Von Neumann Probes don't exist. They're a thought experiment, not a real technology that can exist.
Don't confuse science fiction with actual science

>>11958135
If von Nuemann probes exist, why isn't the universe filled with intelligent life anywhere else?

>>11958143
Couldn't they have applications for planetary or meteor mining? I.e. the probes do the actual mining and also replicate based off of materials that they are mining thus eliminating the need for any maintenance because as one probe breaks, more will be created?

>>11958135
There are very, very few planets with environments suited to support carbon-based lifeforms relative to the grand scheme of the universe. The likelihood of life occurring even once is already EXTREMELY tiny, and the likelihood of that life not dying off quickly and evolving into complex, intelligent lifeforms is even more small. Humans are very likely the only intelligent lifeforms in the universe despite how much pseuds will hope it isnt true. It is possible that microscopic unicellular organisms exist in one or a few other habitable planets, but the chances of there being multicellular, complex, intelligent life elsewhere in the universe is next to zero.

>>11958135
If intelligent life exists on Earth, why isn't the universe filled with Von Neumann probes?

>>11958135
Because Von Neumann is a hack

Yet another contribution. Holy shit, the BRAINS on that man.

>>11958212
Complete bullshit. Life started on Earth extremely fast so it's not hard to start at all and there are billions of potential planets like Earth in our galaxy alone.

The only problem is how long it takes for intelligent life to appear and if intelligent life is even always the end goal of evolution.

I doubt there are many civilizations in our galaxy but they definitely exist.

>>11958135
We happen to live in the only area of the universe that hasn't been filled with von Neumann probes.

just accept it. fermi paradox has already been debunked

>>11958418
Based. Life isn't real. All motion in the universe is merely hallucination, a misapprehension of the single, unchanging arche which is all, and which all is.

>>11958432
There are at least 10 billion planets in the galaxy with advanced life.

>>11958212
>>11958349
Not how statistics work.
We don't know the probability of life beginning.
Anyone who claims to is a retard.

>>11958437
Wow that's pretty hashtag deep, faggot

>>11958448
oh

>>11958135
by the time a civilization can make anything resembling a von Neumann probe, it will have realized it makes no sense

>>11958432
>>life occurred when the perfect conditions for it were maintained for a statistically unlikely amount of time

Faggot Earth was a hellhole back then.

We will 100% find microbes on other planets in solar system.

We've already found fossilized bacteria on mars.
Anyone who doesn't accept that the universe is teeming with advanced alien civilizations is coping. I don't know why though.

What if you were the von neumann probe all along?

Because we're the first. Either the Shadows or the Vorlons.

>>11958135
Bob elected to limit his number of copies to reduce the chance of contacting another, possibly hostile civilization.

>>11958135
Maybe an advanced enough civilization can make invisible von neuman probes. Or something so much weirder we humans can't even conceive,

kubrick has interesting thoughts on the subject http://dpk.io/kubrick

>>11958212
Large degree of speculation in this post to the point everything you claim is totally invalid. Im surprised you feel confident enough to speak with such certainty

>>11958135
Aliens are too dumb and gay to compete with the intellect of Von Neuman. They are probably some retard bugs that took 3 million years of sentience to get to low orbit

What if von Neumann probes don't look like anything we'd recognize? What if planet 9 is a probe? What if lonely planets crusing through space, not attached to any solar system, are von Neumann probes?
What if it's not the probes themselves replicating but the life forms inhabiting the probes?

>>11959283
That's a really good point, how would we even detect a Von Neumann probe, let alone recognize it if we did?

It's like the Fermi Paradox, completely based around Human perception. Would we even recognize Alien technology or presence with our current level of technology?

We scan the universe for radio signals looking for intelligent life, we may as well be searching for smoke signals

Arent lifeforms just Von Neumann machines? At the molecular level all known life looks like sci fi nanotechnology. What makes you think that selfreplicating machines can be made any more efficient than evolution managed to do it? Maybe all the "weaknesses" of life are actually a necessity to a robust replicator. People like to imagine nanomachines as some grey goo, but what if it cant get any better than green sludge - microbial life today - due to physical constraints.

>>11958418

>>11958711
>We've already found fossilized bacteria on mars.
We haven't. We might though after Perseverance arrives to Mars.

>>11958212
We know with very high likehood that planets similar to Earth are common. The only ways our solar system is somewhat unusual is that there are no hot gas giants on near the sun or its and the rocky planets are rather small. Other solar systems tend to have big rocky planets as well.

>What makes you think that selfreplicating machines can be made any more efficient than evolution managed to do it?
Evolution isn't a conscious being. It's a repeating process of mutation and natural selection in reaction to a changing environment. It strives for function, not perfection. With proper genetic engineering and maybe nanotechnology we could create something that no natural being could even begin to compare to.

>>11958691
>We will 100% find microbes on other planets in solar system.
Yes, on Mars.
But that's because we sent them there...

>>11958890

Good stuff. Thanks.

>>11959372

>>11958143
Haha, yeah no kidding. These retards who believe that self replicating machinery could exist are smoking crack. Never in the history of the universe has anything replicated by the trillions which would be required to fill a large space.

False, simply asserted without evidence. There is no reason to suspect that the carbon based biological organisms are not already the pinnacle of nanomachines with respect to the laws of physics and chemistry (and protip: they are, meaning there does not exist a combination of atoms that form a more efficient/superior nanomachine than the biological cells we already have on Earth).

>>11959719
And the Cope continues

>>11959726
>There is no reason to suspect that the carbon based biological organisms are not already the pinnacle of nanomachines
What stops us from improving upon that design?

>>11959740
There is no design that exists in the combination of atoms that is an improvement.

>>11959728
He's right though, we have no idea of how probable it is that life (as we define it) will spontaneously appear given the right conditions. We only know it happened once.

>>11959808
I see it simply: The moment we find a single other planet with life, by the principle of induction we know there are literally billions if not trillions of planets with life.
Do you seriously think we're never gonna find another planet with life?

It's cope, dude. The universe is absolutely teeming with intelligent life and civilizations just as sophisticated as our own.

>>11959837
>The universe is absolutely teeming with intelligent life and civilizations just as sophisticated as our own.
I believe that life outside Earth is possible, but this claim is a bit of a stretch. Let's first find complex alien life, and then we'll see.

>>11958157
provide proof

>>11958135
>If intelligent life exists anywhere else

There are billions of galaxies.
What if intelligent life occurs about once per galaxy.
There would be many intelligent species but the distance between galaxies is HUGE.
Sending any material object between galaxies would require millions of years.

>>11958135

Because the universe isn't filled with life, not sapient life anyway, not yet. We live within the first 1% of the lifespan of the universe. Give it time.

>>11959451
I agree that that could be, but Id say we have no clear evidence towards that. I'm sure there are things that cpuld be improved, but can you get improvements of orders of magnitude?
So far we have never created more complex technology than biology imo. Our technology relies on amplifying some aspect with brute force. We can't build a robot that's physically more capable than a human, but we can build a huge excavator that's really good at one thing. Similarly we can't (yet) build general AI, but we can build computers that outperforl us at specific computations.

>>11958135

There are so many planets that life almost has to exist somewhere else.

>>11958135
It's unlikely that another Von Neumann emerged in other civilizations.

>>11958394
Only if the probes send messages back home and those messages (or at least their direction) are intercepted. There are ways around this problem, like only messaging back once the probe has determined that there is no advanced civilization observing it, or wasting power and time by sending an omnidirectional signal to obfuscate its destination.

>>11958768
Unless he set the reproduction rate to zero or negative, exploration would ultimately result in contact. Eventually some Bob would encounter whatever is there to encounter, which they basically did.

>>11959837
Probably, but they're all too far away to ever reach. FTL is bullshit. We're actually all stuck in our own little petri dish.

>>11958135
Because it's fictional technology.

>>11958135
Because we’re alone

How are you sure it is not?
