Something isn't measuring up. For the second time, an extremely precise measurement of the proton's mass is different from its recognized value. The issue first raised its head in 2015, when a team led by Edmund Myers at Florida State University measured the difference in masses of the ...

protons combine with other protons by means of nuclear fusion. This fusion requires a temperature of approximately 1 million degrees Celsius. This high temperature causes two lighter particles to fuse into a third particle. The mass of the created particle is less than that of the two initial pa...
Protons are ubiquitous in the universe. They are found in the nuclei of all atoms and play a crucial role in how stars shine.
