Event Horizon is Michaela Gleave’s first major solo institutional exhibition. Taking over the main galleries at Artspace, the large-scale installation bringing together light, sound, atmospheric materials, geological matter and performance to explore the limits of observation and knowledge. Drawing on ideas from astrophysics, quantum physics and Earth sciences, the exhibition considers what happens at the edges of perception, where measurement becomes uncertain and new ways of sensing and understanding the world begin to emerge.
In physics, an event horizon marks the boundary around a black hole beyond which information cannot return to an observer. It is not a physical surface, but a limit placed on observation by the structure of spacetime itself. Gleave uses this concept as a way of thinking about the boundaries of knowledge: the point where familiar frameworks fall away and inference, intuition and imagination take their place.
Rather than presenting discrete objects, the exhibition unfolds as a series of interconnected environments that visitors move through. Light, sound, vibration and shifting atmospheres create perceptual fields that draw attention to the act of sensing itself. Subtle changes in energy and environment invite audiences to attune to processes that are normally invisible or imperceptible.
The exhibition is organised into four movements: Reading Room, Quantum Field, Organic Realm and Entanglement Field. Each explores different relationships between matter, energy and systems of knowledge.
Running throughout the exhibition period is Universal Maintenance, an ongoing performance series in which Gleave periodically enters the galleries to tune, adjust and recalibrate the installation. These acts of maintenance treat the exhibition as a living system, allowing it to shift and evolve over time.

“Event Horizon urges its audiences to walk inside shifting air, breathe it in and feel it rearrange understanding in what feels like a passage from one reality to another.”
“Strange, vivid and completely absorbing, Event Horizon is an opportunity to challenge the world around you, and experience a contemporary artist operating at the full breadth of her vision,”
“Event Horizon epitomises Gleave’s commitment to making tangible the invisible forces that govern our reality.”
