The 4 Greatest Mysteries of Physics

Why do we remember the past but not the future according to physics?

• Because time is a one-way street

• Due to the nature of gravity

• Due to the laws of thermodynamics

• Because of the direction of entropy

What is a proposed solution to the question of why the universe started in a low entropy state?

• The universe is a low entropy bubble in a chaotic whole

• The universe is governed by dark matter

• The universe is expanding due to dark energy

• The universe is influenced by black holes

What is the main reason scientists believe in cosmic inflation?

• It explains the homogeneity of the universe

• It predicts the existence of dark matter

• It accounts for the speed of light

• It describes the formation of galaxies

What is the role of the inflaton in the theory of inflation?

• It is a theory that explains dark matter

• It is a force that opposes gravity

• It is a constant that defines the speed of light

• It is a hypothetical particle that drives inflation

What is the fine-tuning problem in physics?

• The specific mass of electrons

• The exact speed of light

• The unique properties of gravity

• The precise values of fundamental constants

What is one speculative idea about the fine-tuning problem?

• The existence of a multiverse

• The presence of dark energy

• The role of black holes

• The influence of cosmic rays

Which theory attempts to unify general relativity and quantum field theory?

• String theory

• Newtonian physics

• Electromagnetic theory

• Thermodynamics

What is the main challenge in finding a theory of everything?

• The complexity of the fine-tuning problem

• The absence of evidence for cosmic inflation

• The lack of understanding of dark matter

• The incompatibility of general relativity and quantum field theory

What is the significance of the Muon g-2 experiment in physics?

• It explains the mass of electrons

• It measures the speed of light

• It confirms the existence of dark energy

• It provides rare hints for a theory of everything

What does the interdisciplinary approach in physics emphasize?

• Ignoring unsolved problems

• Collaboration across different fields

• Focusing solely on particle physics

• Studying only cosmology
