I agree of course (your answer is the good one).What it is made of is still unknown.
Baryonic dark matter is object like dwarf stars and other tiny "dark"(=shineless -but i don't know if that word exist) objects.All that can be said is that most of it is NOT baryonic (ordinary) matter.
No idea ! Sorry :(can string theory explain this?
Dark matter is a type of matter that makes up about 27% of the universe, but cannot be seen or detected by telescopes. It is believed to have mass and gravitational pull, but does not emit or absorb light like regular matter.
Scientists use various methods to study dark matter, such as observing the effects of its gravitational pull on visible matter, analyzing the rotation of galaxies, and studying the cosmic microwave background radiation. They also conduct experiments using particle accelerators to try and create dark matter particles.
Dark matter is important because it helps explain the structure and evolution of the universe. Without the presence of dark matter, galaxies would not have enough mass to hold together and the universe would look very different. It also plays a role in the formation of large-scale structures like galaxy clusters.
There are several theories about dark matter, including the "cold dark matter" theory which suggests that dark matter is made up of slow-moving particles, and the "warm dark matter" theory which proposes that dark matter is composed of faster-moving particles. Other theories suggest that dark matter is not made up of particles at all, but rather a modification of the laws of gravity.
Scientists are constantly conducting experiments and using advanced technology to try and detect and study dark matter. They are also developing new theories and models to better understand the properties of dark matter and its role in the universe. Collaborative efforts between scientists from different fields, such as astrophysics and particle physics, are also being made to further our understanding of dark matter.
