Understanding Quantum Mechanics and Relativity

What was the significant scientific prediction made in 1928?

• The existence of black holes

• The discovery of the Higgs boson

• The unification of electricity and magnetism

• The existence of anti-matter

What is a major limitation of the Schrodinger equation?

• It cannot describe particles with mass

• It is incompatible with Einstein's relativity

• It does not account for gravitational forces

• It only applies to macroscopic objects

What principle did Wolfgang Pauli introduce to explain electron energy levels?

• Complementarity Principle

• Heisenberg Uncertainty Principle

What is the relationship between matter and anti-matter particles?

• They have different masses

• They have the same charge

• They cannot interact with each other

• They have opposite charges

What is a key feature of quantum fields?

• They are unaffected by electromagnetic fields

• They are limited to specific regions of space

• They have a definite energy, usually zero

• They only exist in the presence of matter

What does the concept of a multiverse suggest?

• There is only one universe
