Exploring Antimatter and Dark Matter on the ISS

What is the significance of finding antimatter in real life, as opposed to its portrayal in science fiction?

• It could lead to a Nobel Prize.

• It suggests time travel is possible.

• It is a sign of alien life.

• It indicates an impending explosion.

What is the primary function of the Alpha Magnetic Spectrometer (AMS) on the ISS?

• To detect gravitational waves.

• To analyze cosmic ray events.

• To study the Earth's atmosphere.

• To monitor solar flares.

What is one of the surprising findings of the AMS regarding cosmic rays?

• They include a significant fraction of positrons.

• They contain a high percentage of helium.

• They travel slower than the speed of light.

• They are mostly composed of dark matter.

What are the two potential sources of positrons detected by the AMS?

• Dark matter and pulsars.

• Galaxies and nebulae.

• Black holes and quasars.

• Supernovae and comets.

What is the main challenge in determining the source of positrons detected by the AMS?

• Lack of funding for the project.

• Inability to detect low-energy particles.

• Need for more data at higher energies.

• Interference from Earth's magnetic field.
