A phenomenon known as an "Einstein Ring" created when light is bent by gravity around a large object. In this case, the large red galaxy in the middle is causing light from a much more distant blue ...

Work close workEnergy transferred by a force. Work done = force × distance moved in the direction of the force. is done when energy is transferred from one store to another. Work is also done when a ...

Although we take a lot of scientific knowledge for granted today, each of the basics – whether it be about light, gravity, mass or the shape of the Earth – had to be theorized and experimentally ...

According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers ...

Gravity is a fundamental force of physics, one which we Earthlings tend to take for granted. You can't really blame us. Having evolved over the course of billions of years in Earth's environment, we ...

Our standard model of elementary particles and forces has recently become as close to “complete” as we could conceivably ask for. Every single one of the elementary particles — in all their different ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...
