A scientist claims he might have figured out the solution to the ‘grandfather paradox’

Time travel has fascinated humanity for generations, but it’s long been dismissed as impossible due to the "grandfather paradox." This thought experiment poses a mind-bending question: what happens if you travel back in time and prevent your grandfather from having children, thus erasing your existence?

The paradox seemed insurmountable—until now. However, a new study combining general relativity, quantum mechanics, and thermodynamics suggests time travel might sidestep such contradictions.
