For this reason, most experts think that dark matter is abundant in the universe and has had a strong influence on its structure and evolution. The primary evidence for dark matter comes from calculations showing that many galaxies would behave quite differently if they did not contain a large amount of unseen matter.

Does dark matter take up most of the universe?
It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest — everything on Earth, everything ever observed with all of our instruments, all normal matter — adds up to less than 5% of the universe.
What role does dark matter play in the universe?
Dark matter is the most mysterious, non-interacting substance in the Universe. Its gravitational effects are necessary to explain the rotation of galaxies, the motions of clusters, and the largest scale-structure in the entire Universe.
Is dark matter older than the universe?
Researchers believe dark matter makes up about 80% of the universe's mass, but its origins and composition remain among the most elusive mysteries in modern physics. A new Johns Hopkins University study suggests dark matter may have existed before the big bang.
Can dark matter give you superpowers?
User can to create or wield weaponry with power over dark matter, which grants the user a wide variety of dark matter-based abilities, including generation, transmutation, and creation of constructs, along with volatile abilities involving normal universal matter or antimatter.
Can you touch dark matter?
In theory, macros could directly interact with physical objects such as human bodies, causing "significant damage," according to the new study titled "Death by Dark Matter." Damage from such a collision would be comparable to a gunshot wound, the researchers wrote.
Are black holes dark matter?
Dark matter, which has never been directly observed, is thought to be most of the matter in the universe and act as the scaffolding upon which galaxies form and develop. On the other hand, black holes, which can be found at the centers of most galaxies, have been observed.
What is the lensing effect?
A gravitational lens can occur when a huge amount of matter, like a cluster of galaxies, creates a gravitational field that distorts and magnifies the light from distant galaxies that are behind it but in the same line of sight. The effect is like looking through a giant magnifying glass.
Is dark matter eternal?
Dark matter may not have always existed, but may have been created later on: before stars formed and before the CMB was emitted, but after the early stages of the hot Big Bang. The structure of the CMB peaks change dependent on what's in the Universe, as do the peaks and… [+]
What happens if you are exposed to dark matter?
If all of your ordinary matter atoms switched to dark matter atoms, your physical body would disintegrate. Without ordinary matter, there would be nothing to glue your atoms together anymore.
