As I understand it, dielectric breakdown voltage is the energy necessary to disrupt an insulator into a conductor. Therefore, if you have a perfect vacuum, there is no matter to disrupt. But, a high enough voltage could still create electron-positron pairs out of the vacuum and therefore make a conductor in something empty. It's called schwinger effect. It is only a prediction of quantum electrodynamics.

So if there is nothing there, electricity could pass through when "matter" (here electron and positron) are created in it.

More like |-1,0,1> because |101> would be |0>+2×|1> If I remember correctly

The expanse is awesomely accurate about spacetravels. A lot of great things in that show.

The analogy really ain't that good. Try with a water wave or a guitar string. If you pull a guitar string further the vibration it has gets a bigger amplitude but its mechanical resistance and border limitations won't change. This means the string will move faster or slower but it will oscillate at the same frequency.

Since the frequency is the same, the note is the same. But since amplitude varies, the sound is more intense.

Bar = unit of pressure. Isobar = same pressure everywhere. Baryon does not have the same roots. It is then Isobaryon but when talking nuclear physics you can shorten it because you usually don't talk about pressure so Isobar.

Consider energy. When you throw the ball in space, you give it kinetic energy (m*v^2/2) now unless an other force is applied on the ball at some point, this energy has no reason to disappear. It will not fade nor change. So it will keep moving forever.

On earth though, you throw the ball applying kinetic energy, but it also has potential energy (made by gravity as mgh) and air will apply friction energy opposite to the movement vector(proportional to f*v). As energy is conserved, it does not disappear, it will switch from kinetic to potential and inversely. Friction and hits will turn to thermal energy.

Found the answer online.

A Kerr black hole (one that rotates around its axis), has an ergosphere in which you can enter and get out because of the Lense-Thiring effect. Basically, the rotation of the black hole drags space-time and changes the frame of reference in which you move. Therefore if an object passes into the ergosphere it can still be ejected by gaining energy from the rotation.

But! If anything passes the event horizon, the surface limit where the escape velocity is the speed of light, then no material thing can escape.

In the paper they talk about other studies who found the same just without one of the comparison. I follow your train of thought on the rest: skeptical but not opposed to it being true.

Oh damn, we may go in the matrix, finally.
