Do the strings in String theory get energy to vibrate from Higgs?

    Just as particles move through the theoretical Higgs field and gain energy which gives them mass, do the strings in String theory get their energy to vibrate from the Higgs Field as well? And does that mean that the Strings have mass?

    Strings do not have mass. Instead, they are characterized by a quantity that is called "tension". Gravity and matter with mass, similar to the matter which we see in our universe, emerge from strings.

    OK I expected that they wouldn't have mass and I know that their vibrations decide the amount of mass in particles but where does the energy come from to make the strings vibrate?

    It is simply assumed that they have energy. The important thing is that energy is conserved.

    So there is no explanation yet?

    Don't they define a squared mass for the string states, and so on get the predicted spectrum of the theory?
    I don't know, I don't really like the idea of "tension".

    I agree, I think the question has no answer yet. Guess I just need to be patient.

    The answer to your question is in general no.
    Although the Higgs mechanism can work on string theory (in order to break symmetries), the strings don't need the Higgs interaction to gain mass. Their mass is a result of their vibration modes.

    And what makes the strings vibrate?

    the fact that they are allowed to by the way you deal them- you allow them to vibrate with some boundary conditions.

    So....is their Any theory to there vibrations or is it only assumed without an explanation.

    no vibration is just one possibility out of the many you are allowed to have by accepting it. I don't understand what's your point. Non vibration would be for example a zero-th mode. The question would be more likely to ask yourself why you want to take just one case out of the infinite possibilities?
