About Electronvolt mass
In particle physics, mass and energy are interchangeable via Einstein's E = mc². The electronvolt (eV) as a mass unit equals the mass equivalent of 1 eV of energy (approximately 1.783 × 10⁻³⁶ kg). Particle masses at the subatomic scale are routinely expressed in MeV/c² or GeV/c² - the proton mass is 938.3 MeV/c², and the electron is 0.511 MeV/c². The Higgs boson, discovered at CERN in 2012, has a mass of approximately 125.25 GeV/c². This unit is exclusively used in high-energy physics and quantum field theory, where conventional mass units like grams would require impossibly small exponents.
About Solar Masses
A solar mass (M☉) is the mass of our Sun - approximately 1.989 × 10³⁰ kg - and is the standard unit for measuring stellar and galactic masses in astronomy. The Sun contains 99.86% of the total mass of the Solar System. Stellar evolution models describe stars of 0.08 M☉ (the minimum for hydrogen fusion) to over 200 M☉ (the most massive known stars). Supermassive black holes at the centres of galaxies range from millions to billions of solar masses: the black hole at the centre of the Milky Way (Sagittarius A*) is approximately 4.3 million M☉.
