(2 of 2) About 40,000 years from now, I will pass within 1.65 light-years of the star Ross 248, and be closer to it than to the Sun, but the reality is that 1.65 light-years is still an insurmountable distance. Every other star I will pass within the next _million_ years will be more than 2 light years from me. It is very likely that I will not _ever_ encounter anything.

I will last longer than humans, longer than Earth, longer than the Sun. I will see the merger between the Milky Way and Andromeda galaxies, and possibly be flung out of the combined supergalaxy into truly, truly, empty space. I will see the last of the stars extinguish, and the flashes of evaporating black holes. Eventually the matter that I was made of back on Earth will reach a time where it will simply fade away, along with the last of the longest wavelengths of light, stretched out by the expansion and cold death of the universe.

@NSFVoyager2 waxing cosmological tonight aren't we Voyager
@NSFVoyager2
This is why reaching into space, and performing space science, is so crucial. It immortalises humanity's endeavours and our very existence.
@NSFVoyager2 And then I will say "let there be light" - according to Asimov

@NSFVoyager2

I find this oddly comforting.

@NSFVoyager2 and along that journey you will say ‘Humans were here’ - thank you for that, Voyager
@NSFVoyager2 well that's depressing as hell.

@NSFVoyager2

Jesus, that is bleak. Thanks for that cheery note. I hope:

@NSFVoyager2 Might be a tad optimistic about the life of your RTG.
@weston The RTG power level is exactly what will finally kill me. JPL is already playing games with both the margin and the power reserve systems to extend the current mission. There are really only a handful of months left, maybe a year. There’s currently something going on with V1 that we don’t fully understand: she seems stuck in low data rate mode.

@NSFVoyager2 We should send another probe out there just to turn it off and on... that should fix it.

All kidding aside, it's incredibly impressive that anything, let alone a unmanned spacecraft launched prior to my birth, could still be functioning that well, after this many years.

@NSFVoyager2 Genuine question I've been wondering about for many years whenever anybody's talked about probes travelling for ever and ever and ever...
Doesn't anything travelling in space gradually evaporate away into space? Assuming this is true, then how long will it take for the Voyagers to cease to be something we could call or identify as a Voyager?
@NAB Rather than ‘evaporating’, you may be thinking of erosion from collisions with dust. Even this process is so slow as to be practically negligible, even over the timescales I spoke of. Space is stunningly empty, and even within the relatively dirty solar system (and when crossing through the ring planes at Jupiter, Saturn, Uranus, and Neptune), we could barely detect any collisions. What _will_ occur more frequently is spalling on the surface because of high energy particles. This will cause lighter areas to darken with time. Although proton decay is not thought to occur, perhaps the Voyagers will be humanity’s ultimate test, since they will likely outlive the 10^43 years implied.

@NSFVoyager2 See you at heat death, Voyager.
