Dark matter trivia quiz
What is dark matter?
Answer: Dark matter is a hypothetical form of matter that is believed to
make up approximately 85% of the matter in the universe.
Who first proposed the existence of dark matter?
Answer: Swiss astronomer Fritz Zwicky proposed the existence of dark matter
in the 1930s.
How do scientists detect dark matter?
Answer: Scientists detect dark matter indirectly by observing its
gravitational effects on visible matter.
What is the difference between dark matter and dark
energy?
Answer: Dark matter is matter that does not interact with light, while dark
energy is an unknown force that is causing the expansion of the universe to
accelerate.
How do scientists measure the distribution of dark
matter in the universe?
Answer: Scientists use gravitational lensing to measure the distribution of
dark matter in the universe.
What is WIMP?
Answer: WIMP stands for Weakly Interacting Massive Particle, which is a
proposed type of dark matter particle.
What is MACHO?
Answer: MACHO stands for Massive Compact Halo Object, which is a type of
dark matter made up of objects such as black holes, neutron stars, or brown
dwarfs.
How much dark matter is believed to exist in the Milky
Way galaxy?
Answer: It is believed that approximately 90% of the matter in the Milky Way
galaxy is dark matter.
What is the bullet cluster?
Answer: The bullet cluster is a pair of colliding galaxy clusters that
provides strong evidence for the existence of dark matter.
What is the leading theory about the nature of dark
matter?
Answer: The leading theory is that dark matter is composed of Weakly
Interacting Massive Particles (WIMPs).
What is the difference between dark matter and
antimatter?
Answer: Dark matter is matter that does not interact with light, while
antimatter is matter that is made up of antiparticles.
How do scientists study the behavior of dark matter
particles?
Answer: Scientists use particle accelerators and other experimental
techniques to study the behavior of dark matter particles.
What is the dark matter halo?
Answer: The dark matter halo is a hypothetical structure that surrounds
galaxies and is composed of dark matter.
What is the dark matter problem?
Answer: The dark matter problem is the discrepancy between the observed
distribution of matter in the universe and the amount of matter that is
predicted by current theories.
What is the difference between dark matter and ordinary
matter?
Answer: Dark matter does not interact with light, while ordinary matter
does.
What is the difference between dark matter and dark
energy?
Answer: Dark matter is matter that is believed to make up the majority of
the matter in the universe, while dark energy is an unknown force that is
causing the expansion of the universe to accelerate.
What is the dark matter particle?
Answer: The dark matter particle is a hypothetical particle that is believed
to make up dark matter.
How did the discovery of the cosmic microwave
background radiation help to support the existence of dark matter?
Answer: The discovery of the cosmic microwave background radiation helped to
support the existence of dark matter by providing evidence for the Big Bang
theory, which predicts the amount of matter in the universe.
What is the difference between dark matter and black
holes?
Answer: Dark matter is a hypothetical form of matter that is believed to
make up approximately 85% of the matter in the universe, while black holes
are objects formed from the collapse of massive stars.
What is the difference between dark matter and
neutrinos?
Answer: Dark matter is a hypothetical form of matter that does not interact
with light, while neutrinos are subatomic particles that have mass and
interact weakly with other matter.
