Suppose that tomorrow we all discover the secret of time travel, and developed the technology to bring this dream to reality. Now that we have the capability, should one exploit it? I for one know that if I had the ability to travel to the past or future, I would be tempted to go to my past and try to fix past mistakes, and/or travel to my future and see what the world has evolved into. I'm sure that many of you would be similarly tempted. But, who has the right to tamper with events in the past that may put others, alive or maybe even unborn, at risk? If we have the capability, is it wrong to use it to our advantage? Just some food for thought.
