Falling in Blackhole

 

please assume that if we go inside a black hole, what will we see? In today's video, we are going to see what happens inside a black hole, We had seen that when a stone is thrown towards a black hole, the light emanating from it is slowly getting reflected. If it is on fire due to it or due to its heat, then that light is slowly becoming red in colour.

 Its wavelength is increasing and the reason for this is that the black hole

There is a lot of gravity, the wavelength increases and at the same time, let me also tell you that as we go closer to the black hole, time will also become slow.

 Time will slow down. Now we move towards the black hole and go inside the black hole.

 Let us see what is happening inside the black hole. Let me tell you that it is written in our textbooks that usually it is also told that when you go inside a black hole, you will never be able to come out, rather your competition This will happen due to singularity and humans or anything else that goes inside the black hole will be destroyed. 

In any case, it cannot come out of the black hole even if it does not end, even if it does not end, it cannot come out of the black hole because the gravity of the black hole is very high, but a theory is telling us something about this. You see in this picture that we are going towards the black hole.

 When you are going towards the black hole, you will gradually slow down and a time will come when those who are watching you from a distance will feel that You have become visible on the boundary above the black hole, but they are seeing this because there is no trace of time here.

The speed is very low. You have entered inside the black hole. When you enter inside the black hole and you look back, you will see exactly the same stars in the sky as were seen outside the black hole.

 Something special. There will be no difference, but you may find the position of the stars different because as soon as the light goes inside and near the black hole, it bends a lot, hence you may see their location at different places, but apart from this, you will not feel much difference. Yes, you will feel one more thing and that is that you will feel that

The black hole is very big, and it has a very high volume, just like we see in the story of Alice in Wonderland in which Alice goes into a rabbit hole and inside there is a very big castle, outside there is a small door, inside there is a lot of black holes.

 There is a big palace, just like this, the mouth of the black hole will seem small to you, but when you go inside, you will find that the volume of the black hole will be so much that its volume will be huge. An example of this can also be given from a well whose mouth is very small. But inside it is very big. You enter inside the black hole.

 

When you enter inside the black hole, you will also see that there are some parts of the black hole, one part is a funnel, I am showing you the black hole here, so the boundary of the black hole is called the event horizon.

 It is said that you can go back beyond the event horizon but you will not be able to go back further because the gravity is very high and below it, there is a funnel and at the end of the funnel there is a singularity. Einstein's General Theory of Relativity tells us these things but Today we will look at the black hole from another perspective. I will show you the picture of the black hole here.

 

If I were showing you, when you entered inside the black hole and started seeing the geometry of the black hole, you would feel that the volume of the black hole was gradually increasing but its tail is increasing, and the tunnel which is there is increasing slowly. This is the same thing that you can see from this funnel shown in the picture here, see its tail, how long its funnel, how long is the funnel of a black hole, it can be millions of light years, and you can travel in it in millions of light years. If nothing happens to you and you survive, you can travel for so long, and then you

If you can hit the end of a black hole, then the end of the black hole is not infinite, it is finite, its funnel is finite and you can hit its end. Second surprise, a surprise, you will get that the funnel is getting bigger.

 The second surprise you will get is that you are stuck in a black hole. The black hole's funnel is shrinking. Okay, it is getting longer and thinner, now it is shrinking. Now you have come into a problem because of so much. The funnel will shrink so much that it will crush a person or anything so before we reach the end

They may have ended in a black hole, but what is present at the end of a black hole? Einstein's theory tells us that there is a singularity, but if we look at the history of black holes, then black holes are formed from the death of big stars. I am taking you here.

 I am moving towards a cycle and in this cycle, you can see that small stars do not form black holes but white holes are formed when they die and have passed their life but the big stars do not form those stars. can either form neutron stars or black holes if it

The star is 20 times bigger than our Sun, so when it explodes through a supernova, that is, it dies, then we will get a black hole from it and there will be fun in that black hole.
