I think it’s correct as-is. Inserting a “were” would make that clause read as independent. With how the sentence is currently structured, that doesn’t work.

That’s not to say you couldn’t have

The tracks are now unruley [sic] and wild—the people once tied to them were killed in crosswalks by giant trucks

if you want, but the comma needs to change to something like a dash or a semicolon. With a comma (i.e., as a subordinate clause), “were” doesn’t make sense.

Because he defederated them?

WebPlotDigitizer! It’s a great tool.

The object doesn’t absorb their mass, but rather their energy (which admittedly can be equated to a mass via a factor of c^2, but that’s not actually what’s happening). The change in momentum that results from a photon hitting you isn’t caused by a change in m, it comes from a change in v. If mass were the quantity being transferred, solar sails wouldn’t work to move anything; they would just sit there and get more massive as photons hit them.

Here is my attempt at digitizing that plot and then log-scaling the vertical axis.

I’d like to see a Linux board in the Pico form factor, using Risc-V
