“More important is that our compression of subjective time can be exponential, while our ability to escape from ever-broader swaths of destruction is limited by lightspeed.”
Eventually, compression in subjective time stops, while expansion continues.
You’re right. It still has a large impact, though. Even if we get only 3 more doublings, it reduces the time available by a factor of 8.
The nearest other galaxy is 2 million light years away. If we get 6 doublings, that’s 128 million subjective light years. That’s a worrisome amount.
The nearest other star is 4.24 light years away. If we get 20 doublings, that’s over 4 million subjective light years away. Also a worrisome amount.
The observation bears on this statement:
“More important is that our compression of subjective time can be exponential, while our ability to escape from ever-broader swaths of destruction is limited by lightspeed.”
Eventually, compression in subjective time stops, while expansion continues.
Yes, that’s right. If you can survive long enough to get to that point.
