STEGANOGRAPHY is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos (στεγανός), meaning "covered, concealed, or protected", and graphein (γράφειν) meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia , a treatise on cryptography and steganography, disguised as a book on magic.

For example, the hidden message may be in invisible ink between the visible lines of a private letter. The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages—no matter how unb...
BLACK HOLE ? A black hole is simply "an exhausted star with no energy in it to burn itself or let the nuclear fusion reaction to let happen". So do you thing a black hole let's you travel through the time and escape it's gravity? What would be left in it to cause the gravity? or it would be a wobble of nothing remaining? or would it be any dark matter as the space is mostly composed of it? If the black hole is feeding itself then it is for itself to gain a huge amount of energy and then let the fusion reaction happen again creating a supernova or hypernova (according to the size of dead star) explosion and then a star is formed back again!!!

The day we are about to die, get a strange vibe that we miss our mother, father and the whole family of ours ! We think about the friends that we had made and strange places we visited, the food we ate and the pets we had. These all of sudden form nowhere come in mind actually waking us up what had been we doing all our life? and thus this day we search what where we doing. For the people who see us from their prespective, think that we are not having a peaceful time while dying ! They say that our souls are feeling uneasy to leave our bodies, yet we are just in the subconscious phase of the black path that has no eternal light at it's end. Death is finally and literally a period of life that has nothing in it no light, no sense, no ot...
