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 ...

II. WE have to admit, then, that a world-line can be bent by the proximity of other world-lines. It can also be bent, as you see, by the proximity of my thumb. The suggestion arises, May not the two ...

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 ...

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 ...

Gravitation is a force by the virtue of which objects get attracted towards each other because they have mass. There are various laws and principles which govern this attractive force in the whole ...

Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies -- it sounds daring, but one physicist has proposed ...

The Panel on Particle Astrophysics and Gravitation (PAG) will identify and suggest to the Astro2020 decadal survey committee a program of federal investment in research activities exploring areas at ...

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 ...
