BBT & String Theory

What is the Big Bang Theory?

• It's a theory about the creation of the universe

• It's a theory about the formation of galaxies

• It's a theory about the evolution of life on Earth

• It's a theory about the extinction of dinosaurs

Who proposed the Big Bang Theory?

• Albert Einstein

• Isaac Newton

• Georges Lemaître

• Galileo Galilei

What evidence supports the Big Bang Theory?

• The expansion of the universe

• The cosmic microwave background radiation

• The abundance of light elements

• All of the above

What is string cosmology?

• A theory that describes the behavior of strings in space

• A theory that combines relativity with quantum physics

• A theory that explains the formation of everything

• A theory about the existence of multiple universes

What are strings in string theory?

• Tiny particles that make up atoms

• One-dimensional objects that vibrate at different frequencies

• Large structures in space

• None of the above

How does string theory attempt to reconcile quantum mechanics and general relativity?

• By describing particles as tiny strings instead of points

• By proposing the existence of multiple dimensions

• By introducing the concept of wormholes

• By denying the validity of both theories

What is the ultimate goal of string cosmology?
