For millions of years, Earth has been the only known planet teeming with life, but we all know it won't last forever. So, when will it all come to an end? What does science say about the inevitable? New studies from the U.S. are offering chilling predictions about how and when our planet might face its ultimate demise. Are you ready to uncover the truth? Let’s dive into the unsettling forecasts and shocking theories about Earth’s future!
Our planet has existed for millions of years, while human history is measured in mere thousands. While we see signs of humanity's potential downfall, what about Earth? There are various opinions and beliefs on this topic. It is impossible to know for sure how the end of Earth will come. All we have are our beliefs and certain claims.
The Sun is said to be currently in the middle of its fusion lifespan. At about 5 billion years old, the Sun, like us, is growing and aging. As it ages, certain characteristics begin to change.
The Sun will continue its process of turning hydrogen into helium, and the proportions in its core will gradually change. Over time, the Sun will become more efficient at fusing hydrogen. Its brightness will increase, and this increase will have noticeable effects on Earth. The carbon, nitrogen, and phosphorus cycles will be disrupted, and the amount of carbon dioxide will decrease.
The disruption of plant life cycles will reduce the amount of oxygen needed by animals and humans. The number of animals that rely on plants as a source of life will decrease. Even if humanity finds a way to grow plants, the amount of oxygen produced by plants will still decrease. Eventually, only microbes will survive on Earth!
By then, unless humanity brings about the end of Earth itself, the Sun, which provides warmth to the planet, will ultimately bring about its end.
