Understanding Dark Matter: WIMPs and Axions

What is the primary role of dark matter in the universe?

• To hold galaxies together

• To emit light and heat

• To form stars

• To create black holes

Why is the WIMP model considered incomplete?

• It is too simple

• It predicts too many large galaxies

• It has not been detected yet

• It explains all cosmic structures perfectly

What is a unique feature of axions compared to WIMPs?

• They are easily detectable

• They interact strongly with visible matter

• They have a longer de Broglie wavelength

• They are heavier than WIMPs

How do axionic dark matter waves behave differently from WIMP particles?

• They are stationary

• They emit radiation

• They create interference patterns

• They form solid structures

What is a potential advantage of axionic dark matter over WIMPs?

• It is easier to detect

• It explains smaller cosmic structures better

• It is more massive

• It interacts with electromagnetic forces

What is a Bose-Einstein condensate in the context of axionic dark matter?

• A state where particles emit light

• A state where particles are stationary

• A state where particles have high friction

• A state where particles flow with zero viscosity

Why might axionic dark matter be difficult to distinguish from WIMP dark matter?

• Both are easily detectable

• Both emit the same type of radiation

• Both have similar gravitational effects

• Both have the same mass

What is a reason to explore axions as a dark matter candidate?

• They are part of the standard model

• They provide a new explanation for cosmic structures

• They are already detected

• They are heavier than WIMPs

What is the concept of Fuzzy Dark Matter?

• Dark matter with a wave-like nature on large scales

• Dark matter that forms black holes

• Dark matter with a solid structure

• Dark matter that emits light

How might Fuzzy Dark Matter be detected?

• By its interaction with electromagnetic fields

• Through direct particle collisions

• By observing its gravitational lensing effects

• Through its thermal emissions
