The Xeelee Sequence is a series of hard science fiction novels, novellas, and short stories written by British science fiction author Stephen Baxter (same author of Manifold).
This blog will cover its cosmology and stuff.
The universe is finite, closed, folded over on itself:
The universe not only has the standard 3 dimensions of space + 1 of time, but it also has 7 extra compactified dimensions, making it overall 11-dimensional. These extra dimensions is what they call "hyperspace":
The universe is composed of quantum wave functions, sheets of probability that links matter and time:
The quantum wave functions are the fundamental building blocks …
Pigeon Toilet
In the heart of a bustling city, where towering skyscrapers cast long shadows over cracked sidewalks, there lived a pigeon. Unlike his fellow pigeons, who scavenged for breadcrumbs and dodged car tires, this pigeon had higher ambitions. He was a bird of class, dignity, and, most importantly, hygiene.
One fateful evening, during a torrential downpour, the pigeon took shelter through an open window of a rundown apartment. Inside, he found a strange porcelain throne filled with water. It was unlike any birdbath he had ever seen. He hopped onto the rim, took a cautious sip, and marveled at its pristine, ever-replenishing nature.
From that moment on, the pigeon abandoned the grimy streets and made the toilet his personal sanctuary. But he didn’t …

There are multiple Histories (timelines). They are analogously stated to be parallel corridors, existing independently of each other. In some of those, the laws of physics are different:
There is an infinite number of possible timelines:
Everett's Many Worlds Interpretation is the framework used to explain how the multiverse works. For every moment, an infinite number of worlds is generated:
Every interaction, unconsciously or consciously, causes endless Histories to branch off:
All possible Histories exist in the Multiplicity. Its an endless catalogue of "What-Can-Be". Every History which was po…
Ruckerverse Cosmology
This is a blog dedicated to the cosmology of the Ruckerverse, the shared science fiction multiverse of American mathematician Rudy Rucker.
Many universes exist:
There are at least trillions of these universes/timelines:
There exists a fifth dimension:
There is not only that, but an endless series of higher dimensions:
There is an infinite-dimensional Hilbert space:
There are also higher time axes/temporal dimensions. They are referred to as "Paratime", where aliens reside:
Paratime is stated to be infinite-dimensional (which makes sense, considering the aforementioned context):
Aliens have control over Paratime:
There are levels of infinity, such as aleph-null, aleph-one, and so on:
These infinities are very much real:
Georg Cantor exists in the vers…

Turns out an otome game isekai might be Tier 1...
There is an infinite number of parallel worlds:
Turns out it's actually "countless" instead of "infinite", as the raws use 無数 (Musu) instead of 無限 (Mugen)
The structure that holds those worlds is equated to a Tree, where each of its countless branches are a world of its own:
A single world/branch of a tree is implied to be a universe:
The caretakers of the Tree are gods that hold influence over all of the Tree's worlds:
It's implied there are numerous trees, comprising a "forest". The other trees are called Otherworlds, and they each have their own god that influences its worlds/branches:
Kugelschreiber (a caretaker of a Tree) states that there might be a…
