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!
 
Tannhauser Gate. Sorry.

Do you also have a Thorne–Żytkow object?
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.
 
Dark matter.
Dark energy.
Quantum foam.
Multiverse.
Branes.
Dust.
Vacuum.
Photon pressure.
Colliding galaxies.
Colliding black holes.
Hawking radiation.
Extra dimensions.
Goldilock planets.
Water, lots of.
Frozen oceans.
Superclusters.
The great wall.
Strange attractors.
CMB
Alien life?

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

Have you included anti-matter?
 
Exotic matter having negative mass and negative density,
The more of it there is, the less effect it has on anything else.

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.

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.
