If you suspect that something invisible may actually be dark matter,
then you should also be considering

In short: No, gravity is not dark matter. It's not matter of any kind. It's one of
the four fundamental forces in the universe. Gravitons, the hypothetical gauge
particles of gravity, might be dark matter except that one of the things we know
about them is that if they exist, they're massless.
What else can I help you with?
Dark matter is detected because it?
Dark matter can be detected because it got gravity.
What is the connection between gravity and dark matter?
When the total amount of mass in a galaxy is computed, and the total amount of gravity is calculated there is a discrepancy. There appears to be more matter in the galaxy than what can be observed. Dark matter was theorized as being matter that exists but does not interact with electromagnetic radiation. Because of this, it cannot be seen. That is why it is called dark matter.
How are stars dust and gas similar to dark matter?
The only similarity we know of is that they all seem to interact with gravity. Aside from that, scientists do not know what dark matter is.
If there is no dark matter in the Milky Way Galaxy what is the best alternative explanation for the observations?
If there is no dark matter in the Milky Way Galaxy, one alternative explanation for the observations could be modifications to the theory of gravity, such as MOND (Modified Newtonian Dynamics). MOND proposes that gravity behaves differently on large scales than predicted by Newtonian physics, potentially explaining the observed phenomena without the need for dark matter.
What is dark matter in the big bang theory?
Dark matter is matter that does not interact via the electromagnetic force. We don't really know what dark matter is, exactly; there are several possibilities. We know that it interacts via gravity, meaning it has mass. It may, or may not, or SOME of it may, interact via the weak force as well.
How do atronomers detect dark matter?
Gravity. We cannot see or directly detect "dark matter", and the only reason why astronomers talk about "dark matter" is that galaxies like the Milky Way appear to be spinning too fast for gravity to hold them together. Or at least, for the gravity of the mass that we can SEE to hold them together. Gravity comes from matter, and we can't see enough matter, so it must be "dark matter". This may be in the form of trillions of invisibly-dim brown dwarf stars, or in black holes from which no light ever escapes - or it may be something entirely new. "Dark matter" is the something new.
Is gravity dark matter?
Gravity is not matter (dark or light), it is a property of mass and space that results in forces. Matter and force are entirely different things.
Dark matter is detected because it?
Dark matter can be detected because it got gravity.
What is the connection between gravity and dark matter?
When the total amount of mass in a galaxy is computed, and the total amount of gravity is calculated there is a discrepancy. There appears to be more matter in the galaxy than what can be observed. Dark matter was theorized as being matter that exists but does not interact with electromagnetic radiation. Because of this, it cannot be seen. That is why it is called dark matter.
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 use of dark matter?
Dark matter is sort of a cosmic scaffolding, holding galaxies together through sheer abundance, and since it only interacts with matter gravitationally, you cannot see it, and nor can you detect it....yet.
Does anyone no if you have proof dark matter exists?
The clear answer is, we don't. We cannot detect the hypothetical "dark matter", and the only reason we are talking about "dark matter" is that we cannot actually see enough mass in the Milky Way galaxy to account for the gravity that we know must be there - because the Milky Way would fly apart with only the mass that we can see. The "dark matter" may be in the form of invisibly-dim brown dwarf stars, or black holes, or "something else". Dark matter is the "something else". Everything you read about dark matter is a guess.
How does a black hole gobble dark matter?
Not much is known about dark matter, but pressumably, it would react to gravity just like normal matter.
Where do you get the dark matter?
Dark matter is all around us, inside and out, is what holds the forces of gravity together, keeps it from flying apart.
If gravity and acceleration are the same how do we know dark matter isn't dark acceleration?
Gravity and acceleration are definitely NOT the same. Gravity and acceleration can have the same EFFECTS.Dark matter is some unknown substance, which provides gravitational attraction. As a result, just like any regular matter, it will accelerate any nearby matter. But calling it "dark acceleration" doesn't really solve the mystery of what it's made of.
Does dark matter get sucked into blackholes also?
Not much is known about dark matter. However, the answer is likely "yes", since dark matter does interact with gravitation.
How are star dust gas and dark matter related?
There is no consensus on what dark matter or dark energy is so we cannot tell at this time.
