What is the primary limitation of the Large Hadron Collider in discovering new particles?

• It cannot reach the required energy levels.

• It is located in the wrong geographical area.

• It is too small to detect large particles.

• It is outdated and needs replacement.

What problem does supersymmetry aim to address in the standard model?

• The lack of a unified theory.

• The absence of a Higgs boson.

• The hierarchy problem related to gravity.

• The inability to detect dark matter.

How does the universe act as a natural particle accelerator?

• Through the collision of galaxies.

• Via supernova explosions and gamma ray bursts.

• By the gravitational pull of planets.

• Through the expansion of the universe.

What is the significance of the electroweak energy in supersymmetry?

• It is the energy level where the Higgs boson was discovered.

• It is the energy level where electromagnetic and weak forces merge.

• It is the energy level where gravity becomes dominant.

• It is the energy level required to detect dark matter.

What is the role of ANITA in cosmic ray experiments?
