He died right.
Astrophysicist Neil deGrasse Tyson captivated listeners on his podcast, Star Talk, as he discussed the transformation our bodies undergo after death.
“When you die, you don’t disappear; you transform,” he noted in the video, which has garnered over 1.2 million views.
Tyson elaborated that the way one’s body is handled postmortem plays a crucial role in this transformation.
He pointed out that in today’s world, there are primarily two choices: burial or cremation. Personally, he leans toward burial, believing it allows for the “energy” to be recycled.
“Your molecules come from a lifetime of consuming food, exercising, and developing various tissues,” Tyson explained. “Even after death, those molecules still hold energy.”
“If I get buried and decompose, that energy gets absorbed by microorganisms that consume my body, just as I consumed plants and animals in life. This process essentially allows me to give back to the earth.”
He mentioned that if one were cremated, the energy would be released as heat and could ultimately travel through space. “If they had been cremated four years ago, they would have ended up in the nearest star system, Alpha Centauri,” he remarked, suggesting that, in a sense, we remain part of the universe, only in a different form.
Tyson highlighted that as bacteria, fungi, and other microorganisms break down body components, it’s a continuation of life.
Though natural burial may seem more environmentally friendly, Tyson insisted that cremation isn’t without merit. “When a body is burned, the energy transforms into heat, which then radiates into space at the speed of light,” he demonstrated with a visual of flames.
A silver lining to this cosmic journey is that bereaved loved ones can trace where the energy might have gone in the galaxy. Tyson’s discussion on energy transfer aligns with the first law of thermodynamics, which tells us that matter is neither created nor destroyed but changes form.
Many viewers were touched by Tyson’s insights, with one person describing it as “the most beautiful look at death.” Another commenter stated, “This is so profound,” while yet another reflected, “Back to the stars.”
One individual shared a personal loss, saying, “I had my son cremated almost four years ago. So happy to hear that.”
Yet, the topic stirred debate over the merits of burial versus cremation. One viewer expressed that “running to Alpha Centauri at the speed of light sounds much more romantic than being eaten by bugs.” Conversely, another pointed out that being decomposed by insects and microbes recycles the particles into the earth, contributing to ongoing life.
Tyson isn’t the only figure to delve deeply into these themes. In a piece titled “What happens to atoms when they die?”, engineer Irvin Ash discussed how after cremation, ashes return to the soil, feeding plants that may eventually nourish animals, including humans, thus completing the cycle of life.
In the end, as Ash puts it, “Eventually, a small portion of you will become your great-grandchildren’s morning cereal or hamburger.”
