In 1916, almost immediately after Einstein released his theory of general relativity, the German physicist Karl Schwarzschild found an exact solution to the equations that describes what we now know as a black hole (the term wouldn’t be invented for another five decades).

## Does E mc2 apply to black holes?

Does the E=mc^2 equation apply to a black hole? E=mc^2 is always true. In the case of a black hole, for instance, there has been some speculation that black holes can, through a quantum mechanical trick, radiate energy, and in the process their mass would therefore decrease.

## What is the physics behind black holes?

A black hole is a region of spacetime where gravity is so strong that nothing – no particles or even electromagnetic radiation such as light – can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

## What laws of physics do black holes break?

Black holes obey all laws of physics, including the laws of gravity. Their remarkable properties are in fact a direct consequence of gravity. In 1687, Isaac Newton showed that all objects in the Universe attract each other through gravity. Gravity is actually one of the weakest forces known to physics.

## Is there a formula for a black hole?

R S ( M ) = 2 G M c 2 , where G is the gravitational constant and c is the speed of light. It is okay if you do not follow the details of the equation; the basic point is that if you put an amount of mass M or larger in a sphere of radius smaller than RS(M), then voila—it will become a black hole.

## What is a black hole mathematically?

The Schwarzschild radius is, more or less, the size that a given object, with a given mass, should have in order for it to be a black hole. For instance, if we managed to concentrate all the mass of the Earth into a sphere of a radius of a few centimetres, then that object would be a black hole.

## What happens if mass is added to black hole?

As the mass increases, so does the gravitational pull and objects require more energy to reach escape velocity. When the mass is sufficiently high enough that the velocity needed to escape is greater than the speed of light we say that a black hole has been created.

## Is a black hole mass or energy?

Massive black holes in the centres of galaxies release so much energy that they play an important role in how the galaxy around them evolves. As well as being impressive objects in their own right, black holes provide unique laboratories for testing strong gravity and matter under extreme conditions.

## Do black holes convert mass to energy?

When gas or other material falls past the point of no return (called the event horizon) and into a black hole, the exact amount of energy (including mass) contained in the material as it falls in is added to the black hole. So the total amount of energy in the system doesn’t change.

## What breaks the physics law?

A new study suggests subatomic particles called muons are breaking the laws of physics.

## Do black holes defy laws of thermodynamics?

When a black hole absorbs matter is it destroying that mass, thereby destroying energy, therefore violating the first law of thermodynamics? No. It destroys the matter, but the total mass stays the same, as does the total energy.

## Does time stop in a black hole?

Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.

## What is stronger than a black hole?

The most powerful supernova yet recorded (ASSASN-15lh) was 22 trillion times more explosive than a black hole will be in its final moments. It doesn’t matter how small or how massive a black hole is, their closing fireworks are exactly the same. The only difference is how long it will take a black hole to explode.

## Does Blackhole break physics?

The researchers said: “Our conclusion appears to be at once startling and undeniable: global charge conservation cannot be guaranteed in the presence of axionic electromagnetic interaction.” For more on this research, read Throwing an “Axion Bomb” Into a Black Hole Could Break a Fundamental Law of Physics.

## Whats at the end of a black hole?

The boundary of a black hole is its event horizon. It is not a physical edge. It’s just a point in space beyond which it is impossible to escape the black hole’s gravity. Once anything falling into the black hole passes the event horizon, it can never leave the black hole again.

## How much time is 1 second in a black hole?

Even if we see the universe from a point very close to the apparent event horizon, the time dilates to such an extent that the time of the locations away from tne universe will be much faster (say 1 second for the observer near blak hole will be 100000 years for an observer on earth).

## How much force is needed to create a black hole?

The energy necessary to produce such a black hole is 39 orders of magnitude greater than the energies available at the Large Hadron Collider, indicating that the LHC cannot produce mini black holes.

## Can a human create a black hole?

To study the phenomenon more closely, physicists in Israel managed to create a lab-grown, analogue black hole using some thousand atoms. This faux black hole exhibited all properties of a black hole in the state in which it is believed to exist in space.

## What is the equation for dark matter?

Calculation of dark matter 2 / 2 = (tu/tp)2 /2 = 0.32×10122 [1, pg. 30]. This value corresponds to the value of dark matter in Table 1, where HDM = 0.33×10122 is given.

## What are 2 types of black holes?

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.

## How does time pass in a black hole?

According to Einstein’s theory, time and space, in a way, trade places inside the hole. Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.

## Do black holes have infinite mass?

Well, even though black holes are extreme in many ways, they don’t have infinite mass—and it’s mass that determines the force of their gravity. Some black holes—known as stellar black holes. —have about the amount of mass that very massive stars do.

## Do black holes change the speed of light?

When light passes by a black hole, its speed doesn’t change, but its path curves. Astronomers have directly observed this bending of light around massive objects in space (here’s a !).

## Do black holes bend light?

Light rays that pass close to the black hole get caught and cannot escape. Therefore, the region around the black hole is a dark disk. Light rays that pass a little further away don’t get caught but do get bent by the black hole’s gravity.

## Do black holes have magnetic fields?

Astronomers have found that the magnetic field strengths near supermassive black holes can be as strong as their intense gravitational fields. In fact, these magnetic fields are able to expel material from the vicinity of the black hole to form highly energetic outflows called ‘jets’.
