The previous post was posted truncated. Often I resubmit just for
getting it truncated again. This gives a lot of extra work for both me
and moderators. I get this problem only with .

My last post on velocity of relativistic electrons is also truncated.
I submit new posts on research questions also to
. No problem there.

I recommend readers to get the truncated part of my post " velocity of
relativistic electrons" from that newsgroup.

They claim gravity modifies QM at Planck scale and next compute
different
decoherence times T for different massive objects using Penrose model.

T for single electrons is of order 10^19 years in that model.
Therefore
single electrons will be very well described using QM during all your
life. However, T for a cat [#] is so short like 10^{-37} seconds.

{BLOCKQUOTE [1]
The Penrose-Hameroff proposal suggests that coherent superpositions of
tubulin proteins are inherently unstable and subject to self-collapse
under a quantum gravitational criterion Penrose objective reduction or
OR.}

Notice that their model is basically 'linear' (like most of current
decoherence models). Strong nonlinear models will give different times
and
size scales.

I already illustrated in the other thread how previous generalized
claims
about no importance of relativity and weak interactions at molecular
level
have turned to be in error.

Both mistaken claims were based in naive arguments based in ratios.

[#] On rigor i would say T for a hypotetical quantum object would
decohere
to that mostly classical structure we call cat.
