The Speculāris factory at L4 and the L5 station are separated by 260 million kilometres. Connect them with the tunable dye laser communication arrays already in both facilities and you have built the most powerful interferometric observatory in human history — as a byproduct of an industrial communication network. No dedicated telescope. No new hardware. The baseline already exists.
Interferometric resolution is governed by one equation: θ = λ/D. Wavelength divided by baseline. The longer the baseline, the finer the resolution. The Speculāris L4–L5 baseline is so long that optical wavelength interferometry reaches resolution that no other instrument in history has approached — or could approach without a similarly positioned infrastructure.
At 2×10⁻¹⁸ radian resolution and nano-Hz gravitational wave sensitivity, the L4–L5 interferometer opens observational windows that are physically closed to every other instrument. Not incrementally better — categorically different science.
The L4–L5 interferometer requires no dedicated hardware. The tunable dye laser communication arrays already specified for the Speculāris communications network — 40 units across L4, Georgia, Texas, and Switzerland — provide the coherent light source. The L5 station receiver array closes the baseline. The observatory is a byproduct of the communications infrastructure.

No government funded it as an observatory. No science mission proposed it. No telescope committee reviewed it. It is a communication network between an asteroid factory and a Trojan point industrial station — and it happens to be the most powerful astronomical instrument in human history.
At 2×10⁻¹⁸ radian resolution, the nearest exoplanets are not distant specks. They are worlds with surfaces. With weather. With chemistry. With whatever is there, visible, for the first time.
Speculāris — On the cutting edge.
Project Speculāris delivers asteroid materials, rare earths, He-3, and DRAD chips as primary outputs. The L4–L5 interferometer is what happens when the infrastructure is already there.
