The Theosophical Society was formed by Helena
Petrovna Blavatsky, Henry Steel Olcott, William Quan
Judge and others in November 1875 in New York. The
aim of the society was to promote spiritual principles
and search for truth known as Theosophy.
Black holes are regions of spacetime from which
nothing, not even light, can escape. A typical black
hole is the result of the gravitational force becoming
so strong that one would have to travel faster than
light to escape its pull. Such black holes contain a
spacetime singularity at their centre
The amount of water vapour in the air at any given time
is usually less than that required to saturate the air.
The relative humidity is the percent of saturation
humidity, generally calculated in relation to saturated
vapour density. Relative Humidity = actual vapor density / saturation vapor density x 100%
