So nutzen Sie Raumzeit-Kruemmung 3D Explorer
Open the Raumzeit-Kruemmung 3D Explorer, read r_s = 2GM/c^2 with Sun ~2.95 km, then switch Earth / Sun / 10 Msun BH to deepen the teaching grid.
- Open https://freetoolonline.com/space-3d/spacetime-curvature.html and wait for the curved grid and teal geodesics.
- Read the facts panel: 2GM/c^2, Sun ~2.95 km, Earth ~8.87 mm.
- Press Earth, Sun, and 10 Msun BH to compare depth.
- Toggle geodesics and the exaggerated r_s ring.
- Compare with Gravity Well 3D for escape velocities, or Light Cone 3D for flat causal regions.
Next: the when guide or vs alternatives. Open the Raumzeit-Kruemmung 3D Explorer.
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.
