I don't want to spoil it ;D, but It is pretty unlikely that so many planet-orbits are 90° of axis from the accretion disk of the solar-system. I mean, a system could catch an exoplanet, but they can not form by themselves outside of the disk.

TBH, this system is highly likely to exist somewhere.

And remember, we have barely seen much f the universe

Why is it highly likely to exist somewhere?

That's so true, we have not seen much <3

I am certain that a star system like this exists somewhere, but I also know that is what the Valorian star system looks like, and there are 7 other planets further out than Terradyne

Sorry for being so persistent with it, but i am a Physicist ;D
First I wanted to explain it with formulas but I found a pretty good video that explains how a solar-system forms:

I do know how physics work but there has been many discoveries in the past 15-20 years that have boggled scientists due to some observed phenomena that not only defied established science and physics but have thrown known physics out the window.

As one deceased scientist stated (as well as other notables):

(Arthur Eddington? J. B. S. Haldane? Werner Heisenberg? Arthur C. Clarke? Stanley Kubrick? J. B. Priestly)

1. Reality is not only stranger than we suppose, but stranger than we can suppose.
2. Nature is not only odder than we think, but odder than we can think.
3. The universe is not only stranger than we imagine; it is stranger than we can imagine.
4. Not only is the universe stranger than we think, it is stranger than we can think.
5. The universe is not only queerer than we suppose, but queerer than we can suppose.

Statements in this family have been credited to English astrophysicist Arthur Eddington, English biologist J. B. S. Haldane, and German theoretical physicist Werner Heisenberg.
