Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the quantum ground state energy?The minimum energy a quantum system can possess, characterized by continuous fluctuations
2. What is the theoretical origin?A consequence of the Heisenberg uncertainty principle and quantum field theory

Quantum Field Theory (QFT): A framework combining quantum mechanics and special relativity to describe fundamental particles and forces.
Heisenberg Uncertainty Principle: States that certain pairs of physical properties, like position and momentum, cannot be simultaneously known with perfect accuracy.
Cosmological Constant Problem: The significant discrepancy between the theoretically calculated vacuum energy density and the observed value driving cosmic acceleration.
Casimir Effect: An attractive force between two closely spaced, uncharged conductive plates in a vacuum, caused by ZPE fluctuations.
