Discussion Overview

The discussion revolves around hypothetical scenarios for removing all oxygen from Earth's atmosphere, primarily for a science thriller novel. Participants explore various imaginative and scientifically-rooted ideas, considering both natural and man-triggered events.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested
  • Creative brainstorming

Main Points Raised

  • One participant suggests burning all fossil fuels to reverse the oxygen production process, though this would take a long time.
  • Another participant proposes a science fiction scenario involving nitrogen-breathing aliens using an antimatter bomb to remove oxygen quickly.
  • Jeremy Robinson mentions the possibility of a natural phenomenon, such as lightning or a comet-induced storm, to rapidly deplete oxygen.
  • There is speculation about the effects of such an event on stored oxygen in tanks and the survival of plant life, with some participants suggesting that certain forms of life might survive to eventually replenish oxygen.
  • One participant raises the idea of a nuclear winter scenario leading to a lack of photosynthesis and oxygen production.
  • Another participant discusses the potential for engineered bacteria to create a greenhouse effect, inadvertently leading to oxygen depletion.
  • Concerns are raised about the feasibility of certain scenarios, such as the survival of plant life without oxygen and the mechanics of how oxygen could be removed without affecting all forms of life.

Areas of Agreement / Disagreement

Participants express a range of ideas and hypotheses, with no consensus on a single method for removing oxygen or the implications of such an event. The discussion remains unresolved with multiple competing views and speculative scenarios.

Contextual Notes

Limitations include assumptions about the survival of various life forms, the mechanics of oxygen removal, and the timeline for such events. The discussion does not resolve these uncertainties.

Who May Find This Useful

Writers, particularly in the science fiction and thriller genres, as well as those interested in speculative scenarios related to atmospheric science and environmental impacts.

It might be easier to remove the oxygen over a longer period of time. The main characters could also be an astronauts instead of a diver. Mysteriously, mission control, stops responding, and astronauts lose all contact with earth. They are meanwhile quite a ways away from earth, and don't get back for some time, could be a week, a month, or a year. Somehow only one survives. Maybe a few could die in space trying to repair something, only one survives in the end, and ends up in the ocean climbing out of the capsule with a space suite on looking at a red sky.

Participants of this thread may like to know that the novel was published a couple of weeks ago, and has been reviewed by Publishers Weekly. Snippet below:

For help developing the crazy, but plausible, science at the core of the SecondWorld story, I must thank “Chemisttree” from physicsforums.com, where I received ideas and advice from a number of scientists in a variety of fields.

Good luck OP with your book!

And YAY chemistree!

Oh WOW!

Thanks Jeremy.

we know by ultra violet radiation the oxygen will converted to ozone. so if huge quantity of ultraviolet radiation are applied it may definitely convert every oxygen molecule to ozone at least temporally

And fry everything on the planet at the same time most likely! One hell of a situation to get out of!

Hey all,

I'm a science thriller author (www.jeremyrobinsononline.com) and I've got a new story idea with a really big problem. Basically, I need to remove all of the oxygen from Earth's atmosphere, preferably fast, but I can adapt to a longer time frame if need be. Now, this is for a novel so it only needs to be rooted by facts...so imaginations are welcome.

ALSO possible for the story would be poisoning the atmosphere...keeping the O2, but making it toxic. But removing the O2 is somehow cooler, I think.

I have some ideas, but nothing great. Any thoughts? Oh, and this would have to be either natural (cosmic counts) or natural but triggered by man. No doomsday devices like the O2 Destroyer in Godzilla. :)

Thanks for your help!

Huge electrical discharge converts it all to ozone? ?
