One Strange Rock: A Must Watch

One Strange Rock 2018

One Strange Rock is a 10 part, 8 hour documentary produced in 2018 by Darren Aronofsky and hosted by Will Smith and 8 space station astronauts.

I’ve watched a lot of nature/science documentaries in my life, and I’ve probably seen most of the good ones, but I say without hesitation that One Strange Rock is the best.

The producers and writers found a magical blend of spectacular settings on and off the planet, fabulous photography, inspirational multi-cultural stories, solid yet easy to understand science, and an important ecological message that is neither depressing nor ignorant of our peril.

With regard to the history and science of Earth’s life, they hit most of the important points everyone should know, got none of them wrong, and missed only a few key points (not least of which the significance of reality denial 🙂 ).

The only segment I did not like was the bit on why we must and will colonize other planets. That’s wishful thinking (aka denial) and is not going to happen, but understandable because that’s their gig. Otherwise very well done!

With regard to beauty and inspiration, they hit a home run, without being sickly sweet. If you don’t feel some joyous emotion watching this, you’re not alive.

This should be mandatory viewing for every student on the planet.

If I ever meet someone in the future who doesn’t understand why they should care, I will point them to One Strange Rock.

If anyone would like to view this documentary but can’t find it, send me a message on Facebook and I will help you.

 

From award-winning filmmaker Darren Aronofsky comes a mind-bending, thrilling journey that explores the fragility and wonder of planet Earth—one of the most peculiar, unique places in the universe.

One Strange Rock is the extraordinary story of Earth – our curiously calibrated, interconnected planet – and why it is special and uniquely brimming with life among a largely unknown but harsh cosmic arena. Anchoring the series is an elite group of astronauts who see Earth’s bigger picture; they provide unique perspectives and relate personal memoirs of our planet seen from space.

Hosted by Will Smith, One Strange Rock reveals the twists of fate that allow life to thrive on Earth.

Part 1: Gasp

For those privileged few who have seen Earth from space, the very first thing they notice is the thin blue line of atmosphere that clings to our planet and sustains life. How our planet creates and regulates that oxygen is a mind-blowing story involving a flying river, a global dust storm, collapsing glaciers and the most important creature you’ve never heard of. It’s an incredible chain of connections that reveal just how truly wondrous our home is. Everything connects, so life and planet breathe together. Astronaut host – Chris Hadfield

Part 2: Storm

Ever wonder how our planet got here? It was born in a cosmic storm and shaped by violence. Earth is a very lucky planet. We’re only here because of random collisions in a dangerous cosmos. They could have destroyed us, but instead, that violence constructed a planet from the rubble of the early solar system; gave us oceans in a bombardment from the heavens; and brought order to our world. Astronaut host – Nicole Stott.

Part 3: Shield

It’s a David and Goliath story — Earth’s relationship with its greatest threat: our seemingly benign sun. Hurling devastating particles and deadly radiation at us, the sun is the big violent boss of the solar system. Without several shields, one generated by our unique planetary core, another by our atmosphere, and a third by our interconnected weather systems, life on Earth never would have survived. Astronaut host – Jeff Hoffman.

Part 4: Genesis

Our rock is special; it’s alive. Though the building blocks of life are common across the universe, life is rare. What is it about Earth that sets it apart? This is the story of dynamic forces and crazy coincidences that took a bunch of dead ingredients and transformed them into something as wondrously intricate as life. And if it happened here, could it happen elsewhere? Astronaut host – Mae Jemison.

Part 5: Survival

Without the cycle of death and sacrifice, from cellular to planetary, life would not be here. From the deaths of stars to planetary scale mass extinctions and the sacrifice of individuals for a greater genetic good, this is the story of how life evolved hand in hand with death. Death drives evolution. It’s hardwired; from our cells to our landscapes, our colorful living planet is only possible thanks to it. Death leads to opportunity and biodiversity, which ironically ensures life on the planet is never wiped out. It’s not enough for our planet to be habitable; it also has to be lethal. Astronaut host – Jerry Linenger.

Part 6: Escape

Is it possible for intelligent life to escape destruction either from the planet or ourselves? Or are we destined for extinction like 99.9 percent of all species before us? Our best chance of survival may be to escape Earth and build another colony somewhere else. But there are real barriers: space radiation, microgravity and the bacteria inside us. And our DNA is coded for the conditions here on Earth, so if we ever manage to colonize another planet, those who are born there might evolve into another species. Astronaut host – Chris Hadfield.

Part 7: Terraform

Ever since life emerged, microbes, plants and animals have all sculpted the planet’s surface and atmosphere in the strangest of ways: fish poop creates islands; dead animals create mountains; and plants help create continents. From rocks to rivers, life has crafted everything that makes our planet so special. But this power of change brings with it profound dangers. Life doesn’t just create. It can also destroy. Astronaut host – Mike Massimino.

Part 8: Alien

All life on Earth started as single-cell bacteria and stayed like that for two billion years. So even if we do find alien life out there, what are the chances of that life being complex like us? On our strange rock, it’s all down to a freak event, which accidentally happened when one cell ate another to create a kind of power pack for life. This almost miraculous event transforms Earth into a complex interconnected web based on a competition for food. And at the top of the pyramid sit we humans. Astronaut host – Mae Jemison.

Part 9: Awakening

Of all life on Earth, how come we’re the only ones with the smarts to leave our planet? For three billion years, nothing had a brain. Even today, over 90 percent of life doesn’t need a brain to survive. So, what happened? How did our planet set in motion the chain of nearly impossible events that gave us our unique intelligence? The greatest mystery of all may be right between your ears. Astronaut host – Leland Melvin.

Part 10: Home

After 665 weightless days in space, NASA’s most experienced astronaut, Peggy Whitson, smashes through the atmosphere on her last journey home to planet Earth. With unprecedented filming on board the ISS during Peggy’s final mission and with the support of our other featured astronauts, we reveal how their time in space transforms their understanding of our planet’s wonders, insights that will change our perspective, too. There is no place like home. Or is there? Just how strange is our rock, and is it really unique in the universe? Astronaut host – Peggy Whitson.

 

By Tad Patzek: On Human Overshoot

Tad Patzek

Tad Patzek, a professor of petroleum engineering and physicist, gave a talk on January 16, 2019 at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia.

His talk is titled “How Can We Salvage Our Global Civilization?” however Patzek does not answer his own question. Instead he reviews the brief history of humans and shows that we are in a severe state of overshoot with a population that exceeds the carrying capacity of the planet by about 30 times thanks to fossil energy, which he predicts will soon rapidly decline due to depletion. In the Q&A that follows the talk, Patzek advocates for population reduction policies. Also in the Q&A, Patzek gets quite aggressive with audience members who argue that technology will save us. He concludes that we will probably use nuclear war to correct overshoot. I wonder if he’ll be invited back next year? 🙂

You can find other work I’ve posted by Patzek here.

Thanks to Nate Hagens for bringing this talk to my attention.

 

 

Here are some notes I took while viewing the talk:

  • Continued exponential growth of human population is suicidal and will stop one way or another.
  • Humans have only one chance of survival by drastically limiting population and consumption.
  • Patzek quotes from Ronald Wright’s A Short History of Progress, my all-time favorite lecture series, to make the point that humans, the fire apes, have been setting fires continuously from our origin until today when many of the world’s tropical forests are being burned to make way for agriculture and plantations.
  • Patzek does a nice job of explaining that humans have existed for an extremely short period in the context of geologic time. For example, if we call January 1 the start of the Silurian period 444 million years ago when multicellular life first appeared on land, then behaviorally modern humans emerged 70 minutes before midnight on December 31, our first civilization began 9 minutes before midnight, and the industrial civilization we currently enjoy began 20 seconds before midnight. The explosion of human population to 8 billion began 7 seconds before midnight on December 31, and was enabled by the Haber Bosch industrial process that converts natural gas into nitrogen fertilizer.
  • At 3 seconds before midnight on December 31, half of the US’s top soil had been washed into the sea, having taken only 9 seconds to accomplish this feat.
  • For an example of what 10,000 years of agriculture does to the earth, look at Iraq with its complete environmental devastation.
  • We only have one shot at the global civilization, and it shall never be repeated again.
  • Sending colonies to Mars is complete nonsense because there are not enough resources to send them.
  • None of our overshoot issues are captured by our economic models.
  • Our planet can support a maximum of 8 million humans making a living as hunter gatherers.
  • The earth might support 2.5 billion people assuming an 1800’s equivalent life expectancy (32 years) , lifestyle, slavery, and conflict. If we assume today’s life expectancy (71 years) the maximum drops to 1.1 billion people. Adjusting for our increased standard of living decreases the maximum to 500 million people. If we assume a peaceful life without wars the maximum sustainable population drops to 250 million people. This means we have overshot by the 30 times the carrying capacity of the planet by using fossil fuel subsidies.
  • Later in the Q&A, Patzek clarifies that if we assume an American or German lifestyle, the maximum sustainable population is 90 million without fossil energy.
  • I note that Patzek’s estimate of the maximum sustainable population aligns nicely with Jack Alpert’s plan to preserve our modern civilization with rapid population reduction.
  • Patzek shows that population is proportional to power production. Recall that Tim Garrett has also shown that wealth is proportional to power production. Energy is therefore central to our predicament as Nate Hagens elaborates in his video course.

By Irv Mills: My Peak Oil Journey

Irv Mills

Irv Mills today published a very nice history of peak oil in which he summarizes what has occurred to date, and explains how his understanding of the relationship between energy and the economy has evolved and improved over time.

Mills’ essay is clear, accurate, and accessible. I recommend it as an excellent primer on peak oil.

Mills observes that oil consumption in recent years has grown about 1.7% per year despite little or no real growth in the economy. He speculates that the extra energy is being consumed by the oil industry to produce oil that is now hard, and getting harder, to extract. I suspect he’s right and recently wrote about this red queen phenomenon here.

Mills sees economic problems in our future but also expects some surprises. I agree. As readers know, I am fascinated by the fact that we collectively deny the reality of peak oil, despite it being, by far, the most serious short-term threat to civilization. My hunch is that we will never accept the reality of peak oil. Something else will happen that we can blame for our economic woes. Like war. To admit that growth is over due to nature being more powerful than our hubris, and that we totally screwed up by ignoring obvious facts, is a pill too big to swallow for our egos.

https://theeasiestpersontofool.blogspot.com/2018/06/autobiographical-notes-part-4-my-peak.html

As that average EROEI declines toward about 15, economic growth grinds to a halt and it becomes difficult to raise capital to start new ventures and to maintain existing infrastructure. Below 15 a modern industrial civilization quits working. Because this is a weighted average, choosing to produce more energy from low EROEI sources makes things worse while temporarily seeming to make them better. It has been estimated that the current average EROEI of the world economy is around 11. Of course some lucky countries are doing much better than that.

But because of our “lowest hanging fruit first” approach, EROEI continues to decline. Real economic growth appears to have stopped in the 1990s, with governments using clever new ways of calculating gross domestic product, and unemployment and cost of living statistics to make things look better in the short run. And low interest rate policies to encourage lots of borrowing and keep the economy growing, again, in the short run.

 

The major oil companies were hurt by low prices too, and cut back on their investment on discovery in order to save money. This has left us in a very bad situation as far as oil supply goes over the next few years. Trillions of dollars would have to be spent on discovery to catch up with demand. It seems to some of us that there is no sweet spot where oil prices are low enough to keep the economy growing and high enough to make the oil business profitable.

In any case, it seems unlikely that there are actually sufficient oil resources out there even if we could find the money to spend on discovery.

By Sam Harris & Bart Ehrman: What Is Christianity?

 

Fascinating discussion, especially when viewed through the lens of Varki’s MORT theory which says the uniquely powerful human brain exists because it evolved an ability to deny mortality.

https://samharris.org/podcasts/what-is-christianity/

In this episode of the Waking Up podcast, Sam Harris speaks to Bart Ehrman about his experience of being a born-again Christian, his academic training in New Testament scholarship, his loss of faith, the most convincing argument in defense of Christianity, the status of miracles, the composition of the New Testament, the resurrection of Jesus, the nature of heaven and hell, the book of Revelation, the End Times, self-contradictions in the Bible, the concept of a messiah, whether Jesus actually existed, Christianity as a cult of human sacrifice, the conversion of Constantine, and other topics.

Bart D. Ehrman is the author or editor of more than thirty books, including the New York Times bestsellers Misquoting Jesus and How Jesus Became God. Ehrman is a professor of religious studies at the University of North Carolina, Chapel Hill, and a leading authority on the New Testament and the history of early Christianity. He has been featured in Time, The New Yorker, and The Washington Post, and has appeared on NBC, CNN, The Daily Show with Jon Stewart, The History Channel, National Geographic, BBC, major NPR shows, and other top print and broadcast media outlets. His most recent book is The Triumph of Christianity.

 

By Nate Hagens: Contrasts and Continuums of the Human Predicament

Here is this year’s annual Earth Day talk by Nate Hagens.

My introduction to last year’s talk by Nate is still valid:

I used to preface Nate’s talks by saying he provides the best big picture view of our predicament available anywhere.

While still true, I think Nate may now be the only person discussing these issues in public forums.

Everyone else seems to have retired to their bunkers and gone quiet.

If you only have an hour this year to devote to understanding the human predicament and what needs to be done, this may be the best way to spend it.

 

On Apollo: The Most Impressive Human Achievement

How Apollo Flew to the Moon

I’m an electrical engineer that specialized in operating system design. I built my first computer in 1981 before the IBM PC was available. I designed an integrated circuit in 1983 for my Masters thesis. I managed large R&D groups for most of my 25 year career. I continue to be a technology geek in my personal life. As a consequence, I have a pretty good sense of what is impressive, and what is not, from an engineering perspective.

As readers probably know, I think net energy constraints have placed us at, or passed, the peak of all forms of complexity, including technology. I see evidence everywhere of peak technology.

The highlights of human engineering accomplishments for me include: steel, concrete, glass, Haber-Bosch fertilizer, diesel engines, turbine engines, turbine electricity generators, electric motors, electromagnetic communications, hydraulics, heat pumps, Panama canal, Golden Gate bridge, Chunnel, Concorde, Apollo, Hubble, Voyager, nuclear submarines, skyscrapers, deep-sea oil rigs, integrated circuits, microprocessors, magnetic storage, lasers, LED lights, internet, lithium-ion batteries, robotics, and DNA sequencing.

Notice that everything on this list is over 20 years old.  I can’t think of anything of equal importance that was invented in the last 20 years.

Gasoline and turbine engine efficiency gains have stalled. Diesel engine efficiency is going backwards due to new pollution regulations. Air travel speed plateaued many years ago.  The promise of too cheap to meter nuclear electricity appears certain to remain a dream. Battery performance barely creeps forward despite a hundred years of promises. My 3 year old smart phone works fine with no compelling reason to upgrade. Cameras were good enough many years ago. Household appliances are getting smarter, but their core functions are not improving, and they don’t last as long due to cost reduction pressures. TV resolution is increasing but few need it. LED lights are getting cheaper, but the technology was invented many years ago. Popular Mechanics magazine no longer writes about jet packs and flying cars.

It’s been 6 years since I built my current desktop computer. There’s still no compelling reason to upgrade it. If I spend the thousand dollars required to upgrade it, I will gain 25% performance. That’s nothing compared to the gains we saw 20 years ago.

I can see how a non-engineer might think otherwise. A computer in your pocket with a wireless connection to the internet feels like magic, but advances in the technologies used to build smart phones began to level off years ago. It’s not advances in fundamental technology that’s creating today’s magic. It’s thousands of small innovative apps, plus a few monster apps that leverage a 25 year old internet to connect us with friends and businesses, that creates the illusion of magic. Apps are software, and software is not new. There’s just a lot more software variety available to supply a much larger market created by everyone having a networked computer camera in their pocket.

For a long time I’ve felt our most impressive technology accomplishment occurred 50 years ago when we visited the moon. I vividly remember as an 11 year boy going outside at night and looking up in awe at Armstrong on the moon.

Over the years I’ve read and watched much about the Apollo program but never encountered anything that got into the details of Apollo’s engineering. I intuitively suspected there was a lot of impressive technology depth to Apollo, but never had the facts to back up my intuition.

I’ve just finished the book How Apollo Flew to the Moon by W. David Woods and now I have the facts to confirm my intuition. The book covers all of the technical details for every phase of the mission from launch to splashdown. I love the clear, concise, and engaging writing style of the author.

What those 400,000 people 50 years ago accomplished over 10 years is breath-taking. Every step of the mission involved staggering engineering challenges and trade-offs.  Lives were at stake on prime time television. The scale is hard to fathom. For example, the power produced by the Saturn V first stage was equivalent to the entire electricity consumption of the UK. More recent engineering accomplishments are not even in the same league.

Wood’s book answered all of my questions plus many I had not thought of:

  • how did the engines work?
  • how did they navigate?
  • how did they steer?
  • how did the stages separate?
  • how do you move from an earth orbit to a lunar orbit and back?
  • how did the lunar module land?
  • how did the lunar module take off, find, and rendezvous with the command module?
  • how did mission control track location and monitor systems?
  • what did the computers do?
  • what were the emergency contingency plans?

If you prefer to listen than read, here are some excellent podcasts with W. David Woods discussing the Apollo program:

Omega Tau 083 – How Apollo Flew to the Moon (December 15, 2011)

Omega Tau 097 – How Apollo Explored the Moon (June 18, 2012)

Omega Tau 176 – The Gemini Programme (July 18, 2015)

Omega Tau 239 – The Saturn V Launch Vehicle (March 12, 2017)

If you prefer to watch than read, here is a video presentation by W. David Woods in which the production quality is mediocre, but the content is strong.

 

If you are wondering why we have not accomplished anything even close to the Apollo program in the intervening 50 years, it’s because per capita net energy peaked around 1970, and has been declining ever since. In other words, our most complex achievement coincided with the peak of per capita net energy, as students of thermodynamics should expect.

I predict that the Apollo program will remain in perpetuity the most impressive achievement of the human species.
