In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.—Douglas Adams,The Restaurant at the End of the Universe One of the biggest questions in physics is why anything exists at all. This is not a question about wheth...

structure of matter, and interaction between fundamental constituents of the observable universe is known as Physics. Physics is taken from the Greek word 'physikos' which means the study of physical sciences, or "Knowledge of Nature", and that's why in a broad sense, it can be said Physics...
MT 6 LT 1 Mechanical Waves What are waves?
Wave-Particle Duality in Brief As mentioned above, light has properties of both a wave and a particle. This was an astounding discovery and is certainly outside the realm of how we normally perceive things. Billiard balls act as particles, while oceans act as waves. Photons act as both a ...
Dark matter constitutes over 80% of all matter in the universe, yet it remains unseen by scientists. Its existence is inferred because, without it, the behavior of stars, planets, and galaxies would be inexplicable. Here is what we know about it — or rather, what we think we know. ...
Phenomenon is perhaps the only correct term to use in describing its explosive burst into life, sending its shock waves and flaming brands literally across all of Europe and, eventually from there, far and wide into the whole world. Patriotism is a precursor to nationalism. Perhaps the closest...
What happens to waves when there is refraction in bays? Wave Refraction: Wave refraction refers to the change in the direction of waves as the medium through which they travel changes. This change in direction is accompanied by changes in the speed and wavelength (also wave properties/characteris...
Optical physics is the study of light and its interaction with matter. Most of us think of light as an illuminating energy. With light, we can see things. Without it, we’re in the dark. To optical physicists, though, light is a series of electromagnetic waves that vary widely in their...
The galaxy cluster Abell 1689 is famous for the way it bends light in a phenomenon called gravitational lensing. A new study of the cluster is revealing secrets about how dark energy shapes the universe.
