Established astronomical knowledge had it that galaxies with two nuclei were very rare. Experts believed that small galaxies had one made up of a star cluster, whereas the more massive ones had a black hole at their cores. But a new study comes to prove that the double-nucleus galaxy is, in fact, not that rare of an ... |

The current standard models postulate that quarks and leptons are the basic building blocks of all matter. However, in the 1970s, some scientists argued that quarks are not fundamental particles, but are themselves composed of other smaller particles called preons. Though the preon particles sparked a lot of excitem... |
