How many of yous believe that there was actually A Detection Of Gravitational Waves? raise your hands. oh, my...so many fools here. I have a bridge to sell you..

Perhaps your question is: Are gravitational waves in specific circumstances other than spherical? Check your general relativity textbooks. -- sci.physics is an unmoderated newsgroup dedicated to the discussion of physics, news from the physics community, and physics-related social issues.

That is an impossible claim. What nucleus did we use to detect that? It is more reasonable that we can't do that.

Observing an interference pattern of two light waves that produce no
interference pattern when there is no (extra) strain. Since none of the
several videos¹ explaining this can be displayed here, and for recreation,
new ASCII art by me (simplified, exaggerated, not to scale):
No strain Strain
(as with GW150914)

It is not. In fact, the maximum measured strain was even smaller than the
diameter of a proton (< 1.68 × 10⁻¹⁵ m).

None.
