I have presented, cannot be ignored, evidences after evidences why there is no black hole which no light can escape, thus, is invisible.

No, you  did not.

Trying to tackle the intriguing issue whether black hole is real because IT is ACTUAL is one of the biggest challenge in modern astronomy.. Surely EHT, NASA, as well as other respected astronomical societies  have read in passing the brief posting (re-Inviting comments from NASA, EHT that Black hole is just a super- giant boiling object in space…) which Naked Science, kindly, posted  in Google. I have presented, cannot be ignored, evidences after evidences why there is no black hole which no light can escape, thus, is invisible. Hope you will  re-post that article forum  to Google. (Again regards and thank you for being concerned when undersigned was sick. But now, he is recovering, hope so)  Jsaldea12 feb. 17, 2019 

Do you honestly think they monitor google and this site so they can respond to the ideas of some crank?

Can you repute the proofs/ evidences I presented? It  is just that it is hard to accept the truth. there is no black hole.  jsaldea12  Feb. 17, 2019

Due to your English, I can barely understand what you are trying to present. It seems pretty clear from what you have written and from your replies to Kryptid's helpful information, that you do not understand how LIGO actually works.

[Bored chemist]

...which Naked Science, kindly, posted  in Google.

So, you also don't know how Google works.

Wouldn't it be better if you stopped posting stuff until you actually learned how things work?

[Kryptid]

Can you repute the proofs/ evidences I presented?

We already have. LIGO unambiguously detected the collisions of black holes.

[jsaldea12 (OP)]

Why do you say that the detected speed of gravitational waves and light waves, both with electro-magnetic property, on ejected super heated  jets of super-galaxies are the same, and if both are detected , how do LIGO re- assure that both have same speed of light. Final query:  why do you say that the same speed of gravitational waves and light waves  affirm  black hole. LIGO never said that ..  jsaldea Feb. 18, 2019.

How LIGO works? I KNOW!!! jsaldea12Feb. 18, 2019.

[Kryptid]

Why do you say that the detected speed of gravitational waves and light waves, both with electro-magnetic property,

When were gravitational waves ever demonstrated by experiment to have electromagnetic properties? Please don't try to use your own hypotheses as evidence, because they aren't.

on ejected super heated  jets of super-galaxies are the same, and if both are detected , how do LIGO re- assure that both have same speed of light.

There are multiple detectors involved. Measuring the difference in time involved between detection at one site and another site allows for calculation of speed.

Final query:  why do you say that the same speed of gravitational waves and light waves  affirm  black hole. LIGO never said that ..

LIGO never said that and neither did I. It's the particular pattern that the gravitational waves exhibited that demonstrate that black holes are what produced them. I have a book on this subject written by Kip Thorne from 1994 that describes what a signal from a black hole merger would like if detected by a gravitational wave detector. So we have known for quite some time exactly what it would look like.

It was respected Forum King Kriptid who said: “Thanks to LIGO and VIRGO, we know that black holes exist because of their unique gravitational wave signayure” . Nevertheless both  have inherent positive and negative property, the same inherent positive and negative property of spacetime. Reiterating, transmission of radio signals, TVs signals, thru the air, thru undivided property  of spacetime but upon receptions by antennas, directly to internet cables, etc. both positive and negative separate otherwise no radio, no tv, no internet. Astronomical telescopes from two separate places, 2,000 miles away, provide the data, feed it to laser interferometers underground tunnels, arms,some 2,000 miles long, completely emptied of air, thus vacuumed  The point is all the way after astronomical telescope pick up the collision of galaxiy, to the arms of interferometers, to photo detector, light is being used, laser. Because light waves and gravitational waves are the function, the making of waves on the fabric of spacetime and inside the arms of laser interferometers,  is the all-encompassing fabric of spacetime.. But why does the super-jets, super-heated,jettisoned from super-galaxy become the signature of black hole. Because of super-compaction, super-gravitational force exerted to eject that jet.? But the SAME giant object, not a supposed black hole,  can eject same jets!! . Jsaldea12  feb. 18, 2019.

By the way, I knew respected Dr. Kip Thorne, unfortunately, he never responded, just received..

Forum titles here are automatically given based on post count. If you are implying that I am calling myself a "forum king", then you are mistaken.

I'm sure I've asked this before, but what are these positive and negative properties you are talking about?

Astronomical telescopes from two separate places, 2,000 miles away, provide the data, feed it to laser interferometers underground tunnels

You've got it backwards. The interferometers are providing the data.

arms,some 2,000 miles long, completely emptied of air, thus vacuumed 

The arms are not 2,000 miles long. They are only 4 kilometers long.

The point is all the way after astronomical telescope pick up the collision of galaxiy

They aren't detecting the collision of galaxies, they detecting the collisions of neutron stars and black holes.

Because light waves and gravitational waves are the function, the making of waves on the fabric of spacetime

You have yet to establish that light waves are function of the fabric of space-time.

But why does the super-jets, super-heated,jettisoned from super-galaxy become the signature of black hole.

They aren't the signature of the black holes that LIGO is detecting.

But the SAME giant object, not a supposed black hole,  can eject same jets!!

That has nothing at all to do with LIGO's gravitational wave detections so it's irrelevant.

Have you realised why he did that?

Let us stick to issue: Why do you say that the collision of two black hole is proof of existence of black hole? jsaldea12 Fedb. 20, 2019

[jsaldea12 (OP)]

Ah forget my grammar, just read between the lines.. jsaldea

[Bored chemist]

Why do you say that the collision of two black hole is proof of existence of black hole?

Because, if they did not exist, they could not collide.

How did you not understand that obvious fact?

[Bored chemist]

It is pretty obvious from your posts that you are not any kind of scientist. Your grammar and spelling is also appalling.

Did you mean "Your grammar and spelling is are also appalling"

It's really not the issue.

The problem isn't grammar, the problem is comprehensibility.

You can read what lead LIGO to conclude it was a black hole merger here: https://arxiv.org/ftp/arxiv/papers/1602/1602.03837.pdf

Here are some quotes of interest from the paper:

The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0 × 10⁻²¹. It matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. Over 0.2 s, the signal increases in frequency and amplitude in about 8 cycles from 35 to 150 Hz, where the amplitude reaches a maximum. The most plausible explanation for this evolution is the inspiral of two orbiting masses, m₁ and m₂, due to gravitational-wave emission.

The basic features of GW150914 point to it being produced by the coalescence of two black holes—i.e., their orbital inspiral and merger, and subsequent final black hole ringdown.

Estimating f and f_ from the data in Fig. 1, we obtain a chirp mass of M ≃ 30M⊙, implying that the total mass M ¼ m₁ þ m₂ is ≳70M⊙ in the detector frame. This bounds the sum of the Schwarzschild radii of the binary components to 2GM=c² ≳ 210 km. To reach an orbital frequency of 75 Hz (half the gravitational-wave frequency) the objects must have been very close and very compact; equal Newtonian point masses orbiting at this frequency would be only ≃350 km apart. A pair of neutron stars, while compact, would not have the required mass, while a black hole neutron star binary with the deduced chirp mass would have a very large total mass, and would thus merge at much lower frequency. This leaves black holes as the only known objects compact enough to reach an orbital frequency of 75 Hz without contact. Furthermore, the decay of the waveform after it peaks is consistent with the damped oscillations of a black hole relaxing to a final stationary Kerr configuration.

The LIGO detectors have observed gravitational waves from the merger of two stellar-mass black holes. The detected waveform matches the predictions of general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. These observations demonstrate the existence of binary stellar-mass black hole systems. This is the first direct detection of gravitational waves and the first observation of a binary black hole merger.

Kip S. Thorne had this to say about gravitational waves coming from a black hole merger in his book "Black Holes and Time Warps", published in 1994:

If we can decipher it, the ripples' symphony will contain a wealth of information:

The symphony will contain a signature that says, "I come from a pair of black holes that are spiraling together and coalescing." This will be the kind of absolutely unequivocal black-hole signature that astronomers thus far have searched for in vain using light and X-rays (Chapter 8 ) and radio waves (Chapter 9). Because the light, X-rays and radio waves are produced far outside a hole's horizon, and because they are emitted by a type of material (hot, high-speed electrons) that is completely different from that of which the hole is made (pure spacetime curvature), and because they can be strongly distorted by propagating through intervening matter, they can bring us but little information about the hole, and no definitive signature. The ripples of curvature (gravitational waves), by contrast, are produced very near the coalescing holes' horizons, they are made of the same material (a warpage of the fabric of spacetime) as the holes, they are not distorted at all by propagating through intervening matter- and, as a consequence, they can bring us detailed information about the holes and an unequivocal black-hole signature.

Correction: The  arm length, each, of LIGO is 4 kilometers. Forget that remark  with respected Dr. Kip Thorne.

Respected EHT has not yet made an official statement whether that object at the core of Milky Way is truly invisible that light annot escape.

Here iare further evidences: That the blown out fire-blast dust and gas, originating from the boiling core of Milky Way, extends far out from the limitng  EH, proves it escapes with light. That the speed of light and gravity are the same ,  both, goes, hand in hand, ourtward into space is  emperical evidence of the unwritten law of physics which states where there is fire, there is light... jsa 2.22.19

Respected EHT has not yet made an official statement whether that object at the core of Milky Way is truly invisible that light annot escape.

So what is your contention, exactly? That black holes do not exist or merely the lesser claim that the object at the center of the Milky Way (Sagittarius A*) is not a black hole?

That the blown out fire-blast dust and gas, originating from the boiling core of Milky Way, extends far out from the limitng  EH, proves it escapes with light.

What evidence do you have that it came from inside of the event horizon?

[jsaldea12 (OP)]

Do read all my postings why the dust and gas completely covering supposed black hole is itself the making of that supposed black hole.!! Nearly all the photos shown in the internets showing  black holes at the center of galaxies are artist perspective. All galaxies , actual, have total dust and gas covering all over centers of galaxies. No matter how more EHT will add more astronomical  telescopes, to get higher resolutions, they will  always see  actual image of  gas and dusts., why because light is the carrier of image and informations, and light can not penetrate the dust and gas!!!.
In 2004, Stephen Hawking and Kip Thorne had arguments because Hawking declared no EH and Throne contends there is. Jsa 2.23.19
