Previously we discussed Arthur Eddington and his expedition to measure the gravitational lensing effects of the Sun during a solar eclipse. The results were in agreement with Einstein’s predictions from General Relativity, which catapulted Einstein into the public eye and established General Relativity as the fundamental explanation of gravity in terms of the curvature of space and time. 2,328 more words

#### Curvature operator and gravity coupled to a scalar field: the physical Hamiltonian operator by Alesci, Assanioussi and Lewandowski

This week I been reviewing some conference proceedings the FFP14 Conference, Marseilles 2014. One paper I particularly like is this one by Alesci, Assanioussi and Lewandowski. 530 more words

#### Quote of the Century : Gravity Does not Exist in Space

I was in 8th grade when I was taught and even Understood gravity. Hence no man claiming to have no college education can even think of such a line. 230 more words

#### 10 Mind-Bending Discoveries In Physics

The study of physics is the study of the universe—and more specifically, just how the hell the universe works. It is without a doubt the most interesting branch of science, because the universe, as it turns out, is a whole lot more complicated than it looks on the surface (and it looks pretty complicated already). 2,188 more words
