Sorry boy, you are of the opinion that it is ok to support something without knowing it, so I doubt about your knowldge on these subjects. You more or less display herd mentality, which is mostly of nuisance value.
LOL... Please Register or Log in to view the hidden image! Could you design a CPU? You seem to be OK with trusting the physics behind your computer without understanding it. I only know a bit about physics which means my knowledge is orders of magintude beyond yours. You display that strange mentality where you are ignorant of a subject and yet maintain that the experts are wrong, which is pitifully sad and funny at the same time.
Certainly, I cannot doubt about your bit knowldege of physics. Now, please tell what is barycentre...
Are you joking? Let's assume I had no idea what a barycenter was - it would take about 30 seconds to find out on google.
Ok, let us assume that you have some idea about barycentre... Now please try defining the same in GR.
I have no idea how to use General Relativity to calculate the barycenter of 2 orbiting bodies. The definition is the same, which is the point that 2 bodies orbit around.
