## What is the black hole equation?

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 Stephen Hawking’s theory of black hole formation?

That’s where Hawking came in. In 1971, he suggested that black holes formed in the chaotic environment of the earliest moments of the Big Bang. There, pockets of matter could spontaneously reach the densities needed to make black holes, flooding the cosmos with them well before the first stars twinkled.

**What is the Bekenstein Hawking formula?**

An important black hole observable is the Bekenstein-Hawking (BH) entropy, which is proportional to the area of the event horizon, SBH = Ah/(4G).

### Who gave black hole equation?

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).

### What is Stephen Hawking most famous equation?

It is also often written in the form S=k4l2PA, where lP:=√Gℏc3 is the Planck length, and called the Bekenstein–Hawking formula (Bekenstein conjectured the proportionality to A). The formula is related to Hawking’s work on black hole evaporation (“Hawking radiation”) back in 1973-4.

**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).

#### What is Stephen Hawking’s most famous theory?

The Big Bang wins

In his thesis, Hawking showed that the Steady State theory is mathematically self-contradictory. He argued instead that the universe began as an infinitely small, infinitely dense point called a singularity. Today, Hawking’s description is almost universally accepted among scientists.

#### What is Stephen Hawking IQ level?

Similar to Einstein, theoretical physicist Stephen Hawking had an estimated IQ of 160, yet it is unknown if he ever took an IQ test, according to enhancingbrain.com. According to Healthline, about 68% of people have an IQ between 85 and 115. The average IQ score in the U.S. is 98, says Healthline.

**What are the laws of black hole?**

The first law relates the mass, rotation and charge of a black hole to its entropy. The entropy of a black hole is then related to the surface area of its event horizon. The second law again states that the entropy of a black hole system cannot decrease.

## How do you calculate entropy of a black hole?

Entropy of Black Hole – YouTube

## 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. Since Penrose’s advances, astronomers have found a wealth of evidence for black holes.

**What is Ramanujan formula?**

In mathematics, in the field of number theory, the Ramanujan–Nagell equation is an equation between a square number and a number that is seven less than a power of two. It is an example of an exponential Diophantine equation, an equation to be solved in integers where one of the variables appears as an exponent.

### What is the equation that explains everything?

The Friedmann equation describes it all. Although Friedmann’s life was short, his influence cannot be overstated. He was the first to derive the General Relativity solution that describes our Universe: an expanding Universe filled with matter.

### Does the e mc2 equation apply to a black hole?

Putting E = mc2 into action.

**Does time Freeze in a black hole?**

Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.

#### When was the first black hole confirmed?

In 1971, astronomers discovered that the x-rays came from the direction of a bright blue star whirling around a mysterious dark object. They speculated that the x-rays were resulting from material being torn away from the bright star and falling onto the dark object, perhaps a black hole.

#### Who has 400 IQ?

Marilyn vos Savant (/ˌvɒs səˈvɑːnt/; born Marilyn Mach; August 11, 1946) is an American magazine columnist who has the highest recorded intelligence quotient (IQ) in the Guinness Book of Records, a competitive category the publication has since retired.

**What is Elon Musk IQ level?**

When did Elon Musk take an IQ test? The Tesla CEO is estimated to have an IQ score of around 155.

## 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.

## What is inside a black hole?

The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn’t really exist.

**Is the entropy of a black hole zero?**

But when mass enters the gravitational singularity (center of black hole), entropy is zero as space-time is at a standstill in a stable black hole. Therefore, as entropy is zero, the temperature becomes absolute zero (or possibly sub-absolute zero).

### 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. As stars reach the ends of their lives, most will inflate, lose mass, and then cool to form white dwarfs.

### Does time exist in a black hole?

(Phys.org) —The quintessential feature of a black hole is its “point of no return,” or what is more technically called its event horizon.

**What was the IQ of Ramanujan?**

185

Born in India in 1887, Srinivasa Ramanujan is one of the most influential mathematicians in the world. He made significant contributions to the analytical theory of numbers, as well as elliptic functions, continued fractions, and infinite series. He had an estimated IQ of 185.

#### Why is 3.14 called pi?

And how did it get the name “pi”? It was first called “pi” in 1706 by [the Welsh mathematician] William Jones, because pi is the first letter in the Greek word perimitros, which means “perimeter.”
