that’s surely on the wish list of every capitalist – but robots can get computer-virus too 😉
Life on earth is possible since 3.5 billion years
- the “modern” human is around since 10.000 years – this is 0.000002857% of the whole “life on earth” story
- okay let’s say 200.000 years that is 0.0000571% of the whole “life on earth” story
…but surely with astonishing speed of growth and development and with massive impact on the biosphere and atmosphere.
Chimpanzee and Human genetic divergence between populations may have occurred as early as 13 million years ago (Miocene) (than it would be 0.00371%) hybridization may have been ongoing until as recent as 4 million years ago (Pliocene) (than it would be 0.00114%) (src)
Some Russian nut bold predicts – that in two or three decades there will be “Einstein like” AI machines ( i am not SOOO optimistic about it, what if the “free market” does not want them?) and solve all our problems – like energy problems (that’s what market capitalism clearly DOES NOT WANT, who will energy monopolists sell oil to if a super-AI solves all problems?)
The Super-AI will even do our dishes and wipe our asses – so we can be finally: lazy as heck.
Or: the Super-AI takes over the world and replaces mankind with robots. (As in the Terminator or Matrix movies)
Stephen Hawking: “We can not know if we are infinitely helped – sidelined – or destroyed by AI”
“Unless we learn how to prepare for the potential risks – AI could be worst invention in the history of our civilization”
“Autonomous weapons or the few to oppress the many”
“The rise of AI could be the best or the worst thing that ever happened to humanity”
“I am an optimist – but we need to be aware of the dangers”
Until then a lot could go wrong as well:
- war including nuclear, chemical and biological
- does not accidentally poison itself with the latest plastic softener
- climate-change kills our crops
- a meteor comes crashing down on us
- an inter galactic super emp fries our atmosphere
… yes. alot can go wrong! and youngsters do not appreciate any breath they take. (there used to be way more oxygen on this planet… and mars even had an atmosphere and rivers and oceans… which went missing as it’s magnetic field collapsed 4 billion years ago.
So if you go fossil hunting on mars – expect them to be at least 4 billion years old.
funny thing: almost exactly after mars when dead and dry – life became possible on earth – 3.5 billion years ago.
okay a little gap of 500 million years.
Time-line of the evolutionary history / emergence of life on planet earth:
also interesting: 5x mass extinction events
not just one that killed the dinosaurs.
- maybe climate changes, massive volcanic eruptions and human overhunting
- Supernova? meteor: Eltanin impact?
- climate change due to change of ocean circulation patterns and perhaps related to the Milankovitch cycles?
- meteor: Popigai impactor?
- meteor: Chicxulub impactor; Deccan Traps?
- meteor: Caribbean large igneous province
- Karoo-Ferrar Provinces
- Central Atlantic magmatic province; impactor
- Wrangellia flood basalts
- Siberian Traps; Wilkes Land Crater; Anoxic event
- Emeishan Traps?
- Viluy Traps
- Changes in sea level and chemistry?
- Global drop in sea level?
- Deep-ocean anoxia; Milankovitch cycles?
- Global cooling and sea level drop; Gamma-ray burst?
- Rising oxygen levels in the atmosphere due to the development of photosynthesis
as you can see in this animation of the American natural museum of neutral history (or the other way around):
Agriculture and ISLAM is clearly to blame for OVERPOPULATION X-D (this explains EVERYTHING!)
- it took 200.000 years to reach one billion, but only 200 to reach 7 billion
- ISLAM: GIVE MORE RIGHTS TO WOMEN! So they can say “NO” to the 10th child that they can not sustain.
- CHRISTIANITY (esp. Pope!) BOMB EM WITH CONDOMS!
NO PANIC: If current trends continue global civilization will peak at 11 billion in 2100, because average fertility rates are falling in almost any country. (to 2 x babies per woman in 2100)
BUT MAYBE NOT:
Earliest Life forms: “Rocks of Bacteria” Stromatolite
“Astrobiologists are particularly interested in these localities because of the search for life on Mars. Earth and Mars probably shared similar early histories (i just HOPE earth does not share Mars’ fate of a desert-like, life-unfriendly planet with atmosphere that almost only (96%) consists off Co2… but i guess we are heading this way… luckily we still have our magnetic shield/field) and recent exploration has uncovered considerable evidence that Mars once had environments suitable for stromatolite growth. If stromatolite-like structures are found on Mars, the Pilbara localities will provide significant analogues for comparison with potential Martian fossils.”
“Mineral and petroleum explorers are also interested in understanding where and how microbialites and other early fossils form. There are many examples worldwide where mineral deposits have formed in and around microbialites, by mineral-rich waters flowing through the spaces within the mounds and depositing ore minerals. The spaces in the microbialites can also trap and store hydrocarbons like gas and oil. The organisms that form microbialites are a known source of petroleum, making them interesting targets for petroleum exploration.”

What plants could grow on mars?
“The surface receives less than half the amount of sunlight that Earth does, and dust in the atmosphere can attenuate it even more. Due to the absence of an ozone layer, more ultraviolet radiation reaches the ground. As to the Martian surface itself, the dirt (technically “regolith”) is more iron-rich, particularly in iron oxides.”
“Mixed greens such as lettuce and kale did well, but potatoes — the mainstay of protagonist Mark Watney in The Martian — did not”
“The clay-like Martian simulant was so thick that it crushed the growing taters, giving them no room to expand.”
“Overall, plants did much better when the students added filler such as coffee grounds to the Martian simulant, Guinan says. The filler fluffed the dirt up enough that water could percolate through and reach the roots.”
“One major difference between the Villanova project and real Martian soil is perchlorate (CClO4).
Perchlorates abound in the uppermost layer of Martian regolith, potentially lowering the freezing temperature of water enough to explain some fleeting signs of liquid water activity on Mars.”
“But perchlorate is toxic to humans, causing thyroid problems and even death.
Humans on the Red Planet might breathe it in from dust that infiltrated habitats, and growing food with it would be dangerous.
“Matt Damon would have died,” Guinan said, referring to the Hollywood version of the novel.
“It was never mentioned in the movie, you know — you don’t want to talk about things like that.”
Farmers on Mars will need to remove any perchlorate from the Martian soil before using it. One way is to rinse the soil, since perchlorate dissolves in water. Another, more enticing way is to use perchlorate-eating bacteria, which produce oxygen as a metabolic byproduct. That might protect the colonists from serious health problems while also bolstering their breathable air supply.
For those interested in doing similar projects with their students, Guinan recommends lettuce. “It grows fast, and you can eat it,” he says. “I ate the lettuce. I’m still here.””
the worst weather on mars you can IMAGINE: like 3 year long DUST STORMS
that block almost all sunlight… a lot of mars probes have fallen victim to missing sunlight on Mars’ atmosphere and it seems that Rover Opportunity is now sharing their destiny.
“Opportunity hasn’t made a peep since June 10. Around that time, a developing dust storm shrouded its environs in darkness, preventing the solar-powered rover from harvesting enough sunlight to recharge its batteries. ” (src)
Stuff to watch:
(if you are really really knowledge hungry or bored on Friday nights because you wait for your gf to arrive X-D and you really wonder if she is cheating on you)
luckily she also likes documentaries… but her English sucks. ?
