Here's why:
* Fuel Consumption: Red dwarfs burn their hydrogen fuel very slowly due to their low mass and temperature.
* Nuclear Fusion: Their core temperatures are relatively low, meaning nuclear fusion occurs at a much slower rate.
* Gravitational Pull: Their weak gravitational pull means they don't need to burn their fuel as quickly to maintain stability.
Estimated Lifespan: Red dwarfs are estimated to live for trillions of years, far longer than the current age of the universe.
In contrast, larger stars like blue giants have much shorter lifespans, burning through their fuel much faster due to their higher mass and temperature.
