Gravity doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity. The ...

Decades in the making, a space probe that delves into Albert Einstein's general theory of gravitation remains grounded on Earth, caught in its own space-time continuum of technical snags, costly ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When it comes to a science like physics, theoretical expectations must ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...

As the story goes, Italian astronomer Galileo Galilei ascended the Leaning Tower of Pisa in the 16th century to drop two spheres of different masses at the same time—proving that they would land on ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...

Babies love it, and Galileo supposedly tried it: Drop some objects from on high, and see how fast they fall. According to Einstein’s theory of general relativity, all objects in Earth’s gravity, ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...
