LIGO events and Celestial Events


There are coincidences among the 16 LIGO detected events and several celestial events.

4 GW events were nearly coincident with a new moon (within 2 days).

2 events nearly coincided with a full moon (within 2 days).
2 events nearly coincided with a perigee (within 1 day).
1 event nearly coincided with a perhelion (within 1 day).
2 events nearly coincided with an alignment between the Moon and Jupiter (within 2 days).
That means 11 out of 16 were within 2 days of a celestial event.

2 other events were within 5 days of a perigee.

All 16 GW events were within 6 days of a lunar or solar celestial event.

Wikipedia has a list of each GW event date and time

The event names have the format: GWyymmdd
where GW150914 event is on 2015-09-14.

Here is the summary. The details will follow, then a conclusion.

Here are those dates and the concident celestial event: full or new moon: FM or NM or PG (Perigee), PH (Perihelion), MJ (Moon - Jupiter alignment).

difference of 0 days is a match, 1-2 is near, 3-6 is questionable, >6 is too far.

On 2019-04-23 was a alignment separation of the Moon and Jupiter of only 1 degree, 38 minutes, at the same RA.

When I did this exercise I expected no frequent correlations between any moon positions and the gravitational wave events.

I am quite surprised by several coincidences.
A new moon puts maximum tidal stress on Earth's crust, with the Sun also aligned. A perigee also does an earth tide regardless of the Sun.

From Wikipedia:
Earth tide is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer.

With the Moon at such a distance I do not know how many days cover most of its significant crust distortion. Maybe it takes only a day or two to relax. I was surprised by its meter-level amplitude.

This observation is probably a random coincidence of dates.

I really can't argue if someone says you can always find some possible pattern between sets of numbers.

In any case, I find this observation interesting. I leave it to reader to their interpretation.

I checked for these coincidences simply because LIGO was designed to detect any disturbance in Earth's crust from a theoretical gravitational wave. The Moon is known to disturb Earth's crust and oceans.

This means all 16 GW events were within 6 days of a lunar or solar celestial event.

I honestly don't know for certain whether this is an appropriate criteria.

If this observation is valid: this is funny if LIGO did not always account for the lingering effects of the nearby moon.
