Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Why does thinking about this make me a bit sad?
If we take a moment to anthropomorphize Voyager here - It kinda is. Think of the pure vastness of space. Remember that all of the planets in our Solar System can fit between the Earth and our own Moon with a little space to spare.
Look up to the sky, point in any direction and (with the magical ability to fly up and through space) go in that direction without changing course, and there is an almost 100% guarantee you will never run into anything. Sure you may see things go by as you travel, but its just..never ending travel, fast as shit, through endless space until you just..stop and die.
Voyager's just gonna keep going, and going...and going. It's material will eventually break down I assume, due to exposure, and perhaps fall to pieces, but...it'll keep going.
Is that from Hitchhiker's Guide to the Galaxy by Douglas Adams?
exposure to what? it will keep floating forever.
I would suspect at some point it will come into contact with other matter but yea... That could take a very, very long time.
sure, that could happen, although extremely unlikely. but never say never I guess!
Given an infinite amount of time, I would say the chance are not just likely, but certainly 100% chance of happening
Not neccasarily. You have to remember that space is expanding. That means that eventually the probes would undergo the big rip where they are torn apart. Prior to that however, they would be so far from anything that it would be impossible for them to interact with anything.
Definitely, it will happen at some point. Probably not for an unfathomably long amount of time, however.
Maybe a fucking black hole will suck it even.
It would have to be on a direct collision course, which would still lead to those stats that would be represented in scientific notation due to how unlikely it is to occur.
They will float until we intercept them in a thousand years, or their atoms begin to decompose
Bold of you to assume we'll be around in 1,000 years
Hey you leave my mom out of this.
radiation in space is strong
micrometeorites
Space exposure. I'm not what anyone would typically classify as "smart" by any stretch but I have to imagine being out traveling in interstellar space for (eventually) centuries will end up in some kind of eventual damage, be it either from idk fuck ass Space Radiation™, or micro asteroid impacts, or anything else.
The cool thing about Voyager is that it has a record of information about Earth, etched in gold, with instructions on how to read the data it contains back.
Even once it powers down, it's still on a mission. If millions of years from now intelligent alien life ever encounters it, they will know who we were and that we existed.
It's our handprint on the cosmic wall.

They will likely be the last evidence that the human race ever existed.
In 2-3 billion years the sun will leave the main sequence steady state it has been in. This will end in it turning into a red giant, and engulfing earth and destroying all record we existed.
Meanwhile, the journey of Voyager 1 and 2 will have only just begun. They will continue moving through the expanding universe for at least 3,000,000 Billion years.
Wouldn’t friction (however little in deep outer space) eventually decay the crafts way before Earth is engulfed by the Sun?
Interspace is empty on a level that is hard to imagine.
There are 2.652×10^25 molecules in one m^3 of air.
That is 26520000000000000000000000.
In intellar space?
The is 1.
IE: the probe would hit more atoms in one second on earth moving at 1 m/s than it would travelling the entire age of the universe so far through interstellar space.
Even the space between the planets is thick with matter by comparison.
That is indeed mind boggling. Thank you for sharing this with me. I did not realize it is that thin out there!
265.2 septillion, if I'm not mistaken. Mind-boggling!
I don't think this comparison is really valid. If you are going through the molecules of air at the speed voyager is currently going it would vaporize. If you're comparing it to more terrestrial speeds, It also ignores the amount of energy imparted by that 1 atom due to the high velocity. The high velocity also means it encounters those singular atoms and a higher rate.
If we never send a spaceprobe ever again that is
If we are lucky the earth might survive after the sun becomes a red giant. As the sun expands because its gravity is weakening which means the hold on earth will be weaker and the earth will move away from the sun. Hopefully the speed we move away is equal to or faster than the suns expansion.
It'll be back as Vger after a couple hundred years and try to kill us, no biggie.
Well the last Voyager came back from deep space with a sexy borg lady, so I for one look forward to their return.
It'll miss us by 2 degrees it seems.
