How to explore Light Cone 3D Explorer
Open the Light Cone 3D Explorer, read c = 299,792.458 km/s and the 45 deg null-line literacy, then scrub a probe event across past, future, and elsewhere.
- Open https://freetoolonline.com/space-3d/light-cone.html and wait for the green future and orange past cones.
- Read the facts panel: c = 299,792.458 km/s, 45 deg null lines, causal regions.
- Scrub Event x and Event ct; watch the causal label change.
- Press Snap to null ray, then toggle Future / Past / Elsewhere layers.
- Compare with Gravity Well 3D when you need escape-velocity wells instead.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
