> It's 100% physically plausible, using technology we have today, to make humanity star-faring. That kind of claim needs an actual source, because it's not. The distances are so many orders of magnitude too high for any of today's technologies, making this a pure daydream. The best we could plausibly do is travel within Sol, and that's not starfaring. It would have to be a multi generational journey in which any refueling/restocking is impossible and any slip up would cause a full wipeout. Starfaring is far beyond us... and that's unlikely to ever change for humans with a biological body.
