Review
If we think of the earth as a living thing, it is 4.5 billion years old, and we all want to know, is the current earth in its youth, middle age, or old age?
Some scientists have pointed out that the temperature of the earth's inner core is falling at an accelerated rate, and the earth's magnetic field is also disappearing, which seems to be very far away from us, but it is closely related to the future fate of mankind.
The Earth's inner core is cooling at an accelerated rate
Whether the Earth will become another Mercury or Mars, something very bad is happening, much sooner than humans expected. Scientists estimate that the Earth's core is cooling at a rate of one degree Celsius per year, and it is expected that in 50,000 years, our planet will become very cold.
Volcanoes, earthquakes, and geothermal activity on the Earth's surface are thought to indicate that the Earth's interior is in a state of activity, high temperature, and high energy. As everyone knows, this is a manifestation of the heat released by the earth's inner core, and the temperature of the earth's interior continues to drop, and the energy is constantly disappearing.
As we all know, the heat flow and seismic measurements of the earth show that the earth is composed of three parts: the core, the mantle and the crust, and the temperature of the core is close to 6000 degrees Celsius, which is half the temperature of the surface of the sun, but the temperature of the core is rapidly being transmitted to the crust.
Scientists published an article in the journal Earth and Planetary Science Letters, about the study of "Bridgemanite" between the Earth's core and mantle and how "Bridge Manganese" dissipates heat, and found that the thermal conductivity of the Earth's core is about 1.5 times higher than the researchers predicted. If the "Bridgemanite" is transformed into a mineral called post-perovskite, the heat is conducted more rapidly.
Elemental decay consumes life on Earth
For many people, lifespan is only for living organisms, like a stone, will a pile of scrap metal have a lifespan? Of course there is.
When we calculate the age of the earth, how do we know that the earth has existed for about 4.5 billion years, the principle is simple, find the oldest rock on the earth, plus the half-life of detecting radioactive elements in the rock, for example, the half-life of uranium-238 is 4.468 billion years, and look at the degree of decay, we can roughly estimate the age of the earth. So, even without earthquakes and volcanoes, the Earth is quietly releasing energy in other ways, consuming its own life.
Indicators of life on Earth, declining magnetic field
Another worrying thing is that the Earth's magnetic field is declining, with scientists showing that it has fallen by 9% in the past 200 years.
The inner core of Mars and the Moon is also hot, but it is no longer able to support a molten inner core, let alone flow! If the Earth's core cools faster, the engine that generates the magnetic field could shut down forever.
The Earth has lost the umbrella of life
Without the umbrella of the magnetic field, the Earth will be photographable, and it will be like a monster without clothes, running wild in space.
- Charged particles will penetrate the atmosphere and sweep the ground
All satellites and airplanes in space and air will fall due to radiation, all power systems on the earth will be paralyzed, life will be difficult to walk on the earth, and slowly, the ground will no longer be suitable for the existence of life forms.
- A large number of charged particles bombard the upper atmosphere
The Earth's atmosphere will gradually escape, the surface atmospheric pressure will weaken or even disappear, and the sea water will boil at a low temperature but without pressure, and escape into space. The surface began to get extremely dry, and finally there was no wind or sound.
Human responses
No matter how the universe changes, human beings will find ways to continue their civilization. In this extreme case, humanity may have two approaches.
- Go deep underground
It is estimated that at that time, humans were already able to control nuclear fusion as they wanted, and they could use various combinations of elements to generate water, air, and food, store large amounts of resources in advance, or use interstellar travel to other planets to collect resources. Humans have since become real underground creatures.
- Escape from Earth
Escaping the Earth is something that humans have always wanted to do, and now the moon and Mars are all in progress. At that time, Mars could become a second home for mankind. The environment of Mars and the environment of Earth cannot be compared with the estimation of which is better or worse.
epilogue
Of course, the earth's core is cooling at a rate of one degree Celsius per year, which is expected to lead to downtime in 50,000 years, which has been questioned by mainstream academics, and the disappearance of the earth's kinetic energy is also a matter of 100 million years later, and the earth's climate, geological environment and geomagnetism, the heat dissipation of the earth's core, has not been actually scientifically proven, so human beings do not have to worry.
The universe is constantly changing, the earth is constantly changing, and human intelligence is constantly changing. Only when human beings look at the problems facing the earth from a cosmological perspective can it be possible to create the miracle of life.
