Gravitational singularity A gravitational singularity (sometimes called a spacetime singularity) is a term used to describe the center of a black hole where gravity is thought to approach infinity. In the center of each black hole is a singularity, a point where infinite density develops as spacetime approaches it. Spacetime goes toward infinite curvature and matter is crushed to infinite density under the pull of infinite gravity.

Pulsatile Tinnitus â Causes, Symptoms and Treatment Pulsatile tinnitus is different from normal tinnitus because it manifests itself as a rhythmic noise in the ears that occurs at the same rate as the pulse. It is also called vascular tinnitus. This is due to the fact that it almost always has a vascular cause. People who suspect they may have it can feel the pulse on their wrist and see if it coincides with the sound in their ears. Like other types of tinnitus, it is not caused by any external sounds. It may be constant or occur only at times.

Metals The reactivity series of metals was deduced by performing several experiments in the lab which enabled scientists to arrange metals according to their reactivity with dilute acid, oxygen (air), and water.xides of iron and copper are insoluble. Metals that are less reactive than copper like silver, gold and platinum do not react with oxygen. Note: When aluminum reacts with oxygen, a layer of aluminum oxide adheres and covers the aluminum.
