Cosmic Queries – ALIENS! with Jake Roper

October 24, 2025

Key Takeaways Copied to clipboard!

  • The consensus for the easiest alien movie to survive is *E.T.*, though the risk of cross-species contamination from E.T.'s unknown biology is a significant caveat. 
  • The possibility of weaponizing light into a super laser capable of instantly turning a person to ash, as seen in *War of the Worlds*, is theoretically possible if enough energy can be focused to vaporize all bodily moisture, though the instantaneous nature depicted is questionable. 
  • The most believable fictional aliens are those that move beyond humanoid forms and challenge human comprehension, such as the shapeshifting parasite in *The Thing* or the non-material entities in *Contact*. 
  • The conversation briefly shifts to an in-depth discussion about the film *The Matrix*, with participants debating the number of sequels and their familiarity with the franchise. 
  • A philosophical question is posed during the closing moments: "are you a virus on this earth?" 
  • The segment concludes with host Neil deGrasse Tyson bidding listeners to "keep looking up," followed by an advertisement for Odoo business software. 

Segments

Easiest Alien Movie Survival
Copied to clipboard!
(00:05:13)
  • Key Takeaway: The movie E.T. is considered the easiest alien film to survive, provided the risk of contracting unknown bacteria or viruses from the alien is ignored.
  • Summary: The alien in E.T. was conceived by Steven Spielberg as a plant-based life form, not an animal, which explains its interaction with plants. The primary survival risk stems from potential cross-species contamination, as the alien’s biology is unknown to Earth life. Diseases specific to one life form are often not contagious to others, even those sharing DNA, suggesting the contamination risk might be low but remains a major unknown.
War of the Worlds Laser Weaponry

(00:09:16)
  • Key Takeaway: The War of the Worlds alien weapon, which turns people to ash, requires enough energy to instantly vaporize all bodily moisture before consuming the remaining material, a process likely taking longer than depicted.
  • Summary: Harnessing light as a weapon is fundamentally about transferring energy from one point to another, similar to conventional weaponry. To reduce a body to ash instantaneously, the energy beam must boil and evaporate all internal liquid content first. The weapon’s apparent selectivity, only affecting humans and not surrounding structures, suggests it might be tuned specifically to human chemistry, possibly utilizing microwave-like energy that targets water molecules.
Government Secrecy and MIB

(00:16:05)
  • Key Takeaway: If aliens were discovered, the government would likely establish a secret organization similar to Men in Black to shield the public, especially if the aliens were sentient and disruptive to current understanding.
  • Summary: The government would likely hide knowledge of sentient, humanoid aliens because such information is profoundly disruptive to public understanding. While an organization like MIB would probably exist, it would lack the cool, action-oriented elements seen in the films. The search for extraterrestrial life (like missions to Mars or Europa) focuses on microorganisms, which is less disruptive than confirming the existence of intelligent, mobile beings.
Favorite Fictional Aliens

(00:23:21)
  • Key Takeaway: The most imaginative fictional aliens are those that defy humanoid structure, such as the parasitic, multi-mouthed Xenomorph from Alien or the amorphous, non-biological Blob.
  • Summary: Chuck’s favorite alien is the Xenomorph from Alien due to its cunning intelligence, unknown motivation, parasitic lifecycle, and complex anatomy (mouth within a mouth). Jake favors the alien from The Thing because its parasitic nature creates a compelling conundrum: the host remains unaware it is being controlled by an alien entity. Neil champions The Blob for its lack of traditional humanoid features, noting it was initially transparent before consuming its first victim.
Arrival Communication and Logic

(00:32:51)
  • Key Takeaway: The communication method in Arrival, where the heptapods write backwards through a transparent medium, raises logical questions about whether they were intentionally accommodating human perspective rather than writing in their own orientation.
  • Summary: The choice to send a physicist and a linguist in Arrival was specific to deciphering communication, but an astrobiologist and a cryptographer might be more appropriate initial choices. Neil pointed out that if the aliens understood human coordinate systems (latitude/longitude based on Greenwich), they would likely have learned English quickly rather than relying on complex visual translation. The aliens’ apparent consideration in writing backwards suggests a level of cultural understanding that contradicts the initial communication barrier.
Alien Attack Response

(00:38:06)
  • Key Takeaway: If aliens attacked with a mothership from orbit, the most rational first response is to wait and observe rather than engaging in futile, immediate aggression against superior technology.
  • Summary: Jake’s first action upon an alien attack would be to relax, perhaps enjoy a glass of wine, and wait for the outcome, assuming ground troops are not immediately involved. Neil suggests that engaging a superior force, like shooting at a mothership, is ineffective movie trope behavior. Neil implies he would use his government connections to secure a bunker while Jake waits for the conflict to resolve itself.
Believable Alien Depictions

(00:44:48)
  • Key Takeaway: The most believable depictions of aliens in modern sci-fi, like Arrival, are those that prioritize non-violent, authentic societal reactions over immediate aggression.
  • Summary: The film Arrival is praised for its scientific realism in attempting to decipher alien language and for portraying authentic human reactions to non-violent first contact. The film Contact is also cited for authentically depicting societal reaction to the knowledge that intelligent life exists. The concept of non-biological, machine-based life forms, like the Stargate Replicators, is considered a highly probable form of alien encounter due to self-duplication and the implications of the technological singularity.
Matrix Film Analysis

(00:54:58)
  • Key Takeaway: Participants express varying levels of familiarity and commitment to analyzing The Matrix film series, with one host claiming they can overanalyze the first movie.
  • Summary: The discussion briefly focused on the film The Matrix, leading to a minor disagreement over whether there is only one film or multiple sequels. One participant admitted to having seen the original film an excessive number of times. The segment ended with a reflection on the depth of analysis possible for the first movie.
Closing Philosophical Question

(00:55:28)
  • Key Takeaway: A profound, existential question regarding humanity’s role on Earth—whether humans function as a ‘virus’—was posed near the conclusion of the main content.
  • Summary: Following the film discussion, a direct question was raised concerning humanity’s impact on the planet, framing humans as a potential biological virus. This moment served as a brief philosophical interlude before the final sign-offs.
