Question 1

True or false: Dark matter can pass through your body without you ever feeling it.

Accepted Answer

True. Dark matter barely interacts with normal matter, so billions of particles likely pass through you every second unnoticed.

Question 2

True or false: Without dark matter, galaxies would fly apart because they spin too fast.

Accepted Answer

True. Galaxies rotate at speeds that would tear them apart without the extra gravitational pull from dark matter holding them together.

Question 3

True or false: Dark matter is completely invisible because it doesn't interact with light at all.

Accepted Answer

True. Dark matter doesn't emit, absorb, or reflect electromagnetic radiation, making it impossible to see with any telescope.

Question 4

True or false: Dark matter was first proposed to explain why the Moon stays in orbit around Earth.

Accepted Answer

False. Dark matter was first hypothesized in the 1930s by Fritz Zwicky to explain galaxy cluster motions, not lunar orbits.

Question 5

True or false: Dark matter particles have been directly detected in laboratory experiments on Earth.

Accepted Answer

False. Despite many attempts, no experiment has conclusively detected dark matter particles; its existence is inferred from gravitational effects.

Question 6

True or false: Dark matter makes up about 85% of all matter in the universe.

Accepted Answer

True. Dark matter accounts for roughly 85% of the universe's total mass, far outweighing ordinary matter.

Question 7

True or false: Dark matter only exists in the outer halos of galaxies, not near their centers.

Accepted Answer

False. Dark matter is distributed throughout galaxies, including near centers, though it dominates in the outer halo regions.

Question 8

True or false: Dark matter is made of tiny black holes left over from the Big Bang.

Accepted Answer

False. Primordial black holes are a hypothetical candidate, but there's no evidence they make up most dark matter; other particles are favored.
