| Video Discription | Brian Cox - Traversable Wormholes as Time Machines SUBSCRIBE to "Science Time": https://www.youtube.com/sciencetime24 Physicist Brian Cox explains the science behind time machines and wormholes and whether it's theoretically possible to use traversable wormholes for time travel. Brian Cox gives details about our understanding of time and the seemingly asymmetric passage of time known as the "arrow of time" and why it flow only in one direction. Brian Cox also explains known paradoxes that might arise when dealing with time travel such as the grandfather paradox. It occurs when the past is changed in any way that creates a contradiction in causality. For example, if you travel into the past and intervene with the conception of your ancestors (such as causing the death of the parent beforehand), you would be affecting the conception of yourself. If you as the time traveller were not born, then it would not be possible for you to undertake such an act in the first place. Scientifically speaking, Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. So is time travel possible? Without any cliffhangers, the answer is absolutely, YES...Time travel into the future that is. However, time travel to the past, is a different story entirely. Some theories, most notably special and general relativity, suggest that suitable geometries of spacetime or specific types of motion in space might allow time travel into the past. If wormholes exist, a type 3 civilization on the Kardashev scale could use them for intergalactic space travel and also, time travel. #wormhole #ProfBrianCox #timemachine Sources: https://www.youtube.com/watch?v=uQSoaiubuA0 https://www.youtube.com/watch?v=YFOeXZUlrKY&t=0s https://www.youtube.com/watch?v=GEFB4s4NrPw "Professor Brian Cox" by University of Essex is licensed under CC BY 2.0.
