Black hole equation

What is a black hole mathematically?

A black hole is a region of spacetime where the force of gravity is so strong that nothing, not even light, can escape from the region. Black holes are formed when a lot of mass is concentrated in a tiny region of space.

What is the radius of a black hole?

approximately 12 million kilometres

Would a black hole kill you?

Curiously, the black hole’s enormous gravity itself is not what will kill you–you are always weightless when in free fall. Instead, you would be pulled apart as a result of the difference between the force of gravity at your feet and at your head.

What are 2 types of black holes?

A black hole is an object whose gravity is so strong that nothing, not even light, can escape it. Astronomers have long thought that black holes come in just two kinds, the “stellar” and the “supermassive.” The type depends on the weight of the black hole, or more specifically, its mass.

Will a black hole hit Earth?

There is no danger of the Earth (located 26,000 light years away from the Milky Way’s black hole) being pulled in. Future galaxy collisions will cause black holes to grow in size, for example by merging of two black holes.

What’s inside a black hole?

According to theory, within a black hole there’s something called a singularity. A singularity is what all the matter in a black hole gets crushed into. Others say that the singularity is actually a whole surface inside the event horizon.

How much force does it take to create a black hole?

In principle, a black hole can have any mass equal to or above about 2.2×108 kg or 22 micrograms (the Planck mass). To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light.

How big does a black hole need to be to destroy Earth?

A BLACK hole just one millimetre in size would destroy Earth, ripping the planet up bit-by-bit and “completely killing us”, an expert has warned.

Can a black hole kill Superman?

He has enough power to create life, or his own universe, for that matter. P.S. even the regular Superman can survive a black hole. Since nothing can escape a black hole after touching the event horizon,not even light Superman have to fly with a speed greater than that of light than he may have a chance.

Does time exist in a black hole?

Black holes are so massive that they severely warp the fabric of spacetime (the three spatial dimensions and time combined in a four-dimensional continuum). For this reason, an observer inside a black hole experiences the passage of time much differently than an outside observer.

How can you kill a black hole?

For a black hole, any matter entering the event horizon is added to the mass. Shoot bullets at a black hole, and you just make a slightly more massive, slightly more dangerous black hole. Detonate a nuclear bomb inside the event horizon, and you only make the black hole more massive.

What are the 4 types of black holes?

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death.

What is the heaviest thing in the universe?

So massive stars become neutron stars – the heaviest things in the universe – and even more massive stars become black holes.

Find the real solutions of the equation

What are real solutions of an equation? How To Solve Them? The “solutions” to the Quadratic Equation are where it is equal to zero. There are usually 2 solutions (as shown in this graph). Just plug in the values of a, b and c, and do the calculations. What does it mean to find all […]

Write an equation for the polynomial graphed below

What is the formula for a polynomial function? A polynomial is a function of the form f(x) = anxn + an−1xn−1 + + a2x2 + a1x + a0 . The degree of a polynomial is the highest power of x in its expression. What are examples of polynomial functions? Basic knowledge of polynomial functions Polynomial […]
