Discussion Overview

The discussion revolves around strange hypothetical objects in space, with participants sharing ideas for a science fiction book aimed at children. The scope includes theoretical concepts, speculative objects, and elements from both scientific and science fiction literature.

Discussion Character

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

Main Points Raised

  • Some participants mention Einstein-Rosen bridges as a potential object.
  • Cosmic strings are proposed by multiple participants as interesting entities.
  • A Thorne–Żytkow object is suggested, with one participant expressing a desire for a cooler name.
  • Dyson spheres are noted as a popular topic in science fiction.
  • Various concepts such as dark matter, dark energy, quantum foam, and the multiverse are listed as potential objects.
  • One participant expresses uncertainty about the existence of strange attractors, despite finding them visually appealing.
  • Tachyons and quark stars are discussed, with tachyons being labeled as likely fictional and quark stars as possibly existing.
  • Exotic matter with negative mass and density is introduced as a concept, with a participant speculating on its effects.
  • Anti-matter is confirmed to be included in the story, along with a creature made of it.
  • A Kugelblitz is mentioned as a significant concept in the discussion.
  • One participant shares a riddle about photons, exploring the concept of massless particles and their push.

Areas of Agreement / Disagreement

Participants generally share a variety of speculative ideas, but there is no consensus on the existence or nature of many of the discussed objects. Multiple competing views and uncertainties remain throughout the conversation.

Contextual Notes

Some concepts mentioned, such as strange attractors and exotic matter, depend on specific definitions and may not be universally accepted or understood. The discussion reflects a blend of scientific ideas and creative interpretations, particularly in the context of a children's science fiction narrative.

Who May Find This Useful

Writers and creators interested in science fiction, educators exploring imaginative concepts in science, and enthusiasts of theoretical physics may find the ideas discussed here valuable for inspiration.

Hi

What strange hypothetical objects in space do you know of? Example: Magnetar, pulsar, black hole.

As I am currently writing a sci fi book for children,
I am trying to probe the universe of your mind in search of extraterrestrial objects.

I actually have a wormhole as a character in the book!

Yes, I actually do have cosmic strings!
 
Tannhauser Gate. Sorry.

I don't have that object. But maybe i will have one now!

I only wished the object had a cooler name

Any more suggestions?

Thanks

Why sorry?

If you'd like more science fiction than science, Dyson spheres are a popular topic.

Can you clarify this? It might help with suggestions.

Yes,

There are objects that are considered real like neutron stars and black holes, and objects that stem from Sci-Fi books (the death star or a Dyson sphere). I intended to group these subjects together into one category. So any suggestion, basically, is valid.

Great suggestions! Thank you!

I do have almost all - except branes, extra dimensions, strange attractors, CMB, photon pressure (which I think is a force, not a object). I do have some elements of string theory (multiverse and strings), but I don't know what do to with the extra dimensions - those tiny curled up dimensions, I mean. I need to think deeply about this.
Oh, I had never heard about strange attractors. However, I don't know if they exist in the universe. Do you? I saw a picture of one. It was absolutely beautiful.

If you have more suggestions, more objects, please share them!

Thank you

Well since this is sci-fi there are tachyons. which almost certainly are fiction,
and there are quark stars, which just possibly might exist.

And not to forget chemistry
Heh heh, I liked this one.

Bureaucratium is an element which has a negative half life, becoming more larger, massive and sluggish as time goes by.

When I wrote strange I meant great. As for object vs. force, here's a riddle:

Photons move at c
which means they're massless, see.
Yet they have a push, I hear --
But with no mass, how can they bear?

Exactly, tychions are vital to me at this point

Regarding quark stars, I've read somewhere that they are supposed to have more density than neutron stars. I wonder what the densest form of matter is? Maybe quark-gluon plasma...

I will use the Great Attractor for something mysterious, where something is hidden...

Is this a Freudian slip, a mistake or an homage to pilot Ion Tyche (Stanislaw Lem)?

Or just Tycho Brahe were no post has gone before?

I am writing a science fiction book for children, and not everything has to be based on things that has been done before. If you use your imagination, you could find some new ways of introducing tachyons in a children's book. I can't tell you what I will do with them, unfortunately, because the idea is unique as far as I know.

I think it is found

A Kugelblitz

It's a pity that you haven't asked for the strangest mathematical thing. That would definitely be "The Axiom" as I like to call the axiom of choice.
 
  • #26
Have you included anti-matter?
 
  • #27
Exotic matter having negative mass and negative density,
The more of it there is, the less effect it has on anything else.

No, but I will have fractals :)
Parixit said:

Yes, anti-matter is quite important to my story. I will have a creature made of anti-matter, plus a entire universe.

Well, if, and only if, quark-gluon plasma truly is exotic matter, or have some exotic matter in it, as have been suggested as a type of exotic matter, then yes, I will have exotic matter. Indirectly.
But the true answer is no, I guess, because I will never explain it.

A Kugelblitz still runs the show.
