What Is Dark Matter?

[stromboli]

Well, forget superglue. sounds more like stucco.

I guess the dark matter clumps first, and then attracts the light matter. It's not really a chicken and egg thing. Or maybe it is: the egg came long before the chicken, as the DM came well before the LM.

When something happens in a regular fashion like in this case, the ratio of dark matter to baryonic matter is constant throughout the billions of galaxies, it is not an accident and is in need of an explanation.

They used to say that about lightning, gravity or why milk is white?

Has anyone consulted with Deepak Chopra on this?

Until they actually observe and capture some of this alleged "dark matter," I will regard it with the same skepticism that I do God. In fact, it's exactly like God: invisible, undetectable, can't see it or touch it or interact with it, yet people insist that it HAS to be out there somewhere because of all the things that happen that they don't understand. There are currently 118 elements in the Period Table. Which of them is supposed to comprise "dark matter?" Scientists should consider that they might be misinterpreting the data. At one time, we thought there were canals on Mars, and they turned out to be an illusion.

Dark Matter is postulated on the fact that galaxies - and there are billions of billions of billions of them. - all have missing masses to justify their structure. It's "Dark" because it doesn't interact with matter through the electromagnetic force, only gravitational force. So you won't find it on the Periodic table. This is how science works: there is a fact in need of explanation, that requires a theory. Comparing that to religion is quite an insult.

Well said.  I will add that, in my understanding, we can calculate a gravitational force that we know exists.  We just don't know what is causing it.  This "something" is hereby dubbed "dark matter".

Gravity according to Einstein is caused by a curve in space time. Rap your head around that! Or in Quantum mechanics, particles called gravitons that create a gravitational field. Where's Joseph when we need him? 

[PickelledEggs]

So basically dark matter is the same as asking if a bear shits in the woods and there's nobody there to see it does that tree next to the bear make a sound?

Not sure... But the shit makes a smell!

If the did, I'm sure he commented about the need for us to feel one-ness with it....

I'm here. GR and QM are not needed to postulate Dark Matter. Just Plain old Newtonian physics.
