Exploring Dark Matter

What is the primary challenge in understanding dark matter?

• It is only found in distant galaxies.

• It is too small to be seen.

• It does not interact with light.

• It is made of ordinary atoms.

Why do scientists believe dark matter is crucial for galaxy stability?

• It repels other galaxies.

• It provides additional gravity.

• It is denser than ordinary matter.

• It emits strong light.

What is the purpose of the sensitive cameras developed by Professor Mark Cropper's team?

• To photograph black holes.

• To capture images of distant stars.

• To measure the temperature of galaxies.

• To detect weak gravitational distortions.

What is an Einstein ring?

• A halo of dark matter.

• A type of black hole.

• A ring of stars around a galaxy.

• A warped image of a distant galaxy.

What is the main goal of the Euclid Space Telescope?

• To study the sun's activity.

• To hunt for Einstein rings.

• To find new planets.

• To map the surface of Mars.

What are WIMPs in the context of dark matter?

• Widely Interacting Massive Particles.

• Weakly Identified Magnetic Particles.

• Widely Identified Molecular Particles.

• Weakly Interacting Massive Particles.

What is the Xenon1T detector used for?

• To observe solar flares.

• To detect cosmic rays.

• To measure the speed of light.

• To capture dark matter interactions.

Why is the Xenon in the Xenon1T detector kept extremely pure?

• To make it more visible.

• To increase its weight.

• To avoid contamination from natural radiation.

• To prevent it from freezing.

What is the significance of detecting a dark matter particle?

• It would explain the expansion of the universe.

• It would provide direct evidence of dark matter.

• It would validate the theory of relativity.

• It would confirm the existence of black holes.

What is the main challenge in detecting dark matter particles?

• They are only found in other galaxies.

• They are too large to be detected.

• They interact very weakly with other matter.

• They emit too much light.
