Can dark matter form "atoms" in the classical sense, such as dark hydrogen or dark helium?
I'm curious about dark matter. Can dark matter form "atoms" in the classical sense, such as dark hydrogen or dark helium?
Yes, it's possible. Dark matter refers to particles that do not interact with light or other forms of electromagnetic radiation, which makes it difficult to detect. However, some physicists have proposed that dark matter could form "atoms" if it interacts with itself via a new force. These "atoms" are often referred to as dark atoms or dark ions. They could potentially be made up of dark matter particles such as WIMPs (weakly interacting massive particles).
