On teleporting to another universe:
On black holes:
Black holes are the hydrogen atoms of quantum gravity
On black hole firewalls:
... from the Page time onward there
is no spacetime within the black hole

has been
that it gives us no inkling of why the 'nice
time slice' argument
supporting local physics for large black holes is apparently wrong
