'Closed timelike curve' is the jargon for time travel. It means you go out, come back and meet yourself in the past.

I became interested in this question of whether you can build wormholes for interstellar travel. I realized that if you had a wormhole, the theory of general relativity by itself would permit you to go backward in time.

Don't time travel into the past, roaming through the nuances as if they can change. Don't bookmark pages you've already read.

I'm past the point of no return,

In the past two years, we have processed more than $2 million in travel claims directly related to hurricanes. Comprehensive travel insurance policies can protect your vacation investment, but like all types of insurance, you must buy it before the event is foreseeable.

We were really tired with all the travel we've had going on the past couple of weeks. We put that game behind us and didn't really think about it anymore. We wanted to come out here and play hard and let the chips fall where they may.
