There they go again: claiming to have a map of something never observed.
This time it's an article in the Daily Mail with this headline: "See dark matter like NEVER before: NASA reveals one of the most detailed maps of the elusive substance yet – confirming its vital influence on the universe." We have these claims:
"NASA has revealed one of the most detailed maps of dark matter yet. Taken by the James Webb Space Telescope, the map suggests the elusive substance acts as a hidden framework on which entire galaxies are built...'By revealing dark matter with unprecedented precision, our map shows how an invisible component of the Universe has structured visible matter to the point of enabling the emergence of galaxies, stars, and ultimately life itself,' explained Dr Gavin Leroy, co–author of the study."
But how can someone have a map of dark matter locations when dark matter has never been observed? All attempts thus far to make direct observations of dark matter have failed. Dark matter doesn't even have a place in the Standard Model of Physics, and no evidence for it has turned up at the Large Hadron Collider.
We have in the Daily Mail article a claim that the map of dark matter was made by studying gravitational lensing. Gravitational lensing is what the article is referring to when the article states this: "Because dark matter is invisible, the team looked for it by observing how its mass curves space itself, which in turn bends the light travelling to Earth from distant galaxies."
But observations of gravitational lensing are not equivalent to observations of dark matter. Gravitational lensing is a strange effect produced on light rays bent by the gravity of high concentrations of matter. Such matter can be any type of matter: either normal matter or possibly some type of dark matter.
As Scientific American puts it when describing gravitational lensing:
"According to Albert Einstein’s general theory of relativity, mass warps space, so a large amount of matter in the foreground of a galaxy can bend its light in a way that makes it look slightly squashed. This is true whether the foreground mass is made of invisible dark matter or ordinary matter."
So if you are claiming to have a map of dark matter made by observing gravitational lensing, you are doing something rather like announcing that you have a map of UFO landing sites made by observing small burnt patches in the forest. Such patches might be produced by hot UFO's that are landing, but they also might be produced by ordinary lightning flashes, or by people setting campfires.
We have in the Daily Mail article some misleading language by a scientist, the language below:
"Dr Diana Scognamiglio, co–author of the study from NASA's Jet Propulsion Laboratory, said: 'This is the largest dark matter map we've made with Webb, and it's twice as sharp as any dark matter map made by other observatories.
'Previously, we were looking at a blurry picture of dark matter.
'Now we're seeing the invisible scaffolding of the Universe in stunning detail, thanks to Webb's incredible resolution'."
No, there was no actual "dark matter map" created. All that went on is that scientists saw things that can be explained by matter, and jumped to the conclusion that such things were made by dark matter, without any adequate warrant. You can't see things that are invisible.
The scientific paper of these claimants is entitled "An ultra-high-resolution map of (dark) matter." The title is inaccurate. The paper has figures, and none of them is labeled as a map of dark matter. The term "dark matter" is not even used in any of the captions of the paper's figures. We have here another case of what is so common these days in science literature: citation-hungry scientists giving their papers titles that do not match what is in the paper.
What scientists call "dark matter" is something they believe is not actually dark matter but instead invisible matter. A more candid term for "dark matter" would be "spooky matter." Scientists boasting about having created a dark matter map may say that they "saw dark matter." But they should instead merely be saying that they saw regular matter and energy, and that they inferred dark matter or guessed that dark matter was somewhere.
What type of "map of the spooky" would have much more empirical warrant than the claimed "map of spooky matter" that is a claimed dark matter map? It would be what we might call a paraverse interaction map
To explain such a map, I must explain the concept of the paraverse, explained in my 2016 post "The Possibility of a Paraverse." The term paraverse is formed from the end of the word “universe” and from the prefix “para,” which means “beside” or “to the side of.” We can define a paraverse as some hypothetical realm of existence that is in some sense connected to our universe in a way that allows information and causal influences to flow between our universe and this other realm of existence.
- The multiverse concept postulates many other universes, while the paraverse concept postulates only a single other realm of existence (without excluding the possibility of additional universes).
- The multiverse idea typically postulates universes that are completely isolated from each other, without communication or interaction between any two of the universes; but conversely the paraverse concept says there may indeed be interaction or communication between our universe and some other realm of existence, with perhaps causes and effects sometimes flowing between the two.
