Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern ...

In physics, the evolution of the universe has so far been described by the general theory of relativity and the so-called Friedmann equations. However, in order to explain the observed expansion of ...

What's needed to determine the shape and geometry of our universe? We know the universe will continue to expand forever, so now we can begin to complete the first Friedmann equation, and determine the ...

The past 20 years have seen dramatic advances in cosmology, mostly driven by observations from new telescopes and detectors. These instruments have allowed astronomers to map out the large-scale ...

(via Science Asylum) Believe it not, Einstein originally thought the universe was static. It would take Alexander Friedmann to correct him. Here are the Friedmann equations, explained simply.

I'm studying for my Qual (12 days to go and counting), and currently slogging through cosmology. Something that was never explained to my satisfaction earlier is how ...

“The equation is called the Friedmann equation and, simply put, governs the expansion of space in a homogenous universe such as our own. In the 1920s Alexander Friedmann, a Russian astrophysicist, ...

In images widely being circulated on social media, students of Beijing’s Tsinghua University can be seen holding sheets on which is written one of the Friedmann equations. Tsinghua University is a ...
