the title pretty much says it all. i am just wondering if dark matter (which doesn't interact with light i believe) gets eaten by black holes, or is unaffected by them.
thechosenone said:hold up, what do you mean by dark energy acts like negative gravity? like dark energy is repelled by large masses?
Chronos said:I view it highly likely that galactic core SMB's originated almost entirely from dark matter.
It would be wrong, for example, if DE is nothing more than the cosmological constant ([itex]\omega[/itex] = -1).Wallace said:According to current understanding the ratio of dark to ordinary matter is the same for the entire history of the universe, back until the very first moments where we really don't have a clue anyway. Of course we really have no clue what DM is anyway so that could be wrong.
Point taken! The general thread was discussing DM and DE, and as you said, I got confused as to which one we were talking about here.Wallace said:You're confusing your darks Garth! We were discussing dark vs baryonic matter not dark energy. Dark and baryonic matter densities both drop with the inverse of the volume of the universe, hence their ratio's remain the same.
Black holes do not interact with dark matter in any significant way. Dark matter is believed to be a type of matter that does not interact with light or any other type of electromagnetic radiation. Black holes, on the other hand, interact with matter and light through gravity, but not with dark matter.
No, dark matter is not expected to be found inside a black hole. Dark matter is thought to be spread throughout the universe, while black holes are formed from the collapse of massive stars and are located in specific regions of space. The extreme gravitational pull of a black hole would also make it unlikely for dark matter to accumulate inside it.
No, black holes do not emit dark matter. Dark matter does not interact with light, so it cannot be emitted in the form of radiation. Black holes do emit radiation through processes such as Hawking radiation, but this radiation does not consist of dark matter particles.
Dark energy, which is believed to be responsible for the accelerated expansion of the universe, does not have a direct effect on black holes. Black holes are formed from the collapse of matter and are not subject to the same forces as objects on a cosmic scale. However, the presence of dark energy does affect the overall structure and evolution of the universe, which can indirectly impact the formation and behavior of black holes.
No, dark matter alone cannot cause a black hole to form. Black holes are formed from the collapse of massive stars, which is a result of the force of gravity. Dark matter does not interact with gravity in the same way as regular matter, so it cannot directly lead to the formation of a black hole. However, the gravitational pull of dark matter can contribute to the formation of large structures in the universe, such as galaxies, which can in turn lead to the formation of black holes.
