cosmic string

Another theory is that a person could travel in time with cosmic strings.

He was responsible for the revival of the interest in cosmic strings.

First, I have seen reference to "cosmic strings", and was wondering exactly what these are.

"How could there be cosmic string in the middle of a void like this?"

But - what if it is cosmic string out there?

To do this, it would loop around the cosmic strings.

The cosmic string can exert pressure only when it is very near you, of course.

You will not in fact strike the cosmic string itself, I judge.

For example, it's possible the ring itself contains something like cosmic string.

In the proximity of cosmic string, nothing works as we know it.
