The singularity at the center of a black hole is predicted to be a region of zero volume and infinite density that contains all of the black hole's mass. It is a point at which all currently known physical laws break down. Yet in a black hole, this "terrible point" is hidden from view behind an event horizon that prevents any knowledge about the singularity reaching the outside universe. Astronomers continue to spend considerable effort trying to understand the nature...

The supermassive black hole in the center of the Milky Way has a mass of roughly 3 million M⊙and the Milky Way is approximately10 billion years old. Estimate the average amount of matter accreted by the black hole per year since that time and use that information to propose modes by which the black hole has grown. That is, make some simple models which describe what the black hole might have eaten, and how much it has eaten as a...

A Black Hole has an event horizon, located at the Schwartzschild radius from the center of the black hole. The Schwartzschild radius of a black hole is proportional to its mass. We can write a handy version of this equation for stars in terms of Solar Masses as follows: R = 3M Where R is measured in kilometers and M in Solar Masses. So a 1 solar mass object (the Sun for example) if turned into a black hole would...

In April 2019, the Event Horizon Telescope collaboration announced that it had made the first spatially resolved images of a black hole, specifically the supermassive black hole in the center of the M87 galaxy. Using a wavelength of 1.3 mm, the EHT managed to achieve a resolution of approximately 1.2 x 10-10 radians.a) What is the diameter of the primary aperture of the EHT? How does this compare to the diameter of the Earth?b) Research the Event Horizon Telescope and...
