This one has an unusually clean disproof. We searched twelve of Carroll’s English works — 2.1 million characters — and the word “forever” does not appear once. Not in this exchange, not anywhere: Carroll’s Victorian English writes it as two words, and “for ever” turns up just thirteen times in the whole corpus, never in anything like this. The line is usually credited to a modern film of Alice, often with the White Rabbit answering; we could not test that, because every film-transcript site we tried is blocked from this machine. So we report it as the common claim and leave the author unestablished.
“How long is forever? Sometimes, just one second” Author unknown — not Lewis Carroll. The word "forever" appears nowhere in his twelve English works. Source: Quotle.info

“How long is forever? Sometimes, just one second.”
Usually circulated as a two-hander, with Alice asking and the White Rabbit answering. Neither half occurs in Carroll. The nearest real thing in Wonderland is the Hatter’s quarrel with Time. He tells Alice they fell out “last March… at the great concert given by the Queen of Hearts”, where he sang “Twinkle, twinkle, little bat” and the Queen “jumped up and bawled out, ‘He’s murdering the time! Off with his head!’” Ever since, the Hatter says, Time “won’t do a thing I ask! It’s always six o’clock now.” That is a joke about time being a person you can offend, not a sentiment about how long a moment can feel.
We downloaded the Project Gutenberg texts of twelve of Carroll’s English works — Alice’s Adventures in Wonderland, Through the Looking-Glass, Alice’s Adventures Under Ground, The Nursery “Alice”, The Hunting of the Snark, Phantasmagoria and Other Poems, Songs from Alice, Sylvie and Bruno, Sylvie and Bruno Concluded, A Tangled Tale, The Game of Logic and Symbolic Logic — flattened every line break so no phrase could hide across a line ending, and searched 2.1 million characters of it. The word “forever” occurs zero times. Neither “How long is forever” nor “just one second” occurs at all.
Victorian spelling is part of why this is so decisive. Carroll writes the idea as two words, and “for ever” appears only thirteen times across all twelve books — in Through the Looking-Glass, The Hunting of the Snark, Sylvie and Bruno and its sequel, A Tangled Tale, Phantasmagoria and Symbolic Logic. A modern one-word “forever” in a sentence credited to him is, on its own, a reasonable thing to be suspicious of.
We also ran the phrase through a full-text search of the whole of Wikiquote — an insource: query, which reads the raw wikitext of every page on the site — rather than only Carroll’s own page. “How long is forever” returns exactly one page across the entire site, and it is the episode list for season two of the animated series Teen Titans (2004), where it is an episode title — unrelated, and mentioned here only to be precise about what the search returned. The phrase is on no Carroll page, no Alice page, and no Alice-film page.
Wikiquote’s Misattributed list for Wonderland ↗ does not include this line — it currently carries two other modern lines — and neither does Carroll’s own page ↗. That is an absence of a debunk, not a debunk: it means nobody has filed this one yet, not that it checks out.
No rights badge. Carroll’s books are long out of copyright, but this exchange is not from them, and we could not establish where it is from — so there is no work whose status we can honestly report. If it does come from a modern film, as is commonly said, it would be in copyright to that film’s studio.

Two things get credited wrongly here at once: the author, and the speaker. Neither survives contact with the text.

Most commonLewis Carroll, in Alice’s Adventures in Wonderland Refuted
The word “forever” does not occur in Wonderland ↗, in Through the Looking-Glass ↗, or in any of the ten other Carroll books we searched. The exchange cannot be his.
✕
The speakerThe White Rabbit Refuted
The version in circulation usually assigns the answer to the White Rabbit. He says nothing of the kind. He does not appear in Through the Looking-Glass at all, and in Wonderland his lines run to “Oh dear! Oh dear! I shall be late!” and “The Duchess! The Duchess! Oh my dear paws!… She’ll get me executed, as sure as ferrets are ferrets!” The full text ↗ is there to check.

Commonly reported originA modern film of Alice Documented — unverified here
Widely stated online, and plausible on the face of it, but every film-transcript host we tried is blocked by this machine’s network policy, so we could not read a script to confirm it. We are not going to credit a studio on the strength of other people’s summaries.
✓What we can state flatly: the full text of Wonderland ↗ does not contain the word “forever”, and neither does any other book Carroll published. Where the exchange did come from, we have not established.
Context
Why it mattered
The appeal is obvious — it is a neat, wistful paradox about how a moment can outlast a decade — and so is the reason it gets pinned on Wonderland: the book is genuinely obsessed with time misbehaving. That resemblance is close enough to be convincing and wrong, which is the most useful kind of misattribution to take apart.
Carroll’s own time jokes run the other way. In Wonderland, Time is a person the Hatter has offended, so the clock is stuck at six and it is always tea-time — a bureaucratic grudge, not a romantic paradox. The invented line has the melancholy of a film; the book has the pedantry of a mathematician.

1832–1898 · English author, mathematician & logician
Charles Lutwidge Dodgson — Lewis Carroll on the title page — taught mathematics at Christ Church, Oxford for most of his adult life, and wrote the two Alice books and a shelf of logic puzzles alongside it. His actual sentences are odd in a specific way: precise, deadpan, and usually about the rules of language rather than about feelings. That is worth knowing, because the lines invented for him are almost always the opposite — warm, motivational, and about you.
