Gravitational Collapse Gravity, the weakest force known, may be the agent for crushing matter out of existence. This could happen after a star collapses to a critical size, whereupon gravity ...

Black holes are fundamental to the structure of galaxies and critical in our understanding of gravity, space, and time. A ...

and radiation pressure from the nuclear reactions tends to expand it outwards. In other words, the gravitational collapse is balanced by the expansion due to fusion energy.

In the case of a core-collapse supernova, the death of a massive star that has burned all its energy and collapses in a violent explosion, gravitational memory could give us insight into ...

Black holes are regions in space where an enormous amount of mass is packed into a tiny volume. This creates a gravitational pull so strong that not even light can escape. They are created when giant ...

When two enormous black holes collide in deep space, they send shockwaves rippling across the universe. These shockwaves, ...

Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.

Narrator: Serious scientists, like myself, believe our solar system was formed by the collapse of a giant cloud of gas and rock and is held together by the gravitational pull of the Sun.
