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.
What else can I help you with?
Do scientist think that dark matter and dark energy exist?
Yes, they do.
What do you mean by dark matter?
Dark matter is matter that is inferred to exist from gravitational effects on visible matter and background radiation, but is undetectable by emitted or scattered electromagnetic radiation.
Dark matter is inferred to exist because?
Dark matter is inferred to exist because of the gravitational effects it has on visible matter in the universe. Observations of galaxies rotating faster than expected and the bending of light around massive objects support the presence of dark matter. However, dark matter itself has not been directly observed or detected.
Why dark energy and matter does not obey standard physics and chemistry?
Standard physics and chemistry are based on the energy and matter that we know. We do not know much about dark energy or dark matter, but only that it may exist.
What is matter in the universe?
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.
What have Astronomers have been unable to prove that what exist?
'Dark matter' and 'dark energy' have not been observed or proven yet.
Why do two dark matter particles collide?
Not much is known about dark matter. It is fairly certain that it does exist, but not much more is known. Thus, any ideas on what would happen when two dark matter particles meet seem very speculative.
Does the black hole and dark matter are same?
No. Black holes exist where gravity is so powerful that nothing can get out, not even light. "Dark Matter" is a vague hypothesis about the need for some additional mass that needs to exist in the galaxy in order to explain the way the galaxy does behave. We're not sure that "dark matter" exists at all.
What materials are believed to compose dark matter?
A serious hypothesis doesn't exist now.
How many people believe dark matter exists?
Dark Matter is required to exist because without it all galaxies would fly apart. In our Milky Way Galaxy Dark Matter accounts for 90% of the entire mass of the galaxy. Dark Matter is simply that, Dark. As it cannot be seen and has a very weak force. It only interacts with gravity.
What is the different forms that matter can exist?
States of matter are: - solid - liquid - gas - plasma - Bose-Einstein condensate - dark matter - fermionic condenste - strange matter etc.
Why does motion sensor can't detect in very dark area?
Because motion sensors sense the movement of light, so if its dark, it cant see.
