"Runaway Star: Earth's Billion-Year Salvation Revealed"
A new theoretical study suggests that in about a billion years, a chance encounter with a passing star could save Earth from the sun's expansion by tossing it into a cooler orbit or helping it break free from the solar system entirely. However, the chances of this happening are extremely slim. The study simulated how our solar system would behave if a star swept past it, and found that in some simulations, Earth was pushed into a farther, colder orbit or landed in the Oort cloud. In a few simulations, Earth was gravitationally lured away by the wandering star, potentially allowing for liquid water. However, the overall odds of this happening are just 1 in 35,000. The study suggests that instead of relying on a stellar savior, we should focus on finding our own solutions to modify Earth's orbit or block a fraction of the Sun's incoming energy.
