The Spaceline: a space elevator alternative achievable with current technology

Ok, I didn't read the paper...

But everyone knows the moon orbits the earth with a cycle sort of similar to what we call a month.

How is an earth-moon cable feasible again?

Suggestion - read the paper.

"The Spaceline. By extending a line, anchored on the moon, to deep within Earth’s gravity well"

That's the concept. They could have fit that within in the title of the post.

A pointer to where they compute this in the paper would be helpful. There are a lot of comments to just read the paper because they calculate this or that, but I quickly read the thing through and either missed all these points being covered, or it's not actually considered.

I assume it's not anchored to the earth

Wouldn't be much use if it wasn't.

well… you should read the paper, or maybe a summary like this one[0], before jumping to comment.
