If the cosmos is infinite, it is infinite. On the Big Bang, it was constantly dense. Space has gotten less dense since that time. The hyper-sphere would not have adequate curvature in the infinite situation.Answer and Explanation: Naturally, the observable Universe is considerably larger. ...

Neutron stars are formed when a supermassive star runs out of fuel and collapses. They have a mass similar to that of our Sun, squeezed into a ball just 20km wide. Any denser, they would become black holes. “While dark matter is the dominant type of matter in the Universe, it is ...
Atomic bombs use fission to split the nucleus of an atom into two smaller fragments with a neutron, causing a deadly chain reaction. H-bombs go the other way and use fusion to bring together two smaller atoms to form a larger one. That creates massive energy in a reaction similar to the...
Baron, Eddie: Astrophysics: How big do stellar explosions get? Nature 395, 635/636; 663-674 (1998). We thought we knew how powerful su- pernova explosions could be. We also thought that supernovae explosions and y-ray bursts were unrelated. One extraordinary supernova is making us re-...

How big is a photon compared to an atom? How did Niels Bohr describe electrons in his atomic model? How are subatomic particles responsible for an atom's characteristics? Can an atom become charged? If so, how? How to find the energy of quantum light ...
The year we learned of a "Dark Big Bang"? Understanding how dark matter was originally created could tell us more about what it is. A new theory, from Katherine Freese and Martin Winkler at the University of Texas at Austin, describes a "Dark Big Bang" that produced dark matter particles...
