DESCRIPTION: ABSTRACT: What are the essential aspects of quantum theory ne
 eded in order to understand compact relativistic objects? Relying solely o
 n universal properties of QFTs at high energies\, we show that as a star c
 ontracts towards its Buchdahl (rather than its Schwarzschild) radius\, the
  effects of the trace anomaly become macroscopic at densities much below t
 he Planck scale. The consequences of this may be observable\, as we illust
 rate with minimally coupled scalar waves.
