01 Clarifying the question

On some models, spacetime has no beginning. This is usually either because it extends infinitely into the past or because time deconstructed in some sense. Is one of these models which lack a beginning true?

Current question Is a beginningless model of spacetime true?

Yes

No Reasons challenging the proposition Is a beginningless model of spacetime true?

Physical reality began to exist
Physical reality (all spacetime) began to exist.
This page analyzes six evidences,…

Gravity equations yield a past-bound singularity.

General Relativity's singularity model is true.

Any average-expanding space has a beginning.

Total entropic decay has not arrived yet.

Total generalized entropy is not maxed.

Logically, prior events cannot number to infinity.
This is relevant because if physical reality began to exist, then no beginningless model is true.

Yes Reasons affirming the proposition Is a beginningless model of spacetime true?

Is the Aguirre-Gratton reversed arrow-of-time model true?

The Aguirre-Gratton reversed arrow-of-time model is true. This is relevant because the model lacks a beginning.

Is the Carroll-Chen reversed arrow-of-time to AsDs model true?
The Carroll-Chen reversed arrow-of-time model is true. [See full article.] This is relevant because the model lacks a beginning.
By way of response:
- It implies you're a Matrix brain that just formed.
- It requires a highly improbable bounce stage.
- It destroys probabilistic reasoning
