    In theory yes… but the oldest frozen specimen of humans we’ve found is only a few thousand years old. We don’t even know if long term cryogenic reanimation is possible.

    Assuming the ship travels at 10x our current capabilities we’re still looking at ~8,000 years to reach our closest stellar neighbour at only 5 lightyears away.

        We’ll still run into the same assumption/problem; shelf life.

        Consider how memories work. Every time you remember something, your brain alters that memory slightly. Even looking at how the brain parses the data through several cortex (visual etc) implies that consciousness is potentially inseparable from the components of the brain. In this video about Cockatoo intelligence they speculate that birds brain anatomy causes them to think in ways that seem limited to us.

        Basically we don’t even know if its possible to preserve human consciousness for that long. Similar to cryogenics we have to question if reanimation is even fundamentally possible after centuries.

          Then take the solar system with us. Strap a solar thruster to the sun, and off EVERYTHING goes. It’s a byproduct of figuring out starlifting, and that buys us all the time in the universe, at least till we run out of Hydrogen and Helium to shove into the sun as fuel, but there’s literally entire solar systems worth of that stuff hanging around in deep space. Like 72 solar masses per cubic light year of “empty” space.
