sorry, but I don't really know how to question this. it is just that my teacher have asked me to research about it, but i can't find anything relevant on the other website, so i asked at this forum.

What is high energy electron scattering?

what do you mean averagesupernova?

oh ic, thanks a lot ^^

could it be because the coil vibrates?

If a transformer has loose parts, then a hum is heard while there is current flowing through the primary coil. how do you explain this noise?

What is the einstein-rosen bridge?

i am just concerning that if there is black holes, is there white holes as well?
