The neutrons resist further compression by the Pauli Exclusion Principle, in a way analogous to electron degeneracy pressure, but stronger | Definition and overview The hypothesis relies crucially on the type of in the |

White dwarfs are stable because the inward pull of gravity is balanced by the of the star's electrons | Supermassive black holes, meanwhile, form differently - perhaps from the merger of many smaller black holes early in the universe's history - and grow over the years as they suck in gas from their surroundings |
The existence of black holes in the universe is well supported, both theoretically and by astronomical observation.
17At this point, the black hole is extremely tiny; a black hole with the mass of the Sun would fit in a small town | But both teams — the and the — found the same thing |

But measurements showed that these standard candles were not properly bright; they were fading | With dark energy, the expansion not only continues but accelerates |
The key value is the parameter , the between the dark energy pressure and its.
9The material inside the Schwarzschild radius will continue to collapse indefinitely, reaching the point where our understanding of the laws of physics breaks down | White and black dwarfs For a star of 1 solar mass, the resulting white dwarf is of about 0 |

And the Night as it gets Darker S | 6 solar mass, compressed into approximately the volume of the Earth |
Everyone knew since Edwin Hubble that the universe was being flung apart as a consequence of the Big Bang, some 13.
