How are dark energy and dark matter explained in braneworld cosmology?
Answers
✔✔The central idea is that the visible, three-dimensional universe is restricted to a braneinside a higher-dimensional space, called the "bulk" (also known as "hyperspace"). If the additional dimensions are compact, then the observed universe contains the extra dimension, and then no reference to the bulk is appropriate. In the bulk model,
✔✔ at least some of the extra dimensions are extensive (possibly infinite), and other branes may be moving through this bulk. Interactions with the bulk, and possibly with other branes, can influence our brane and thus introduce effects not seen in more standard cosmological models.
Revealing some mysteries of our Universe.
Hey!
Dark matter is a hypothetical particle predicted by scientists which results in attraction between stars in galaxies.
______________________________________
Universe has 26.8% (approx) dark matter.
Accompanied with dark energy, these particles are mysterious particles in the Universe till now.
Due to dark matter, stars are there in place of galaxies
We can't see such particles, so it named as dark matter.
Dark matter is also responsible for bending of light due to spacetime curvature.
These particles haven't antimatter.
Dark energy supposed to be hypothetical energy in opposition to gravity.
It leads to expansion of the Universe.
Galaxies are going apart due to this energy.
Universe has approx 69% of dark energy.
We also can't see this energy.
In braneworld cosmology, these particles are not made up of strings. Neither it can be explained by simple string theory (all five types xD)
