This? This? This? It's a lot easier if you provide links with references.

There's a fairly narrow band of trajectories that will give a free return to Earth, yes. They plan for mid-course correction burns to...

That's true, but that hypothesis is not the same as Wheeler's "one electron" hypothesis. In quantum field theory--or more precisely...

I think this is a good idea. Feel free to ask questions again when you are ready. I might not be able to help with them, but others might.

Did you read my post #39 (which Cerenkov quoted)? Do you have specific questions about what it said?

Start a new thread, quoting whatever particular things in the Insights article you want to ask about.

Did you actually read the post of mine that you quoted? You quoted it, but you didn't actually ask any questions about what it said. You...

I'm not sure how much more basic you can get than the diagrams themselves. Maybe someone else has a bright idea of how to simplify...

It doesn't. As @PAllen said, the topology of the initial singularity for the open (and flat, though I don't think he included that case...

No, that is not correct. The measurements commute--that is, their results do not depend on which one occurs first. (This has to be the...

The diagrams in Davis & Lineweaver show the difference. In terms of comoving distance, any two comoving observers are a constant...

No. Please read my posts #26 and #30.

You might be conflating proper distance and comoving distance. I tried to disentangle at least some of that in post #26 in response to...
