Questions about dark matter

Hi Guest,

Dark matter and singularities are both hypothetical, so no one but God can answer your questions with surety. The more massive a black hole is, the more space it takes up. I see no reason to expect a singularity at the center of a black hole. Questions about black holes are answered here. I see no reason why dark matter could not form black holes since it has gravity. Since it is thought to be 70-80% of the mass of the universe, I would expect the majority of BHs to be dark or mostly dark.

"What would happen if a DM black hole collided with a barionic black hole of equal mass?"

Dark matter is not supposed to interact with ordinary matter by electromagnetic forces, and has no atoms, so I would expect a collision of the two to just increase the mass.

"Since it [dark matter] is thought to be 70-80% of the mass of the universe, I would expect the majority of BHs to be dark or mostly dark."

Black, even.

stating that dark matter can form ...something....like a black hole is analogue to the idea that a black hole is formed out of nothing, since dark matter is just a concept born because the facts don't fit the theory. just nonsense.

What about anti-matter? Can it form a black hole? Does it form a black hole or an anti-black hole or the opposite of a black hole.

The opposite of a black hole is a white pole. Whereas black holes are characterized by their intense gravity, white poles are characterized by their intense -- you guessed it -- levity.

<just kidding>

Black holes can spin, exhibit an electric charge and have a magnetic field. There is no reason an antimatter black hole could not exhibit these same properties, although I can't say with certainty if the polarity of the electric charge is always the same for all conventional black holes. If it is, I would suspect that charged antimatter black holes would probably exhibit the opposite polarity.

Without going in boring details I will try to explain in layman term

Dark matter is energy which converted from given mass. Best may to visualize this is from Einstein equation E=1/2 mC2 ( E= energy, m = mass and c is speed of light).

We can convert this energy back to mass and vise versa.

Two dark mas if having resonating frequency will be packed together like two mass with different atomic mass. if they are compatible.

Dark hole will interact with metal and is like same as heating water on stove in morning to make coffee.

Energy can be absorbed and desorbed. Dark hole can consume mass since it is at high energy level

I just knew the Standard Model wouldn't hold up to close scrutiny...

Perhaps dark matter is merely a dimple in the fabric of space time,formed immediately after the big bang.Perhaps space time is not perfectly flat without the presence of matter.If space"dimples" exist, they would be indistinguishable from "dark matter",bending light, and causing the primordial clouds of gas to form under their influence., which would eventually become galaxies.

Dark matter doesn't bend light, it's totally transparent.

Correction, the gravity of dark matter can bend light, but otherwise it doesn't interact with normal matter by electromagnetic forces. There may not be any dark matter. See here.

Here's a good link for ya:

Next time actually make it a link using the link icon in the editor.

So now they are trying to explain how a hypothetical object got big too fast. Interesting.
