New methods will allow for better tests of Einstein's general theory of relativity using LIGO data

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet Earth rolls around the sun ...

Laser physicists directly observe first femtoseconds after photoinjection

A laser pulse hits an electron in a solid. If it receives enough energy from the light wave, it can then move freely through a solid. This phenomenon, which scientists have been exploring since the beginnings of quantum mechanics, ...

Stephen Hawking and I created his final theory of the cosmos—here's what it reveals about the origins of time and life

The late physicist Stephen Hawking first asked me to work with him to develop "a new quantum theory of the Big Bang" in 1998. What started out as a doctoral project evolved over some 20 years into an intense collaboration ...

Entangled quantum circuits further disprove Einstein's concept of local causality

A group of researchers led by Andreas Wallraff, Professor of Solid State Physics at ETH Zurich, has performed a loophole-free Bell test to disprove the concept of "local causality" formulated by Albert Einstein in response ...
