Spacetime Metric Engineering

A 13-lecture series on warp metrics, the quantum vacuum, and what experimenters can actually try.

The four-tier disciplinary spine

Every claim across the thirteen lectures is placed on one of four tiers. The spine is a tool — once you have it, you can read any new physics claim and place it correctly. The series exists to give listeners that tool.

1

Peer-reviewed, replicated

Published in a peer-reviewed journal and independently replicated by another lab. The strongest claim a physics result can carry. Examples: the Casimir effect (Casimir 1948, replicated Sparnaay 1958 and Lamoreaux 1997); Lattice Confinement Fusion (Steinetz et al. 2020 with Astral Systems + Clean Planet replication); the dynamical Casimir effect (Wilson 2011 confirmed by Lähteenmäki 2013 PNAS and Schneider 2020 PRL).

2

Peer-reviewed, once

Published in a peer-reviewed journal but not yet independently replicated. Real science waiting for confirmation. Examples: the Alcubierre warp metric (CQG 1994 — mathematically valid, no physical demonstration); the White et al. 2021 EPJ-C worldline-numerics paper (mathematical correspondence claim, not a physical warp bubble).

3

Patent-attested

A patent has been filed and the filing institution has attested the device is operable. A legal-engineering claim, not a peer-reviewed scientific result. Example: the Pais patent series (NAVAIR, Sheehy attestation). To date no independent peer-reviewed replication has been published.

4

Claim-only

Asserted publicly without peer review, without patent, and without independent replication. The lowest evidential tier. Cited only where the claim itself is notable enough to discuss; never confused with the higher tiers.

The discipline isn't to dismiss anything; it's to know what you're looking at. A peer-reviewed-once result is a finding that hasn't been independently confirmed yet — that's a state of partial knowledge, not failure. A patent-attested device is a legal-engineering claim, which is a different kind of thing than a peer-reviewed scientific result. Neither is the other.
