Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival, explains what we know about time travel so far. Following is a transcript of the video.
Time is linear...it is always moving forward...time can NEVER flow backwards. The perceived rate of time movement is the so-called "time travel" mentioned here. Instead of 1 second for 1 second...it would be perceived as being faster or slower...compared to the actual rate of 1-to-1. But that difference is only perceived by the individual experiencing the event that is effecting the 1-to-1 rate. For everyone else time flows normally.
