Know the age of the earth, the way of science knows it & until the earth will survive
Many may not know that the official age of the earth is around 4.54 billion years. This figure has been set since the 1950s and remains until now apart from science.
So, how can scientists really determine the age of the earth, and how long the earth can survive before being destroyed
The initial theory of the age of the earth
Efforts to find out the age of the earth have been carried out for hundreds of years.
Ancient Greek philosopher Aristotle believes that time has no beginning or end, and the earth has existed in the past.
In ancient India, a religious scholar estimates that the earth is around 1.97 billion years. This estimate is based on the belief that the universe continues to explode, develop and collapse repeatedly.
In the Middle Ages, Christian theologians tried to calculate the age of the earth based on the interpretation of the Bible, and the results were between 5,471 and 7,519 years, according to the book Earth’s age By G. Brent DalryMple.
In the 18th and 19th centuries, scientists began to estimate based on the earth level, the accumulation of sediment and chemical changes in the ocean.
However, all of these approaches only provide a very different budget.
Radiometric Date Method Findings
Real progress arises when scientists introduce the radiometric method, which is the age -age calculation method using the decomposition rate of radioactive elements.
This element will change naturally from the original (parent isotope) to a stable form (child isotopes) over a certain period of time.
By measuring the ratio between the isotope of parents and children, scientists can accurately calculate the age of stones.
At the beginning of the 20th century, scientists like Boltwood began to start the use of this technique, and then perfected and used to study stones brought home through Apollo’s missions in the 1960s and 1970s.
This method not only helps calculate the age of the earth, but is also used to study other planets.
Important discovery by Clair Patterson
In 1953, a geochemical expert from the California Institute of Technology, Clair C. Patterson, used the Radiometric Meteorite method and several other space spaces that were believed to be formed from the same material disc.
Patterson estimates that the earth is around 4.5 billion years old, and that number remains the same today.
Although this discovery was considered important in the world of science, Patterson himself said, “No one cared at that time.
How long will the earth exist?
Now, the sun is the main source of energy for the earth. However, one day, the same sun will be the culprit of the destruction of this planet.
According to space expert, Dr. Ravi Kopparapu from NASA, Earth is expected to ‘disappear’ completely in about 4.5 billion years, when the sun turns into a giant red star and swallowing the earth.
However, before the earth is physically destroyed by the sun, it will not be suitable for early life.
In the next 1.3 billion years, the earth’s temperature will rise so high that the ocean will begin to boil and evaporate, followed by the loss of atmosphere, as well as the destruction of the earth by the gravity of the sun’s gravity.
Earlier threat: man -made climate change
Unfortunately, humans may not need to wait for billions of years to face destruction.
According to scientists, climate change as a result of human activity can cause human extinction and many other species in the following century.
One of the most dangerous threats is the temperature of wet bulb, high temperature and a combination of humidity. This condition causes the human body to no longer be able to cool itself through sweat.
At this temperature, humans can die even under the shade. Recent studies show that wet temperatures as high as 30 ° C to 35 ° C can be fatal.
Some areas on earth, such as the Middle East, have recorded wet temperatures above 32 ° C and are estimated to reach 35 ° C periodically at the end of this century.
This condition can cause people and animals to sweat “cooking” in their own bodies because of heat.
