Advances in space travel technology allowed for quicker transportation of materials and equipment to Paliputra. Silgarga's bone is buried in a tomb of concrete and rebar, the surface above is fortified, and on this day a new facility is completed on a different site to analyze its activity remotely and (hopefully) safely.
Safety improves only marginally after these changes. Comprehension is a greater hazard than exposure, resulting in greater, subtler complication, albeit with notably fewer fatalities.
