What do scientists think happens after death?

According to science, after death, the body undergoes a biological process of decay, starting with cells breaking down (autolysis) and bacteria taking over (putrefaction), causing stiffening (rigor mortis) then relaxation, and eventually decomposition into simpler matter, with the brain showing temporary activity after the heart stops. Consciousness as we know it ends, as it's tied to brain function, but some studies show brief bursts of organized brain activity (gamma waves) after clinical death, suggesting consciousness might fade gradually rather than instantly. 

What happens 30 minutes after death?

About 30 minutes after death, the body experiences pallor mortis (paleness due to blood draining), begins algor mortis (cooling), and livor mortis (blood settling) starts, while muscles relax, causing facial changes and sphincter release, as the heart stops and brain activity fades. This initial period involves rapid changes as circulation ceases, leading to skin paleness and the onset of other post-mortem processes like the gradual stiffening of rigor mortis and the slow decay by microbes.
