Event horizon

Entrance and exit point of an object's journey through the Stargate where matter is disintegrated and then reintegrated. The event horizon appears to be a bright, iridescent pool of water, standing completely vertical within the ring of an active Stargate.

The Stargate is smart enough that it attempts to determine whether or not an object is attempting to pass through a connected wormhole based on way in which pressure is applied to the event horizon. A person or object sent through will feel no resistance; but if the gate is, say, activated under water it will not flood water through the wormhole.

An object or body part can also be extended through the event horizon and then pulled back, at which point it will instantly rematerialize. Holding one's arm inside the event horizon of the receiving Stargate (having not yet come all the way through the wormhole), however, will temporarily prevent both connected Stargates from shutting down.
