A provocative new theory suggests that the Universe may not have begun with a traditional Big Bang, but rather as a “Big Bounce” — the explosive rebound of matter collapsing into a black hole. Led by ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of ...

Stellar black holes are born from the collapse of massive stars at the end of their lives, weighing from 3 to 50 times the mass of the Sun. When a star exhausts its fuel, it explodes in a ...

Gravitational wave signals from the largest cosmic collision ever seen may alter our understanding of black holes, gravity, ...

LIGO observatory near Richland confirmed Einstein’s theory of relativity, it also has proven one of Hawking’s theorems.

The Schwinger effect reveals how vacuum fluctuations can produce real particles under strong electric fields, now explored ...

Perhaps for moments of quantum weirdness or when the characters are really jumping between different universes. This approach ...
