Aliens

The universe is rather large, one would think that somewhere out there is a planet with sufficient atmospheric oxygen to sustain us. If you take a respirator with you, perhaps even that is not a limit.

I saw in a recent program that actor Jeff Goldblum succeeded in a teleportation experiment, but with a very bad outcome. A fly got in the booth with him and its genes merged with Jeff's.
Casket had to be closed at the funeral.

 

The pic you posted bears a remarkable likeness to what happened to him.

There is a hall of fame for people who are the first to try things.
If you try teleportation and are successful, how would we know that you succeeded? You'd have to come back to us reasonably intact.
If your body goes on a one-way journey to a distant side of the galaxy, we may never know if you survived the journey.

 

an actual teleportation experience informs my opinions . i sure do
think differently , more originally about the nature of space . nothing
bad happened , the transition was seamless , i didn't intend to
have it happen , my backpack and flashlight came with me , i can
ponder the details of my memory .... from all this i might began to assemble
assumptions . for instance : galactic travellers do not need a starship .

as to human nature , we are extremely specific to this earth and
our moon , too .

even to spend a few hours on the moon and that's
about enough of that . lunacy happens .

 

Don't get bored with this too quickly. The real action starts at the 3:15 mark.

We are selves are aliens

 

So what evidence is there that we did or did not evolve on this planet?

First, consider our biochemical makeup..
Does our personal chemistry closely parallel Earth's chemistry?
On one hand, we cannot assimilate elements into our body that are not available on this planet, but what about the ratio of various trace elements? Do they mirror what is found on Earth?

I'll start with our blood salinity...
It is lower than the sea's salinity, but these lower levels may reflect adaptation of our recent primate ancestors to life at the margin of brackish marshes rather than our more distant non-mammalian ancestors, presumably some sea creature living in the full salinity of the open seas. In other words, we need not assume that our origin must be extra-terrestrial based on blood salinity.

So let's look at other minerals...
Our body requires certain trace elements such as iodine, iron and selenium. Iodine is not abundant deep in the interior of continents, but if we lived close to the sea, the food chain would provide it in our diet. Dietary selenium and iron are needed for optimum health, but we can survive where it is not abundant in the soil.

Vitamin C is essential to the human diet. We can get it from meat or a wide variety of fruits, some of which can be stored for consumption in winter. Do plants on other planets have vitamin C? Someone please go find out and report back as soon as possible. So this issue is not proof either way.

If we lived life in our naked natural condition, humanity would be confined to the tropics because of our inability to survive the kind of cold that occurs beyond the tropics (without clothing or fire or both). That does not prove that we are not from planet Earth, nor does it offer evidence that we are from Earth.

People with ancestors from Europe or northern Asia are usually too fair-skinned to survive in the tropics without clothing, but that is a recent evolutionary adaptation to the extreme low-light environments their ancestors migrated to. Most of humanity is still deeply pigmented enough to survive tropical levels of sunlight. Humans evolve different skin color quickly in adaptation to UV light in the part of the world they live in. Because our skin color evolves so quickly, it cannot prove nor disprove extra-terrestrial origin. It does seem to prove that we did not come from a planet that receives NO UV light (even the fairest among us must have a source of vitamin D). In the darkest cloudiest parts of Europe, vitamin D comes primarily from seafood rather than sun on human skin, but the sea animals themselves must manufacture vitamin D and to do that these animals must themselves have at least some UV radiation exposure.
We can also safely surmise that humans did not evolve under a star that broadcasts so much UV radiation that even the darkest (most-protected) humans would be damaged. If we are extra-terrestrial, the home star must be somewhat analogous to our present star, but it makes more sense to believe that Sol is our home star apart from any other evidence to refute that claim.

Our lungs are adapted to our present environment, but there is evidence that we can evolve quickly to atmospheric changes. People in the Tibetan plateau and in the high Andes evolved higher lung capacities and stockier bodies to adapt to low-oxygen regions of Earth. Of course it begs the question: Are they are the original type of human as it first appeared from a distant low-oxygen world? Did the rest of us evolve to adapt to a richer atmosphere? But in fact, we heal faster in a hyperbaric chamber. Lower the partial pressure of oxygen slightly to offset increased risk of oxidant damage and increase CO2 and nitrogen up to 2 atmospheres and you get the optimum environment for human metabolism. This would incidentally lower our UV exposure. But this may only offer the possibility that our "Eden" was simply Earth before some calamity that blasted away part of our atmosphere rather than proof that we come from another planet. Many plants also do better in a denser atmosphere with slightly higher CO2 concentration, so it seems to indicate a change in Earth's atmosphere from our distant past rather than indicate extra-terrestrial origin for humans.

Of course if humans were brought to Earth from a planet with essentially identical atmosphere, gravity and climate to Earth, there would be almost no way to prove our planet of origin.

 

Nice analysis, Garden Guy!

Just one niggling little point occurs to me: If we increased the amount of CO2 in the air while decreasing the partial pressure of oxygen, would that not impair our ability to inhale oxygen and exhale CO2?

 

What if we double the total atmospheric pressure while cutting 02 from 20% to 10% to 15%? of total gases? Some change in that range would still promote faster healing but we wouldn't want 02 to be so high that oxidants become a problem.

What if we simultaneously increase CO2 from its present 0.038% to 0.076%? (while doubling total atmospheric pressure?

I guess Nitrogen, water vapor or some other inert gas could serve to increase air pressure to offset the lower o2 percentage.

It is not necessary to postulate an extra-terrestrial origin. Perhaps Earth once had the ideal gas ratio for both us and plants as well as higher overall pressure. I read a study on Pterodactyls and it seems that they could not fly with present air pressure unless there were constant winds. Not impossible to have such winds by the coast, but I think it more likely that Earth in the late Jurassic had a denser atmosphere. What about Homo erectus some 2 million years ago? Did these recent relatives evolve in a different atmosphere? There were no Pterodactyls by then, so we would need to look for other evidence of past atmosphere.

I would have to ask some volunteers to live in a hyperbaric chamber with the above-mentioned gas ratios for a few weeks to test my theories. Any volunteers? It might make you more youthful!
Michael Jackson slept in one when he was healing from a bad scalp burn (Pepsi commercial gone awry)

 

I see that doubling the pressure while cutting O2 would probably get O2 into our lungs, and I understand what you're saying about oxidants. And frankly I didn't realize the percentage of CO2 in the air was that miniscule. At that level, I suppose doubling the percentage and doubling the pressure would probably not much deter the osmotic pressure of CO2 from our lungs to the air.

And your overall point is clear, and a good argument. It's not necessary to postulate extra-terrestrial origin.

It's interesting to consider the possibility that the Earth's atmosphere might once have had more the composition you're talking about - though I'm kind thinking there would have been less CO2 instead of more, cuz doesn't the evidence point to there being lots more jungly environment in the dinosaurs' time, which would have meant more of the atmospheric carbon would have been fixed in plant structures?

What kind of evidence would show higher past atmospheric pressure, I wonder...

Also btw, regarding your earlier point about our blood salinity, I seem to remember learning some years ago that the salinity of our blood approximates the salinity of the Earth's oceans at about the time that multicellular animals started evolving closed circulatory systems.

I wouldn't mind trying out your hyperbaric chamber, except you would need to pay me for lost time from work, and you would need to supply me with sufficient entertainments...

 

Giant bugs.

I believe in aliens.

There is very much tales, myths in Sakha of aliens, UFO and mysterious places. For example, people who did not view my old post, maybe you will enjoy: http://www.realufos.net/2011/10/close-look-at-valley-of-death-yakutian.html

When I was Age 6-9, in Summer Time, my father would drive us out from city. From my home city, is possible to travel East-West for 2000 miles total, see only ice, no people, and no light. Night sky is extremely beautiful and clear from this distances. We do still remember very clear: purple colour, flashing triangle object in the sky. It was rotating, and moving slow in the direction away from us. I believe probably this is military, but it was strange, I like to think it is more! ))

Unfortunately, no more experience like this, but if I am fortunate.

 

So...if I could get more oxygen I could have a bigger body?

Well so there was more oxygen in the dino days. However I'm betting that a million or two years ago when our ancestors were starting to differentiate from the Great Ape predecessors, there was a lot less jungle, a lot more arid areas, and a much lower oxygen content.

But Justin, this really doesn't address the atmospheric pressure issue, does it? Just the oxygen content.

I can accept the possibility that there are wondrous things in the universe that my weensy little mind cannot easily accept, and alien visitations could be one of those wondrous things. However one thing that kinda bothers me is: Why do accounts like the ones on the website you posted always seem to appear on flakey websites, but we never see anything in bona fide scientific journals by bona fide scientists? Does anybody have any thoughts on this?

 

A peer-review science journal has a greater burden of proof and requires more exacting descriptions, tests, etc before publishing findings.

If I saw something in the night sky that could obviously not be explained by optical illusion, space junk, heavenly bodies, terrestrial aircraft and spacecraft, then there is a good chance that it is a vehicle (manned or drone who can say?) of extra-terrestrial origin.

However, I could not get such a finding published in a science journal for the reasons specified above, even if it meets reasonable burden of proof for the general public.

Also scientists tend to operate on paradigms, or working general principles of how things are.
Stories that involve the paranormal, xeno-biology, UFO's are often dismissed out of hand because they don't fit the current paradigm of reality.

 

Justin,

Giant bugs are generally regarded as evidence of higher oxygen content in the coal age, but this can also be achieved by the same oxygen ratio that we have coupled with higher overall air pressure.

I believe it was a bit of both. Higher air pressure would help explain why the Earth was warm right up to the poles in those ages, then again higher CO2 and other greenhouse gases might explain that too.

Pterodactyls could not fly with current air pressure, even if the O2 levels were higher. I don't see any way around that problem. I have heard coastal winds offered as an explanation, but I don't buy it. They would not be consistent enough for these creatures to fly and feed as needed.

 

Regarding the kind of stuff in the website linked by Koryssa_Rus, all it would take would be two or more serious, scientifically trained researchers exploring the sites mentioned and taking the kind of rigorous notes and measurements needed, and publishing their results for peer review.

If there is no journal for those kinds of explorations, because of the paradigm problem, then there should be one. I wonder what it would take to start a journal of that sort...cuz somebody shuold do it, if it hasn't yet been done...

Atmospheric pressure

Could this also explain the human giants in stories told, or were they really in fact.. 'Giant Aliens' ..

 

Let's assume for the sake of argument that the stories of giant humans were true. From what I know of human (really all mammalian) respiratory systems and growth patterns, we don't keep getting bigger simply from the availability of more oxygen (or higher air pressure with same result).

But some insects do respond to greater air pressure/higher O2 by growing bigger. Their respiratory system is different and they can simply shed their exoskeleton and grow a bigger body if the air pressure allows it.

So why would there be larger humans? It is possible that genetic diversity was greater in those days and one aspect of that diversity might have been genes for giantism that do not exist in the present human genome.

If there was a time when those giant genes did exist, the genes might have been randomly concentrated in isolated groups of people and someone born with the full set of genes that are expressed in giant size would reach the proportions mentioned in old fables and holy books.

I would assume if you only had one gene for extreme tallness, it might result only in a person of average stature.

It is highly unlikely that a race of aliens had so close a genetic match to humans that they could interbreed with us. Only genetic engineering could have done that. While not ruling that out, it seems more likely that our genes are simply not as diverse (including genes for height) that humanity once had!

 

I saw a UFO with 2 of my other friends in a country town I grew up in. It flew over a cornfield then started to fly away from us until it disappeared. It was HAULING ASS.

 

That covers it, all righty. Fascinating article, too.

We still get an occasional giant here and there. Maybe nobody who's 5 meters tall, tho.

I'm still wondering if the so-called "aliens" could be time-travelling humans from milliions of years in the future. That would help explain why there have been so many sightings. Of course, if some distant race had technology that could whisk them here and back almost instantly, that could make the frequent visitations more feasible. However it would also make sense for future inhabitants of their ancestral planet to want to satisfy their curiosity about their ancestors and older civilizations.

I mean, if I could travel back in time to see what it was like in ancient Egypt or ancient Greece when their great architecture was still intact and to see what it was like for the people living there at the time - damn! That would be a dream vacation! Or being able to observe neanderthals and Homo erectus appearance, behavior, and society - uh huh, sign me up!
