You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the about the first law of thermodynamics; that no energy gets created in the universe, AND NONE IS DESTROYED.
You want your mother to know that all your energy, every vibration, every Btu of heat, every wave of every particle that was her beloved child remains with her in this world. You want the physicist to tell your weeping father that amid the energy of the cosmos, you gave as good as you got.
And at one point you'd hope that the physicist would step down from the pulpit and walk to your brokenhearted spouse there in the pew and tell him/her that all the photons that ever bounced off your face, all the particles whose paths were interrupted by your smile, by the touch of your hair, hundreds of trillions of particles, have raced off like children, their ways forever changed by you. And as your widow rocks in the arms of a loving family, may the physicist let her know that all the photons that bounced from you were gathered in the particle detectors that are her eyes, that those photons created within her constellations of electromagnetically charged neurons whose energy WILL GO ON FOREVER.
You can hope 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. -Aaron Freeman
Transitioning from a Christian to pantheist you start to wonder: OK what happens when I die? Is that it for me? And you feel fear everyday as you become older and older and your realize that your days are numbered. But when I read this it gave me comfort. It makes me feel at peace to know that I have been around since the beginning of the universe. I am the universe. I am you. We were stars. Wow, its so amazing this Universe that we're apart of.
