FTL Time Travel Future
The relativity of time isn’t just why we can’t go out into space and come back the same. It can actually be used as a tool to preserve someone traveling at faster-than-light speed or through a kind of wormhole. Someone who’s 25 in 2025 could leave on an FTL trip and come back still 25 but find Earth long gone. If the trip is planned right, they could skip ahead hundreds or even thousands of years and see what humanity became. Maybe people mastered life extension and stopped destroying themselves. Or maybe Earth’s just dead, and the traveler ends it there, or drifts out into space in case something else ever finds them.That’s basically time travel to the future. We don’t have FTL or wormholes yet, but they could be the simplest way to make it happen.
An AI could someday navigate and calculate everything once we figure out propulsion, power, and materials. Particle accelerators might even point us in the right direction.I imagine two possibilities: one where Earth’s thriving, built up with massive structures, proof we made it; the other where it’s burned out after nuclear war. The first one’s worth betting on. Living to see what humanity becomes sounds way better than traveling to dead planets. And if we ever change our biology enough to live on other worlds, that’s a bonus. I’d take that risk, even if it means coming back to nothing. Or maybe one day we just turn Earth itself into a ship using its core for power and fly it through space. Imagine that.
