The Sun is the primary energy source that makes life on Earth possible, yet its role is often taken for granted. Even small changes in solar behaviour can have profound consequences for climate, ecosystems, and planetary stability.
Sun Scenarios explores scientifically grounded “what if” questions focused on the Sun’s influence on Earth and the solar system. These articles examine realistic possibilities using established physics, astronomy, and climate science, avoiding speculation that drifts into science fiction.
Each scenario is designed to explain cause and effect clearly, tracing how changes in solar output, position, or behaviour would ripple through Earth’s atmosphere, oceans, and long-term habitability.
If the sun went out for 24 hours, Earth would experience sudden darkness, rapid cooling, and global disruption. For most of human history, the Sun has been the most reliable presence in our lives. It rises, it sets, and it powers nearly every system on Earth. But imagine a scenario where that reliability vanishes. No … Read more
