The Tesseract collapsed, spitting Cooper back out into the solar system near Saturn. He had aged only a few years, but decades had passed on Earth. He was found, drifting in space. By the time he woke in a hospital on Cooper Station—a vast, cylindrical ark orbiting Saturn—he had missed everything. He was 124 years old. He learned that Murph had taken his data, solved the equation, and saved the remnants of humanity.
He was inside the Tesseract, a four-dimensional space constructed by hyper-advanced future humans—the "Bulk Beings." The walls of the Tesseract were the infinite moments of Murph’s bedroom.

Decades earlier, a mysterious wormhole—a tear in the fabric of space-time—had appeared near Saturn. No one knew who placed it, but it was an invitation.

The sky was a permanent, dusty brown, and the only thing growing faster than the blight was human desperation. We had stopped looking to the stars. We were farmers now, just trying to survive one more harvest.
