It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

It describes two alternative models, proposes observational tests, and explores how this line of research could also contribute to the development of a theory of quantum gravity.

Furthermore, because gravitational interactions are weak, more precision is needed to study true quantum gravity effects beyond general relativity, which is a classical theory.

Before diving into the Raman Effect, it is important to first understand its background. It all started with the ‘Rayleigh scattering’, a theory proposed by British physicist Lord Rayleigh, in which ...

Physicist CV Raman was born on November 7, 1888. In 1928, C.V. Raman discovered the Raman Effect, a groundbreaking light scattering phenomenon, earning him the Nobel Prize in Physics (1930).

1. Raman Effect (1928) – His Most Famous Discovery Dr. Raman discovered that when light passes through a transparent material, a small fraction of the scattered light changes in wavelength.

Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model.

In 1896, the Swedish physicist Svante Arrhenius realized that carbon dioxide (CO 2) traps heat in Earth’s atmosphere — the phenomenon now called the greenhouse effect. Since then, increasingly ...
