[QUOTE=laserguided;38697087]Is it even possible for it to come to a stop? Being interstellar space and assuming it hits nothing.[/QUOTE] After some brief research, both Voyager1 and Voyager2 should theoretically keep going indefinitely unless they hit something. [quote]In about 40,000 years, Voyager 1 will drift within 1.6 light years (9.3 trillion miles) of AC+79 3888, a star in the constellation of Camelopardalis. In some 296,000 years, Voyager 2 will pass 4.3 light years (25 trillion miles) from Sirius, the brightest star in the sky . The Voyagers are destined—perhaps eternally—to wander the Milky Way.[/quote]
[QUOTE=laserguided;38697087]Is it even possible for it to come to a stop? Being interstellar space and assuming it hits nothing.[/QUOTE] Cosmic drag will eventually stop it.
I wish they made another voyager with modern technology, so it could last longer and then blast it off to space as well :v:
[QUOTE=MIPS;38697162]Cosmic drag will eventually stop it.[/QUOTE] Google is failing me on this one, so maybe you can explain, since I've never heard of it. What is 'cosmic drag' in a nutshell? Is it basically suggesting that tiny particles will eventually provide enough resistance to bring a moving object to a complete stop?

The probe will hit scattered hydrogen atoms, micrometeors, cosmic dust, etc.
There's something beautifully romantic about the voyages and trips of our spacecrafts. If by chance the human race doesn't make it, this may be the sole vestige of our civilization that makes it somewhere distant in the universe, causing a puzzle of origin to some young species with a scientific mind.
[QUOTE=Forumaster;38697457]Yes. Even in space, it's not a perfect vacuum. The probe will hit scattered hydrogen atoms, micrometeors, cosmic dust, etc.[/QUOTE] Not enough to significantly affect the speed of the spacecraft in interstellar space.
I bet it's lonely out in space, on such a timeless flight.

[QUOTE=OvB;38697524]Imagine if we found some other species version of Voyager.[/QUOTE] What if our Voyager and the alien equivalent collide at the same speed and are equal mass, and then they stop and nobody ever finds them?
[QUOTE=MIPS;38697162]Cosmic drag will eventually stop it.[/QUOTE] I'd think weak magnetic fields and/or electrical fields from nearby objects or gravity would stop it first (what even is cosmic drag)
[QUOTE=Repulsion;38696276]I think one of the more amazing parts of this is that since space is so vast this actually happened quite a while ago; we've just barely received the signals, no?[/QUOTE] Did you even read? [QUOTE=OP] The signal from Voyager 1 takes approximately 17 hours to travel to Earth.[/QUOTE] [editline]3rd December 2012[/editline] Damn it.
Some day I'm hoping that we'll launch another probe that can travel faster and have a more indefinite power source. It'll be a sad day when we lose communication with it
[QUOTE=Disseminate;38697567]I'd think weak magnetic fields and/or electrical fields from nearby objects or gravity would stop it first (what even is cosmic drag)[/QUOTE] A term that was coined just now. Edit: In fact an effect that was invented just now.
[QUOTE=JeanLuc761;38696490]It's expected to last until 2025.[/QUOTE] Take note cell phone companies.
[QUOTE=lockdown6;38697998]i can't even tell what it represents, how are aliens supposed to understand it?[/QUOTE] Assuming that advanced space-faring civilizations do exist, they have to have the basic language of computers which is basically 1's and 0's. The disk is broken down in the most simplest form of binary codes which is just dots and dashes and it gambles on the hopes that the Alien race that we may encounter may be benevolent and uses vision to read the instructions.
[QUOTE=JeanLuc761;38696931]And it's this pretty thing right here. [t]http://upload.wikimedia.org/wikipedia/commons/thumb/b/bd/Voyager_Golden_Record_fx.png/598px-Voyager_Golden_Record_fx.png[/t] I'm somewhat surprised they included Earth's location on the disc. Here's hoping whatever intelligent life out there is not looking to subjugate.[/QUOTE] We were a lot more optimistic back then when it was launched. I think we seriously should cut any and all attempt at making contact with anyone until we have colonized Sol and have some capability to defend ourselves. Because I doubt any race would be so nice to suddenly give us technologies the moment they meet us.

Why are the aliens necessarily going to be as immature as we are as a species and kill for next to no reason? For all we know they have a much greater respect for life (perhaps after realising how thinly spread it is through the cosmos) and thus they have nothing but benevolent intentions. If ANYBODY was the instigator of an interstellar war between humanity and an alien species I'd imagine without a shadow of a doubt in my mind that it'd be us.

There is no reason for there to be some form of higher interstellar order, most likely it's just a battle for survival with the surviving species being those who were either isolationist or the aggressors.

Misread title as "Finds new Religion"

[QUOTE]Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet."[2] [B]Thus the record is best seen as a time capsule or a symbolic statement more than a serious attempt to communicate with extraterrestrial life.[/B][/QUOTE] Anyway. Make a moon base, make a steel reinforced concrete sphere (maybe half one so the other half can act as a dish) with enough awesome stuff to act like voyager1/2 then launch it. Space dust and what not will take so much longer to damage it.
[quote][img]http://images.sciencedaily.com/2012/12/121203154500.jpg[/img] ================================================== ========== Voyager 1 Explores the 'Magnetic Highway': This still image shows NASA's Voyager 1 spacecraft exploring a new region in our solar system called the "magnetic highway." In this region, the sun's magnetic field lines are connected to interstellar magnetic field lines, allowing particles from inside the heliosphere to zip away and particles from interstellar space to zoom in.

If they've reached the fucking space-faring age, they're smarter than to be dumb and paranoid about everybody they meet, and have by now found a form of government and society that doesn't include blowing everybody else to shit. They'd be just as excited as we would be to come and interact with a new sentient race. In reality, if they can travel faster that the speed of light, or just capable of travelling such distances at all, they'll be incredibly powerful to the point of being able to harvest suns for power and so on and so forth, so we'd pose no more threat than a termite. So stop getting an alien invasion hard-on.
Remember V'ger from Star Trek?

I think there's this other possibility that once we make our first FTL ships we'd become involved in the grand political and military schemes of the other interstellar factions in the similiar way China became part of the nuclear policies when they tested their first nuclear weapon. Wiping out a upstart race would make yourself look genocidial and a threat to everyone else.
How is this craft even still working? That's really impressive.
