Show HN: The Universe in One Chart

https://saminloes.com/one-chart/
6•atleastoptimal•2h ago
This is an interactive version of the mass-vs-radius chart from Lineweaver & Patel's "All Objects and Some Questions" (2023). It plots the scale of everything in the observable universe on a single log-log chart

This was an experiment in extending the utility of a science infographic via hyperlinks, navigability and tooltips that detail the meaning of specific parts.

There are likely still spatial/numerical issues, happy to take corrections.

The original paper: https://pubs.aip.org/aapt/ajp/article/91/10/819/2911822/All-...
