The Most Misunderstood Concepts in Physics
Sideprojects・2 minutes read
Physics, particularly quantum physics and astrophysics, can be complex, with theories often being mislabeled as hypotheses. Hypotheses are educated guesses requiring experimental confirmation to become theories, emphasizing that theories are subject to change and explain facts instead of being facts themselves.
Insights
- The distinction between theories and hypotheses is crucial in scientific discourse, where hypotheses are initial guesses requiring experimental validation to become theories, which undergo rigorous testing and peer review.
- Quantum physics, particularly evident in phenomena like Cherenkov radiation and Schrödinger's cat, challenges traditional understanding by showcasing complex and bizarre concepts such as particles surpassing light speed and objects existing in multiple states until observed.

Recent questions
What is the difference between a theory and a hypothesis?
A theory is a confirmed explanation, while a hypothesis is an educated guess that needs testing. The distinction lies in experimental validation.
Can particles travel faster than light?
Yes, in certain mediums like water, particles can travel faster than light, creating Cherenkov radiation. This phenomenon is observed in specific conditions.
What is Schrödinger's cat thought experiment?
Schrödinger's cat is a concept in quantum physics illustrating superposition, where an object can exist in multiple states until observed. It highlights the complexities of quantum mechanics.
Is String Theory a scientific theory?
String Theory is more of a hypothetical framework than a scientific theory. It requires rigorous testing and experimental confirmation to be considered a valid scientific theory.
Are scientific theories considered facts?
Scientific theories are not facts; they explain facts but are subject to change based on new evidence. The process of upgrading a hypothesis to a theory involves thorough testing and peer review.
