Thanks,I think I understand that now.Do they travel as as expanding sphere?Gravitational waves travel in all directions at light speed, so yes in that sense. A given wave isn't spherically symmetric (rings as you put it) any more than a propeller in the air creates spherical waves. It creates more like spirals, strong in the orbital plane and weakest along the axis of rotation.QuoteIf so ,is the total energy level on each concentric ring of the sphere the same no matter the distance from the source measurements are made?There are not concentric rings, and the energy is most concentrated in the orbital plane. If you had an instrument capable of measuring Earth's gravitational waves, it would be stronger out by Neptune's orbit compared to the same distance but along the rotation axis of our solar system.
Still, I am still wondering if we can still say that these very asymmetric "rings" carry away their energy without any loss of power at all as they encounter obstacles in their path.
So would a neutron star or another black hole absorb their energy?
Or indeed just any object of any appreciable mass?
Or does the gravitational wave go through these objects as if they were not there?
