Brand system · v1.0
A publisher's visual identity
should earn its own restraint.
Antigravity is an open-science publisher — preprints, data, and code, across the sciences, with an in-house lab of our own. This brand system is built on two ideas. First, that the work we publish is already dense enough; the page should stay quiet. Second, that a publisher outlives any trend, so the type should be serifed and the marks should be geometric. What follows is the system we use.
01The mark
Warp — Alcubierre f(r)
The single stroke is the shape of the warp factor in Miguel Alcubierre's 1994 metric — the only rigorous solution in general relativity for what 'antigravity' would mean. It reads as a function plot to physicists and as an elegant silhouette to everyone else.
Horizontal · LogoWarp — for headers, banners, lockups with wide space
Square · LogoWarpMark — for favicons, avatars, OG images, app icons

Antigravity, set in Fraunces
One word, no internal capital. Set in Fraunces optical-500 with tight (−0.02em) letterspacing. The company is Antigravity S.L., a Spanish limited liability company based in Valencia.

Three typefaces, three jobs
Fraunces carries display and serif body. Inter carries UI and paragraph body. IBM Plex Mono carries metadata — timestamps, identifiers, captions, equations in prose. Nothing else.

04Color
Paper, ink, one accent
The system is a paper-and-ink duotone with a single warm accent. No gradients. No shadows beyond a hairline. The accent is used only for one-off emphasis: arXiv links, hover states on links, and the single active indicator in navigation.

05Spacing & layout
Three measures, one grid
Measure classes cap line length for readability. All pages align to max-w-[var(--measure-frame)] with 6/10 px side padding. Sections are separated by 20-28 rem vertical rhythm and a 1px top rule.
.measure-narrow
36rem / ~65ch
Long-form prose, block quotes, CTA copy
.measure-wide
56rem / ~90ch
Figures, images, wide lockups
.measure-frame
72rem / page max
Section wrappers and header rows
06Voice
Plain sentences about hard things
We write like researchers, not marketers. Short sentences. Concrete claims. No hype, no exclamation marks, no 'revolutionizing the future of…'. If we cannot ship or simulate a claim, we do not make it.
✗ Don't
- “Revolutionizing the future of propulsion.”
- “We don't study the future — we build it.”
- “Pioneers in frontier science.”
- “Unlocking the next chapter of humanity.”
07Usage
How not to break the mark
The mark is a single stroke and a single baseline. If you are tempted to fill it, duplicate it, skew it, rainbow it, or embed it in a seal — resist. Use the variants provided. The identity relies on geometric restraint.
✓ OK
Ink on paper, single color, correct aspect.
✓ OK
Paper on ink, inverted, same stroke weight.
✗ Don't
Stretch or skew the mark.
✗ Don't
Recolor outside the palette.
✗ Don't
Add shadows, glows, or gradients.
✗ Don't
Place on busy / patterned backgrounds.

All marks are React components living in src/components/icons/logo/warp.tsx. Import them where you need them. For static SVG exports, copy the source paths from the components directly.
import {
LogoWarp, // horizontal, 5:1
LogoWarpMark, // square, with baseline — for favicon / OG
LogoWarpLockup, // mark + wordmark, inline
} from "@/components/icons/logo/warp";
<LogoWarp size={96} className="text-[var(--color-ink)]" />
<LogoWarpMark size={32} />
<LogoWarpLockup markSize={22} />For print, export the component at 4× target size and save as SVG from any browser's devtools. The mark is pure geometry — it scales losslessly.
