Can anyone tell me about Dark Matter I here its partly connected with Black holes
Can anyone tell me about Dark Matter
its a matter that is posulated to not reflex electromagnetic radiation, not just light but radio to gamma rays;
it is just made up the plasma theory kills it. it was the thorey used to explain galaxy rotation, then blackholes, now plasma; i like the plasma theory better.

well thats what i know
i wonder what dark matter feels like....hmm.... anyone know?
Apparantly it's damnnable heavy.
It's acutally packing material from boxes.

| In cosmology, dark matter refers to hypothetical matter particles, of unknown composition, that do not emit or reflect enough electromagnetic radiation to be detected directly, but whose presence can be inferred from gravitational effects on visible matter such as stars and galaxies. The dark matter hypothesis aims to explain several anomalous astronomical observations, such as anomalies in the rotational speed of galaxies (the galaxy rotation problem). |

You stole my line!!It comes from the poop of that super cute little creature that eats everything in sight from futurama
hey, i've done A-level physics, and now at uni, thought i might be able to help. Dark matter is matter that does not emit enough light or other radiation to be observed directly. Most of the matter in the universe is believed to be of this type. Cold dark matter has a low velocity compared to the speed of light during the epoch of recombination. An example would be elementary particles with mass about equal to that of a proton or higher. Hot dark matter had a high velocity (near the speed of light) during the epoch of recombination. An example would be light elementary particles.
If u understand that.. then well done (its from one of my assignments on Space etc)
Peace

There is no way the stuff can exist!
The effect that was though to be gravity, is the natural plasma line changing and moving. put some sand in bag of water and send it into space, watch what happends, after you shock it.

You say it cant exist?? I ask you Why cant it exist? So what if you cant actually see dark matter buddy, you cant see viruses either yet you know they exist.
Here are some of the technical results that I found:
1. Matter that is in space but is not visible to us because it emits no radiation by which to observe it. The motion of stars around the centers of their galaxies implies that about 90% of the matter in a typical galaxy is dark. Physicists speculate that there is also dark matter between the galaxies but this is harder to verify.
2.Matter that does not emit enough light or other radiation to be observed directly. Most of the matter in the universe is believed to be of this type. Cold dark matter had a low velocity compared to the speed of light during the epoch of recombination. An example would be elementary particles with mass about equal to that of a proton or higher. Hot dark matter had a high velocity (near the speed of light) during the epoch of recombination. An example would be light elementary particles.
3. Unseen matter that may make up more than 30 % of the Universe. As the name implies, dark matter does not interact with light or other electromagnetic radiation, so it cannot be seen directly, but it can be detected by measuring its gravitational effects. It is believed that dark matter was instrumental in forming galaxies early in the Big Bang.
4.In cosmology, dark matter consists of matter particles that cannot be detected by their emitted radiation but whose presence can be inferred from gravitational effects on visible matter such as stars and galaxies. Estimates of the amount of matter in the galaxies, based on gravitational effects, consistently suggest that there is far more matter than is directly observable. ...

perhaps you could read up on this book called "His Dark Materials" it has three volumes and it is written by philip pullman. it is basically answering your topic as the story is like a story but you could gather infomation about dark matter there. it is mostly gamma rays and at one point of the earth, we could see these gamma rays and it would show us the many other worlds in earth. i dunnoe if this book could help you understand it better but it would at least give you an idea of dark matter
