Physicists have confirmed the presence of a new type of ‘four neutron-no proton’ particle

For several decades, researchers have been trying to prove the presence of tetraneutrons and now we seem to have promising results in this regard. Japanese scientists have found evidence of a particle that consists of four neutrons and does not include any proton structure. According to theories issued so far, the presence of this particle was impossible to detect because it is known that lone neutrons are unstable. Physicist Francisco-Miguel...
