On Black Holes and Amazing Discoveries


In 2019, astronomers using the Event Horizon Telescope system announced that they had captured what they described as the first ever image of Black Hole


Black Hole discovered in far-off galaxy?
“A Black Hole has been photographed at the centre of the galaxy M87, 55 million light-years from us. It's now been named Powehi, a Hawaiian phrase referring to an "embellished dark source of unending creation.”


Steve Crothers* begs to disagree...

It is not a discovery at all.

Rather, this is how astronomers and cosmologists do science: fraud by means of mass-media induced mass-hysteria. It beggars belief. Think about it: according to the astronomers and cosmologists the finite mass of their black hole is concentrated in a 'physical singularity' of zero volume, infinite density, and infinite gravity. But no finite mass has zero volume, infinite density, and infinite gravity, anywhere!

Similarly, the astronomers and cosmologists assign to their black hole two different escape speeds: one of zero metres per second and one corresponding to the speed of light of 300,000,000 metres per second, and this in the same equation! At the same time there is no capacity for an escape speed (since nothing can even leave), simultaneously, at the same place (at the 'event horizon' meaning the boundary of a black hole beyond which nothing can escape from within it.). But nothing can have two different escape speeds and no capacity for an escape speed, simultaneously, at the same place! Furthermore, the astronomers and cosmologists assert that the escape speed at the event horizon is the speed of light, yet light cannot either leave or escape; indeed, nothing, they say, can even leave the event horizon. But since light travels at the speed of light, which is the escape speed at the event horizon, light must both leave it and escape! And, moreover, anything else can leave.

On the mathematical level, the black hole is conjured by violations of geometry. Geometrically speaking, the theory of black holes moves a sphere originally centred at the origin of a coordinate system to some other place in that same coordinate system but leaves its centre behind. By this means the two 'singularities' of the black hole are produced, the centre of the moved sphere, now thought to be an event horizon, and the left behind centre at the origin of coordinates, thought to be the 'physical singularity'. According to Black Hole theory, In the centre of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.

Analytically speaking, the violation of geometry manifests in black hole theory as the requirement that the absolute value of a real number must take on negative values – which is impossible as I’ve argued in detail elsewhere. (For example, in a paper for Hadronic Journal called ‘On Corda’s “Clarification” of Schwarzschild’s Solution’).

The laws of thermodynamics require that temperature must always be an intensive thermodynamic property. (The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases. ) To argue otherwise is a violation of both the 0th and 2nd laws of thermodynamics. The Hawking temperature of a black hole is however non-intensive, in violation of the laws of thermodynamics. (Stephen Hawking argued that quantum effects allow black holes to emit exact black-body radiation and that the electromagnetic radiation would be produced as if emitted by a black body with a temperature inversely proportional to the mass of the black hole.) So black hole thermodynamics is entirely nonsense as this video on the subject of Gravitational Thermodynamics demonstrates.

The conclusion must be that the black hole does not exist; proven with common sense and high-school science. Yet the astronomers and physicists have managed to image that which does not exist. To which we might say, of course they did - they have to justify their lucrative jobs and their vast grants of unaccountable public money.

Picture Post #20 Olber's Paradox raising insoluble questions



'Because things don’t appear to be the known thing; they aren’t what they seemed to be neither will they become what they might appear to become.'


Posted by Martin Cohen and Tessa den Uyl

A NASA  image from the Hubble Telescope looking into the 'Deep Field'
This is a patch of BLACK sky - empty when initially seen - even through the largest earthbound telescopes. Yet, with the  Hubble space telescope and a long-enough exposure time, even the darkness of space soon comes to glowing life. The point is, every bit of sky is actually packed with light - not merely with stars but with uncountable distant galaxies.

Heinrich Olbers (1758–1840) was a Viennese doctor who only did astronomy in his spare time, but realised that there was a bit of a logical problem about the night sky. And ‘O’ is for ‘Olbers Paradox’*,  which can be summed up by saying that if the universe is really infinite in size, the the night sky should not only be bright – but should be infinitely bright. Put short, we should see stars everywhere we look. So why don't we and why isn't the night sky all lit up ?

The paradox touches upon profound issues in cosmology, or the study and theory of the origins of the universe. Simply saying that most of the stars are too far away to see is not enough. Certainly it is true that starlight, like any other kind of light, dims as a function of distance, but at the same time, the number of light sources in the ‘cone of vision’ increases – at exactly the same rate. In fact, on the mathematics of it, given an infinite universe, with galaxies and stars distributed uniformly, the whole night sky should appear to be not black, not speckled, but white!

Olbers’ paradox is a ‘thought experiment’ in the very good sense that most of the reasoning is done by hypotheticals. What if the universe is infinitely large? And infinitely old? If the stars and galaxies are (on average) spread out evenly?

Various possible explanations have been offered to explain the paradox. Such as that stars and galaxies are not distributed randomly, but rather clumped together leaving most of space completely empty. So, for example, there could be a lot of stars, but they hide behind one another. But in fact, observations reveal galaxies and stars to be quite evenly spread out.

What then, if perhaps the universe has only a finite number of stars and galaxies? Yet the number of stars, finite or not, is definitely still large enough to light up the entire sky…

Another idea is that there may be too much dust in space to see the distant stars? This seems tempting, but ignores known facts. Like that the dust would heat up too, and that space would have a much higher. The astronomers who took this image claim it shows some kind of spectral shift into the red specturm. Or is it only the dust? The questions are not really resolved, even yet.

So what is the best answer to Olbers’ riddle? The favoured explanation today is that although the universe may be infinitely large, it is not infinitely old, meaning that the galaxies beyond a certain distance will simply not have had enough time to send their light over to fill our night sky. If the universe is, say, 15 billion years old, then only stars and galaxies less than 15 billion light years away are going to be visible. Add to which, astronomers say that the phenomenon of red shift may mean some galaxies are receding from us so fast that their light has been ‘shifted’ beyond the visible spectrum.

After reading this, and then standing here on planet Earth and watching the night sky, one might feel a little trapped by the questions. Our sight is limited and it always will be but maybe this is our hope for we can continue to philosophise: afte rall, what are we thinking? The picture above might as well represent pieces of coloured glass, under water visions where fluorescent life flows in deep dark sees, a pattern for printed cloth. Our brain only represents what we think we see, not necessarily the reality in which we live? In the incredible immensity of space, mankind has always been aware of this, even if, once in a while, the tendency is to forget.


* Although the paradox carries Olbers’ name,  it can really be traced back to Johannes Kepler in 1610.  In Wittgenstein's Beetle and Other Classic Thought Experiments, Martin’s book, which talks a little more about all this,
