Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a ...
“The cosmological principle is like an ultimate kind of statement of humility,” explains James Adam, astrophysicist at the University of the Western Cape, Cape Town, South Africa, and lead author of ...
Modern cosmology reveals a universe expanding uniformly without a spatial center or edge. The Big Bang wasn't a localized explosion but a simultaneous ...
CC0 Usage Conditions ApplyClick for more information. One of the fundamental ideas of cosmology is that everything looks the same in all directions if you look over large enough distances. A new study ...

So how many stars are there? Given all of the above, astronomers estimate that the Milky Way contains around 100 billion stars, and there are at least 100 billion galaxies in the observable universe.
The Einstein–Gauss–Bonnet framework extends Einstein’s theory of General Relativity by including a higher-order curvature term that gains dynamical relevance in dimensions beyond four. This approach ...
