Just suppose you murdered your grandfather............

..........after you had travelled back in time (after the advent of time-machines, of course) before he had had any children? Where does that leave you? How could your childless grandfather be murdered by one of his grandchildren?

Modern research into quantum physics has proposed one way around this paradox by viewing the universe as a `multiverse` in which all possible histories happen simultaneously. A time traveller could then travel into the past, but only into the past of another parallel universe in which he, a time traveller who was not born there, kills his grandfather. This theory is gaining acceptance among quantum physicists and has contributed to a renaissance of scientific interest in how the laws of physics could permit time travel.

Idea of time travel was first considered scientifically as a result of Einstein`s theory, which demonstrated that gravity warps the fabric of space-time. The same theory also said that under certain circumstances, such as inside a rotating black hole, the warping becomes so severe that space-time is torn and folded back on itself, providing pathways into the past.


Makes you think, dunnit?

Theoretically,. Petal, yes, if you know what you are doing. But not very likely. You can probably change your own life to a certain extent.
