The question of life after death have been striking in humans mind since ancient time. Every religion and every civilization have their own view on life after death. Many believe that the body will resurrect after death while many believe that the body will not be resurrected the only soul will go with God and will remain in a place forever. Egyptian Civilization will believe firmly that body will live again after death so that they facilitate their dead body with all the useful things for the alive body. And then constructed huge mountain like shape which is known as Pyramid. But science has always a completely different view on death. They don’t believe in souls as they referred the inside things which are run our body is energy.
Death is s significant event in Islam and is not representing as a termination of life but is just a completion of our test and death is a way which will take us to our eternal destiny. After death, the dead body takes to the grave and it is believed that dead body will sleep till the final day of resurrection and after that day God will choose good souls who believed in Allah and follow his teachings and practice through all the life and send them to Jannat. And all the other sinner who never believed in Allah will send to Dozakh where they will live forever.
The quiet same theory is mentioned in Bible all the sinners who did not believe Jesus Christ as a savior will send to Hell and those who are the believer will go the Heaven for forever.
The ancient Egyptian believed in the concept of immortality although in a different manner. They believed that death is only an interruption and the soul will get its body again will make it alive again with breath and heartbeat.
In their civilization when people died they mummified their body with some special ancient chemicals which would protect their body from decomposing. And then they put their bodies in huge Pyramids with other necessary things of human lives. And they believe when they will become alive they will use these things. Written funerary texts consisting of spells or prayers were also included to assist the dead on their way to the afterworld.
The physical concept of Life after death:
Apart from these religious theories science has quite different theory about death. Science believes that our body is a combination of biological and chemical substances and after death, our dead body will decompose in its forming substance and dissolve in the universe. Through biology, no one can assume any life opportunity after death because all the component of body dissolves completely in nature again after the death.
But physics has a different view about death. Physics asserts that our body made up of two components one is matter and the second is energy. The matter is a combination of chemical and biological components but the thing which provides life to our body and changed it to a living body is energy. And physics also says that energy can not be created and can not be destroyed.
In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions). The same can be said about plants, which are powered by photosynthesis, a process that allows them to generate energy from sunlight.
The process of energy generation is much more complex in humans, though. Remarkably, at any given moment, roughly 20 watts of energy course through your body — enough to power a light bulb — and this energy is acquired in a plethora of ways. Mostly, we get it through the consumption of food, which gives us chemical energy. That chemical energy is then transformed into kinetic energy that is ultimately used to power our muscles.
After death, our energy dissolves in this universe and remains eternal forever. Its true that our consciousness dies after our death but our energy which becomes free into this universe and never destroys. It all means that we live forever even after death. It is our body which dies and destroy but the energy consisting of our body never lasts it remains in this universe eternally. So we never have to scare of death as we know from physics that we never die, only our body destroys.
