Popular Post Waspie_Dwarf Posted October 10, 2017 Popular Post #1 Share Posted October 10, 2017 (edited) Half the universe’s missing matter has just been finally found Quote The missing links between galaxies have finally been found. This is the first detection of the roughly half of the normal matter in our universe – protons, neutrons and electrons – unaccounted for by previous observations of stars, galaxies and other bright objects in space. You have probably heard about the hunt for dark matter, a mysterious substance thought to permeate the universe, the effects of which we can see through its gravitational pull. But our models of the universe also say there should be about twice as much ordinary matter out there, compared with what we have observed so far.

Blaid Drwg Posted October 10, 2017 #2 Share Posted October 10, 2017 (edited) Somehow I got trouble to believe this to be true. I mean in this subject there are tests being done to determine what this dark matter realy is. So far I know this test was being done with axions wich would be according to them a very good candidate to be the dark matter. If these baryons would be the dark matter would this not have been determined already or are baryons something they recently discovered?

Except this article has absolutely nothing to do with dark matter. 20 minutes ago, Blaid Drwg said: If these baryons would be the dark matter would this not have been determined already or are baryons something they recently discovered? Baryons are ordinary matter. That is the entire point. 1 Link to comment Share on other sites More sharing options...

The pie below is what the universe would be made off according to NASA. These baryons are atoms or does it belong in to the dark energy? Link to comment Share on other sites More sharing options...

From the article: Quote This is the first detection of the roughly half of the normal matter in our universe – protons, neutrons and electrons and: Quote Two separate teams found the missing matter – made of particles called baryons rather than dark matter In other words baryons are the particles which make up atoms. 3 Link to comment Share on other sites More sharing options...
paperdyer Posted October 12, 2017 #6 Share Posted October 12, 2017 So the galaxies are tethered together with these baryons. I guess they have to strength or grow in some manner as the universe is still expanding. Hopefully they won't act like a bungee cord and snap back after they are fully stretched? If they do/did, maybe the cause of the "Big Bang"? 1 Link to comment Share on other sites More sharing options...

If they do/did, maybe the cause of the "Big Bang"? This word "baryon" seems to be causing a lot of confusion. Baryons are simply a series of subatomic particles, including the protons, neutrons and electrons which form ordinary atoms. They are simply the same stuff that makes up you, me the sun, planet earth and all the rest of ordinary matter in the universe. Indeed the article actually tells you what form these baryons take: Quote Two separate teams found the missing matter – made of particles called baryons rather than dark matter – linking galaxies together through filaments of hot, diffuse gas. (my emphasis) In fact the article refers to these baryons as being gas a further SIX times. So they do not need to have magical powers growing powers, it's just gas.

Parsec Posted October 12, 2017 #9 Share Posted October 12, 2017 Super cool (or hot in this case?)! So, did they possibly detect Whim instead of dark matter? 1 Link to comment Share on other sites More sharing options...
+DieChecker Posted October 13, 2017 #10 Share Posted October 13, 2017 I wonder how the filaments got there? Left from when the galaxies condensed? Intergalactic contrails? 1 Link to comment Share on other sites More sharing options...
mysticwerewolf Posted October 13, 2017 #11 Share Posted October 13, 2017 it is my unproven/unprovable opinion that the big bang from this cycle of existence was so powerful that much of the materal that resulted was blown into dust that is so small it cannot be seen.... but isn't radiation a molecular material? and if it is, is that considered a part of the visable universe yet to be found, or already found? 1 Link to comment Share on other sites More sharing options...

Electromagnetic radiation (light) and Particle Radiation (Alpha, Beta, etc.) are composed of subatomic particles. But I suspect you meant "matter," not "molecular material." In that case, yes, radiation is matter. Link to comment Share on other sites More sharing options...
