“Time Is On My Side,” The Rolling Stones (1964)
First recorded by Kai Winding and his orchestra in 1963 with background singers Cissy Houston, Dionne Warwick and Dee Dee Warwick, “Time Is On My Side” was also covered by soul singer Irma Thomas before The Rolling Stones recorded it for their album 12 X 5. In the song, the narrator knows his love will return, because he believes he has time on his side.
Time Travel Is Possible: Physicists Simulate Sending Light Into the Past.
Single particles of light (photons) to simulate quantum particles travelling through time were just used by scientists from the University of Queensland, Australia.
They showed that one photon can pass through a wormhole and then interact with its older self.
One aspect of general relativity that has long intrigued physicists is the relative ease with which one can find solutions to Einstein’s field equations that contain closed timelike curves (CTCs)—causal loops in space–time that return to the same point in space and time.”
Closed timelike curves are a necessary concept to understand this experiment.
CTCs are used to simulate powerful gravitational fields, like the ones produced by a spinning black hole, that could theoretically (based on Einstein’s theory of general relativity), warp the fabric of existence so that space-time bends back on itself. This creates a CTC, almost like a pathway to travel back through time.
The source of time travel speculation lies in the fact that our best physical theories seem to contain no prohibitions on traveling backward through time. The feat should be possible based on Einstein’s theory of general relativity, which describes gravity as the warping of spacetime by energy and matter. An extremely powerful gravitational field, such as that produced by a spinning black hole, could in principle profoundly warp the fabric of existence so that spacetime bends back on itself. This would create a “closed timelike curve,” or CTC, a loop that could be traversed to travel back in time. (source)
Experimenting With CTC’s
Single particles of light (photons) to simulate quantum particles travelling through time were just used by scientists from the University of Queensland, Australia. They showed that one photon can pass through a wormhole and then interact with its older self. Their findings were published in Nature Communications.
Much of their simulation revolved around investigating the “grandfather paradox,” a hypothetical scenario in which someone uses a CTC to travel back through time to murder her own grandfather, thus preventing her own later birth.
