In Paul Steinhardt’s corners of the cosmology world, to say that history repeats itself would be a laughable understatement. That’s because according to him and a handful of peers, the universe’s form ...

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

For a generation, cosmologists have worked with a simple story: the universe is not only expanding, it is expanding faster ...

TACC's Frontera supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structures in the universe. Example Lyman-α forest spectra from ...

Tiny temperature variations found in maps of the cosmic microwave background are commonly thought to be proof that stars, galaxies and other large-scale structures grew from density perturbations in ...

Scientists made a twin version of our universe, showing the evolution of all forms of matter and energy, in the biggest cosmological computer simulation to date. When you purchase through links on our ...

A few decades ago, astronomers realized they had a problem: They could not find enough matter in the universe to account for all the space in between stars and galaxies. The missing mass begged the ...

As evidenced by the diagrams that make up the Tree of Knowledge System, I think it is valuable that we teach individuals broad frames to think about the Universe and our place in it. That was why I ...
