0:00.0	Long after the last star fades, physics keeps going.
0:05.0	The question is whether intelligence can go with it.
0:09.0	We don't often think about the far future in practical terms, not the next deadline or the length of a human lifetime,
0:18.0	or even the span of recorded history, but the deep future. The kind
0:22.7	measured not in years or millennia, but in trillions upon trillions of years. Future is so distant
0:29.2	that stars themselves become temporary features, and even atoms begin to look fragile.
0:35.0	Yet if intelligence can survive long enough, those futures matter.
0:39.4	This episode is about that question, not whether the universe ends, or whether thinking
0:44.2	means can persist as it does, whether civilizations can adapt not just a change, with the slow,
0:50.5	relentless erosion of structure, energy, and time itself. And, if they can, what that survival
0:57.0	actually looks like when it stretched across cosmic epochs. What you're about to watch is the
1:02.0	longest episode we've ever made. It's fully chapterized, designed to be watched in one sitting
1:07.1	or revisited in pieces. You may watch it in its entirety or skip familiar topics.
1:12.7	Whichever you pick, you may want to grab a drink and a snack, or several, and settle in.
1:18.6	We're going to be here for a while. And if you enjoy this kind of exploration,
1:23.4	please consider liking the video, subscribing to the channel, and supporting us if you can,
1:28.5	by joining the channel on YouTube or donating on Patreon or PayPal.
1:32.5	This project exists because enough people decided that deep, careful discussions of the fall of future were worth sustaining.
1:39.6	Now, a quick note about what this episode is, and what it is not.
1:43.6	This is not every episode ever made
1:45.9	about the end of the universe, stitched together end-to-end. That would have run closer to 10 hours
1:50.6	and involved a lot of repetition, since some ideas need to be reintroduced each time they appear.
