Re: Universal grammar

The problem is, when doing such analyzing, what equations to use, and how
to verify them via physical experiments. There is currently no such
physical feedback for constructing a truly unified GRQM, so what these
guys do is creating speculations in settings where both GR and QM may play
a role play, but where these theories act independent of each other. This
includes the Hawking radiation: he assumes a GR sharp horizon, and
a particle pair immediately and outside this sharp event horizon, and
shows that under such circumstances, some energy may escape the black
hole. Without QM, a black hole produces a singularity, but that is likely
to go away when GR and QM have been properly unified. Then strange time
phenomena will go away. Then one would expect that
throwing something inside the black hole will crush it into smithereens,
just some physical invariants being preserved. Also, one has observed some
starts to be absorbed by the black hole at the hub of our galaxy, the
Milky Way, so there is some observational evidence of the phenomenon. And
I think that QM tunneling may allow particles to leave the black hole,
which will admit considerably larger amount of mass to leave them than any
Hawking radiation; but the description of such a phenomenon will require a
QRQM going beyond the unified filed theories experimented with now. And as
for the expansion of the universe, that is just an interpretation of GR -
if now GR must be modified to weaken at large distances, what will happen
with this particular interpretation?

As I didn't study physics I can't discuss these topics much
further. I just see Goethe's world formula "all is equal, all
unequal" take over. Mathematicians and physicists believe
they had eliminated, or in any case tamed, ambiguity. Now
it returns via the black hole information paradox. People
will spend hundred more years taming the new ambiguities,
and when a genius solves the problem by means of a
revolutionary theory based on information, apparently more
fundamental than matter and energy, someone will ask
a funny question, and a new paradox will raise from a
previously unsuspicious corner. It goes on and on. If we
can learn one thing from the history of the sciences, then
this. The mountain grows while we are climbing. We are
always just below the top. One more common effort and
we shall make it - happy illusion that blissfully enchants
every young generation.
