The Mystery of Baryonic Matter

"Dark Matter" is a very interesting thing. Some of it can not be observed, but the matter that can be observed is called baryonic matter. Yet, astronomers have recently noticed that when they try to find them in nearby galaxies, they only find half of the baryonic matter they predict to find. Currently, Grad student Michael Anderson and Professor Bregman are trying to figure out where this matter has gone. One prediction is that it is in the "galactic halo", a hot, thin ring of gas. This is where Anderson and Prof. Bregman assume the matter has always been and that it "never fell into the galaxies in the first place". As of now, the missing baryonic is still a mystery.

Dark matter is very interesting. It's funny that it was only discovered recently and used an explanation for the extra matter in the universe, and now there's supposedly not as much as expected. It would be interesting if they discovered another form of matter (darker matter?) that was in place of the dark matter they thought they would find. Only time will tell if the dark matter and dark energy theories hold.

Hahaha, darker matter. It does seem as if that's a possibility. The "discovery" of a new type of matter in order to take the place of the matter that was already supposed to be there to explain further missing matter. My question is, where is this "galactic halo" located? Is this supposedly the original source of all dark matter. The article makes it sound as if the dark matter that's missing never "fell" into the corresponding galaxies, which makes me think that maybe all dark matter was originally found in this galactic halo.

O.o

Dark Matter is such a mystery to me. It is astonishing to me that scientists have come so far as studying something that is nearly impossible to detect. How can one say that baryonic matter really isn't or really is there if it is non-detectable? Coming from the "Age of Technology and Ideas", I have faith that our scientists will soon be discovering new ways to find better updated information about baryonic matter. For now, we will just look forward to hearing more from them, keeping up with the new discoveries, and making suggestions and theories of our own!
