Jeff,<br><br> Love your mind. Before going on, it
strikes me that I left out a crucial element of the
equation: the value of b. For every 1000 KM/second of
escape velocity b increases by 0.0066335 in case you
want to do your own 'plug and crank.' Speaking of
plugging and cranking, would you have shift data for
Sirius? It would be a way to refine b in at least one
local case. I can convert Z to an ORV and l have the
distance here. I had to stare at the Time of Flight
equation for some time to convince myself of how it works.
If b is zero and ORV is zero, the Time of Flight is
zero and as the ORV gets large, the ToF goes to 1/m
which is how it should behave. I have generally avoided
using equations for the same reason that Hawkings did
in 'Brief History ...", it cuts down
readership.<br><br> You boiled down the discussion quite nicely when
you said:<br><br>"One of the possible benefits of
this research would be a confirmation (or denial) of
the straight line relationship between red shifting
and speed of recession. Therefore to shelve
discussion of such research when there seems to be a
realistic possibility that it will yield a confirmation (or
denial) of the basic assumption used for long distance
measurement would seem to be a big mistake."<br><br> Or at
least half way you did. It is the interpretation of
shift as movement that is the other half. One needs two
good distances separated by time in order to discern
line of sight movement. Unless one uses a tool like my
spherometer, you can't get good distances. Unless you have
angular measurements; then you can at least set an upper
limit on the distance. Now if distance were linear with
shift this subclass of type 1A SNe, ones with long
periods and high shifts, would not, I offer, be something
which would be of observable angular dimension. But the
galaxies with which they are associated would. Are we
given even that? Remember, we have 60 (or more) to
choose from. From one side, we have quite a few good
distances to galaxies of known types and angular dimension.
This would amount to having some grip on their
diameters. Even if galaxies' sizes are only roughly similar
to one another (within a type), knowing that angular
dimension falls off directly with distance gives a double
check to compare distance vs. shift. This, too, would
offer "a realistic possibility that it will yield a
confirmation (or denial) of the basic assumption used for long
distance measurement would seem to be a big mistake."
Would you happen to know if this has been done? If not,
could it be "If these objects are in fact far closer
than assumed and this can be proven by other methods,
then we have a new objection or a major problem with
the Standard Model."?<br><br> Failing the 'angular
dimension' test, we have nothing to go on except the
expectation set which is the "Standard Model." At least not
until we have another way to put distances to these
objects. But what if we do get good distances and the
times of flight correspond to the equation I presented
in my last letter? What would that mean in terms of
Astrophysics and the thousands of careers invested in the
movement issue? Do you suppose that this would clear up
immediately or not? A friend of mine was talking to an
Astronomy professor who said "but if the BBT is wrong, then
all bets are off."
