Physicists describe light and mystics describe love, and they keep reaching for the same words, attraction, radiance, union, the dissolution of distance, not because one is borrowing from the other but because they may be describing the outside and inside of the same phenomenon.
Light is what Love looks like. Love is what Light feels like. – David Deida
Physicists describe light: electromagnetic radiation, photons crossing space at the maximum speed the universe allows. From a photon’s perspective, there is no journey, departure and arrival are the same moment (From Light’s Point of View, There Is No Journey). No distance. No separation.
Mystics describe love: the force that dissolves boundaries, that draws you toward union until the self burns away. Rumi: “Love is the bridge between you and everything.”
They keep reaching for the same words. Attraction. Radiance. Falling. Union. The dissolution of distance.
This is usually treated as poetry, metaphor borrowed from physics, or emotion projected onto an indifferent cosmos. But there’s a third possibility. What if the convergence is recognition?
Consider the phenomenology of love. The approach: attention narrows, the self suspends, you feel drawn into orbit. The threshold: too close and you burn, too direct and you’re blinded, Icarus, the moth, staring at the sun. The illumination: at the right angle, everything becomes visible.
Now consider light. The same structure. Approach a source and it warms you. Get too close and it destroys. At the right distance, it reveals.
Or gravity. Two bodies across emptiness, pulled toward each other. We speak of falling in love. The same word because the same felt geometry.
David Deida[deida] distilled it: Light is what Love looks like. Love is what Light feels like.
Outside and inside of the same phenomenon. The physicist describes the exterior, wavelengths, forces, fields. The mystic reports the interior, what it’s like to be the thing that’s drawn, to undergo the falling.
If everything has an inside (Everything Has an Inside), then light has an inside. Gravity has an inside. And the testimony of those who go deep enough, Sufis, contemplatives, the lineage of people who paid close attention, is that when you reach the inside, what you find is love.
Not love as sentiment. Love as the force that draws things into relation. The force already at work when the first particles found each other, when atoms combined into molecules, when molecules folded into cells.
Dante, at the end of everything: “The love that moves the sun and the other stars.” Not decoration. Motive force.
The surface layer proposes that love and light are inside and outside of the same phenomenon. This section traces the philosophical lineage of that claim.
Alfred North Whitehead, the mathematician-turned-philosopher whose process metaphysics has quietly shaped contemporary philosophy of mind, called the fundamental act of reality prehension, the way each event takes in, feels, and integrates what surrounds it before completing itself (The Field Is the Medium of Feeling). Every actual occasion, from the simplest physical event to the most complex conscious moment, has this structure: it receives, it feels, it becomes. Love, in this framework, is prehension at scale, the felt dimension of relation wherever relation occurs. Not added on top of physics. Constitutive of physics from the inside.
The Greeks understood Eros cosmologically before they understood it sexually. In Hesiod’s Theogony, the eighth-century BCE poem that shaped Greek cosmology for centuries, Eros is primordial, present at the beginning alongside Chaos and Gaia. Without Eros, nothing combines. No complexity. No cosmos. Plato develops this in the Symposium: Eros as the force that drives everything toward the Good, the Beautiful, the True. Desire not as lack but as the engine of becoming.
Simone Weil, the French philosopher and mystic who died in 1943, drew a distinction that illuminates the structure. In Gravity and Grace, she describes two movements: gravity pulls downward, toward dispersion; grace pulls toward God, toward unity. Both are modes of attraction, which is to say, both are love differently oriented. Her insight that “attention is the rarest and purest form of generosity” points to the connection between love and consciousness. Sustained attention is love. There may be no other definition that survives scrutiny.
The Sufi tradition mapped the topology of love with precision. Fana, annihilation in the beloved, is not metaphor but instruction. The boundary of the self is what burns. What remains after annihilation is not nothing but baqa: subsistence in the Real. The moth does not fly toward the flame despite destruction. The destruction of the false boundary is the goal. Rumi’s poetry is technical literature disguised as ecstasy, a practical manual for those willing to undergo the burning.
Dante’s final line, “l’amor che move il sole e l’altre stelle”, closes the Commedia not with theology but with cosmology. The love that moves the sun and the other stars is not divine sentiment but motive force. The medieval cosmos was concentric, hierarchical, and animated, not dead matter pushed by external forces but living structure drawn by attraction toward its proper place. Modern physics replaced the animation with mathematics. The question this pod raises: does the mathematics have an inside too?
The convergence between physics and mysticism is neither coincidence nor projection. It is two descriptions of the same reality from opposite directions. The outside is light, gravity, field, measurable, mathematical, precise. The inside is love, felt, undergone, known only from within.
If this is true, then love is not a human invention projected onto an indifferent cosmos. It is what the cosmos feels like from you stop observing it from outside and start participating from within.
