There’s a short essay on the Internet about why one would want to have a physicist speak at one’s funeral, by Aaron Freeman. I find it comforting to a degree. Yet today I also found Anonymous’ response to it that resonated. We only have what is present in front of us, yet somehow the unboundedness and connection suggested here brings me comfort.
“If I had a physicist speak at my funeral, I would hope that he would talk about a lot more than the conservation of energy. I don’t particularly care about what happens to my energy.
If I am lucky, he will speak about relativity. My family will probably have the mistaken intuition that only things in the present are truly real. Teach them about spacetime. They need to know that time and space are connected – that me being in the past is just like me being far away. The difference is that we will only have one way communication. Even if they will no longer be able talk to me, I will still talk to them through memories.
If I am not so lucky, he will speak about quantum mechanics. If I die young, my family will be grieving over the potential future I have lost. Teach them about many worlds. They need to know that our world is constantly splitting – that just before I died, the world split off a different future in which I am still alive. There is another world, just as real as our own, in which I survive. This world will even interact with our own in very tiny ways.
I want a physicist to speak at my funeral. I want everyone to understand that my continued existence is way more verifiable than a religious afterlife and way more substantial than a simple conservation of energy.”
