Predicting the exact timeline of the formation of the next supercontinent is a challenging task as it depends on a variety of geological processes and factors that are difficult to accurately predict. Supercontinent cycles occur over hundreds of millions of years, and the formation of the next supercontinent is likely to be far into the future.
As for the survival of humans until that time, it's challenging to make precise predictions about such long-term scenarios. The survival and longevity of the human species depend on a multitude of factors, including technological advancements, environmental changes, and our ability to adapt to various challenges.
It's important to note that the Earth's climate and geological conditions can undergo significant changes over long periods. While the Sun will continue to age and become hotter and brighter, the Earth's climate can be influenced by other factors, such as volcanic activity, ocean currents, and greenhouse gas concentrations.
Human survival in the long term will depend on our ability to address various challenges, including climate change, resource management, technological progress, potential cosmic events, and social and political stability. Predicting the outcome of all these factors over such extended time frames is extremely complex and uncertain.
As we look to the future, it's essential to continue promoting sustainable practices, scientific advancements, and global cooperation to increase the likelihood of our long-term survival as a species, whether it's until the formation of the next supercontinent or beyond.
