Neil deGrasse Tyson discusses the scientific process of decomposition and energy release after death, explaining how the body's energy is either absorbed by microbes or released into space through cremation, based on the laws of thermodynamics.
Explaining the science of what happens post-death, writer and podcast host Neil deGrasse Tyson revealed how the human body breaks down and is consumed by microbes and bacteria, which feeds on a person's chemical energy left behind.
Mr Tyson noted that a person's body is still filled with energy mainly from the food they digested over years, even after the heart and brain stop functioning. It is then said to be released either by cremation, which sees a person's remaining energy converted to heat after the body is burned, and then travels to outer space.
Britain 'can't return to status quo after Iran war shocks,' Starmer says as he battles for premiershipThis allows the Earth's microscopic organisms to absorb all remaining energy in the continuous cycle of renewal between humans and nature, which is the choice of Mr Tyson. He said on his StarTalk podcast: "In death, those molecules still contain energy.
If I'm buried and I decompose, all that energy gets absorbed by microbes, by flora and fauna dining upon my body the way I have dined upon flora and fauna my whole life. However, he added that it didn't mean those cremated were wasting their energy, and said their final journey would have more far-reaching consequences, as heat produced by cremating a body does not stay on Earth.
Tyson said loved ones of somebody cremated could keep a timeline of where their radiant energy had traveled to in the Milky Way. After a person is cremated, Mr Tyson claimed their loved ones could actually keep a timeline of where their energy had flown to in the Milky Way. He said: "If they were cremated four years ago, they would have reached the nearest star system, Alpha Centauri.
His theory is built upon the first law of thermodynamics, which states that matter cannot be created nor destroyed — it can only change from one form to another.
