how many other windows a thing holds open

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [hold](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-hold.physical), [open](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-open.spatial)

**Through:** Weight emerges when holding a thing in place requires maintaining it within multiple parameter ranges, each associated with an open boundary that permits change, increasing the physical load.

**Novel properties:**
- collective load
- distributed constraint
- mechanical dependence

## Examples
- The International Space Station maintains orbit by countering atmospheric drag with periodic reboosts from docked spacecraft. *(engineering)*
- A neutron star holds open spacetime distortions detectable by LIGO, sustained by its immense mass and rapid rotation. *(physics)*
- The Svalbard Global Seed Vault remains accessible year-round due to permafrost and active cooling preserving its entrance tunnel. *(institutions)*
