Quote of the day by Stephen Hawking: If time travel is possible, where are the tourists from the future? - How a simple question by the genius scientist challenges the possibility of time travel in real life

Stephen Hawkings famous question is the quote of the day, as it reflects his skepticism about traveling backwards in time. He used this idea to argue that if time travel were truly possible, there should already be evidence of visitors from the future in our present world. Since no such signs exist, it raises doubts about whether backward time travel can ever happen, and ties into his broader ideas about physics and the limits of the universe.
