Might ET be buried under too much ice to phone Earth? That’s what planetary scientist Alan Stern..., has concluded may be delaying our contact with alien civilizations.
Most extraterrestrial creatures are likely deep inside their home planets, in subsurface oceans crusted over in frozen water ice, according to a new proposal... The hypothesis could explain the lack of signals from other technologically advanced civilizations, a conundrum known as the Fermi paradox. It’s only recently that astronomers have come to appreciate how common oceans are in our solar system; evidence for them can be seen on several moons of Jupiter, Saturn, and Neptune, and even distant Pluto.... |

A new study from McMaster University indicates the nucleobases of RNA a precursor to or simpler form of DNA could have developed in small warm pools on top of Earth's rocky surface. Nucleobases are the building blocks of RNA and DNA and are found in space rocks and molecular clouds. Quote scientists have suggested that the very first life forms were RNA molecules, because they're found in all organisms, contain genetic information, can act like a protein in some ways, and can self-replicate."They fit the most basic definition of life," <<<<<<<<<<< The dry wet cycle theorized to turn chemistry to biology. Early on when earth was forming, many space rocks seeded with nucleobases would have been delivered to Earth intact as there would have been a very thin initial non oxygen atmosphere. |
As pools on Earth dried, the nucleabases would get pushed into more complex long chain RNA forms , rain or tides would rehydrate the pool and this cyclical process may have been the conditions needed for life to form. But this process of warm pool, condensing, compressing, refilling and repeating would be required for the RNA to become more complex. They point out, this process could not take place in an ocean as the drying of the pool is required to force the nucleobases into contact to form into RNA. Update Dec 31, 2017 >>>>>>>>>>>>> A new study out of the University of North Carolina indicates RNA may not have been the precursor to DNA but if I understand the new hypothesis correctly, the above small warm pools theory drying and rehydrating pushing nucleotides together could have still been the mechanism to initiate the formation of complex peptides in turn creating RNA and DNA. |
McMaster University is building a lab within a year to test this process experimentally. But the basic idea is that oceans don't provide the conditions needed to push nucleobases together.
You need land with pools and hot sunlight for the drying process. Locations with geysers like Yellowstone National park are perfect examples of this where microbial extremophile life exists. This microscopic life could have then been transported into the oceans. |
Ichthyostega was about three feet (one meter) long the tetrapod - or vertebrate - looked like a cross between a fish and a crocodile nearly identical to a large Salamander.
One key distinction between fish and mammals is the vertebrae. This is why aquatic mammals like dolphins move their tail up and down while fish like great white sharks move their tail side to side. As Ichthyostega's descendants moved onto land, their need to run and jump evolved into a vertebral spine that could flex up and down not left to right. Then some of those mammals migrated back into the oceans but still retained their spinal motion limitations. |

Its because of our Intellect, the ability to learn and reason, to adapt and predict.
Determining what intelligence is, is not so easy.

The scientists found that this myosin gene was still intact today in other primates, like chimpanzees and macaques, which have correspondingly strong jaw muscles.
An analysis of DNA samples showed the gene-inactivating mutation to be present in all modern humans worldwide. The analysis further traced the mutation's occurrence to a range of 2.1 million to 2.7 million years ago, probably 2.4 million. Ape skulls fully fuse closed within two years of birth with most having a sagittal crest. Once the skull fusses shut the brain can't grow any larger. Our skulls don't fuse shut until we are in our early thirties. This allows our brain to grow much larger. |
The temporal muscles connect to the lower jaw and the side of the cranium, these temporal muscles create the crushing force for the jaw.
Larger temporal muscles along with a sagittal crest are needed for greater crushing chewing force and this indicates most of the ape diet is fibrous plant material or nuts and seeds. Like humans, apes have incisors indicating some portion of their diet is meat. |
Home Habilis (2.1 to 1.5 Mya) is considered by many anthropologist as the first real human species which developed after Australopithecus an upright walking bipedal ape like species (based on hip and vertebral connection to the small brained skull) of which Lucy (one of the first upright walkers 3.2 Mya) was a part.
Australopithecus Sediba's tooth tartar demonstrate these upright walking ape like creatures mostly ate fruits, grains and fibrous plants lacking a need for stone cutting tools. There is debate over whether Habilis was the first of the homo (same) group. as some tools predate them but homo Habilis means "handy man". |
This means Habilis developed and used stone tools like the obsidian (volcanic glass) stone axe for chopping as well as the stone knife for cutting meat. Homo Erectus is the first known species to control the use of fire 1.7 Mya.
Learning how to create obsidian tools today can take modern humans with verbal instructions ten years to master. It takes planning and an understanding of how current actions will translate into future results. You need to be able to consider how your current actions impact future events to build complex obsidian tools. |
|
With the human genetic flaw MYH16 allowing skulls and brains to get bigger over time and the cognitive skills required for turning obsidian into tools along with the need for communicating these skills to future generations, it is thought this is what led to complex language, higher levels of intelligence and enhanced problem solving skills.
Since our jaw muscles were weaker than apes we needed to use tools to crush grains and bones to get at the marrow as well as cut hides for clothing. Since our jaw muscles were weaker our skulls and brains were allowed to grow larger to accommodate these complex learning needs. Homo Erectus (1.7 Mya) knew how to make obsidian tools and make fire thanks to a freak genetic flaw in our DNA. Three videos on this web site will give you a terrific understanding of our skeletal evolutionary history. |
All advanced technology is based on at least three things;
To shape intelligent thought into technologically functional forms you need dexterous limbs. Hoofs, claws. wings and fins don't have the dexterity required to form and shape objects conceived by an intelligent mind. For this you need fingers and an opposing thumb something tree climbers naturally possessed. |
<<<<<<<<<
Human foot vs. monkey foot. It's kinda freaky viewing a foot that looks like a hand. To be a tree climber you naturally need an opposing thumb along with tree branches to wrap the thumb around. Ice worlds don't have trees. Once we decided to walk upright, roam the land, shape rocks into tools and control fire, the need for a foot with an opposing thumb went away so our foot thumb became a big toe which aided in our ability to walk upright. Trees need land, soil, fresh water, sunlight and carbon dioxide. On Earth, as elevation increases trees gradually stop growing (tree line) due to a lack of water and heat. In other words, its cold and arid. |
What would there be to eat without plants on a planet? While extremophiles do exist on Earth, they only exist in microbial or microscopic form. Theoretically life began on Earth in the ocean about 3.5 bya as bacteria but ocean life has not evolved to be intelligent enough to develop any technology. A very specific set of circumstances came together on Terra Firma (land) to produce intelligent life. |

Hold the lit match away from the candle then with a short puff of air blow out the candle so the smoke drifts upward in a column.
Then place the burning match into the smoke (gas) a couple inches away from the wick. The match flame will ignite the gas and travel down the smoke column back to the wick and reignite it. |
The cycle of an atom (fission vs fusion)
Photosynthesis (fission = atom disassembly) and combustion (fusion = atom assembly) Sunlight energy is absorbed by a tree's leaf. The leaf breaths in carbon dioxide (CO2) through a nostril called a stomata. The tree's roots draw water up the tree through capillary action. The leaf takes the sunlight energy and separates the carbon from the oxygen (fission). The leaf exhales the oxygen and converts the carbon into cellulose (wood). A wood fire is the process of heat energy from burning gasses breaking the cellulose down so that the carbon is released. The carbon then combines with oxygen to form CO2. When carbon & oxygen combine, an explosion occurs releasing the Sun's heat & light. When you fan a flame you introduce more oxygen to the available carbon. This increases the number of fusion reactions which causes the fire to roar. |
Burning wood is sunlight energy being re-released from the wood in the form of heat and light.
Get that fire hot enough and it melts metals out of rock coalescing the metals into clusters of tin, copper, iron and other metals which become the materials we use to form a technological society. Our ability to make better tools increased with the use of fire. Without fire, no separating metals and no technology. Water worlds can't make fire. You need land, copious amounts of sun light and plants that can turn that sun light into storage packets like wood or coal. You also need intelligent animals with cognitive abilities to figure out how to combine all these elements to form technological devices. The intelligent animal needs nimble limbs with an opposing thumb. |
Is time the only requirement for intelligent cognitive abilities?
The dinosaurs had 175 million years to get smart but they didn't. All the creatures in the oceans have had much more time to develop higher intelligence but they haven't. A very specific set of circumstances led to our rapid rise of intelligence in a mere 2.5 My. Water creatures mostly have fins or claws. Cephalopods like the octopus, cuttlefish and squid have some nimble limbs and are pretty smart but they've never created fire or organized a rubik's cube. |
|
Without fire there would be no advanced technology. |
|
That leads me back to my original thought,
What in the world is going on in NASA science today? Its as if the more insane the concept the more easily its accepted. Quote from Alan's article Perhaps the equivalent of their “space program” would simply be boring through to the frozen surface of their planet, Stern suggests. Alan, WTF |
Update June 18 2019 Brian Cox weighed in on this debate today. The key point here is not simply the word life in the universe but "technologically advanced" life and in Brian's statement "galaxy". There is a massive difference between "life" and "advanced life". Microbial life began on Earth 3.5 Ga but complex life didn't begin until 542 million years ago during the Cambrian explosion and it wasn't a gradual shift from microbes to complex life it was geologically instantaneous and everywhere on Earth. Something different took place. What we call intelligent life didn't start until about 2 million years ago or even far more recent than that depending on how you choose to define intelligence. |
Light carries, within it, spectral lines of absorption similar to a barcode identifying the elements within stars and planetary atmospheres during ocultation.
This means we can know that the same stuff we work with here on Earth exists out there with the primary differences amongst them being the effect pressure and temperature has had on them. Yeah but anything is possible. |
How would fins be used to build a radio?
Fire doesn't burn in water. Plants need sunlight for photosynthesizes. Yeah but anything is possible. Then it dawned on me. If the truth sets you free, lies similar to ignorance enslave you. The more we live in ignorance the easier it is to accept and believe anything because we have no foundation of our own to stand on. My poor friend with his "yeah but anything is possible" response is like a leaf blowing in the wind tossed and turned, flipped and flopped because he has a lack of knowledge to stand on so yeah anything is possible becomes the mantra of the uninformed. |

Here's another cool party science trick,
Boil water over a flame in a paper cup. Paper easily burns when placed over a flame but place water in or on it and it will not burn until the water is gone. Water evaporates at 100 C or 212 F, evaporation is the process of removing heat. When the water evaporates it takes the heat of fire away from the paper preventing it from reaching its burning point temperature. Here's a one minute video showing you how this works. |
I continued to try to explain some facts to my friend.
Some things simply are not possible while others are required.
After all we haven't found any intelligent life yet anywhere. |
|
I'd rather stand for something and be dead wrong rather than mindlessly accept everything with "anything is possible".
When I take a stand, I am persistently challenged to test the correctness of my position. I Change my stand when facts don't support it but taking a stand in the first place is what drives my evaluation of its strengths and weaknesses. At least standing for something puts you in the game while swaying with the breeze puts you in the bleachers as a spectator. I suppose there's some comfort in being a bystander as you get to function as an armchair quarter back or back seat driver dispensing opinions without personal commitment or cost. |
Accepting everything without filtering it might seem like a more accepting and enlightened approach to life but it's really just simple laziness, its fear based.
Water, Terra, Fire, THINK!!! A day latter |

The TV show Expedition Unknown is running a special on aliens called The Hunt for Extraterrestrials (painful to watch).
At the beginning of episode four they capture, wait for it, wait for it, proof of aliens flying a spaceship around a bird man statue on Easter Island. Their amazing UFO footage looks identical to what UFOer's call rods. Watch this entire five minute video to see what rods actually are, watch to the end. |
|
Take out the ignorance by simply using a high speed camera run in tandem with a slow speed camera and all this UFO hype and proof looks as stupid as it is.
Its simply blurred camera images due to slow shutter speed and fast moving insects. Interdimensional beings, how spooky, how mysterious and yet how enlightened this fool sounds. Pseudo experts literally pull this stupid shit out their ass and feed it to the easily duped. I believe, I believe. my alien god, I believe. After all, anything is possible right? |
In episode one of Josh Gates aliens show they show some Egyptian hieroglyphs that look like a boat a tank and a helicopter and this is supposed to be supportive evidence of aliens giving the Egyptians advanced knowledge as if aliens flew helicopters.
Watch the video TV shows like this alien version of Expedition Unknown should be banned as it serves no purpose but to confuse the ignorant and gullible. Now add to that comments from scientists like Alan Stern and you have a society of confused people not knowing what to believe. |
