Such a space is finite, although without edges or boundary, so that one can indefinitely travel within it. As a result, an observer has the illusion to live in a space 120 times vaster, made of tiled dodecahedra which duplicate like in a mirror hall. As light rays crossing the faces go back from the other side, every cosmic object has multiple images.

The deepscan - picture seems to only be a thumbscan or the size of a nail-head. This perspective is mindblowing.

Well for one thing it means that the actual physical space of the universe is finite. Meaning a definitive number could describe the entire universe.
If the universe were infinite, then no number could describe it's size or in fact it's shape.
How does this model compare to the traditional in terms of size.
Does it have any bearing on the issue of the statistical probability of intelligent life..
The current consensus on the universe is a big bang followed by either a big rip or crunch.
In terms of size it means that although the surface area of space maybe increasing, the actual physical size is finite.
In other words if you were to flatten out space then it would be a great deal larger than it currently is, and the expansion of the universe is the movement towards equilibrium, a state of balance or flatness.
When relating this to the statistical probability of life in a finite Universe, the total number of physical locations life could exist is set to a specific value.
This is important when calculating the statistical probability of life in the universe because if you introduce an infinite to the equation, your answer is always positive.
Side note: - one of the reasons some of my colleagues in the field like to use infinities is it gives them an excuse to stop working and go to the pub
Also in your last post to me, you said you thought intelligent life was common in the universe. What is your reason for thinking so?
Even given that the universe is finite, there are around 400 billion stars in our own galaxy, and we are part of a cluster of galaxies. We know that the universe is not so small as to be smaller than our own cluster or would see the reflection of our own galaxy.
Sol - our sun is just one of those 400 billion stars, It is unthinkable to most scientist that life is unique to this star and this planet.
It's a case of reduction, which is what the Drake Equation is all about.
All the best,
