The Science of Doctor Who

The science of *Doctor Who* blends real physics and speculative ideas to create engaging stories. Time travel is central, often explained through concepts like wormholes—shortcuts through spacetime—or the TARDIS, a time machine that’s also a 'dimensional shift' device. The Doctor’s encounters involve advanced alien technology, parallel universes, and the manipulation of matter and energy at fundamental levels. While many ideas are imaginative, they draw on scientific principles such as relativity and quantum mechanics, inspiring curiosity about the universe’s possibilities—not as established facts, but as creative interpretations grounded in scientific theories.
