So quantum tunnelling is one of the ways of putting erect the hypothetical concept of Hawking radiation. But what actually happens inside a black hole, since not all the mass and energy trapped within gets radiated out ?

Black HOLE and not black whole

Hi everyone, It might be very impractical but still I want to ask it. When a ray of light enters a perfect hypothetical reflecting box through a small hole ( that doesn't diffract it), the ray gets trapped if that hole is closed soon. However due to the very strange phenomenon of quantum tunnelling the light ray may come out ( i.e. tunnel out) if we are to leave the box undisturbed for infinite period of time. So the inference is that a light ray cannot be trapped within a closed box for infinite period of time. Now let's take the case to a black hole. A ray of light approaches the event horizon of a supermassive black hole. It enters into it and gets trapped within a very weird space-time curvature inside the black hole. So will this ray of light escape out of the event horizon by quantum tunnelling? Thanks in advance for your thoughts.

In India, a large portion of the rural women commit suicide due to the burden of their in-laws. Torture and mental torment causes the women to think to die and end the life. There are even cases where people commit suicide in order to get relief out of mental depression or some fatal unsocial activities. People consider suicide illegal and unethical. But, I put forward a question - Every human has got the right to life. So why they shan't be given the right to die ?

How many roads must a man come down before you call him a man That's Bob Dylan.

Well that's correct.....

Correct. 5worlds.

Hello I got an interesting puzzle here. ;-) A short man takes three steps to a tall man's two steps. They both start out on the left foot. How many steps do they have to take before they are both stepping out on the right foot together ?

Hi, Can anybody make 1000 by using sixteen 4s ??

Hi Bryce I see you got a good imagination. And you are also interested in physics. You can understand physics a lot better if you learn calculus. Good Luck !

Stay here for a few months and you will get used to English.

First you must know that pi/2=90 degrees. Now proceed.

I believe that Donald Trump will never win.

A good poem. +1

I believe that I will succeed if I work hard with full determination and self-confidence.

So now I get that. Thanks for all your help.

Optic nerve is a nerve fibre that connects the retina with the visual cortex of the brain and transmits the impulses. On a computer wires are used for transmitting data ( although there is a wide range of options available to transfer data wirelessly). So, how can an optic nerve help ? But, optical fibres may be useful.

Many archaeological evidences prove that we humans are animals, we are mammals, we evolved from the Cenozoic Era about 11.2-14.6 mya. Our earliest ancestors were the descendants of Australopithecus, with slightly little better brain and intelligence. It is interesting to note that the Hominines evolved so much time before, whereas the Homo sapiens developed only 200000 years ago. However the Bible says that humans had evolved from Adam and Eve.

OK And the other condition ?

Hi, I want to know why is the Riemann hypothesis still unsolved? I really want to know the reasons due to which it is still unsolved.

There must be two numbers a and b such that a^2 - b^2 = n^3 and a^3 - b^3 = m^2 , m and n are two different numbers.
