each of these readings is possible within the symbolic frame. None is given.

The event occurs. The news breaks. The astrologer returns to the chart, now with a precise question. And in the immense field of possible readings, a configuration begins to shimmer, to detach itself from the background, to organize around itself what had seemed diffuse. Mars, conjunct Mercury, begins to say what it says in this particular case: speech as battlefield. Mars on Sun/Mars no longer speaks of competition, but of physical combat. Mars on Mercury/Mars no longer voices written vehemence but the fatal altercation.

The meaning was not invented. It was already there, in the palette of symbolic significations proper to each factor. But it took the observation, the knowledge of the event, for a particular reading to detach itself and appear, in retrospect, obvious.

This is the collapse of the wave packet, in its astrological version.

But it is not always so evident, even with this kind of graph. Let us repeat the exercise with the murder of the Reiner couple committed by their son…

The physicist knows that his instrument does not passively register the real. The detector transforms what it measures. The choice of apparatus determines what will be observed: to set up a double-slit experiment is to summon the wave; to add a path detector is to call forth the particle. The same photon will respond differently depending on the question one puts to it.

The astrologer is, at his scale, this apparatus. His question, his framework, his training, and the context of the analysis all orient the reading that emerges from the chart. Two astrologers bent over the same chart, on the same day, will not see exactly the same configuration come to life, because they are not questioning the sky from the same position.

This does not disqualify the discipline. It clarifies its nature. The scoring system I document on Orbiscantus is, by construction, a tool for spotting: it flags dense days, while claiming to know nothing of their content. The qualitative reading remains the work of the astrologer, and the final meaning appears only at the point of encounter between the symbolic configuration, the lived event, and the observer who joins them.

To think of this practice as one thinks of a quantum measurement helps me hold together two demands that seemed contradictory: to take astrology seriously in its symbolic precision, without granting it a predictive power it does not have.

The sky is not a film that unfolds without us. It is an open score in which each day offers several simultaneous readings. It is the event and the gaze we bring to it that, in the end, decide which voice will be heard. The key to the mystery will always reside in qualitative examination. The astrologer cannot be replaced by the machine, for the machine calculates the potential, while the human mind, through the sacred act of observation, releases the meaning. The sky is a text that needs a reader in order to exist.
