... 13. Observations have identified faint, distant galaxies at the locations of a number of gammaray bursts. 14. Both gamma ray bursts and supernovae are thought to occur when the core of a massive star collapses. 15. Most of the energy is released in the form of neutrinos. 16. The bright radio emissio ...

... Electric charges can also be surrounded by magnetic fields. All moving electric charges are surrounded by a magnetic field. The motion of electrons creates a magnetic field around the object they flow through. A change in one field causes a change in the other. III. Making Electromagnetic Wave ...
