Question

do dark matter exist??

Answer 1

Yes dark matter exists.
***Dark matter is the elusive, invisible substance that appears to make up more than 80% of the total mass in the universe far more than accounted for by 'regular' matter that makes up things like stars, planets and everything astronomers can directly observe.

Answer 2

Explanation:

• Because dark matter has not yet been observed directly, if it exists, it must barely interact with ordinary baryonic matter and radiation, except through gravity. Most dark matter is thought to be non-baryonic in nature; it may be composed of some as-yet undiscovered subatomic particles.
