Mach's Principle and Negative Gravity |
I've had a thought. (It occasionally happens.) If Mach's Principle is
true, and the origin of inertia is (cosmological) gravity, then --
The expansion of the Universe due to a strong negative factor in
Einstein's gravitational equation -- couldn't happen. It would mean a
preponderance of negative (vacuum-stressed?) gravity in the
cosmological gravitational field.
But, via Mach's Principle, this would give negative inertia. The
slightest push on material objects wouldn't be resisted, but assisted
(handy in pushing heavy loads around), and they would speed up to the
speed of light.
And since they don't, I conclude that the Universe isn't accelerating
(at least, due to gravity).

Is n't thats whats happening - everything is flying apart and
accelerating?
Get ready for the big rip where the earth will be ripped apart,
followed by electrons stripped off atoms etc.
Perhaps everything has negative mass so that it has positive inertia
:-)

Maybe that's where photons came from -- particles of negative inertia
that speeded up to c.

Watch we don't get sucked down that galactic black hole first!

Nice idea, however the inertial mechanism in Mach's Principle is not
well defined.
It could be that the mechanism would work even if there was only
anti-gravity.. a change in the velocity of a mass will might still add
the same energy to the gravitational potential and so will be resisted.
To put it another way, a push from all sides could have the same
effect as a pull from all sides.

Too Many, they already acquire such an inertia beyond the universe's
event horizon. However, the space between superclusters and voids are
great, and there are already nice gamma ray bursts that are evidence of
our predictions.

If the inertia-inducing ability of mass increases with its
relativisitic increase of mass, due to its cosmic recession velocity
.....
What on Earth (or wherever) would be the effect of mass BEYOND the
horizon??!!

I don't believe in mach's principle
Mass is local. And mass does the resisting.
The outward acceleration could be
considered anti grav.

It would be overall collapsing, of course, though locally it'd repel by
gravity. We might even borrow (nah, steal) endless energy from the
interface by tunnelling some hither.

Well, assuming for the sake of argument that the "mechanism" is a
transverse force -- a relative transverse wave -- caused by a test mass
cutting across lines of "cosmic background" gravitiation. Like the
analogous force experienced by a test charge accelerating across
electric field lines.
Now in the electric case we have, handily, both attraction (between
unlike charges) and repulsion (between like charges). Presumably, the
transverse accelerational force acts in one direction in the first
case, and the opposite direction in the second.
And possibly it is similar for gravity, mais oui?

You're not considering the fact the our visible Universe is but a
subsystem of the Whole Shebang Universe (WSU), ewe know, you must
include the part beyond the causal horizon, which all forms the General
System, and then beyond the General System
is.....is......is.....is.....
AAAAAAAHHHHHHGGGGGGG!!!!!
BLAM!!!!!!!!!!!
