Apparently LIGO technology can detect the far Less Frequent LARGER Mergers
compared to future Space Based LISA
according to this chart their sensitivity to various Frequensies do Not overlap much if at all. **

If the Radius of the Earth shrank due to loss of rotational Centrifugal forces Pulling outward ( like a Merry Go Round stopping)
we would feel a little bit Heavier on the surface; especially at the Equator .
and All the Mantel and Cores would be subjected to increased Pressure leading to...
If the Earth stopped spinning
then the Centrifugal Force FIELD would disappear.
If these Centrifugal Forces were gone, the Volume and Diameter of the Earth would shrink
because Internal Pressures would slightly increase the Density of the Mantel and Cores, imo.
Early Mathematical Models of...
The FORCE of Gravity we feel on the Surface is 'roughly' defined as 1 G.
It varies slightly from 1 G locally, especially around the Equator and Poles as discussed above by others.
Gravity is a 3D FIELD that varies
from ZERO G at the Center of the Earth
to One G at the Surface
1 G causes...
Thanks for the clarifications above.
I also saw that an "accretion disc' acts like a 'traffic jam' or 'firewall' as some have described it ;
Before any gas or dust can even reach the EH.
Apparently 'spaggetification' also happens outside the EH due to the tremendous G gradient ??
More dramatic Views of 2 Neutron Stars as they 'Ringdown' into a Singularity.
Seems some portion of the Fuel Rich remnants of these 2 stars
would reach Critical Mass conditions Inside the Event Horizon
so their released Energy in the form of Light photons etc..
would be Trapped by the BH ?
I did find an Estimate, that the space based eLISA proposed for launch in 2034,
could detect as many as 35 GWave events over a 3 Year period from MASSIVE Bianary Black Hole Mergers
with another 55 less Massive mergers at too high frequencies to be observe by eLISA.
This higher Estimate of ~10...
I am pretty sure I read they expect maybe 1 BH Merger event Per Year, but can not find the article.
I'll keep looking
I was wrong about it being thousands of Light Years away. It was over 1 BILLion Light Years out there.
I did find this article that says the GWave carried away 3 Solar Masses...
Apparently we can expect this experimental Result to be repeated about Once every year ?
Gravitational Waves are the Result of the rapid Acceleration of Mass that is distributed unevenly, ie nonSpherical ?
apparently this Configuration of Matter is predicted by GR to be a QuadruPole
As I...
The Model I found most feasible to generate a GWave and GRBurst
was the Merger of Two Large Stars.
As Yen and Yang merged, their combined Gravitational Field caused
each to collapse into 2 counter rotating Black Holes
which then formed a rotating QuadroPole which generated the GWave
seems the...
Thanks for Parameterizing the difficulties involved in Locating this hypothisized Planet9.
Sounds like the Mathematicians will have to narrow the search area using Gravitational anaylsis.
Also sounds like a High Resolution Space Based Telescope may be needed to provide enough background...
You're correct, the Diameter is probably smaller than I first imagined. Most of planet 9 is probably liquified or frozen solid 'gases'.
Still seems like some Star will be seen to Dim or Disappear as Planet 9 slowly eclipses its view from Earth.
This is how small Near Eath Objects and very...
""Centrally symmetric mass distribution cannot emit gravity waves even when changing.
The asymmetry of a Binary black hole Merging is what produces changing quadrupole moment and allows emission of gravity waves.""
quoted from above.
The rapidly spinning and orbiting Binary BHs were descibed...
Planet 9 is supposed to be 10 Earths in Mass.
It's Diameter is probably greater than 10X ;
especially if it's gaseous like Uranus.
Something as big as Planet Nine should make Stars blink as it briefly eclipses their view from Earth.
Wide Array low power telescopes take Time Lapse pictures...
