Understanding Dark Matter and Galactic Structures

What role does dark matter play in the formation of galaxies?

• It offers gravity to pull matter together.

• It provides light to galaxies.

• It repels regular matter.

• It creates black holes.

What is the Great Wall in the context of galactic structures?

• A structure made of stars and planets.

• A wall of dark matter blocking light.

• A filament of galaxies stretching millions of light years.

• A barrier preventing galaxy formation.

How does ALMA help astronomers understand the universe?

• By detecting black holes.

• By measuring the temperature of stars.

• By observing the formation of early galactic structures.

• By creating new galaxies.

What do dark matter filaments do in the universe?

• They create stars.

• They destroy galaxies.

• They form a web that influences galaxy formation.

• They emit light.

How do dark matter filaments affect galaxy clusters?

• They make galaxy clusters invisible.

• They provide the building blocks for galaxy clusters.

• They slow down galaxy clusters.

• They repel galaxy clusters.

What analogy is used to explain the role of dark matter in the universe?

• Dark matter is like a forest.

• Dark matter is like a mountain.

• Dark matter is like a city grid.

• Dark matter is like a river.

How is New York City used as an analogy for dark matter's role?

• The roads are compared to dark matter.

• The buildings are compared to dark matter.

• The parks are compared to dark matter.

• The rivers are compared to dark matter.

Who was the first to detect unusual movement in galaxies suggesting dark matter?

• Isaac Newton

• Edwin Hubble

• Fritz Zwicky

• Albert Einstein

What was Fritz Zwicky's contribution to the understanding of dark matter?

• He discovered black holes.

• He proposed the existence of an unknown material adding mass.

• He mapped the Milky Way.

• He invented the telescope.

Why was Fritz Zwicky's idea of dark matter initially ignored?

• He only studied stars.

• He was ahead of his time and unlikable.

• He was not a scientist.

• He had no evidence.
