Here's why:
* Mass is a continuous spectrum: Stars can have a wide range of masses, from very small to extremely large. There isn't a sharp line between "low mass" and "high mass". It's a spectrum.
* Different properties: Low-mass stars and high-mass stars have vastly different properties, including:
* Lifespan: Low-mass stars live much longer than high-mass stars.
* Temperature and Luminosity: High-mass stars are hotter and brighter than low-mass stars.
* Evolutionary path: They go through different stages of evolution.
Therefore, it's not accurate to say that they are inversely or indirectly related. They are simply two different categories of stars with distinct characteristics.
