• en Oxygen: The terraforming of Earth

  • (Picture by Alexander Gerst from the ISS)

    We take good old O2 for granted. People are always going on about how early Earth was “perfect” for life. A perfect hell maybe. No ozone layer, no oxygen, extreme heat, an abundance of highly corrosive chemicals in the atmosphere including sulfur and methane.

    Much like found on Titan the largest of the moons of Jupiter today. It was a literal red sky hell. With all of that methane and sulfur, it must have smelled like a frat house on chili and hard boiled egg night. So, the Earth was devoid of oxygen in the beginning but as I said there was a metric butt-load of methane and sulfur in the oceans.

    So, little single-celled organisms developed that lived on methane and sulfur. After a while, the sulfur level dropped and the methane level did as well. No one is sure why. There still was little oxygen. So some more little critters evolved which produced oxygen called “cyanobacteria”.

    It took a billion years for these critters to terraform our planet for the evolution of animals and more complex plants. To this day all plants incorporate these ancient cyanobacteria into their cells in structures known as a “cyanoplasts”. You see life itself changed the planet to support life.

    This is what life does.

    it reminds me of Fermi paradox. existence itself seems like a miracle 

    on April 22, 2019

    No miracle in my opinion. Life on Earth just only started at the right time of the universe, a million years earlier or later it would not be possible due of the events occuring in the universe.

    Also I have my own doubts regarding the Fermi paradox though I really wish that there is somewhere extraterrestrial life forms i.e. “aliens just waiting to be found.

  • en DNA: Life’s Changelog

  • One of the most interesting things about DNA is that we have discovered, in humans, the 3% of the code which builds our physical bodies also has encoded within the bodies of all of our ancestors. We can switch on these old systems (in animals of course since this would be highly unethical to do to human beings) and give a chicken teeth or scales. We are not just us. We are all the physical forms in our lineage.

    Now, that accounts for 3% of our storage. What of the other 97%? It is memories. Now the skeptic will go “yeah right Mr. Science”. Hear me out here though. Why is it so hard to accept memories encoded into the helix? In fact all “instinct” is encoded memory. What beach to lay your eggs by the light of the full moon if you are a tortoise. Where to migrate if you are a starling or a monarch butterfly. Sharks even have maps of the magnetic markers on the seafloor. None of this is learned. It is there at birth.

    There is a very good evolutionary reason for this. Rapid adaptation. We have a repository of past experiences so we do not have to reinvent the wheel every time our environment changes. Human beings have noted this for at least as long as we have records and this has given rise to theories of reincarnation which appeared in nearly every civilization on Earth. Science has resisted this because it sounds too “supernatural” in the same way they resisted the “Big Bang” because it sounded too much like creation. Yet, it is anything but supernatural. It is entirely natural and the only explanation which makes any sense.

    I think our ancestors felt it by through the mind. I see it from Ojibwe and more ancient cultures

    on April 8, 2019

    I think you are right. DNA is essentially a memory recording code. Our memories are written into the code using the epigenetic genome. Only 3% of our DNA is used for building our bodies. The rest is a combination of genetic modules which can be switched on and off as our environment changes and, far more, is recorded memory. Here is the world changing part. The memories are not just ours. They are those of our anscestors. Your “self” and your physical body are simply disposable shells. The gene is the true being and it is immortal. Within it are the inherited memories of a thousand thousand generations. All of your ancestors live in the gene and that is how life works.

  • Always think for yourself …

  • We live in a time when many people are losing faith in the traditional Gods but mankind seems to have a desperate need for worship. So, we worship celebrities. Movie stars. Royalty. Athletes. Fake preachers and gurus. Yet they too let us down. They get caught in a scandal, they say something inappropriate when they are drunk, beat their wives. They bilk the trusting and are caught.

    Then the false gods plummet to the Earth.

    You see, just as we are fond of setting up false idols to worship so are we keen on seeing them fall. Never worship human beings. Human beings are frail and worship often tears them apart. They will fail you. They will always fail you.

    Always think for yourself.

    “Believe nothing merely because you have been told it. Do not believe what your teacher tells you merely out of respect for the teacher. But whatsoever, after due examination and analysis, you find to be kind, conducive to the good, the benefit, the welfare of all beings – that doctrine believe and cling to, and take it as your guide.”

    ~ Siddhartha Gautama, the Buddha, from The Kalama Sutta

    Critical thinking is an important skill. 😉 Especially nowadays since we get “bombed” with tons of news on a regular basis.

    thinking, acting, and learning seem to have their own cycles to me

    on March 17, 2019

    I feel some of thinking and learning grow themselves without me. and they visit me sometimes. 

    on March 16, 2019

    I think everyone has their own way in thinking, acting, and learning and that’s good as it is. It adds diversity to just everything, in jobs or simple conversations.
