Quantum Foam – Definition & Detailed Explanation – Astronomical Units & Measurements Glossary

I. What is Quantum Foam? Quantum foam is a term used in theoretical physics to describe the turbulent and fluctuating nature of spacetime at extremely small scales. According to quantum mechanics, at the most fundamental level of reality, spacetime is not smooth and continuous, but rather composed of tiny, ever-changing bubbles of energy and spacetime … Read more

Redshift-Space Distortion – Definition & Detailed Explanation – Astronomical Units & Measurements Glossary

I. What is Redshift-Space Distortion? Redshift-space distortion is a phenomenon in astronomy that occurs when the observed redshift of galaxies is affected by their peculiar velocities. In simple terms, redshift-space distortion refers to the apparent stretching or compression of galaxy clusters along the line of sight due to their motion through space. This distortion can … Read more
