big bang
If the laws of physics are symmetrical as we think they are, then the Big Bang should have created matter and antimatter in the same amount.
A new study proposes that Hawking radiation could be used to find dark matter in places like primordial black holes.
The controversy over the universe's expansion rate continues with a new, faster estimate.
Identifying primordial ripples would be key to understanding the conditions of the early universe.
The expansion of the universe is speeding up—contrary to what many physicists expected. A "heat death" is coming, but it's not what you think.
