Why do you expect neutron stars to spin more rapidly than white dwarfs? Why do you expect neutron stars to spin rapidly? Neutron stars are formed by the collapse of massive stars. Since all stars rotate, the principle of conservation of...
What is the lighthouse model? Lighthouse Model community homes are a form of long-term housing for people with serious mental illness (SMI). They are located in safe neighborhoods and run smoothly and efficiently resulting in a good relationship with the neighbors....
What is the lighthouse model of pulsars? The widely accepted model to explain them is the lighthouse model, involving a rotating, very dense neutron star that emits a highly focused beam of radiation. We can only see the beam when it...
Why do we expect that neutron stars spin rapidly? We expect neutron stars to spin rapidly because they conserve angular momentum. Do neutron stars spin very rapidly? The power from the supernova that birthed it gives the star an extremely quick...
How are a neutron star and a white dwarf similar? If a supernova’s remnant is 1.4 to about three times the sun’s mass, the remnant becomes a neutron star. Like white dwarfs, neutron stars are dense. But a neutron star is...
How heavy is a neutron star in KG? Neutrons stars are extreme objects that measure between 10 and 20 km across. They have densities of 1017 kg/m3(the Earth has a density of around 5×103 kg/m3 and even white dwarfs have densities...
Why is there a supermassive black hole in every galaxy? They are believed to be at the center of every galaxy because they have such gravitational power and strength that they can pull the rest of the dust, asteroids, planets and...
What happens if a human go into a black hole? A jump into a black hole is a one-way trip. Black holes are regions of space where gravity is so strong that nothing can escape them, not even light. Even before...
Is the universe inside a black hole? Our Universe appears to be expanding and cooling, having originated some 13.8 billion years ago in a hot Big Bang. However, it’s plausible that what we see from inside our Universe is simply the...
Who proved black holes exist? ‘” Roger Penrose (left) proved black holes are real objects. Andrea Ghez (center) and Reinhard Genzel (right) showed that one weighing 4 million times as much as the Sun lurks in the heart of our galaxy....
