A field guide to confirmed strangeness · fact-checked to September 2026

Spooky, but true.

Sixty phenomena from quantum physics, time, the cosmos, life and your own senses — each with the exact number, its error bar, and what it does not mean. Twenty-seven of them you can play with.

01What was measured — exact numbers, with uncertainty 02What it does not mean — the common overclaim 03What is still argued — interpretation, kept apart from data

Every entry is graded

Checked Literature Corrected

Checked against the primary paper or official release; resting on standard literature; or a popular number or framing we had to fix.

The error bar is the spooky part

A 7.6×10⁻²¹ frequency uncertainty. A 4.4σ area increase. Physicists call 3σ “evidence” and 5σ a “discovery” — see every claim on one scale.

Confirmed since 2024

New results that made the cut

How sure are we?

Every significance claim on one scale

Sigma (σ) counts how unlikely a result would be if nothing were there. 3σ is “evidence”, 5σ is a “discovery” — roughly a one-in-3.5-million fluke. Tap any row for the full entry.

Myths to avoid

Real, or too spooky to be true?

Eighteen claims. Some are confirmed physics and biology; some are popular overclaims. Call each one.

Watchlist · as of September 2026

Spooky, but not confirmed

Real data, real excitement — and not enough to call. These stay off the “confirmed” list until the error bars say otherwise.
