I liked the character's from Project Hail Mary perspective. The fact that we experience less time the closer we are to the speed of light is almost like an invitation to explore the stars.

Another things that gets me is the time experienced by black holes. We would think of the black hole at the center of the galaxy as some enduring, permanent thing, but with so much gravity, from the black hole's perspective it may only exist for a fraction of a second.

I don't fully understand how the science and theory works around all that ... all I understand is that it is so unbelievably far away that in order to cross any of those distances or even think about crossing those distances, it begins to break our normal understanding of speed, distances and time.
