It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

NCERT books are considered the best source for clearing out the theoretical concepts and making the fundamentals strong. The questions and answers given in NCERT textbooks at the end of each chapter ...

What goes up must come down — though not always in the way you’d expect. This is Newton’s Universal Law of Gravitation, and you can thank it for GPS, Google Earth and even the pictures beamed back ...

[Translated by Dr. Robert W. Lawson.] MODERN physics renders it probable that the only fundamental forces in Nature are those which have their origin in gravitation and in the electromagnetic field.

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...
