    • If a particle is steady (not in motion), floating somewhere, does it make sense to talk about superposition and probability of finding the particle in a place x or y?
      If a particle is in continuous motion, why does it make sense to use probability to estimate/calculate its position? If it is in constant moving, it doesn’t have a position, but a trajectory, a path, therefore wouldn’t it be wrong to talk about and calculate a position?
      When you say that the electrons are in quantum superposition states, are you talking about the single specific electron? How sure can we be that we are observing the same electron?

    I have a question that maybe comes from something that i didn’t understand quite well or misunderstood.
    We said that at the moment the black holes collided a part of the collision energy was “used” to generate (or transformed) in gravitational wave (if i am not mistaken, the amount of ca. 3 solar masses). In the beginning of the lecture we said that in general gravitational waves don’t interact that much with matter. So, if they don’t interact that much (for whatsoever reason that needs to be discovered) and have so much energy and travel with the speed of light…. how can it be, that the force, that they exercise in the mirrors of LIGO is so small? Were did the whole energy go? was it converted everything to make the fabric of spacetime vibrate with the speed of light? If so, if we would have 3 solar mass and 6 solar mass of energy transformed in a gravitational wave, would the outcome still be the same?

    Thank you 🙂

    Thank You Professor Barish! Highly interesting, simply explained and very well presented. 🙂 Keep up the good work 🙂
