Repulsive force of matter.

Factual Questions
1

Have cosmologists calculated the value of lamda yet?

I think that is still a matter of research (since it was just discovered in 1998). I’m not familiar with the current range of estimates used in cosmological models and I didn’t find anything from a quick search on the internet. Anyone else?

I have no answer but a quick search turned up a link to this book on cosmic repulsion.

I make no claims to how good of a book this is or how reliable the author is. I didn’t even read the synopsis.

Just thought you might be interested.

Well, there’s been measurements, but they’re not very precise, and they’re somewhat model-dependent. The current best estimates put Omega[sub]lambda[/sub] at about .7 (one significant digit). What that means for lambda depends on the value of H[sub]0[/sub] and I think on the cosmological model, both of which are still disputed. I’ll have to see if I can find an exact conversion.

Sounds about right from what little I can glean from the internet. Here’s the best link I could find…which says 0.75.
