Ok, but I'm sure you agree it's a pretty accurate measurement.
I must say that I am a fan of the work of Nassiem Haramein, if you're not already aware of him I invite you to take a look at some of his papers. His is an amateur, but works with Post-docs, I like very much his paper of the schwartzchild proton. Take it as you will, but his approach is unique and quite elegant i must say.
Yes the measurement is accurate.
Concerning Haramein: I won't have a look. The ' schwartzchild proton' theory has been debunked and no serious physicists takes him seriously...
No problem, it's good to have another point of view, thanks. I like to keep an open mind however.
It is good to have other viewpoints, but when they are proven to be wrong, we also have to be able to give up on them...
