what is warm hole and dark matter
Answers
Answer:
According to a paper posted to the arXiv pre-print server last week, the difference between an everyday supermassive black hole and a space-time tunneling wormhole may be a lacing of dark matter. While it sounds like crank fodder of the sort that not infrequently winds up on arXiv, the idea may hold actual water.
The theory pertains to one particular proposed form of dark matter known as axionic dark matter. Axions, a hypothesized fundamental particle of matter relating to the strong nuclear force, aren't the only proposed candidate for dark matter, but as searches for WIMPs (weakly-interacting massive particles)—far and away the favored proposed particle comprising dark matter—come up empty, axionic dark matter has become a more and more plausible scenario. As theorized, dark matter axions would permeate the universe as an energetic condensate, interacting only very weakly via the electromagnetic force and existing as a kind of ghostly cosmic foam.
Answer:
- A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe.
- Dark matter is a hypothetical invisible mass thought to be responsible for adding gravity to galaxies and other bodies.
