During this expansion, the Sun's radius will grow so large that it will likely engulf the orbits of Mercury and Venus, and possibly even reach the Earth's current position, rendering the planet uninhabitable long before physical contact. The core contracts under gravity, heats up, and begins to fuse helium into heavier elements like carbon and oxygen.
When Sun Dies Final Stages Human Impact
While the specific timeline is fixed, the material that constitutes our world has a history that predates the Sun and a future that will outlast it. The total process from the start of the red giant phase to the cooling of the white dwarf will take tens of billions of years.
This is a period of equilibrium where the immense gravitational pressure at the core is balanced by the outward pressure from nuclear fusion. The Sun's death is a quiet, lingering process rather than a violent explosion, a testament to the different scales of time that govern stellar evolution versus human lifespans.

After this ejection, the core itself will collapse under its own gravity, but not enough to create a supernova. Understanding its lifecycle requires looking beyond the immediate present to the distant future, a journey that spans billions of years.
