About this book

What if the force that holds us to Earth could carry us toward Jupiter and Saturn instead?

In John Jacob Astor’s A Journey in Other Worlds, the year is 2000, and engineers reshape Earth. Three friends look beyond it. Thoughtful Ayrault, determined Colonel Bearwarden, and the scholarly Dr. Cortlandt set out in a craft powered by apergy, an imagined force that works against gravity.

Their voyage takes them to Jupiter and Saturn, pictured through the astronomy of Astor’s day. Adventure gives way to patient explanations of gravity, heat, light, and planetary life. Alongside these questions, the novel explores science, faith, and the soul, imagining what might lie beyond death rather than stopping at the limits of the visible world.

What you’ll discover

  • Earth remade by engineers Step into a future where technology shapes the world the travelers prepare to leave.
  • A force against gravity Follow the possibilities of apergy, Astor’s imagined means of pushing a craft away from planets.
  • Giant planets imagined alive Visit Jupiter and Saturn as Astor pictures them through the science of his time.
  • Three minds in motion Share Ayrault’s watchful curiosity, Bearwarden’s determination, and Cortlandt’s urge to explain what they encounter.
  • Questions beyond the planets Explore a hopeful, sometimes strange vision of the soul alongside the voyage through space.

A Journey in Other Worlds by John Jacob Astor, the cover

From the 15-minute summary · Key idea 1 of 6

A future Earth reshaped by engineers

The story opens in the year 2000, and the world it shows is far from the one Astor knew. Technology has grown into a power that people take for granted. Electricity does much of the work, and large engineering projects have changed the planet itself. The book gives a good deal of space to this setting before anyone leaves the ground.
