Old ideas of space, with real data in support.

The site said:

'However, the transmission mechanism of gravity is continually being
sought - almost certainly in vain'

There is no transmission mechanism to seek - space-time curvature and
gravity are one and the same. Typical crackpot rubbish of flawed logic
based on misunderstood concepts.

Thanks

Forget the snipped rest, but this statement might be not correct.
Space-time curvature is caused by both gravitation and electromagnetism.

The Hilbert action is integral sqrt g R dv dt to which the source part is
added. Variation of the Hilbert action gives sqrt g G var guv. Variation
of the source part gives -sqrt g T var guv by the modern definition of T -
the stress energy tensor. Thus G = T - the modern definition of the stress
energy tensor guarantees it. Thus space-time curvature is 'caused' by the
stress energy tensor which could be all sorts of things - EM fields, matter
etc. What is not part of that source term in the lagrangian is gravity
itself. Indeed from the modern definition of stress energy tensor -G is in
fact the stress energy tensor of gravity itself - if it was a legit way of
looking at it - which I doubt.

Thanks
Bill

Henry Haapalainen:
Space-time curvature is a good abstraction of the truth. But it can not be
the final answer. Falling space leads to same "geometry" of space, and there
is a chance that it may be the truth. If there is some mistake, let's work
together to find it.

I have read your link, and to be frank, you have no idea what your talking
about - I seriously doubt you even understood what I wrote.

That may be nice and good, but I have practically calculated with
this stuff. All results demonstrate that gravitation & electromagnetism
equally go into metrics, and do never mingle. In which, gravitation
is _not_ part of the Ricci or Einstein tensor, and comes from the
integration constants of R_{ij} = 0 .

Dear friend,
the term "fall" has been defined for a body.
Thus, a space does never fall *per definitionem* .

Sorry but do not understand what you are trying to say. I must be stupid.
