The eternal question..

I am of course referring to the question of time travel. What would it all mean if we could travel through time? lower flights around the world? a feeling that wasting all your time scrubbing the kitchen sink was done in vein? a 5 minute job could be done without wasting 5 minutes? Who knows? The point is scientists are working on how we can achive time travel.

"Hawking has suggested that time protects itself from such scenarios by preventing time travel to the past. Others suggest that the time traveler would simply enter a parallel universe that evolves along its own separate route in space. And others, like Halpern, say that past, present and future, might all exist and influence each other simultaneously in our universe."
