Beginning and end of time.

History of time
  Time can be defined as 'the duration of an action' in classic physics & as a 'part of space-time in modern physics'.Time leaves some unanswered questions to us.For example ,

Was there a beginning of time?
Could time run backwards?
Did time is just a property of energetic particles ?
Can we travel through time?

The big bang theory suggests that time beginned 'after' it.
(there is a possible arise of question on the word AFTER, as its a word for representing time.But AFTER/BEFORE are words used for comparing an event with actual time).

Some scientists and also theories like 'Quasi Steady State theory' had suggested that time existed even before big bang and big bang is just a usual phenomenon on the universe.


Some people even suggests that "there was a big bang even before the original big bang and hence there was a universe before the present universe & that universe crunched(the cosmological term is BIG CRUNCH) and then expanded into our current universe & our present universe may once again undergo big crunch were time&space may end or reemerge as a new , young universe "
