Mainly that dark matter interacts with dark matter and with normal matter via the gravitational force; and that it DOES NOT interact with normal matter via any other known force. Or, if there is any interaction, it does so to such a small extent that it hasn't been possible to detect this so far.
Not much is known yet about the properties of dark matter, so it is really hard to compare this.
We don't really know very much about dark matter, so most of its properties (like how it feels) are not known.
Dark matter has yet to be discovered or its properties fully understood

A dark matter microscope is used to indirectly detect and study dark matter by analyzing the impact it has on the distribution of visible matter in space. By observing the gravitational effects of dark matter on visible matter, scientists can infer the presence and properties of dark matter particles.
Too little is known about dark matter to speculcate on this.
physical
Not much is known about dark matter. However, the answer is likely "yes", since dark matter does interact with gravitation.
Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
This is not known. All that is known about dark matter is that it has mass. Searches are underway to try to work out what it is. The existence of dark matter was learned rather recently, and its composition is still being speculated, hence the name. There are several theories about what dark matter may be made of.
