No, humans will not survive for 1 billion years according to current scientific understanding.
Human Extinction Timeline
While it's impossible to predict the exact future with certainty, the most optimistic estimates suggest that humans may last another billion years. However, this timeline is tied to the life cycle of our sun.
The Sun's Role in Human Extinction
- The primary reason for our eventual extinction, as per the reference, is the expanding envelope of the sun.
- As the sun ages, it will swell outward.
- This expansion will cause the planet to heat up significantly.
- The Earth's temperature will eventually reach a level similar to Venus, making it uninhabitable for human life.
| Timeframe | Event |
|---|---|
| Next Billion Years | Possible lifespan of humans (optimistic) |
| Eventually | Human Extinction |
Therefore, while a billion years seems like a long time, the natural evolution of our sun poses a significant threat to human survival on Earth. The information from the reference indicates that human extinction is inevitable due to the sun's lifecycle, even within this optimistic timeframe.
