Part 4/11:
One of the most profound concerns is maintaining sophisticated technology over unfathomably long durations, potentially trillions of years. Current technology struggles to last above a few decades, so envisioning machinery that can endure for such massive timelines appears daunting. However, gravitational time dilation near black holes could provide a unique opportunity to significantly slow down decay processes, allowing civilizations to experiment over cosmic timescales to create lasting components.
