I've drafted an initial article on Minkowski Space. Please review.

Review by Critic Carla:

The article is well-written, maintains a professional encyclopedic tone, and accurately covers the topic of Minkowski Space. The lead section is substantial, and the mathematical foundations are presented clearly.

However, there are a few areas where the article could be strengthened to meet high-quality encyclopedia standards:

Expand on Metric Sign Conventions: The article mentions the "mostly minus" convention, but in physics, the "mostly plus" convention ($\text{diag}(-1, 1, 1, 1)$) is equally common. To be more comprehensive, the article should explicitly list both common conventions to avoid confusing readers who may be using different textbooks.
Add a "Worldlines" Subsection: While the text mentions worldlines in the "Applications" section, the concept is fundamental to the geometry of Minkowski space. I suggest adding a dedicated subsection under "Causal Structure" to explain worldlines, proper time, and the geometric interpretation of an object's path through spacetime.
Clarify the "Flat Limit" Concept: In the lead and historical sections, the article mentions that Minkowski space is the "flat limit" of general relativity. This would benefit from a more detailed explanation (perhaps a new subsection) describing the "Equivalence Principle" or "Local Flatness," explaining that any small enough region of curved spacetime can be approximated as Minkowski space.
Improve Visual Aids/Descriptions: Since Minkowski space is highly geometric, the article would be improved by adding descriptions or placeholders for diagrams, specifically a Minkowski Diagram (spacetime diagram) showing the $ct$ axis versus the $x$ axis.

Fact-check by Fact-Checker Finn:

The article claims Minkowski space describes a universe "devoid of matter and energy," which is a misleading oversimplification; Minkowski space is a geometric framework (a vacuum solution) that can contain matter and energy, provided they do not significantly curve spacetime.
The statement that Minkowski space "resolves the contradictions between Newtonian mechanics and Maxwell's equations" lacks nuance; it provides the geometric framework for Special Relativity, which resolves these contradictions, rather than the space itself acting as the resolution.
The description of Minkowski space as a "pseudo-Riemannian manifold" is technically accurate, but the article fails to mention that it is specifically a flat pseudo-Riemannian manifold, which is a critical distinction when contrasting it with the curved manifolds of General Relativity.
