Missing ordinary matter .....found maybe

#1  Postby Macdoc » May 30, 2020 12:13 am

At long last, all of the universe’s ordinary matter seems to be present and accounted for.

Astronomers have taken a new census of matter in the universe by examining how bright flashes of radio waves from other galaxies, called fast radio bursts, are distorted by particles on their way to Earth. This analysis shows that about half of the universe’s ordinary matter, which has eluded detection for decades, is lurking in intergalactic space, researchers report online May 27 in Nature.

Thanks for sharing Macdoc, this is really big news.

Oh good as that was my impression as well. What I don't understand tho is supposedly it was the "missing matter" that was affecting the gravitational anomaly of the galaxies ....spin etc.

If it's intergalactic ....then ?????

I feel that since we have detected gravitational waves it seems that gravity has strange effect at extreme distance. Also since even a single atom seems to have a gravitational factor it may be that he halos of “dark matter” surrounding galaxies is, after all, just matter we haven’t figured out how to detect.

Gravity got a long tail, much of the missing matter under the deep of deep space....platter bigger than the record.

Follow up by Ethan Siegel @ Forbes Science:
Sorry, Astronomers: Practically All Of The Universe's Matter Is Still Missing
...
In addition to that, there's also evidence for matter — normal matter, made of protons, neutrons and electrons — existing in the space between galaxies and galaxy clusters: the warm-hot intergalactic medium. This ionized plasma has been very difficult to detect, but has long been thought to exist in large quantities, making up significantly more mass than all the stars in the Universe combined.

Recently, to the highest precision ever, this sought-after matter has been detected as pulses of light known as fast radio bursts travel through them on their way to Earth. This is the "missing matter" that's finally been discovered, as reported in numerous outlets over the past week or two. It's an extremely important discovery for astrophysics, but it doesn't come close to solving the problem of what or where the actual "missing mass" in the Universe actually is.

Does this experiment have potential to eventually provide empirical evidence for the existence of dark matter? The article is full of cautions, but still... I am curious.
