The Ursa Mirage Giveaway — Thank you!

Hi!

I just wanted to take a moment to say a genuine thank you to everyone who entered the giveaway for The Ursa Mirage.

Seeing over 1,000 of you enter and nearly as many add the book to your shelves, was completely overwhelming in the best way possible. When you put a story out into the world, especially a dense, high-concept sci-fi book you’ve poured months of work into, you always wonder if it will find its audience. Seeing this kind of response means more than I can say. The book is in its lowest price possible on Amazon in case you are interested.

To the 100 winners: your copies should already be sitting in your Kindle libraries! I hope you enjoy the trip into the story, and if you have a spare minute when you finish, dropping an honest rating or review on Goodreads would mean the world to me.

To everyone who didn’t win, thank you for stopping by and checking out the book. If you decide to pick up a copy on Amazon down the road, I hope it keeps you hooked.

Thank you all for making this release so special.

Cosmic Scale: Why Space-Time Is the Ultimate Mystery

D.T. Rivellore — Wed, 15 Jul 2026 00:00:00 GMT

One of the most mind-bending aspects of theoretical cosmology is how light, distance, and gravity interact over immense scales. From gravitational lensing to atmospheric refraction, the universe is full of phenomena that challenge what we think we are seeing.

The title The Ursa Mirage hints at that exact tension — the line between physical reality, theoretical observation, and the vast scale of the cosmos.

Writing hard science fiction means respecting the intelligence of the reader. It means ensuring that when complex theoretical concepts appear, they are treated with mathematical and logical discipline rather than fantasy hand-waving.

To everyone currently reading or keeping it on their shelves: thank you for being an audience that appreciates high-concept, intellectually demanding sci-fi.

Spooky Action at a Distance: The Strange World of Quantum Entanglement

D.T. Rivellore — Wed, 18 Mar 2026 00:00:00 GMT

In 1935, Albert Einstein, Boris Podolsky, and Nathan Rosen published a paper highlighting a phenomenon that Einstein famously dismissed as “spooky action at a distance.” Today, we know it as quantum entanglement.

At its core, entanglement describes a state where two particles become inextricably linked. Measure a property of one particle — like its spin or polarization — and you instantly know the corresponding property of its pair, regardless of whether they are separated by a few millimeters or a billion light-years.

What makes this so mind-bending to natural philosophy is what it implies about locality and observation:

The Interconnectedness: Entangled states suggest that physical information isn’t strictly confined to isolated local regions in space-time.
The Measurement Problem: The universe seems to refrain from defining certain properties of a system until an observation actively forces a collapse into a definitive state.

It is precisely these theoretical edge-cases — where the fundamental laws of reality challenge human intuition — that make quantum mechanics such a rich playground for speculative thought. When science reaches the boundaries of what can be directly observed, it naturally sparks the imagination.

The Ursa Mirage is where I took that imagination for a walk: a hidden city on a New Mexico mesa, an impossible correlation between distant particles, and the ten years it takes for the equations to sing. You can read it on Amazon, or add it to your shelf on Goodreads.
