what is DEATH and what happens aftermath ?? - a scientific vantage point...

At times i keep wondering myself about death. What is death? What happens when we die? Do we enter a different world aftermath ?

There are many theories that tell there is nothing after death..... Maybe death is just a machine fails to run and all the organs just stops..... all the memories and feelings lies no further.... But the fact still remains that these are just assumptions without any proof .

But what about those whose tell about NDE's (Near Death Experience). Are they just fake or some kind of illusion ceated by Human brain What exactly happens after death. What happens to our memories? Is it similar to destroying the hard disk of a computer?

One of my friend said hey none of them can say after death wat happens??? as much as science is concern but according to religion they have diff beliefs and if sum one who belives in god can belive in these things and their r many books which co relate wat happens after death but most of them i had read r with out proof .

And then i somehow reasoned to myself Or may be life is just a form of energy present in this universe and when someone dies, this energy beomes a part of the net energy of the universe because what ever that is present in the universe is in the form of Mass-Energy. Mass occupied by that person is somehow converted into energy and then it becomes a part of this universe.

Maybe yes when we are eaten by worms and our mass is utilized as energy by worms and then it travels the whole universe by changing from one form to another.

Having said that, dont think of afterlife stories and heaven n hell it's ofcourse not you who is travelling, face it man! you are dead! which means DEAD. No, dont think of stories to reconcile you of a beautiful heaven, with 72 Virgins waiting for you.

Here I am talking about energy not about myself. There is no life after deathits all an illusion of mind for example an Englishman will see a Satan speaking english in his dreams while an indian (hindu to be more precise) will see a yamraj speakin hindi or sanskrit its all a trick of mind... get well oh man...
