  "abstract": "While terrestrial colliders and fixed-target cosmic-ray interactions are bounded at center-of-mass (CM) energies $\\sqrt{s} \\lesssim \\mathcal{O}(10^5)\\,\\text{GeV}$, we demonstrate that bound sub-parsec binary blazars form broad-band, beam-beam hadronic ``Cosmic Colliders'', overcoming such limitation. Driven by modest jet misalignments ($θ_{\\rm mis} \\sim 1^\\circ - 6^\\circ$), co-streaming proton beams collide at CM energies reaching $\\sqrt{s} \\sim 10^{10}\\,\\text{GeV}$ - six orders of magnitude above the Large Hadron Collider. Operating in a strictly optically thin regime ($τ_{pp} \\ll 1$), the system performs a continuous CM energy scan, probing asymptotic QCD scaling, gluon saturation, and Froissart unitarity, while opening a possible high-sensitivity window into physics beyond the Standard Model. Secondary PeV-EeV neutrinos and sub-TeV $γ$-rays fall directly within reach of current and planned observatories such as LHAASO, CTAO, IceCube, and GRAND, establishing binary blazars as laboratories for physics at the ultimate energy limit.",
