Creation of wormholes by quantum tunnelling in modified gravity
... It is important to stress that in a toy model containing just one scalar field coupled to gravity, both Jordan and Einstein frames are physically equivalent and whether or not necks in the geometry exist may be seen to depend on the choice of frame. It is the coupling of gravity to the rest of matte ...

A Plunge Into a Black Hole
... Gravitational redshift Photons always travel at the speed of light, but they lose energy when traveling out of a gravitational field and appear to be redder to an external observer. The stronger the gravitational field, the more energy the photons lose because of this gravitational redshift. The ex ...

... Stellar mass black holes: only seen when material is falling in producing an accretion disk. This happens when, for example, a star (originally bigger than about 5 solar masses) has a companion and draws in material from the other star. X-rays are produced as the material heats as it fall in. ...
