Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

Thermo-Demonics
A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. This long-sought image provides the strongest evidence to date for the existence of supermassive black holes and opens a new window onto the study of black holes, their event horizons, and gravity.

Official press announcement.

On 10 April, astronomers revealed the first ever image of a black hole event horizon -- the surface beyond which light cannot escape from the hole's grasp -- taken by the Event Horizon Telescope (actually a network of telescopes around the world).

You can watch the English language press conference from Brussels live:

This am a computer contrived graphic. Notice there am no difference between the black surface area surrounding the hole and the black surface area of the supposed hole itself. In order to produce a graphic, the computer has to be programed to depict surface using a finite number of finite colored pixels. The computer has also to be programmed to depict light using a finite number of finite colored pixels. The problem am that only VISIBLE surface has ever existed or will ever ETERNALLY exist. There has only ever been one unified VISIBLE infinite surface ETERNALLY occurring in one infinite dimension that am always mostly illuminated by finite non-surface light.

Dear Dr. Kuhn,

On April 9, 2019, FQXi.org published the TOPIC: Black Hole Photographed for the First Time: EHT Announcement, and provided video of the supposed first view of a black hole sighting.

I sensibly posted this second comment at the site and on my own Facebook page:

This is a poorly made cartoon that the Walt Disney Studio would never have allowed to have been released for public viewing.. As for the absurd claim in the video that Albert Einstein was ever thoughtful; nothing could be further from the truth. Every physicist who has ever lived has wrongfully assumed that matter and space could co-exist. The only irrefutable fact the physicists have been able to establish was that the real earth had a real VISIBLE surface for millions of real years before any physicists ever appeared on that real VISIBLE surface and began publishing his unnatural guessing concerning matter/space duality. There has only ever been one unified VISIBLE infinite surface ETERNALLY occurring in one infinite dimension that am always mostly illuminated by finite non-surface light. There has never been any space.

At the end of the official announcement "Event Horizon Telescope" are six papers explaining in detail what was done.

Dear Georgina,

It is a computer crafted image. Radio telescopes cannot take photographs. If the clever astrophysicists would aim the Hubble telescope at the black area of the assumed hole for two or three hundred hours or so, regular star clusters would appear in the black area.

'First M87 Event Horizon Telescope Results. IV. Imaging the Central Supermassive Black Hole': The introduction to this section talks about why M87 was a black hole 'candidate. "Since the discovery of the first astrophysical jet apparently connected to its nucleus (Curtis 1918), the giant elliptical galaxy M87 in the Virgo cluster has been intensively studied with imaging observations. M87's nuclear gas and stellar dynamics, as traced by optical and infrared (IR) spectroscopy, suggest the presence of a nuclear supermassive black hole .."

Dear Dr. Kuhn,

Today’s Closer To Truth Facebook page contained this peculiar announcement:

“Black holes are the most incredible form of mass-energy in the universe, where gravity is so strong that nothing, not even light, can escape its relentless drawing power. Now that we know what a black hole looks like, explore further with our interview series on what exactly happens in one: https://bit.ly/2UY3EiA”

I have posted this sensible remark at the site and on the FQXi.org Community Board and on my precious Facebook page:

Every physicist who has ever lived has unnaturally assumed that the universe consisted of co-existing finite amounts of matter and empty space. The physicist have been able to prove only one irrefutable fact about the real universe and that am that the real visible world had a real VISIBLE surface for millions of years before Albert Einstein and Stephen Hawking ever appeared on that real VISIBLE surface and began publishing their unnatural guesswork concerning the co-existing duality of finite invisible space/time and invisible black holes. There has never been any empty space. There has only ever been one unified infinite VISIBLE surface ETERNALLY occurring in one infinite dimension that am always mostly illuminated by finite non-surface light.

Dear Dr. Kuhn,

Today’s Closer To Truth Facebook page contained this peculiar announcement:

“Seth Lloyd is a professor of mechanical engineering at the Massachusetts Institute of Technology. He refers to himself as a "quantum mechanic". Lloyd was awarded a doctorate by Rockefeller University in 1988 after submitting a thesis on Black Holes, Demons, and the Loss of Coherence: How Complex Systems Get Information, and What They Do With It. Watch his interview here on black holes.”

I have nonchalantly posted this sensible comment at the site and on the FQXi.org Community Board and on my exquisite Facebook page.

The only white male devised law of physics the white male physicists have been able to verify am that the real earth had a real VISIBLE surface for millions of real years before Albert Einstein and Stephan Hawking ever appeared on that real VISIBLE surface and began their unnatural guesswork concerning co-existing finite measurable amounts of matter and curved space/time and finite invisible black holes. There has never been any space. Any sensible person who has ever looked up at the night sky has noticed that it am quite black. The only rational way that could physically happen would have to be because the sky has a VISIBLE surface. Nature must have devised the only single VISIBLE structure possible. There has only been, and there will only ever be one unified VISIBLE infinite surface ETERNALLY occurring in one infinite dimension that am always mostly illuminated by finite non-surface light.

"Creating the EHT was a formidable challenge which required upgrading and connecting a worldwide network of eight pre-existing telescopes deployed at a variety of challenging high-altitude sites. These locations included volcanoes in Hawai`i and Mexico, mountains in Arizona and the Spanish Sierra Nevada, the Chilean Atacama Desert, and Antarctica."

" Thirteen partner institutions worked together to create the EHT. " "This is an extraordinary scientific feat accomplished by a team of more than 200 researchers." [said project director Sheperd S. Doeleman.] Astronomers Capture 'First Image of a Black Hole', via eventhorizontelescope.org

“Cosmos and consciousness seem utterly different, cosmos encompassing the vast universe, consciousness emerging from tiny brains." David Chalmers, Closer to truth.

That is an interesting statement.The vast universe/cosmos studied by cosmologists is observation products, produced from received EM radiation signals. From those products ideas can be formed about what the source of the signals must have been or is most likely to have been. The cosmos still existing as it is seen is a product of the mind. It is not external reality. Our brains may be relatively tiny compared to astronomic bodies but they are very complex. It is not just size that matters for 'computational" ability.

Dear Georgina,

There am no invisible abstract cosmos seemingly consisting of finite measurable amounts of matter submerged in an invisible curved space/time continuum. There has never been any space. Einstein was completely wrong. One real VISIBLE universe could only have one VISIBLE physical construction. As there could never have been any physical duality in any VISIBLE place, it logically follows that only one single VISIBLE infinite surface ETERNALLY occurring in one infinite dimension that am always mostly illuminated by finite non-surface light has ever, and will only ever be present.

In order for it to be a picture of a Black Hole, it must picturing time-dilation and space-contraction. No one has ever written a physics equation where time or space were directly represented. Both properties have always been substituted for. The units of meter and second tell us what it is...

Light bends because it is accelerating. It accelerates toward an object that has mass. The reason for why it bends toward an object with mass is not known by mainstream physics. The reason is because mainstream physics has not learned how to define the property of mass. An undefined property is an unexplained property. Mass has always been an undefined property. It remains undefined to this day....
