would it need to be, to travel around the world with no long stops, and always be in the dark? Following the night, as it were.
Theoretically, could you, in this way, be in a perpetual state of night? (darkness)

Please include sources, if any, and explain theories or formulas. No, this is not for homework help, merely curious as to the possibility...

It completely depends on your latitude. You would have to match the earth's rotation rate, one revolution per day. At the equator, that's about 1000 mph, at either pole it's 0 mph, and in between it's between 0 and 1000 mph. (Actually it's about 1000 mph times the cosine of your latitude.) Of course you can range north and south; you don't have to stay at one latitude. But the poles are tricky because of earth's tilt which brings seasonal variations in solar illumination. During spring and summer, at (and near) whichever pole it's spring or summer at, there is no night.
As for the mode of transportation, now you know the speed, you can choose.

Theoretically, the earth spins at appoximatley 500-600 miles per hour. In that contex, you would need a really fast plane witha large fuel capacity or an even faster boat with a large fuel capacity to stay in darkness. A plane would be more logical, but it would be heavy.

you'd probably have to match the speed of the rotation of the earth relative to your position of latitude on the planet
