Basically, you know how a dam produces energy? Turbines harness the natural propulsion of water flowing downward via gravity to generate electricity. To be clear, that's more or less all I understand about hydroelectric power. Gravity pulls water down, so if you stick a turbine in its path, the water spins it around and somehow makes energy.

The Goettreider Engine does that with the planet. You know that the Earth spins on its axis and also revolves around the Sun, while the Sun itself moves endlessly through the solar system. Like water through a turbine, the Goettreider Engine harnesses the constant rotation of the planet to create boundless energy. It has something to do with magnetism and gravity and . . . honestly, I don't know-any more than I genuinely understand an alkaline battery or a combustion engine or an incandescent light bulb. They just work.

So does the Goettreider Engine. It just works.

Or it did. Before, you know, me.

I am not a genius. If you've read this far, you're already aware of that fact.

But my father is a legitimate full-blown genius of the highest order. After finishing his third PhD, Victor Barren spent a few crucial years working in long-range teleportation before founding his own lab to pursue his specific niche field-time travel.

Even where I come from, time travel was considered more or less impossible. Not because of time, actually, but because of space.

Here's why every time-travel movie you've ever seen is total bullshit: because the Earth moves.

You know this. Plus I mentioned it last chapter. The Earth spins all the way around once a day, revolves around the Sun once a year, while the Sun is on its own cosmic route through the solar system, which is itself hurtling through a galaxy that's wandering an epic path through the universe.

The ground under you is moving, really fast. Along the equator, the Earth rotates at over 1,000 miles per hour, twenty-four hours a day, while orbiting the Sun at a little over 67,000 miles per hour. That's 1,600,000 miles per day. Meanwhile our solar system is in motion relative to the Milky Way galaxy at more than 1,300,000 miles per hour, covering just shy of 32,000,000 miles per day. And so on.

If you were to travel back in time to yesterday, the Earth would be in a different place in space. Even if you travel back in time one second, the Earth below your feet can move nearly half a kilometer. In one second.

The reason every movie about time travel is nonsense is that the Earth moves, constantly, always. You travel back one day, you don't end up in the same location-you end up in the gaping vacuum of outer space.

Marty McFly didn't appear thirty years earlier in his hometown of Hill Valley, California. His tricked-out DeLorean materialized in the endless empty blackness of the cosmos with the Earth approximately 350,000,000,000 miles away. Assuming he didn't immediately lose consciousness from the lack of oxygen, the absence of air pressure would cause all the fluids in his body to bubble, partially evaporate, and freeze. He would be dead in less than a minute.

The Terminator would probably survive in space because it's an unstoppable robot killing machine, but traveling from 2029 to 1984 would've given Sarah Connor a 525,000,000,000-mile head start.

Time travel doesn't just require traveling back in time. It also requires traveling back to a pinpoint-specific location in space. Otherwise, just like with regular old everyday teleportation, you could end up stuck inside something.

Think about where you're sitting right now. Let's say on an olive-green couch. A white ceramic bowl of fake green pears and real brown pinecones propped next to your feet on the teak coffee table. A brushed-steel floor lamp glows over your shoulder. A coarse rug over reclaimed barn-board elm floors that cost too much but look pretty great . . .
