Default Speed of Flowing Space (was - Einstein was an...)

"Bill Sheppard" wrote in message...

From Painius:

...what if actual energy of flowing space
is equal to "m" times the speed of
gravity? (or more accurately, the speed
of space itself)...
E = m(c x 2 x 10^20)²
or...
E = mVg²
...where Vg is the so-called "speed of
gravity" (actually the speed of flowing
space)?


As was just stated in another thread, what this is describing is _speed
of gravitational charge_ which is functionally instantaneous
irrespective of distance. This is distinct from velocity of spatial flow
itself. Space flow into Earth's surface, for instance, is equivalent to
escape velocity, or 11.2 km/s (about 7 mps). Same with any celestial
body; speed of inflow at surface datum is equal to that body's escape
velocity.


The speed of gravitational charge, hmm..., or
do you mean "change"?

At any rate, this would make out the speed of
functional gravity to be...

3 x 10^8 x 2 x 10^20 m/s, or

6 x 10^28 m/s, or

60,000,000,000,000,000,000,000,000,000 m/s

That's 60 OCTILLION meters per second!

That's 200 quintillion TIMES the speed of light!

From our frame of reference, we can almost lose the
word "functionally" in "functionally instantaneous"!

Using the Sun and Earth, we know it takes 8.31
minutes (498.6 seconds) for light from the Sun to
reach us. If we divide this by Vg, we get a figure of...

2.5 x 10^-18 second

....as the time it would take for the Sun's change in
gravitational information to reach the Earth.

Now here's where it gets interesting... suppose there
is an object out there about one light year away. We
can't see it because it's, say, a brown dwarf and does
not emit/reflect light. How long would it take for a
change in its position to be gravitationally noted by
our Sun?

Using round figures, this comes out to be...

9.5 quadrillion meters / 60 octillion meters per second, or

0.16 picoseconds!

And isn't it another tickle to realize that any such
influence on our Sun by the nearest stars of the
Centauri group would only take about four times
as long to reach us!

I wanna do one more just for the hell of it, sorry...

The center of our galaxy is roughly 30,000 light
years away. How long does it take the influence
from this tremendous gravity well to be felt by our
Solar System? At the speed of gravity set forth by
Van Flandern...

4.75 nanoseconds!

I'm tired... who wants to figure how many ergs in

E = mVg² ? g

happy days and...
starry starry nights!
