Cosmologists have predicted the existence of an oscillating signal that could distinguish between cosmic inflation and alternative theories of the universe’s birth.
Cosmologists have shown that it’s theoretically possible for a contracting universe to bounce and expand. The new work resuscitates an old idea that directly challenges the Big Bang theory of cosmic origins.
The first major results from the Dark Energy Survey signal the start of a new era of cosmology.
Daily bike rides, serendipitous interactions and long periods of solo thinking inspire this string cosmologist.
The story of the universe’s birth — and evidence for string theory — could be found in triangles and myriad other shapes in the sky.
Scientists haven’t tested the Big Bang’s light for a revealing shift in 25 years. A new experiment aims to change that.
No definitive evidence for cosmic inflation is found, but support remains strong for the theory even as critics highlight its shortcomings as an explanation for how and why the universe began.
Early in cosmic history, our universe may have bumped into another — a primordial clash that could have left traces in the Big Bang’s afterglow.
Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics.
