Why You Shouldn’t Fear Death


One thing I can say about you right now, is that you are going to die, and yes this is scary,that is why today i am going to use scientific principles to help you understand and cope with the inevitableending of your life.



Grade 7 was the first i ever processed the concept of dying. I remember freezing in my tracks and thinking, wait so, this is all  just going to end? Mommy! I eventually agreed with my own brain to suppres this fear and just go through the motions of  life.
I put excessive energy into schoolwork, got pimples, started date girls, realizing I only wanted to to themabout the Lizzie McGuire movie, so I started dating guys, but it wasn't until my brilliant high school teachers made me fall head over heals in love with science, that a healthy perspective on death began to emerge.

Your body is controlled by genes that code for proteins that lead to the formation of neural impulses that make constantly search out for meaning in life.
This was first shown in a slightly violent study in the 1960. Participants visualized videos of victims suffering  electrical shocks. the participants watching the videos would harshly judge the victims of the shocks as bad people.



Psychologists and bioligists began to posit that humans feel an inate impulse to create meaning. In this case if you had to watch someone get electrically shocked, then they must have deserved it. It is now understood that according to your biology, you and everyone else on the planet will constantly be looking for meaning to life, and to death. So according to science at least you know you're not alone in any attempt to explain your own death.



Now lets zoom out . Look at the night sky and you see the milky way galaxy full of an estimated 100 billion stars. That is is just one galaxy, there this a billion other galaxies in our observable universe, which is only expanded and getting bigger. How can we matter in such an expansive universe? Well, put both of your firsts together like this. That is roughly the size of your brain. An organ that has evolved over millions of years to have 86 billion neurons and even Glial cells to support it. There are more cells in your brain than stars in the milky way galaxy. You have an incredibly biological machine tucked wonderfully into your skull right now, that is astonishingly capable of conceptualizing the very idea that our universe is huge, expanding and vast.

Science essential proves you are exceptionally smart. Before you die, you have unique opportunity to live a complex and wonderful life. Like all other forms of life on earth, you are made of atoms and atoms and molecules smashing into one another, absorbing energy from your environment, but unique to you, in your amazing brain, is the ability to contemplate your actions, make decisions, and care.



Now let's zoom in. As a science teacher I know you should all remember drawing  the electron diagrams of the first 20 elements of the periodic table. This is part of most, worldwide, high school science curriculum's. If you don't remember doing that, then on behalf of all science teachers everywhere... clap clap Eyes on the board please? Thank you. Can we all pay more attention in class?
These diagrams were meant to show you that everything in our known universe is made up of protons, electrons, and neutrons. Yes we can get even smaller into the realm of quarks, Bosons or neutrinos, in fact, the sun is constantly emitting neutrinos with 100 trillion of them passing through your body every second. But let's stay on topic, we're talking today about death. We'll save neutrinos for another day. These protons, neutrons and electrons are all governed by forces that help explain, well, everything. How you evolved how you move, and yes, most importantly, how your phone works (hello?) You can describe your whole life based on the positions , velocities, and orientations of all of these atoms in your body, and this is called kinetic theory.

You can use the kinetic theory to explain how plants absorb energy from the sun through photosynthesis. We eats plants or animals that have eaten  plants, in order to gain that energy. Our bodies use that energy to power the process of the special molecule a called ATP, which powers every part of your life.

Muscle contraction, transporting molecules throughout the body, synthesizing DNA etc. And yes, ATP is synthesized in the mitochondria, making the mitochondria the powerhouse of the cell.
Infact, to stay alive, you'll typically create and use your whole bodyweight inATP molecules in one day. But, this also means that according to the kinetic, theory, regardless of your religion or spirituality, dying means that life as we know it ends. As your body loses the capability of creating ATP, and you start to physically fall apart. And one study found that when given the option to essentially produce ATP forever and live for eternity, overwhelming people said no, they want to eventually die. The fact that death is looming is what makes life so special. And in a wonderful way, death is really the only thing that we all have in common. In many ways, death is the meaning of life.
Also passionately learning about science offers the unique opportunity to grasp what science can't explain.

And knowing what science doesn't know can bring clarity. Takes these 3 examples of Shawn Caroll's epic book, the big picture.

1 the universe is expanding
 2 humans and chimpanzees share a common anscestor,
3 we should live happier and longer lives.
The first 2 statements are rooted in science. We use impericism, resoning and observation to explain them.



The last statement is not rooted in science. Science doesn't involve doing experiments to decide if people should lead happier, longer lives. Science just observes the world and it doesn't say whether  something is right or wrong. Another way of looking at this is through evolution. Evolution is an incredible process based on millions of years of change, adaptation, and impulses. It just follows the laws of nature, but can't explain how to live your life.
You have the power to change your life. You have the power to care about others, and you have the power life love laugh, babe, and that is incredible. After you do inevitably die, you live on in the memories of others for the time being.

And then, you'll be forgotten in the change and passing of life. There are this  any atoms in your body which insanely amazing but, these little guys will eventually stop being you.
And even though collectively they will no longer be you, it is comforting to know that they will remain on earth after you have left.

Once gone, even if the whole human race vanishes, the universe will still be here doing its thing, moving along according to the laws of nature. But sticking to right now, according to science, we are all sharing this universe, sharing the same laws of nature and sharing the same task of creating meaning to what is happening around us. It is estimated that you have around 3 billion heat beats in a life time, so it is up to you to make them count. So, some scientific reasons to not fear death is 1, we humans are meaning making machines, we can choose to not make death a dreadful thing, and choose to live a meaningful life.

you might feel insignificant, but there lies within you more neural cells than stars in our universe. eventually you will stop making ATP, but the fact that it ends, is what makes life so great. science can't explain everything, so it us to you to choose to live your life to your fullest. And 5, eventually your atoms will atoms will stop being you, but you were made of will likely carry on for eternity.
Science is a brilliant way to view the complexity of your life and help inform how you live it, while here, and thankfully, if you are still watching this, congratulations, you are alive, but again if there's one thing I can say about you right now, it is that you, yes you are going to die.
