 How many years will the Earth survive?

It's difficult to predict exactly how long the Earth will survive because it depends on a number of factors, including the ongoing processes that shape the planet and the potential future actions of humanity. However, the Earth has existed for around 4.5 billion years, and it is expected to continue to exist for several billion more years.

One of the key factors that will affect the longevity of the Earth is the sun's evolution. In about 5 billion years, the sun is expected to run out of hydrogen fuel in its core, and it will begin to expand and cool. This process, known as the "red giant phase," will cause the sun to expand and grow so large that it will likely swallow the Earth.

Another important factor to consider is the potential for human-induced climate change to have a significant impact on the planet. If emissions of greenhouse gases continue to rise, it could lead to increasingly severe global warming, which could have devastating effects on the environment and human civilization.

It's also important to consider the impact of space collision as our solar system is constantly under threat of collision from comets, asteroids and space debris. The collision of these space objects with earth has the potential to end human civilization or even wipe out the human species.

To sum up, while it is impossible to predict exactly how long the Earth will survive, it is expected to continue to exist for several billion more years, but its future will be determined by both natural and human factors.
