What Happens When We Die?


What happens when we die? While no one has ever truly risen from the dead to tell us, the living and describe exactly what happens after death, there are scientifically proven facts of what actually happens to our bodies. Of course, there are different religious beliefs about death but none of those has truly been proven. There is no evidence that life after death exists. Here are some of the different religions and how they deal with their dead.

What we will look at are evidence based facts of what actually happens to the human body after the breath of life has left. If you’re curious to know, here are the 10 strangest cause of an earlier death. You should also take a peek into the top 10 strangest deaths in history.

The Physics of Death

Biologically, as with other living organisms, the body decomposes after death. The heart stops pumping blood, the brain stops functioning, we lose consciousness and slowly, the body and all its parts will deteriorate until nothing is left, except our names in the cemetery. There is no rocket science as to what becomes of the human body in death.

But let’s explore the perspective in the physics of death. We are energy, just like other organisms in the universe including the sun and the moon. So let us look at how our energy is redistributed after we die to understand what happens when we die.

  • Matter and Energy

    The human body comprises matter and energy. This energy is electrical and chemical. Roughly 20 watts of energy courses through the human body which is sufficient to power a light bulb. We get this energy from consuming food that gives us chemical energy. It is transformed into kinetic energy that then powers our muscles.

  • Energy Cannot Be Created Nor Destroyed

    In the law of thermodynamics, in trying to understand what happens when we die, energy cannot be created nor destroyed. It only changes its state. We exchange energy with our surroundings. We gain energy and lose it. During death, the collection of atoms in your body is repurposed. Your “light” or the essence of your energy will continue to echo throughout space until the end of time.

Your Energy is Still Around

In a beautiful speech by the physicist Aaron Freemen, he masterfully explained what happens when we die in a way that’s comforting to anyone who has ever lost a loved one.

He said that if a physicist were to speak at your funeral, you’d want them to tell your grieving family about the conservation of energy to make them understand that your energy has not died. All your energy, every vibration, every wave of a particle of you remains in this world.

You want the physicist to tell your spouse that all the photons that bounced from you were gathered in her eyes and will go on forever. And according to him, in explaining what happens when we die, “…you hope that your family will examine the evidence and satisfy themselves that the science is sound and that they’ll be comforted to know your energy’s still around. According to the law of the conservation of energy, not a bit of you is gone; you’re just less orderly.”
