Seeing Past the Light: Measuring the Real Edge of the Universe Through Field-Based Drift Mapping

This updated version (v1.1) expands on the original proposal for measuring the true edge of the observable universe using USP Field Theory. It adds a new section proposing a time-sharing strategy with existing telescopes (Hubble and James Webb), demonstrating that the project can begin today using regularly scheduled observations to gather long-term angular drift data. Most significantly, it includes a 100+ year vision: telescopes orbiting with Pluto and Neptune will naturally drift into vastly separated positions, creating a permanent, growing cosmic measurement system. This "century-spanning observatory" will provide progressively sharper galactic positioning data across deep time — enabling the first true 3D cartography of galactic drift and origin. With this extension, the paper bridges short-term feasibility with long-term cosmic infrastructure — laying the foundation for future civilization-scale astronomy.
