Fundamental constants are crucial for comprehending physical mechanisms, buttheir measurements contain uncertainties due to experimental limitations. Weinvestigate the impact of system temperature on these uncertainties usingnearby white dwarfs observed in the Gaia Early Data Release 3 (EDR3) survey.Using the structures of these white dwarfs, we show that the variation insystem temperature can affect the accuracy of measurements for fundamentalparameters such as the fine-structure constant and the proton-to-electron massratio. This exploration emphasizes the importance of considering the energy ofa system while putting bounds on the values of fundamental constants.
