To conduct this simulation, researchers used a theory called quantum field theory in curved spacetime (QFTCS). Essentially, this theory allows us to study how particles behave in a universe where ...

If this scenario plays out, “the world as we know it would collapse like a house of cards,” says one theoretical physicist.

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

CFT stands for conformal field theory, which describes quantum physical systems whose ... A branched electrical circuit is used to mimic curved space-time—the electrical signals at the ...

A new theory links gravity to quantum entropy and introduces the G-field, possibly explaining dark matter and cosmic ...
