When to Use Dark Matter Rotation Curves 3D Explorer - Best Sessions and Limits
Open the Dark Matter Rotation Curves 3D Explorer when you need to teach or review the rotation-curve evidence for dark matter - without running a gravitational simulation.
A five-minute classroom demo
A five-minute classroom demo starts when you open the explorer, drag the radius slider through about 2, 8, and 20 kpc while students read the observed-versus-predicted numbers, then toggle the halo off and on to separate the measured curve from the inferred mass.
Separating measured facts from illustrative modeling
Separating measured facts from illustrative modeling gets easier when you compare the observed-curve figures - direct Milky Way measurements - against the predicted curve, which is an illustrative Keplerian-decline shape rather than a per-galaxy measured number.
Sessions Dark Matter Rotation Curves 3D Explorer does not fit
Sessions this page does not fit are precise dark-matter density-profile fitting, N-body galaxy simulations, or what a galaxy looks like visually. Use Galaxy 3D Explorer for a freely spinnable generic spiral shape, or Milky Way Map 3D Explorer for the labeled top-down arm map. Walk the controls in the Dark Matter Rotation Curves 3D Explorer step-by-step guide.
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.
