Carl Sagan Keynote Speech at Emerging Issues Forum

Dr. Sagan's 2/9/1990 address at the 5th Emerging Issues Forum at NCSU, broadcast live on NC Public TV. Sagan spoke at the invitation of former Gov. Jim Hunt, co-creator of the Forum. Speech starts at 6:22.
Sagan expounds on climate observations and energy strategies for a sustainable future, emphasizing solar. His speech was referenced in my 1990 student radio interviews with Gregg Maryniak and Chris Faranetta of the Space Studies Institute (SSI) and Dr. George A. (Jay) Keyworth II, former Reagan Science Advisor, on the subject of space solar power (SSP).
The SSP story:
Princeton physicist Gerard K. O'Neill joined with Dr. Peter E. Glaser of A.D. Little Corp. and Raytheon engineer William C. Brown in the 1970s-80s to solve the seemingly diametric problems of massive 21st century energy requirements and planetary preservation for a plan that would start up an ambitious off-Earth enterprise for America and partners.
NASA and the Dept. of Energy released a joint study "Satellite Power System Concept Development and Evaluation Program Assessment Report" in 1980. NASA and DOE found a technical case for SSP but no financial case assuming materials launched 100% from the ground.
SSP concepts have improved. Launch alternatives have multiplied as costs decline. PVs, robotics, AI, and 3D printing have improved. The discovery of water ice at the lunar poles in 2009 aids the case for using lunar materials, a rationale introduced by SSI, whose study in the mid-1980s found a 97% cost-savings by using the Moon.
The sunsat was invented by Glaser in 1968, based on Brown's microwave wireless power transfer demonstrations in 1964. The O'Neill-Glaser-Brown vision called for partnerships to expand economic activity on the High Frontier, including sunsat manufacture via lunar surface machines and free-space processing infrastructure. NEOs would be captured for additional materials and fuels, meeting planetary defense requirements.
SSP would scale to meet a potential $10 trillion market for new and replacement electric generating stations, extend the life of coal, oil & gas, end the nuclear stopgap, provide inexhaustible clean energy to the nations, charge electric vehicles, and deliver instant secure power to disaster zones and forward military operations.
The activity would allay Dr. Sagan's concerns, here so eloquently expressed, over CO2 greenhouse warming and the problem of nuclear waste disposal.
SSP would be the business backbone of space settlement. Dr. O'Neill's rotating habitats in free space, built also from lunar materials and powered by the sun, would facilitate the growth of industry and species to a potential many times the current population. SSP workers and others would live in 1g environments in shielded sunlit cylindrical real estate in Lagrangian orbits known to be stable. These inverted biospheres would be in part cities for the workers, part industry & agriculture, part university, part water & wilderness, and part sports/recreation & tourism destinations. Travel and trade between facilities and Earth would be a relatively low energy-cost affair with minimal communications delays.
Jeff Bezos, a proponent of the O'Neill-Glaser-Brown vision, announced in 2019 www.blueorigin.com/news/going... that his company Blue Origin is working to make the access infrastructure a reality. Solar Power Satellites were referenced in a slide graphic at the event. SSP and NASA's lunar return program, Artemis, are supported by the National Space Society space.nss.org/. SpaceX www.spacex.com and Blue Origin are selected to build landers for Artemis.
SSP leadership has competition in the world. Players include China www.smh.com.au/world/asia/pla..., Japan, India, Russia, and nations in Europe, who are pursuing their own R&D. A smart path forward for standards and cost-sharing may be an international consortium of interested public and private partners led by the country of its origin, the United States.
A compendium of research and conference proceedings on the topics of solar power satellites and space manufacturing is housed at ssi.org, the website for the nonprofit Space Studies Institute founded in 1977 by the late Gerard O'Neill.
"...I would put it (SSP) amongst any list of serious contenders for new energy technologies…. I think the lunar infrastructure that Gerry O’Neill talks about (for materials extraction) is well thought out.” - Jay Keyworth, 1990 face to face interview
"Our technology is capable of extraordinary new ventures in space, one of which Gerard O'Neill has described to you.... It is practical." - Carl Sagan, book blurb, The High Frontier (1989 edition) by G K O'Neill.
“The sun doesn’t run out, or at least not for 5 billion years, and I figure that’s good enough.” - Carl Sagan 1:00:40

    I can't agree. It was always our burden. He couldn't protect the world alone and he was never aspiring to do it. But he taught us how to do it. He prepared us. It's the same as with me and my fiance. All people around thought she's making me happy and they were sure it will go away if she would be gone one day. They all couldn't grasp an idea that what she did was showing me how to be happy, so I could be happy anywhere - not as a conditional, temporary deal. They gave me an idea of how to do it myself. They weren't a fire, but they lighted it - and that's what makes them differ from a lot of protectors or people we enjoy. They are both gone, but it was always up to me (or us, in case of Sagan) to keep that fire. What we can do now is not just protect the world. We should light that fire in others. We will be gone in a moment - years or decades. But the struggle must continue. They gave us something wonderful - and let's not trivialize it.

    ‏Anthony Flew is considered one of the most prominent atheists, so he retracted his atheism and ،told us that the universe has a deity with modern scientific evidence, not with thought or dreams and feeling, but after science and modern discoveries about the existence of a Creator. He fell into another problem that the Creator wanted according to his mood ‏ He wanted the Creator to be neither speaking nor hearing, and creating creation in vain ‏But it is logical that this Creator sends a messenger to teach us who he is. And we have to verify the authenticity of the Messenger and what this Messenger calls to? ‏ It transports sperm from the liquid state to the eyes, heart, blood, arteries, and bones. Unconscious nature creates a conscious human being. Then this nature teaches about the importance of the heart and lung, then puts the rib cage, then oxygen, then water, there is sexual desire, and there are the genitals to complete the male and female sexual process. , What coincidence are you talking about, a coincidence that creates the male and the female. All of these are called verses and there are things that complement each other, there is a lung and there is air and there are teeth and stomach and in food and other things and we say that it has no creator!!! ‏ The only question God will ask you is ‏ focus on it ‏ ((He said: Did you deny My verses and did not encompass them in knowledge, or what did you do?)) ‏ I mean, God Almighty tells you what I told you is a lie and you cannot realize it or understand it ‏ And what in the world have you been doing? ‏ Do you know what your answer is? ‏ ((The decree will befall them for what they did wrong, and they will not be able to speak. ‏ If you find yourself in the world without a choice in a great reality we live in, and you go without a choice and a question is the most important ‏ If your destiny is fire, has God wronged you???ًً ‏Muhammad, may God’s prayers and peace be upon him, is a prophet from the Creator, and before him many prophets did not lie or deceive, and he is the only religion that commands you to worship one Creator who created everything. ‏First of all, you should know that the religion of all prophets is the worship of one Creator who created everything. Islam today is the only religion that commands you to worship one Creator and not idols, illusions, conjecture or a number of gods. But how do we know that the speech is from God and not from Muhammad, may God bless him and grant him peace? . These are some of the things that comfort your heart and believe that this is a prophet and many of the prophets before him ‏ The Almighty said: (Moreover He comprehended in His design the sky, and it had been (as) smoke) ‏ The smoke confirms that the origin of this universe is inflamed. It is not a lake of water, as was the perception of all philosophies and religions that are based on illusion. This is one of the postulates of modern science today that the sky is condensation of smoke. This fact converted the French scientist Maurice to Islam and wrote a book entitled the Holy Qur’an on the scale of modern science ‏How did Muhammad, may God bless him and grant him peace, know this fact before? ‏ The Almighty says: ((And the heaven We constructed)) ‏ The sky is a building, not a vacuum as it was thought, and this was awarded the Nobel Prize in Physics in 2017 that proved it ‏How did Muhammad, may God bless him and grant him peace, know this fact before? ‏The Almighty’s saying: ((And the heaven We constructed with strength, and indeed, We are [its] expander. )). ‏ That is, the sky expands with time. This fact, even in the time of Einstein, was not imagined by anyone and it was proven. And Einstein admitted it and admitted that it was the biggest scientific mistake he made in his life if he believed that the sky was fixed. The Qur’an before Einstein says that the sky expands ‏fact ‏ Almighty’s saying: :((And We have made the night and day two signs, and We erased the sign of the night and made the sign of the day visible that you may seek bounty from your Lord and may know the number of years and the account [of time]. And everything We have set out in detail. )) ‏ The verse of the night is the moon and the verse of the day is the sun. The Qur'an tells that the sun and the moon were fiery masses. That is, the moon was a fiery mass and was erased, and the verse of the day remained visible to the eyes. Was the moon a fiery mass and extinguished? This is one of the biggest scientific issues discovered about the moon. The moon was already a fiery mass, and NASA issued on its official website a conceptual clip entitled The Evolution of the Moon in the video. In fact, the moon was a fiery mass like the sun, and this is what the Qur’an told about and the truth of modern science. ‏How did Muhammad, may God bless him and grant him peace, know this fact before? ‏Almighty’s saying ‏And you see the mountains thinking that they are rigid, while you will cross as the passage of clouds. [It is] the work of God who has perfected everything. In fact, he knows what you're doing.)) ‏ And the verse clearly spoke of a strange phenomenon, which is that the viewer of the mountains appears to him still, that is, they are still, but in fact they are not like that, rather they are in a state of constant movement. And the infidels of Quraish had previously accused our master Muhammad, may God’s prayers and peace be upon him, of madness, and it is likely that their joy was overwhelming when this verse was revealed. ‏ They also found in it, according to their claim, evidence of this madness, and they told the people: How can you believe this man who says that these fixed mountains move like clouds moving in the sky! ‏ And today it is proven that the earth rotates, and with it the mountains, how did Muhammad know that and why is he telling you instead of the matter that makes people consider him crazy? The matter was not from him, but from God. Almighty’s saying ‏Those whom Allah (in His plan) willeth to guide,- He openeth their breast to Islam; those whom He willeth to leave straying,- He maketh their breast close and constricted, as if they had to climb up to the skies: thus doth Allah (heap) the penalty on those who refuse to believe)). ‏After man was able to reach the sky by flying by modern means of transportation, he knew that the higher up in the air, the less oxygen and atmospheric pressure, which causes severe tightness in the chests and the process of breathing. : ‏How did Muhammad, may God bless him and grant him peace, know this fact before? It was not from him, but from God Almighty’s saying ‏Or (the Unbelievers' state) is like the depths of darkness in a vast deep ocean, overwhelmed with billow topped by billow, topped by (dark) clouds: depths of darkness, one above another: if a man stretches out his hands, he can hardly see it! for any to whom Allah giveth not light, there is no light! ‏Modern sciences have revealed that in the bottom of the deep seas with abundant water - the deep sea - there is great darkness, to the extent that living creatures live in this darkness without visual tools, but live using their other senses such as hearing. ‏These dark darknesses are not found in the sea water that surrounds the Arabian Peninsula, but rather they have been discovered in the oceans far from it ‏This verse shows another aspect of the Qur’anic miracle, which is that the sea wave that all people only knew was one wave in the seas ‏The verse says there is another wave in the depths of the sea, and divers discovered at the beginning of the twentieth century a fact that was hidden in the depths of the sea, that fact that shows another wave that throws divers into it as it is thrown at swimmers, and this wave was discovered by Scandinavian divers. I will tell you what the Prophet said. The Prophet, may God bless him and grant him peace, said: One day the Bedouins who live in the desert will build tall towers, and this is my duty. Go and see where the tallest buildings are and who owns them. ‏God Almighty: ((We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth. But is it not sufficient concerning your Lord that He is, over all things, a Witness?) And God informed the Qur’an of this by saying: “Did you think that we created you without a purpose and that you would never return to us?” ‏All these and other matters that I have not mentioned indicate that this is a prophet from God..More important than that, as I told you, is the only religion that commands you to worship one Creator, who created everything and before him many prophets. ‏Say, if you wish, there is no god but God, and that Muhammad is the Messenger of God ‏ speak from the heart ًًًً

It is clear creation had to be done supernaturally yet it is still denied because people are just too proud to accept that, among other things.

    For those pro or con on AGW, this speech was referenced on a student radio project in 1990 that included a face-to-face interview with the conservative Dr. George A. (Jay) Keyworth II, former Reagan Science Advisor and former Director of the Physics Division at Los Alamos National Laboratory. Keyworth was Reagan's SDI defender, a concept that helped end the Cold War. The project was on the subject of space solar power (SSP), more commonly known today as space-based solar power (SBSP), an industry that we now know can grow the global GDP tenfold while solving the energy/climate problem on the ground permanently. The descriptive notes on this video post lay it out. Thanks to Keyworth, who was a friend of Dr. Gerard K. O'Neill of Princeton physics and the Space Studies Institute, Reagan and GHW Bush became fans of SBSP and O'Neill's ideas on space manufacturing & settlement, which he proposed as an outgrowth of the SBSP industry. O'Neill served on Reagan's National Commission on Space, whose report "Pioneering the Space Frontier", was released in July, 1986. The noted liberal Carl Sagan backed O'Neill in 1975 congressional testimony. Every problem generates a solution, if we admit the problem. If policymakers continue to deny the AGW problem, and misdirect investments, we will shortchange history and species.

    Point is : Scientists warned us for global warming and greenhouse-effects over 40 years ago. It's been an issue for over 40 years, only not the first point on the agenda. Acid rain was tackled by extracting sulfur out of crude-oil and its derivates an by catalytic convertors. CFC were banned and alternatives were found. However, those solutions did not (really) affect our daily lives. The issues we're facing now force us to change our daily routines. And that's something humans are inherently bad at. I'm certainly not saying that I'm good at it, only human after all. But it all starts by acknowledging there IS a problem.

    No. They refuse to participate, for good reason. It’s very sad but the only option now is to wait until they fail and the world is collapsing then take it back and make it right. I believe the current world leaders in politics and business know absolutely for a fact that the world is heading for disaster, they’re going to take as much as they can until it does because they’re extremely afraid of what will happen to them once the truth is extremely obvious to the general population. They want to have all the wealth and power when that happens. It will happen. The question is when. CO2 levels have not even slowed down btw they’re only increasing, which is why they say now that it’s a “natural process” that humans don’t impact when we knew for a fact at the time of this speech that humanity contributed immensely to the rise in greenhouse gases. They are only protecting themselves for the impending catastrophe that they know is now inevitable and they’re not willing to risk their wealth and power to try to fix it because the efforts made so far have done nothing significant so it seems hopeless to them, might as well consolidate power and wealth until it happens. Both of which are very evident, as the rich continue to get richer and the world continues to warm. They’re also steadily working towards disarming the public for the same reasons. Many millions will die once harvests begin to fail, they don’t want to be one of them, do you? What are you gonna do about it? They’re preparing, why aren’t we?

    The IPCC report released 3/20/23 found that the target limiting warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial temps within a decade is not likely to be met. The National Space Council and ARPA-E should be looking hard at Space-based Solar Power right now to meet terrestrial energy needs and net zero emissions targets by 2050. The DOE should be seated on the National Space Council. Agencies in other nations like China, India, Japan, UK, and the EU are currently investing in SBSP programs. NASA's Artemis program, Starship HLS, Blue Moon HLS, other private systems, and companies who will manufacture (or print) from both Earth-sourced and lunar-sourced materials, will help bring SBSP to a competitive business case. With focus, motivation, and government risk mitigation, timelines can be reduced. The PRC has stated intentions to use their Tiangong space station for power beaming tests and the moon for sunsat construction materials. Resources preserved in shadowed craters at the lunar poles (like water and other useful volatiles) will be game-changing for their SBSP program, they project. The solar power satellite was invented in the U.S. in 1968. The potential market for the industry is $10 trillion per year by 2050. Along with other ground-based measures, it can meet the energy and environmental requirements for our expanding civilization for the duration of the sun. "With so large a potential market, we in the United States must move aggressively to regain a leading role in (SBSP's) development. Above all, we who live in the biosphere cannot afford to let it die." - Prof. Gerard K. O'Neill, Alternative Plan for US National Space Program,1990, Space Studies Institute “The sun doesn’t run out, or at least not for 5 billion years, and I figure that’s good enough.” - Carl Sagan, 2/9/1990 speech before the 5th Emerging Issues Forum, NCSU

    Absolutely amazing speech ... unbelievable, that these forecasts from 20 years ago do correspond 1:1 to the observations of our generation. As a guy of science, I believe to be able to distinguisch between people who just talk and those who really have to say something. Thanks Carl, rip, this was inspriring.

    What a great sadness that we should lose a man of such stature at a time we so desperately need men of vision

    Great speech. I think, judging by his closing remark, he would be dismayed by what has happened up to now.
