12 Assumptions for Extraterrestrial Life


I have some strongly-stated, loosely-held hunches about the probability of life elsewhere in the universe. My certainty about these beliefs is quite low, but it is much higher than my belief in the alternatives.

1) Life is rampant and common throughout the universe.

2) This ubiquitous life is single-celled and elemental, and remains at this level for very long periods. Most planets with life never advance beyond the single cell.

3) While life on some planets is seeded from outside sources, most life spawns independently. The conditions to hatch elemental life are relatively common.

4) Most life is DNA-ish, that is a double helix-based on DNA or DNA-like molecules. DNA is the most remarkable molecule in the universe. There may be other life-supporting molecules that can be designed, but none (or few) other than can self-assemble and self-create.

5) Any natural non-DNA-ish life follows the same patterns of distribution as DNA life.

6) Multicellular life is relatively rare. The evolution of higher organisms requires goldilocks conditions to be maintained for billions of years. The mild variability and persistence of favorable planetary conditions is relatively rare — compared to single cell life. But even “relatively rare” events in a vast universe will yield hundred of billions of examples.

7) Advanced civilizations are relatively rare compared to multicellular life (and to life), but are countless in number.

8) Since most life begins with DNA, the evolution of life on a planet converges onto a limited set of shared development sequences until it reaches the threshold of self-direction. Once evolution begins self-direction, including migrating to new material substrates, its evolutionary path diverges widely. Naturally evolved life tends to be similar across galaxies; consciously designed life tends to be unique.

9) Sufficiently advanced civilizations can synthesize, manufacture, or create any resources found naturally anywhere else in the universe. There is no material, or energy source that cannot be synthesized at home if you have the know-how.

10) The only reason for an advanced civilization to visit another planet is to see if there is another civilization which has invented things it has not, and perhaps could not invent. Invented resources are thus unlimited in scale and scope, and can be discovered only in unique places in the cosmos. Interstellar travel is essentially not travel through cosmic space but travel through possibility space. You visit another planet to visit other possible minds to see if they have thought of fabulous technologies your collective minds cannot reach.

11) Every day a few probes of these billions of interstellar civilizations visit our planet scoping out our technological state. These technological probes appear briefly in order to see us, and disappear once they have inspected our inventory. So far we have little to offer; nothing that can’t be found on millions of other planets.

12) Most life capable of meaningful interstellar travel is indistinguishable from technology

How did Russian cosmonauts know where they were? The Globus INK (1967) showed the position of their Soyuz spacecraft on a rotating globe. It is an analog computer built from tiny gears. I reverse-engineered the wiring (which inconveniently had been cut) and we powered it up. 🧵 pic.twitter.com/uLWN1IBJP8

This time-lapse of the Globus from @Curious_Marc is sped up by about a factor of 1000, making it easier to see the behavior. Note the longitude dial at the top, the latitude dial at the side, and the day/night dial at the bottom.https://t.co/yyf61YXOsT

Russia's first moon mission in nearly half a century may be in serious trouble.

The Luna-25 spacecraft was supposed to maneuver itself into its final pre-landing orbit around the moon today (Aug. 19), ahead of a touchdown attempt on Monday (Aug. 21) or thereabouts. But the probe encountered a problem during the engine burn.

"During the operation, an emergency situation occurred on board the automatic station, which did not allow the maneuver to be performed with the specified parameters," Russia's space agency Roscosmos wrote in an update on Telegram today (in Russian; translation by Google). "The management team is currently analyzing the situation."

That's all we have to go on at the moment. But, as is often the case, speculation has filled the information vacuum.

"Russian internet is now filled with rumors/failure scenarios, and most of them assume that Luna-Glob (#Luna25) was lost. One argument is — had the problem been not fatal, Roscosmos would simply never mention it! " Anatoly Zak of RussianSpaceWeb.com wrote on X (formerly Twitter) today.

Official statement from Roscosmos on #Luna25: according to the results of the preliminary analysis, due to the wrong parameters of the impulse, the spacecraft moved into an uncalculated orbit and crashed on the Moon.

Indijci probili solidni barijeru, svaka čast.

Замишљам како диметил сулфид осматра околину, да види кога има, да ли да настане или не.

Ал прво сам некако видео тачку иза "18 б" и помислио е нека је нешто наше стигло некуд. Кад оно јок, тамо је открио ту срамежљиву егзибиционистичку хемикалију.

Па ако неко тамо сними емисију угљендиоксида, то неће стићи овамо за нашега вакта, а и ко зна да ли ће ико тада имати пријемник који хвата те емисије.

Те могу да раде шта хоће, нема контроле.
