We don't know. We can go back to within nanoseconds of the Big Bang, around 14.6 billion years ago, but that event makes it impossible to go further.

Whether to only a couple of weeks, or another 20 trillion years, or for an infinite time, is up to what you think.Or possibly a loop in time,Where future and past come together.
