# Physical object **Trait Number:** 1 **Layer:** Physical **Bit Position:** 1 **Binary Encoding:** `10000000 00000000 00000000 00000000` **UHT Code (self-encoding):** `80 00 00 00` --- # Icon ![[Icon1.png|200]] --- ## Definition The entity **exists materially** in space and time. It has a tangible presence and is composed of matter or energy in a spatial frame. --- ## When to Apply Use this trait when the entity: - Has physical form or occupies space - Exists independently of abstract definition or symbolic meaning - Is not purely conceptual, virtual, or informational Avoid applying if the entity is: - A rule, value, signal, or purely symbolic reference - Represented only in software or thought unless physically embodied --- ## Related Traits - [[02 00 00 00 - Material Form]] — More specific to *composition*; an object can exist but be immaterial (e.g., force fields). - [[04 00 00 00 - Perceptible]] — Perception implies sensory access; an object might be too small or distant to perceive. --- ## Examples - A rock - A smartphone - A chair - A planet - A printed book (not just the text it contains) --- ## Commentary This is often the most “default” trait and is shared by nearly all tangible systems. Be cautious not to conflate "physical object" with "man-made" or "perceptible" — something can exist physically yet not be designed or sensed. --- **© 2025 Steven Holland.
