Why do all things in the universe ultimately move towards death?
What does death truly represent?
Is it really the end of everything?
Please read carefully until the end, as this may bring you a whole new understanding. Death refers to the irreversible and permanent loss of the attributes that sustain existence within a life system, representing the end of a state of being.
Taking life on Earth as an example, a dog's lifespan is generally between 10 to 15 years, while humans live around 80 years. The Greenland Shark can live over 270 years, and even the so-called immortal Lighthouse Jellyfish has its moment of true death.
Death is not limited to living beings; it also applies to celestial bodies in the universe. In about 5 billion years, when the hydrogen inside the Sun is depleted and it can no longer undergo nuclear fusion to release energy, the Sun will begin to approach the end of its lifespan, eventually evolving into a barren White Dwarf.
Similarly, Earth has its own lifespan. As the Sun enters its final stages, its expanding outer layers will eventually consume Earth mercilessly.
From a microscopic perspective, everything in the universe is composed of elements, each radioactive element having its own half-life. For instance, Polonium-215 lasts only a fleeting 0.0018 seconds, while Uranium-238 can last an extensive 4.5 billion years.
In a certain sense, whether in the macrocosm of the universe or the microcosm of atomic structures, nearly everything has its own lifecycle. According to the Law of Conservation of Energy, the total amount of energy remains constant; it cannot be created from nothing or disappear into nothing but can only transform from one form to another.
According to the Entropy Increase Law, in a closed isolated system, the total amount of entropy will only increase and never decrease, and this process is irreversible. While these two concepts may seem contradictory, they actually complement each other.
Although the total amount of energy remains unchanged, its form and distribution will change over time, reflecting the effects of the Entropy Increase Law. This means that what we call death is merely a transformation from one form to another.
For example, from weighing less than 10 pounds at birth to now exceeding 100 pounds, where did all that extra material in your body come from?
How much of the material that makes up you now is the same as that which made up you ten years ago? And when you lose weight, where does that portion of material go?
The universe is similar; when the Sun becomes a White Dwarf, where does the material that once composed the Sun go?
In fact, death is not the end of all things. Everything in the world ultimately just transforms into another form; they never truly disappear, so how can there be annihilation?
Supernova
Two and a half million years ago, a Southern Ape was resting under a tree.
As the sun set, it witnessed a perplexing scene: in the starry night sky, a star began to shine brighter and brighter, even surpassing the moon.
Even during the day, it shone like the sun, and over the next few days, its brightness continued to increase, eventually exceeding that of the sun. It wasn't until months later that this star gradually dimmed and ultimately vanished into the vast sea of stars.
What this ancient ape saw was actually one of the most destructive events in the universe: a Supernova Explosion.
When a massive star reaches the end of its life, its internal fusion fuel will be exhausted. This causes the outer layers of the star to collapse under gravity and explode outward due to immense gravitational potential energy, forming a rapidly expanding sphere of hot light.
During this process, highly magnetized gas clouds act like a giant Particle accelerator, accelerating all charged particles to near light speed. This results in lethal high-energy electromagnetic radiation being emitted in all directions while illuminating the entire galaxy it resides in.
The energy released by the explosion can instantly obliterate all life within a 50-light-year radius. Although the destructive power of a Supernova Explosion depends on its distance from us, humans have witnessed several supernova explosions thousands of light-years away and remained unharmed.
However, if the Earth is only 100 light-years away from the explosion point, then after being bombarded by radiation for several decades, not only will the protective Ozone Layer be completely eroded, but the entire atmosphere will also become ionized, forming a continuously accumulating rain cloud.
When these clouds cover the entire Earth, a large amount of Sunlight will be reflected back into space, ultimately leading the entire planet into an Ice Age.
Moreover, researchers have discovered Radioactive Principles in Seabed Minerals, and this finding indirectly proves that shortly after the Southern Ape lay down, the Earth entered the terrifying Quaternary Ice Age due to a nearby Supernova Explosion.
