La búsqueda de materia oscura

The video explores the search for dark matter in the deepest mine in Europe, located in North Yorkshire. Scientists believe dark matter makes up 85% of the universe's mass, yet it remains undetected. The video explains the challenges of detecting these invisible particles, which rarely interact with other matter. To increase detection chances, scientists use mines to reduce cosmic ray interference. A liquid xenon detector is used to identify dark matter through scintillation. The discovery of dark matter would be a monumental breakthrough in physics and cosmology.

What is the primary goal of the scientists working in the deepest mine in Europe?

• To study ancient fossils

• To find new sources of energy

• To detect dark matter

• To extract valuable minerals

Why do scientists believe dark matter exists?

• Because it is visible through telescopes

• Due to the unexpected speed of galaxies

• Because it is a known element on Earth

• Due to its interaction with light

What makes dark matter difficult to detect?

• It moves too quickly

• It is too small to be seen

• It rarely interacts with other matter

• It is hidden behind stars

What is the purpose of using a liquid xenon detector in the search for dark matter?

• To measure the temperature of the mine

• To capture sound waves from the universe

• To analyze the chemical composition of rocks

• To detect flashes of light from dark matter particles

Why is finding dark matter considered a significant discovery in physics and cosmology?

• It will lead to the discovery of new planets

• It will change the laws of gravity

• It will solve the mystery of what holds galaxies together

• It will confirm the existence of new galaxies
