LIGO’s Second Black Hole Merger Leaves No Doubt: Einstein Was Right!

Yes, LIGO (no one else) has detected two signals, but not too fast.

Yes, gravitational wave (GW) was verified indirectly long ago. But, GW definitely is not the media (way) for the gravity interaction. GW is at best an attribute of gravity.

Yes, LIGO detected two signals. But, it could well be the collision of two moving currents in the Earth’s liquid core which cannot be detected with the standard Seismometer.

Anyway, LIGO has said much (much, much, …) more than it actually knows.

When the first detection was announced, I had no way to know the nature of the signal, as it could well be a GW signal. But, LIGO’s explanation about two 30 M☉ mass black holes collision is definitely nonsense.

Now, the direction of the event is reported.

One, all telescopes (ground or space based, optical or otherwise) can search the area.

Two, as the black hole is much colder than the space ambient CMB temperature, that kind of event should give some signature in the CMB data.

Three, theorists can now exam the forming 30 M☉ mass TWIN-black holes mechanism.

Thus, I kept my silence at the first detection announcement.

When the second and perhaps the third detection were announced a few days ago, it is now a Bullcrap.

First, no one (not a single person in this world) knows the population density for the LIGO type twin black holes. Only after enough detections, we can then estimate that density. Only after knowing this density, a calculation can then be made to see whether this density can be produced with the known mechanism which produces the black holes via the supernova process (SP). Furthermore, the mechanism for the twin black holes production via SP is not well-understood.

Second, if these twin black holes are primordial black holes, then there must have four sub-issues.

One, if these are primordial black holes (not via SP), they must have some signatures in the CMB data, as they are much colder than the CMB ambient temperature. But, no such signature is found thus far.

Two, if a primordial black hole can have over 30 M☉ mass, then the entire ‘inflation’ idea will be in jeopardy.

Three, we should have some production mechanisms about their productions first before making any big claim.

Third, gravitation WAVE is a wave; that is, it is in RIPPLEs. Yet, thus far, LIGO only detected a single silver bullet (with three contours) for each GW. Until we can detect more than one ripple from the same GW, …

Fourth, if the population (via SP or primordial) of this kind of twin black holes is very high, it must play some very important roles in the ‘Dark Mass’ issue. But, right now, there is no sign of this from any other types of data (Planck CMB, NASA’s Fermi Gamma-ray Space Telescope survey, Dark energy survey, … etc.).

Furthermore, why is 3 M☉ mass in a very small region (less than 1 mile diameter) not becoming a new black hole?

For a science, verification from a different experiment is the minimum requirement for a science claim. The two detectors of LIGO consists of only one experiment. We need data from someone else, such as VIRGO, etc.

Furthermore, we should also verify a claim with different experimental methods. When the event LOCATION can be identified, that region can then be investigated with other means (optical, X-ray, gravitational lensing, etc.).

Today, too many theoretical issues are not addressed, and there is not a single VERIFICATION from other experiments up to this point. LIGO has said much too much more than it actually knows.

In addition to the above simple points, the most important issue is that whether this twin-black-holes STORY can address some simple questions, such as:

One, deriving the Planck CMB data

Two, the hierarchy issue,

Three, the quantum gravity issue,

Yes, GW (gravitational wave) is real, but the LIGO announcement this year (2016) is definitely a bullcrap. And, here is the bullcrap stamp for {LIGO 2016}.

Note (added on June 17, 2017): LIGO announcements must consist of two parts.

One, its detected signals are astrophysical origin.

Two, its interpretation of that signal must be in consistence with the known understanding of the current astrophysics.

I was personally unable to challenge the ‘one’, but it fails to get support from all other astrophysical tools (x-ray, gamma-ray, lensing data, etc.).

My main objection is about the ‘two’. The rate of LIGO’s detection is too high to be in consistence to the current data on the black-hole population-density. And, in G-theory of Planck CMB data calculation, the high black hole population density plays zero role in it.

On 13 Jun 2017, a group of astrophysicists is now challenging the ‘one’; that is, LIGO’s detected signal might not have the astrophysical origin, see https://arxiv.org/pdf/1706.04191.pdf
