How massive would a black hole have to be in order for it to evaporate due to Hawking radiation in only one year? How big is that mass compared to some object with which you are familiar? (On the surface of the Earth, 1 kg ? 2.2 lb.)

One "extreme" example of gravity is a black hole. What would happen to the Earth's orbit if the Sun was suddenly replaced by a black hole of the same mass? Why? (Please ignore any processes that the Earth would experience during the formation of the black hole.) Please break it down for us dummies

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...

Describe, in detail, what would happen if you fell into a black hole, from both your perspective, and the perspective of someone who is watching you fall in. You should include specific effects, including effects on space, time, and what you would see.

Is the "event horizon" of a black hole potentially violable? Black holes are commonly described as being unidirectional (matter / energy goes in, but doesn't come out), but is the event horizon of a black hole potentially deformable? That is, in the case of two black holes colliding (let's say), is there not a point when the effective gravitational field between the two black holes "cancel out", thereby causing a potential "escape path" for light traveling perpendicular to the axis...

They are primarily formed through accretion of matter C. The are primarily formed through merging of smaller black holes. D. They have been formed during the Big Bang What properties of a Black Hole can you determine theoretically 1. Mass, magnetic field, and spin 2. Mass, Spin, and electric charge 3. Mass,...

What is the mass of the black hole at the center of our galaxy if a star orbiting 0.0025 pc away has an orbital period of 7 years? Be careful of units here.

A black hole has an event horizon radius of 3.00

Which of these are actual evidence for the existence of a black hole in the center of the Milky Way, and which are not? Stars are observed to disappear into the black hole Bright quasar emission is detected from the center of the galaxy Telescopes have been used to take high resolution images of the black hole's event horizon Astronomers observe an extremely bright and compact radio source The closest approach of stellar orbits near the center of the galaxy...
