The local group?
The local group is a small portion of galaxies of which the Milky way is one.
Most of the Milky Way galaxy is unreachable for humans.

In fact, much of the star system of Sol is unreachable by humans aside from human built machines. The only off-planet destination humans have visited is the Moon.

We have the potential ability to reach Mars but that is still years, if not decades away.

The next step will likely be some of the larger asteroids and maybe a close proximity comet. A few of Jupiter's moons and Saturn's moons might be a destination but we don't have the technology and it won't exist for a very long time.

The SOLar System (Distance not to scale)



The Heliopause of SOL



12.5 Light Years from SOL


This map shows all the star systems that lie within 12.5 light years of our Sun. Most of the stars are red dwarfs - stars with a tenth of the Sun's mass and less than one hundredth the luminosity. Roughly eighty percent of all the stars in the universe are red dwarfs, and the nearest star - Proxima - is a typical example. Number of stars within 12.5 light years = 33

250 Light Years
The Solar Neighbourhood


This map is a plot of the 1500 most luminous stars within 250 light years. All of these stars are much more luminous than the Sun and most of them can be seen with the naked eye. About one third of the stars visible with the naked eye lie within 250 light years, even though this is only a tiny part of our galaxy. Number of stars within 250 light years = 260,000

5,000 Light Years
The Orion Arm
At the speed of light it takes 5,000 years to reach the edge of this area.
The light which is there now, left Sol about the same time the pyramids in Egypt were being built.
The white shaded area represents stars, not planets. Many stars have planets.


This is a map of our corner of the Milky Way galaxy. The Sun is located in the Orion Arm - a fairly minor arm compared with the Sagittarius Arm, which is located closer to the galactic centre. The map shows several stars visible with the naked eye which are located deep within the Orion arm. The most notable group of stars here are main stars in the constellation of Orion - from which the spiral arm gets its name. All of these stars are bright giant and supergiant stars, thousands of times more luminous than the Sun. The most luminous star on the map is Rho Cassiopeia (ρ Cas) - to us 4000 light years away, it is a dim naked eye star, but in reality it is a huge supergiant star 100 000 times more luminous than our Sun. Number of stars within 5000 light years = 600 million

50,000 Light Years
The Milky Way Galaxy


This map shows the full extent of the Milky Way galaxy - a spiral galaxy of at least two hundred billion stars. Our Sun is buried deep within the Orion Arm about 26,000 light years from the centre. Towards the centre of the galaxy the stars are packed together much closer than they are where we live. Notice also the presence of small globular clusters of stars which lie well outside the plane of the Galaxy, and notice too the presence of a nearby dwarf galaxy - the Sagittarius dwarf - which is slowly being swallowed up by our own galaxy. Number of stars within 50,000 light years = 200 billion

500,000 Light Years
The Satellite Galaxies


The Milky Way is surrounded by several dwarf galaxies, typically containing a few tens of millions of stars, which is insignificant compared with the number of stars in the Milky Way itself. This map shows the closest dwarf galaxies, they are all gravitationally bound to the Milky Way requiring billions of years to orbit it.
Number of large galaxies within 500,000 light years = 1
Number of dwarf galaxies within 500,000 light years = 12
Number of stars within 500,000 light years = 225 billion

5 million Light Years
The Local Group of Galaxies


The Milky Way is one of three large galaxies belonging to the group of galaxies called the Local Group which also contains several dozen dwarf galaxies. Most of these galaxies are depicted on the map, although most dwarf galaxies are so faint, that there are probably several more waiting to be discovered.
Number of large galaxies within 5 million light years = 3
Number of dwarf galaxies within 5 million light years = 46
Number of stars within 5 million light years = 700 billion

100 Million Light Years SOL
The Virgo Supercluster
The local group of galaxies is just one of many centred around the massive Virgo Cluster. Collectively, all of these groups and clusters form a unit known as the Virgo Supercluster.

1 Billion Light Years from SOL
The Neighbouring Superclusters
The distribution of galaxies in the universe is far from regular. They tend to clump together into huge supercluster formations.

14 Billion Light Years from SOL
The Visible Universe
Although our knowledge of the large scale structure of the universe is incomplete, many large and small scale features are visible right out to the very edge of the visible universe. The entire universe is fairly uniform.

There's a lot more to the article.



How would 'sometime soon' be defined?

The proposed ark base and structure

The surface base


Sub-surface structure



Quite a claim!
Technology which does not exist does not mean it will exist.
Plus, 30 years is extremely ambitious even if the technology existed right now.


"cryogenically preserved genetic material" is not the same thing as losing 6.7 million forms of life on Earth.

"at least 250 rocket launches" represents a very small portion of the proposed mission. Insignificant, really, from the entire start to finished project.
Even if the mass is lifted from the Earth to mid-Earth orbit that's still a lot of mass. Plus, that mass will each be moving at tremendous speed. Mass which will have to be then slowed (and eventually, stopped) at its destination. So in addition to 250 rocket launches, there will need to be 250 rocket landings. Plus, control burns, deceleration and orientation corrections.

There's a possibility the mass could be collected in mid or high Earth orbit. Then coupled with a different guidance control system, transported to the Moon and set in Lunar orbit, coupled again to a landing guidance and control system. This increases the number of launches and the subsequent mass lifted to allow building of the two special guidance and control systems in space. At least one of which will need to be transported to the Moon as its final destination. Plus the ferry units would need to make multiple Earth-Moon, Moon-Earth transits. Now the Teamsters Union gets involved.
Plus, the article mentions nothing about a ferry type transport system.


Relatively speaking it would be easier but this implies a trip to the Moon is easy, its NOT. Not only is it difficult, its expensive and fraught with dangers. Plus, any increase in mass increases the difficulty, the costs and the chances something can go wrong.


"quick, back-of-the-envelope calculations"!
I thought we were talking about scientists. Anyone can do 'quick, back-of-the-envelope calculations' but it doesn't mean it has any significance.
Plus, transporting the actual samples to a completed Lunar Base is additional launches, also where something can go very wrong. However, due to the reduced mass of the payload it would be easier, not more difficult.


More like tens of trillions. Plus, the project wouldn't be governmentally run. Any large, long duration endeavor in space will need to be backed and managed by the public sector. Governments are too unstable and public opinion changes too frequently. Wars and disasters interrupt things.


LOL, only one! What we have here is a delusional scientist pushing a pipe dream. Typical of the nature of science documentaries and media-seeking funding strategies.


Not in your wildest dreams. This is like saying a home can be built from raw forest with hand tools in a week.
I'm amazed Live Science posted this article under NEWS.

Sorry, I just don't 'buy it'!


If it were a done deal aside from the construction process and localized change in the immediate area plugging a lava tube could affect pressure balances from its pristine condition. A significant increase in mass would be need to change the Moon's orbital mechanics to a point it would matter but it would change the mass of the Moon so in the very long run it could cause orbital change over time.

Which means a body in the near vacuum of space is affected by change within that body. Increases and decreases in mass affect the motion of mass in space.

However, this proposal could be considered on-topic.
Genetic material on the Moon makes that material aliens. Extraterrestrial aliens.

PS: One more thing which must be considered.
Solar and cosmic radiation outside the Earth's Van-Allen belt protection.
A 'seed vault' implies a long duration storage facility.
Possible centuries of storage.
We cannot know the effects of this radiation over long duration.

Outer belt = 12,000-25,000 miles.
Moon = 250,000 miles
The Moon is outside the protection of Earth.
The Earth has a magnetosphere / The Moon does not.

Aliens Might Exist !!!

You may be right as I reckon the guy next door is one

The Moon will probably last about the samer time as the Earth...4.5 billion or so years. As it gradually contines to move away from the Earth, eventually its fate could be a bit different (thrown into the Sun or thrown out to Mars).
If its final Earth orbit occurs while its moving away from the Sun, anything on it would survive a bit longer (till it collides with something).

No, I would not donate my seed to an ark.
If there is a catastrophe on Earth requiring a re-population from zygotes, the technology and ability would also likely be destroyed preventing retrieval of those 'seeds'.

It would be easier to retrieve genetic material preserved in the middle of Antarctica. The South pole is the best location in all scenarios. Even that may prove a huge undertaking for a civilization remaining on a devastated planet.

The whole idea depends on whether someone who knows the location of the ark and how to actually get there and knows how to germinate the zygotes into actual living breathing animals and growing plants survives.
Even electronic records would be useless if there is no longer an electrical grid available to the survivors.
Plus, the window of such a recovery may expire before the effort can be implemented.
The Earth will probably recover eventually but there's no guarantee the human race will.

Automated systems might be included but the sequence and timing of such a complex task would require an army of highly specialized machines working without failure.

A better method would be the development and use of nano-machines called nano-assemblers and nano-disassemblers but there would need to be an exceedingly dependable quantum computing AI to coordinate it all.
Nano-machines could repair the planet by rearranging atoms.
Eric Drexler's Engines of Creation talks about this.

Engines of Creation 2.0: The Coming Era of Nanotechnology
Originally published in 1986, K. Eric Drexler's Engines of Creation laid the theoretical foundation for the modern field of nanotechnology and articulated the amazing possibilities and dangers associated with engineering at the molecular scale. Unique for both its style and substance, the book is today recognized as the seminal work in nanotechnology and has earned Drexler the title of "Father of Nanotechnology."

i met a guy years ago buying a 6 pack of beer he was the cashier...he told me he was abducted and wrote a book about it and says he likes to talk about it...he says when he came back every hair on him was grey....he was only 30...we planned a meeting and i chickened out...he really creeped me out a bit...personally i don't think their are aliens but if there are they are really cagey sneaky b*st*rds. of course then you look at my profile pic and wonder wtf?

For me there are no aliens, only souls coming from source.
