What does string theory propose as the fundamental component of the universe?
Electromagnetic fields
Waves of gravitational force
Vibrating strands of energy known as strings
Tiny particles called atoms
Who was responsible for unifying electricity and magnetism into electromagnetism?
Albert Einstein
Niels Bohr
Isaac Newton
James Clerk Maxwell
What significant theory did Einstein develop that redefined gravity?
Electromagnetism
Classical mechanics
Theory of relativity
Quantum mechanics
What fundamental principle does quantum mechanics introduce that differs from classical physics?
Particles can exist in multiple states simultaneously
Gravity is the strongest force
Time is absolute
Energy is continuous, not quantized
What new forces were discovered that are essential at the quantum level?
Strong and weak nuclear forces
Gravitational and electromagnetic forces
Frictional and centripetal forces
Thermal and radiant forces
Why is it challenging to unify general relativity with quantum mechanics?
They operate on different scales of size and strength
General relativity fully explains quantum phenomena
They are fundamentally the same theories
Quantum mechanics does not allow for the force of gravity
What is a major challenge in proving string theory?
It aligns closely with Newtonian physics
Strings are observable with current technology
It only applies to large astronomical objects
Strings are too small to be observed with current technology
