PeroK replied to the thread B How can a black hole absorb matter?.This is a serious misconception, albeit one promoted by many popular-science sources. -
PeroK reacted to Line_112's post in the thread B How can a black hole absorb matter? with
Skeptical.
But the whole trick here is that we are the external observers, not the little people falling into the black hole. For us, time does not... -

PeroK reacted to JimWhoKnew's post in the thread I Visual depiction of atomic orbitals with
Informative.
Divide your result corresponding to ##p_y## by ##i## (a global phase factor) and observe that now both expressions are real (and... -
