these objects represented some of the earliest light ever glimpsed by humanity—originating from between 600 million and 1.5 billion years after the Big Bang. There was just one problem ...

they may have unleashed enormous amounts of water that flooded the early universe — and potentially made life possible just millions of years after the Big Bang, new simulations suggest.

Physicists have performed a groundbreaking simulation they say sheds new light on an elusive phenomenon that could determine the ultimate fate of the Universe.

Scolnic, an associate professor of physics at Duke University, explains it as trying to build the Universe's growth chart: we know what size it had at the Big Bang, but how did it get to the size ...

A crucial metric for comprehending the evolution of the universe since the Big Bang is the Hubble constant (H0 ... which calls into doubt our knowledge of cosmology. The universe seems to be expanding ...
