NEBULA NICKa field guide to why reality doesn't add up

You Shouldn't Exist. Here's Why That's a Problem.

The odds against a universe like this one — let alone you, specifically, reading this sentence — are so small that most physicists just don't talk about it. I made 3 books about the parts they can't explain.

"The universe doesn't owe you an explanation. I found 303 anyway." — Nebula Nick
The Collection

Three books. One impossible universe.

Every video I make ends the same way — with more questions than I started with. So I stopped trying to answer them in 9 minutes and wrote it all down instead. The Hidden Universe Collection is the three books that came out of that: Between the Stars, which covers the mysteries astronomers will quietly admit they can't explain; Time Undone, which walks through the paradoxes that break physics, quantum mechanics, and your own sense of time; and The Dark Void, which is where I stopped reporting the science and started asking what's actually out there. Read them in order and you go from "huh, weird" to "wait, should I be worried about this."

What's Inside

The full contents. Nothing held back.

Three standalone books, sold as one collection — each with its own focus, its own tone, and its own 101 entries.

Book One · 584 Pages

Between the Stars

101 Mysteries Astronomers Still Can't Explain

✓ Documented✓ Sourced
  • The Missing Antimatter — where half the universe went
  • The Hubble Tension — the universe is expanding at two different speeds, and both measurements are right
  • The Great Silence — why a galaxy old enough to be full of neighbors looks completely empty
Book Two · 560 Pages

Time Undone

101 Paradoxes That Have Scientists Questioning Everything

✓ Physics✓ Perception
  • Schrödinger's Cat — the thought experiment that still breaks new physicists
  • The Grandfather's Shadow — what happens if you actually could go back
  • The Paradox of the Book Itself — the one that folds back on you, the reader
Book Three · 537 Pages

The Dark Void

101 Theories About What's Lurking in Deep Space

⚠ Speculative⚠ Theoretical
  • The Fermi Paradox — if the universe is this big, where is everyone
  • The Dark Forest — the theory that says staying quiet is the only thing keeping us alive
  • The Dark Void Beckons — the one I couldn't fully explain, even to myself
Reader Results

What people say after they finish all three.

★★★★★

"I watch the channel every week and still wasn't ready for The Dark Void. Finished it in two nights and now I can't stop thinking about the Fermi chapter."

— Reader, Between the Stars + The Dark Void
★★★★★

"Time Undone is the one I keep recommending. The grandfather paradox chapter alone is worth the whole bundle."

— Reader, Time Undone
★★★★★

"Didn't expect an ebook bundle from a YouTube channel to actually cite real sources. Between the Stars reads like something out of a science journal, not a video script."

— Reader, Between the Stars

About Nebula Nick

Just a guy with too many questions.

I started the channel the way most of these start — a video about the Fermi Paradox at 1am that I thought ten people would watch. It didn't stay ten people, and it turns out the questions don't run out. Every "mystery solved" video just uncovers three more things nobody's solved.

I'm not a physicist. I'm not an astronomer. I'm a guy who reads the papers so you don't have to, boils them down into something you can actually follow in nine minutes, and occasionally stays up too late wondering if any of this is a good idea to know.

The Hidden Universe Collection is everything that didn't fit in the videos — the sourcing, the follow-up questions, the theories too speculative for a script but too interesting to leave out. Read it if you also want to lose some sleep.

Questions

Before you go down the rabbit hole

Is any of this actually real?

Between the Stars covers documented, sourced anomalies in modern astrophysics — real data that doesn't fit our best models, not speculation. Time Undone covers established paradoxes in physics and the psychology of time perception. The Dark Void is different by design — it moves into open theory and speculation about what's out there, and we say so plainly inside. Nothing in any book is presented as more certain than it is.

Your videos are free. Why would I pay for this?

Because the videos are 9 minutes and the books aren't. Every entry gets the full explanation, the sourcing, and the follow-up questions that never make it into a script written for retention. If you've ever paused a video to Google something I mentioned for ten seconds, that's exactly what these books are for.

Why is the whole collection only $27?

Each book is $17 on its own — $51 for all three. Bundled together right now, it's $27. That's a launch price for people finding this from the channel, not a permanent one.

Do I get all three ebooks, or just one?

All three — Between the Stars, Time Undone, and The Dark Void — delivered together as one download the moment you buy. This page only sells the full collection, not individual titles.

What format are the books in, and what do I need to read them?

Digital PDF, all three books in one file set. Read them on your phone, tablet, e-reader, or computer — no special app required, and it's yours forever once you download it.
