"Titan: Possibility of Life" and it may be vaguely like earthly jellyfish



Titan: Possibility of Life” is an engaging 2017 documentary (43 minutes) by Aerospace Engineering.


The film shows the internal structure of Titan which, like Europa, has am underwater ocean. But the now famous thick atmosphere, with a surface of lakes and mountains that can erupt with ammonia water, is explained by violence in the Solar System about 4 billion years as outer planet orbits expanded, throwing a lot of objects into the atmosphere of Titan (as well as Earth).

The chemistry of the atmosphere is explained, as an organic chemistry lesson.  A post-doc fellow proposes how protein chains could develop and organize themselves into a helix similar to DNA.  
  
Then a proposal for metabolism is suggested, where energy is released by hydrogen reacting with acetylene. Indeed, there are studies suggest this chemistry might enclose a cellular structure.  One scientist suggests that life forms on Titan might be like large sheets of paper with little suckers to get food from the environment, maybe analogous a little bit to jellyfish on Earth (not exactly “Free Fish).

The film presents a lake of host asphalt in Trinidad that may

"Unbelievably Strange Planets in Space" include Titan


Unbelievably Strange Planets in Space” by Ridddle, starts out by exploring some very hot planets, including a couple where it rains glass, and where winds are many multiples of the speed of sound. 


It explores some hot Jupiters, and planets with multiple suns, and a planet around a blue giant, before it suddenly switches gears and looks at the practice of “BARE” air surfing, and then imagines moving to Titan.

In a reducing atmosphere, acetylene would be the fuel of choice, and cities or space stations might float in the thick atmosphere because of low gravity (1/7 of Earth).  But it also proposes a rail transit system.

Actually, it might be possible to building floating cities around Venus, because 30 miles altitude the temperatures are Earth-like.  Get over surface-ism.

"Mysterious Activity on Saturn's Moon Titan": group claims military-style building spotted on surface


SecureTeam10 presents "Mysterious Activity on Saturn’s Moon Titan" (10 min)


The film shows a small isthmus in Titan’s second largest methane lake, which disappears and reappears.

Later (at 7:36) the film shows what looks like man-made military buildings, square shaped, on one of the plains near a lake, claiming aliens built them, and then it shows images of cylindrical UFO’s called “RingMakers” around Saturn.

Astronomers have found vinyl cyanide on Titan, which is capable of making cell membranes, as explained here in Popular Mechanics.

Russians claim to have made an artificial cell which can self-replicate with this kind of membrane and various other methyl compounds (like crystal meth) without water.

The video mentions the film “Oblivion” (4/23/2013) as where Earthlings fled to.

"Is VidAngel Legal?" I think this does belong in DC Shorts


"Is VidAngel Legal?" is indeed an interesting meta-short film "about" legal skullduggery in Hollywood.

Here is the company's own version of the legal fight with Hollywood.

The narrative involves a "secret" contract in Hollywood to block all user filtering, which was apparently discovered by North Korea's Sony Pictures hack;  there followed Congress's "Family Movie Act" which tried to make the service (for parents to filter objectionable content from movies) legal.

See also my "filering Internet content" blog for coordinated post (see Blogger profile). It's conceivable that VidAngel's legal issues could become relevant in the fight against Section 230 motivated by the Backpage controversy.

"Where Your Cat Goes May Blow Your Mind" from NatGeo, from North Carolina


Where Your Cat Goes May Blow Your Mind”, from National Geographic, is a short film documenting a cat-tracking project in North Carolina among cat owners who allow cats to roam.


The idea is to assess the effect of the cats on wildlife.

When owners went away for one weekend, the cat navigated toward a house he used to live in a mile away, and returned when the owners returned.

"Jack Andraka: The Hidden Innovator" talks about bullying and then science and nanobots


Jack Andraka gives a talk in September 2015, “Jack Andraka: The Hidden Innovator” for Wired for Wonder.


In the early part of the video he addresses anti-nerd and ant-gay bullying (the latter may follow the former) in middle school. 

He presents many illustrations from his progress toward his pancreatic cancer test, which won a big science fair award in Pittsburgh in 2013 when he was 16. 

Toward the end he presents ideas, which he works on at Stanford where he now enters his junior year, toward using naontechnology to deliver anti-cancer drugs or to even detect early cancers.  One can imagine, from the illustrations, his getting together with Reid Ewing and making an animated film using manga or Danganronpa characters interacting with nanobots inside the human body

"Could the God Particle Wipe Out the Universe?" That is, the Higgs Boson


Jack Daniel asks “Could the God Particle Wipe Out the Universe?” in another Strange Mysteries video.


The video concerns the Higgs, Boson, an elementary particle which is theoretically capable of causing “vacuum decay” which spreads through the Universe at the speed of light. It would cause existence to fail. But since space expands faster than the speed of light, it might never reach us even if it formed.
The videos is in SM’s usual 4-part format.  (See earlier film March 21, 2014 about Higgs.)
