When stars explode they become brilliant supernova for a short time, then they may undergo a sudden gravitational collapse into a neutron star or black hole, Astronomers are trying to catch glimpses of this happening, in case it happens to us in the future (In 2012? NOTE: Subscribers can still listen to this show).

We’re just starting to understand WHAT black holes are and HOW they are created. Scientists now suspect that at the end of this process of creation, time becomes "bent," meaning it actually STOPS. The future of time travel may hinge on understanding this (NOTE: Subscribers can still listen to this show). In space.com, Clara Moskowitz quotes mathematician Juan Antonio Valiente Kroon as saying, "It is really beyond the physics we know. To understand what happens inside a black hole, we need to invent new physics.read more
Astronomers are making wondrous new discoveries every day. A new study from NASA tells scientists how often the biggest black holes have been active over the last few billion years. This discovery could have implications for how the giant black hole at the center of the Milky Way will behave in the future. And is the expansion of the universe accelerating for some unknown reason? This is one of the mysteries plaguing astrophysics, and somewhere in distant galaxies are yet-unseen supernovae that may give us the answer.

New evidence about the origin of our universe suggests that time was created from the black hole in which it was born. In fact, our universe may be the inside of a black hole that exists in ANOTHER universe. This could be why we seem to be so alone (or are we?)
Technology Review website quotes physicist Nikodem Poplawski as saying (about the Big Bang), “Such an expansion is not visible for observers outside the black hole, for whom the horizon’s formation and all subsequent processes occur after infinite time.”
