stars and the universe

Luminosity is the amount of light that is radiated from a star. White light is the composition of all colors. In elements, the energy discharge can be displayed as light. Just by looking at the colors that are discharged, one may precisely identify the element. In understanding the universe, the Doppler effect is one of the most important tools. The Doppler effect is a shift in frequency due to a moving source. Skipping a rock …

…the uncertainty principle keeps the universe apart. Black holes stretch the fabric of time to an infinite extent, tearing a hole in space time. What happens at the tear?
