Questions & Answers

Q: How big of a telescope is needed to observe stars in Andromeda?

Observers can see stars in Andromeda with a backyard telescope due to their distribution and the spacing between them.

Q: Is the universe larger than the observable universe?

Astronomers conclude that the actual universe must be larger due to evidence from cosmic radiation and measures of the universe's mass density and curvature.

Q: Are black holes solid objects?

The internal structure of black holes is unknown, with theories ranging from a solid object to point of infinite density.

Q: Could dark matter consist of black holes?

Primordial mass black holes are proposed as a dark matter form, but various other components like sterile neutrinos and axions are also considered.
