This 1,992 paper was included on best-selling CDR World Philosophy compilation (before internet) and I claim some credit for circulated it and popularising the “Transhuman sidetrack”

Since 1,988 and formation of the Posthuman Movement, and articles by early adopters like Max Moore were a sign our message was being received — although I always argued on various Extropian & Transhuman bulletin boards & Yahoo groups &c that “Trans” was a redundant middle and we should move straight to Posthuman, now armed with the new MVT knowledge (also figures on the CDR). There will be a new edition of World Philosophy, the first this millennium, to coincided with various Posthuman University events later this year. Here is the text:

THE EXTROPIAN PRINCIPLES V. 2.01 August 7 1992.

Scientists find origin of asteroid that killed the dinosaurs

Posted by in categories: asteroid/comet impacts, existential risks

Astronomers believe that they have discovered the origin of the asteroid that wiped out the dinosaurs.

The six mile-wide asteroid which struck the Earth 66 million years ago and ended the 180 million year-long reign of the dinosaurs, was the cause of what is known as a Chicxulub events. It landed in what is now the Yucatan peninsula in Mexico and formed the Chicxulub crater.

Scientists had examined the remains of the ancient rock through the samples on the Earth and within drill cores, which revealed that the debris came from a carbonaceous chondrite class of meteorites – some of the most pristine material in the entire solar system.

*Astronomers zero in on source of the impactor that wiped out the dinosaurs.
A new study claims the impactor believed to have wiped out and 75 percent of all life on Earth 66 million years ago including all the non-avian dinosaurs — likely came from the outer half of the main asteroid belt between Mars and Jupiter.
*Producing matter out of pure energy.
Scientists have directly converted pure light energy into matter in a single process for the first time.
The findings reported in the journal Physical Review Letters involved the creation of Electrons and their antimatter counter parts positrons — by colliding quantum packets of photons – light particles.
*Discovery of a galactic stream of galaxy clusters.
Astronomers have discovered a never-before-seen galaxy cluster with a black hole at its centre, travelling at high speed along an intergalactic road of matter.

NBD, There’s Just a Massive Asteroid Hurtling Past Earth This Month

Posted by in categories: asteroid/comet impacts, existential risks

Should you be worried about the massive space rock that could, theoretically, spell disaster if it were to make landfall on terra firma? No, you shouldn’t. But that doesn’t mean you should ignore it either.

The asteroid, called 2016 AJ193, is just under a mile wide and moving at a speed of 58538 miles per hour, according to EarthSky. Its closest encounter with Earth will occur on August 23 at 11:10 a.m. ET, and experts note that anyone trying to spot the asteroid in the wild will have the best chance of doing so before sunrise. If you’re trying to catch a glimpse of it, you’ll have to use a telescope.

Despite the “potentially hazardous” label designated by NASA, EarthSky is quick to allay any fears of impending apocalypse (at least from this particular asteroid) because it won’t hit Earth.

Asteroid the size of the Great Pyramid of Giza just flew (safely)

Posted by in categories: asteroid/comet impacts, existential risks

😀


An asteroid about as long as the Great Pyramid of Giza is tall made a “close” approach with Earth on Sunday (July 25), according to NASA calculations.

There is no worry that the space rock poses any threat to Earth, but NASA monitors such rocks to both learn more about the early solar system — asteroids are rocky fragments from that time — and because if their orbits were to change, the asteroid could pose a future risk to Earth.

Nickel isotopes link Siberian Traps aerosol particles to the end-Permian mass extinction

Posted by in categories: existential risks, particle physics

The Sverdrup Basin was a Carboniferous to Paleogene depocenter that accumulated over 12 km of sediment from Carboniferous to Paleogene time18 (Fig. 1). From Late Carboniferous to Early Triassic time, the Sverdrup Basin was along the NW margin of Pangea at palaeolatitudes of 35–40°N (ref. 19) (Fig. 1). Until the EPME, the basin was characterised by a central deep basinal area of fine-grained clastic deposition surrounded by a shallow shelf dominated by biogenic carbonate that transitioned in the late Permian to chert formed by shallow water siliceous sponges19. After the EPME, the Sverdrup basin was dominated by clastic-dominated sedimentation18. In this study, we examined the distal deep-water Buchanan Lake section which preserves outstanding Boreal records of the EPME, followed by the biotic recovery in the Early Triassic5. The Buchanan Lake section consists mostly of black shale of the Late Permian Black Stripe Formation and overlying Early Triassic Blind Fiord Formation that preserves characteristic post-extinction fauna20 (Fig. 2).

During the last decade, the Buchanan Lake section has been extensively examined, and the carbon isotope chemostratigraphy, elemental compositions of the shale, and oceanic palaeo-redox changes have been well constrained5, 11, 19, 20, 21, 22, 23, 24, 25, 26 (Fig. 2). The EPME in the Sverdrup Basin is marked by eradication of silica and carbonate producers along with the onset of a significant negative δ13 Corg shift that has been correlated globally with the dated Global Stratotype Section and Point (GSSP) for the Permian-Triassic boundary at Meishan, China, at ~251.9 Ma (refs. 3, 4, 20, 27, 28) (Fig. 2). The palaeo-redox conditions during the deposition of the Late Permian Black Stripe Formation and Early Triassic Blind Fiord Formation evolved from an oxic water column with a strong redoxcline in the sediments to anoxic and then to sulphidic bottom water conditions (Fig. 2).

I’m 11, I have a physics degree and want to make humans immortal

Posted by in categories: 3D printing, existential risks, finance, food, government, law enforcement, nanotechnology, quantum physics, robotics/AI, transhumanism

As someone with a passionate interest in longevity, transhumanism and biological immortality — I am naturally both excited and optimistic that medical technology will continue to advance in my lifetime — hopefully to the point where humanity has cured or at least greatly mitigated the signs & symptoms of most diseases as well as disabilities, radically expanded human biological lifespan regardless of age, and created a more dignified existence for all as a result of rapid breakthroughs in robotics, AI, automation, nanotechnology, 3D printing and biotechnology — which I hope in turn will largely eradicate poverty, disease, food & shelter insecurity, natural resource scarcity, environmental degradation and income inequality. I know that some of my likeminded friends are far more skeptical that we will ever see outright cures or significant mitigations for major diseases and disabilities — much less radical life extension or perhaps biological immortality in human beings — which are widely available on a commercial basis. They cite their belief that pharmaceutical giants, a plethora of not for profit organizations (i.e., American Cancer Society), and many other allegedly “self-interested parties” supposedly allied with government regulatory bodies — apparently do not want to see diseases or disabilities cured or lifespan significantly extended — EVER — as this would prevent them from earning untold sums selling treatments and supports for such things on a regular ongoing basis (i.e., chemo drugs for cancer, statins for cardiovascular disease, inhaled/oral steroids for lung disease, renal replacement therapy for kidney disease, mobile supports for spinal cord injuries, ect.) They believe that too much money would be at stake, too many jobs on the line and the entire “pharma-medical-academic industrial complex” supposedly at great risk, if actual cures or significant mitigations ever saw the light of day. Some of these friends even cite their belief that fully autonomous, accident proof, self-driving cars will most likely never occur — as it would supposed put the entire auto insurance industry at existential risk as well as deprive law enforcement agencies of a key source of reliable revenue (issuing speeding tickets) This one makes me giggle! 🤭 My friends also believe that radical life extension in human beings — much less biological immortality — would apparently upset the proverbial apple cart — where the “powers that be” are concerned — in terms of everything from the highly lucrative profits which are derived from pharmaceutical sales, old age homes, life and health insurance plans, personal financial services and all of the sales of key products and services associated with the aging process — to macroeconomic considerations such as the long term viability of government entitlement programmes. They believe that government regulatory authorities allegedly working at the behest of the aforementioned self-interested parties will always seek to delay, disrupt or even derail ANY and ALL significant progress into cures/mitigations for disease/disabilities, radical human life extension and/or human biological immortality. Apparently, new biotech start ups which do advance the aforementioned things are allegedly “always aggressively bought out by monopoly capital — with their cures and advances indefinitely suppressed” I personally tend to be more on the positive and optimistic side where these things are concerned — but perhaps these rather pessimistic arguments do have some validity — minus the implied conspiracy theory aspect. Do you think human beings will ever be “allowed” to truly be free from illnesses and disabilities? Will we ever be “permitted” to radically expand our lifespans or even become biologically immortal at some point? Please discuss.


I have already taken a few courses for a master’s in physics at the University of Antwerp and I want to complete it there. In a bachelor’s degree you get a basis of knowledge in physics and quantum physics, but it gets more detailed in a master’s.

The main reason I chose to study physics is because my end goal is to achieve immortality. One of the areas that is important in the study of immortality is physics, but as of yet, there is no mapped out path to achieve it.

Repurposed communications satellites could help save humanity from an asteroid impact

Posted by in categories: asteroid/comet impacts, existential risks, satellites

What do you do if you discover a big rock on a collision course with Earth and have very little time to take action?


Large telecommunication satellites used for TV broadcasting could be quickly and easily repurposed as anti-asteroid weapons according to European aerospace company Airbus.
