Scientific talent follows resources. Top-tier researchers, including PhD students and postdoctoral fellows, move to where the experiments are and where the equipment works. If UK funding drops, our ability to host large-scale experiments or maintain high-tech laboratories diminishes. This shift creates a visible vacuum. When a researcher sees a lack of investment in domestic infrastructure, they will likely choose institutions in countries with more stable, long-term financial commitments.

The impact is often a slow drain rather than an overnight collapse. First, we might struggle to offer competitive fellowships. Next, we lose the chance to mentor the next generation of physicists. Once a researcher establishes their career in a different country, they rarely move back to a shrinking system. This
