The Haunting Truth About How Long the Solar System Will Hold Together

How long will the celestial clockwork of our Solar System hold together? For centuries, stargazers and mathematicians from Isaac Newton to Henri Poincaré wondered whether the quiet dance of the planets is an eternal machine or a delicate balance destined to drift apart. Tonight, we journey through the deep mathematics of orbital chaos, Einstein's invisible relativistic shield around Mercury, and supercomputer simulations tracking billions of years into the future. Discover why a tiny millimeter of uncertainty sets a horizon of predictability, and how our cosmic sanctuary remains secure for eons to come. Sleep well.
