Trillions of tiny alien ‘robot probes’ may be flying in space but are too small for Nasa to spot, shock paper claims

SPACE scientists may have missed alien probes because they're just too small.

That's the bold claim from an astrophysicist who reckons we've been looking for extraterrestrial life the wrong way. The argument is an attempt to explain the Fermi Paradox, a decades-old thought experiment.

It says that the universe is so unimaginably vast that the chance of alien life existing is quite high – and then asks, where are they? No one really knows that answer, except perhaps astrophysicist Zaza Osmanov of Georgia's University of Tbilisi.

He thinks that aliens might be exploring the universe using tiny robots that measure just a single nanometre. It's based on the idea of Von Neumann probes. This is the theory that aliens could send self-replicating spacecraft out into the universe to explore in a risk-free way. But these self-replicating probes could easily run out of new materials to function properly.

In a paper, Osmanov argues that these probes could instead be built on a nanoscale. The robots could then use hydrogen atoms from interstellar dust to power themselves. These nano-droids could already be floating around, but we may not have spotted them because we're looking for larger evidence of alien life.

"The conventional approach to the search for extraterrestrial intelligence implies the search for artificial radio signals, or interstellar beacons targeted at the Earth," Osmanov argues. "But...the mentioned method strongly restricts the search."

In his paper, Osmanov reveals detailed calculations about how it may be possible to spot these nano-robots. He says that they could easily self-replicate into a swarm numbering trillions of billions. This swarm of probes would give off some light as they hoovered up photons along their journey. And Osmanov says that they might look just like a comet several kilometres across, appearing as infrared light.

"All the...results indicate that if one detects a strange object with extremely high values of luminosity increment, that might be a good sign to place the object in the list of extraterrestrial Von-Neumann probe candidates," he wrote.

"We have considered the scenario when the Type-II civilisation needs to 'invade' the interstellar clouds by means of the self-reproducing robots. "And it has been shown that this process will inevitably lead to the observational consequences."

However, they would likely only be visible if they remained as a swarm – and would almost certainly be too small to spot if travelling on their own.

On the interstellar Von Neumann micro self-reproducing probes

ABSTRACT In this paper we consider efficiency of self-reproducing extraterrestrial Von-Neumann micro scale robots and analyse the observational characteristics. By examining the natural scenario of moving in the HII clouds, it has been found that the timescale of replication might be several years and even less - making the process of observation quite promising. We have shown that by encountering the interstellar protons the probes might be visible at least in the infrared energy band and the corresponding luminosities might reach enormous values.

James Rink has talked about Femto technology which is 10 to the -15th. I imagine races could use nano-machines to terraform planets.

I can't stop thinking about this story. lol

Do you think it could be the explanation for the Hessdalen Lights? After all the phenomena is not just limited to the one location. There are several locations around the world that report this light gathering. Maybe they group together at certain times to refuel each other or share/compare/swap data? Maybe they have to group/join together to produce enough power to send data back to whomever/whatever sent them on the mission?

If aliens sent out billions of tiny probes into various star systems, what if a probe detects lifeforms on a planet, perhaps interesting lifeforms, would they then send out millions of tiny eavesdropping probes down on the planet's surface and monitor everything going on?...

Surely if alien have the ability to send billions of probes in space then they can easily send millions of probes to a particular planet's surface, underwater, virtually anywhere on the planet...

Great! All-consuming paranoia of two peoples with considerable life experience...
nivek, don't worry. If aliens will want to establish total control over someone and to play dolls, they will do so with single citizens of USA. You won't feel any pain.
Are you bored in life? Read the books, travel, discover this planet for youself. The possibilities of your mind are unlimited by somebody. You have such wealth as absence of intervention into the full development of your mental abilities, which increase your value to society. You have such wealth as human dignity which is not destroyed by artificial biochemical way or with help of daily crying or thanks to the stupidest stunts from your side.
Answer to me, how can it be that after two years of friendly communication with representatives of extraterrestrial civilization people opens his wrist screaming "I don't want to endure this one more minute!" and after a while to commit suicide throwing himself under a car, as it was in Belgium in February 2013?

More like momentary consideration of possibilities stemming from alleged unknown extra-terrestrials, not ultra-terrestrials, not interdimensional-terrestrials, but flesh and blood trespassers to our world...If they send machines, perhaps sooner or later bodies will follow...
