The Science of Time Explained by Brian Greene

Theoretical physicist, mathematician, and string theorist Brian Greene explains the technology science of time. As a general definition, time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. Brian Greene simplifies the concept of time so we can have a better understanding of it.

In general relativity, the physical nature of time is addressed with respect to events in spacetime. For example: The collision of two particles, the explosion of a supernova, or the arrival of a rocket ship.

Brian Greene also explains if its possible to time travel. One of the most frequent questions people wonder when thinking about time is whether its physically possible to go back in time. But a central problem with time travel to the past is the violation of causality.

As for going back in time, it is in direct violation of causality. Giving rise to the possibility of a temporal paradox. Some interpretations of time travel resolve this by accepting the possibility of travel between branch points, parallel realities, or universes.
