https://tube.pompat.us/videos/watch/455faf28-fd20-4388-81c0-3354644236cd An animated explainer showing how ultralight scalar fields — a candidate for dark matter — can form a dense halo around a binary black hole system. Based on research from Roy et al. (2025), arXiv:2510.17967. The scalar halo extracts orbital energy from the binary, producing a unique gravitational-wave signature that LIGO could detect. This animation shows a cross-section of the halo reaching ~480 km radius at densities around 10⁹ g/cm³, with spiral density waves transporting energy out of the binary orbit.
