Why does all matter have gravitational force?
All matter has gravitational force because mass is a fundamental property of matter, and gravity is the force of attraction between objects with mass. The strength of the gravitational force between two objects is determined by their masses and the distance between them.
What are the three main sources of gravity in our galaxy?
The three main sources of gravity in our galaxy are stars, dark matter, and gas clouds. Stars contribute a significant portion of the mass within the galaxy and thus exert a strong gravitational pull. Dark matter, which is invisible and comprises a large portion of the galaxy's mass, also contributes to gravitational forces. Gas clouds, although less massive than stars and dark matter, still have significant gravitational effects within our galaxy.
How is gravitational lensing related to dark matter and what role does it play in understanding the distribution of dark matter in the universe?
Gravitational lensing occurs when the gravity of massive objects, like dark matter, bends and distorts light from distant sources. By studying these lensing effects, scientists can map the distribution of dark matter in the universe. This helps us understand the role of dark matter in shaping the large-scale structure of the cosmos.
What is causing the acceleration of the universe's expansion?
The acceleration of the universe's expansion is believed to be caused by a mysterious force called dark energy. This force is thought to counteract the gravitational pull of matter, causing the universe to expand at an increasing rate.
Do you have any thing like anti gravitational force in the universe?
There is a force called as gravitational force in the universe. The most beloved scientist, Newton has derived the law of gravity. But it has never been explained that as to why there is force of attraction and not the force of repulsion. When there is the force of attraction, there has to be the corresponding force of repulsion in the nature. You can not have the isolated north pole, with out the presence of south pole. So you have the force of attraction between matter to matter. You have force of attraction between anti-matter to anti-matter. So there has to be force of repulsion between matter to anti-matter. So the matter will repel the anti-matter in the space. So you have lost the universe (universes) in the space. The presence of matter is the proof that the anti-matter exists in the space in exactly equal amount. This is subjected to the inter conversion of matter into energy as per the law of Einstein, that is E = m c 2. The law of gravity is stated as F = G m 1* m 2 / r 2. If one of the mass is anti-matter, then the formula is : minus F = G (minus m 1)* m 2. Here the value of F also becomes negative. So that becomes the force anti to the force of gravity. That is force of repulsion. Hence proved.
What are the properties of dark matter?
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.

Why is it unlikely that dark matter is made up of stars?
Dark matter is by definition not visible nor reactive to the electromagnetic force; this would exclude visible matter, including stars. One might argue that the effects which dark matter has been used to explain could be consequential to gravitational pull from ordinary stars, perhaps owing to a gross miscalculation or an incomplete understanding of gravitational force -- but this would be a different position than to say dark matter itself is stellar material.
Is there enough dark matter to halt the the current cosmic expansion?
Not only is there not enough matter (dark or otherwise) to stop and reverse cosmic expansion, the rate of that expansion has been increasing over time. It would appear that dark energy is achieving "victory" over all matter.
Is dark matter the force?
Dark matter and The Force are not the same thing. The Force is a fictional power that connects all things. Dark matter is a real-world, theoretical matter that figures into physics and mathematics.
Does light or mass change into dark light or dark mass as it approaches a strong gravitational force such as a super massive black hole?
It is not believed to be, but there is still very little known about dark matter, so maybe,

Dark matter, which is invisible and comprises a large portion of the galaxy's mass, also contributes to gravitational forces. Gas clouds, although less massive than stars and dark matter, still have significant gravitational effects within our galaxy.
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.
Dark matter can be detected by its?
Dark matter can be detected by its gravitational effects on visible matter and light. It does not emit, absorb, or reflect light, making it invisible to telescopes. Scientists use indirect methods like gravitational lensing and measuring the rotational speeds of galaxies to study and detect the presence of dark matter.
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.
