Dark matter can be detected by its gravitational effect on nearby stars, causing them to very slightly alter their relative motions.

Dark matter is detected because it?
Dark matter can be detected because it got gravity.
Why do astronomers theorize that most of matter in galaxies and clusters is dark matter?
Dark matter may be invisible to light, but it can still be detected, through its gravitational interactions. Specifically, it can be detected: * By the fact that galaxies rotate way too fast, for the amount of known matter. * By gravitational lensing.
What do dark matter and dark energy in common?
They're both theoretical constructs and neither has actually been detected, measured, nor "seen".
What is a dark matter microscope used for?
There's no such thing as a "dark matter microscope." The whole point of dark matter is that it doesn't interact with electromagnetic radiation... if it did, it wouldn't be dark matter.
What can be detected from matter that has crossed an event horizon?
nothing
Dark matter is detected because it?
Dark matter can be detected because it got gravity.
Can Astronomer's directly detect dark energy and dark matter?
Dark matter and dark energy have NOT been detected yet, so any ideas about detecting dark energy and dark matter, whether it be directly or indirectly, is speculation for now.

Is dark or anti-matter been found or saved with the use of the collider?
"Anti-matter" . . . yes, routinely. "Dark matter" . . . no way to know. The reason it's called "dark" is that it can't be seen or detected in any way currently available to us; its existence is a hypothesis that's presently untestable.
What do astronomers speculate makes up at least 90 percent of matter in the universe?
Cold dark matter. It can't be seen or detected by its radiation. Some say that ranks it with Bigfoot and the Tooth Fairy!
What is an axion?
The axion is an hypothetical particle, which has never been detected. It was born as an elegant solution to the problem of CP in strong interactions and is one of the candidates for dark matter.

What are some possible forms the dark matter in the halo of the Milky Way might be in?
We don't yet know enough about dark matter - or even if it really exists - to be able to speculate on what "form", if any, it might take. You have to remember that "dark matter" is entirely theoretical, based on the supposed fact that the Milky Way doesn't have enough mass to keep it together, and that therefore there must be additional matter that we can't see - "dark" matter - to keep it all together. We've never detected any, nor do we know if we CAN detect any.
How do we know dark matter must exist if we can't sense it?
Actually, we CAN sense dark matter - we just can't see it, since it doesn't interact with light or other electromagnetic waves. Dark matter shows its presence through its gravitational attraction. For example: our galaxy, the Milky Way, rotates way too fast for the amount of known matter. So, to remain stable, there must be additional matter that can't be seen. Dark matter can also be detected through gravitational lensing - the amount of gravitational lensing depends on the amount of matter. Once again, the effect is greater than what can be attributed to known matter.
Where is the largest dark matter in the universe?
Dark matter is everywhere, there really is no place that has the most dark matter.
Is dark matter a subatomic particle?
Dark matter is an unknowm form of matter.
