Space Voids

Doctor Ales Pasani Whenever she is finished, she goes to her lab, picks up virtual reality glasses puts them on her eyes, and starts exploring the universe through these headsets. Yes, I am taking you towards the augmented software that they have created themselves, and through this software they roam around in the universe. They see galaxies everywhere, stars are visible in the galaxy, solar systems are visible, and black holes are visible. are visible but while roaming around it is such a

 

Reach a place where nothing exists, from where we cannot see light, the rays of light are not reaching us, and there are neither galaxies nor stars, these areas are called voids i.e. areas where there is nothing. Doctor is very fascinated by going here, she is very much interested in these areas because she wants to know how these areas are formed. Let me tell you here that Ales Pisani is an astrophysicist and his work is that It computes, collects data and

 

She finds different types of patterns in it and is a computational astrophysicist. She has made this simulation with one of her students. The name of this student is Bonnie U Wank, who has made this simulation. It is an augmented reality model of the universe. These two face each other. It happened at the Cooper Union of Advancement of Science and Art in New York City and then Pisani invited the bank to come and make these simulations for me. I provide you the data. They had a lot of data. They gave 100 million light-years of data to the bank.

 

Provided, that is, if you are standing here, the light that will travel for 100 million years, now you take it in a circle and take it in a complete circle because I told you the radius, he provided the data of all the galaxies inside it so that we can use an augmented software. To make it possible, let me tell you that augmented software is currently giving us very little information about voids, but till 1980, we kept understanding that there is something present inside the voids, they are completely empty and we do not see any kind of visible matter here. No kind of galaxy comes here

 

There are no solar systems of any kind here, but today we know that there are galaxies inside them, there are also solar systems inside them, but they are so few that they appear completely different to us from a distance. Our interest also increased because we feel that perhaps from these places we can get many interesting clues about some new things. In fact, I am talking about dark matter. Only 5 percent of our universe is made up of visible matter. i.e. the things that we see, the sun, the moon

 

Stars support black holes but 27 percent of it is made up of a method which we cannot see, which we cannot test, with which any type of matter cannot interact. It is called dark matter and 67 percent of it is dark energy. The interest in these voids is due to dark matter because we think that perhaps it can give us some information about dark matter. I want to draw your attention. The Standard Particle Model is such a model of physics in the Standard Particle Model. Which tells us what our universe is

 

Particles are made up of very small particles ranging from sub-atomic particles to very small particles. The most important particle which is very important in the context of this video is called a neutrino. If you can see here, you can see that you can also see particles. You may be seeing cox, you may be seeing leptons, but at the same time, you are also seeing the forces that are produced due to the interaction of these particles and at the same time, you are also seeing hex bosons here, but If we come to the bottom row, you will find Leptos here and these Leptos

 

You will find three types of neutrinos: Electron and Tau neutrinos are also called ghost particles and the reason for this is that they are passing through my body millions of times. They are also passing through in a very short time but they do not interact with matter. Their speed is close to the speed of light, but because they are neutral and do not interact with matter, we do not know that neutrinos are born. Stars Neutrinos from star's fusion reactions

 

Are born and let me also tell you that they travel at almost the speed of light. When we talk about this void, we not only have the idea that we are going to get some information about neutrinos from this word. We will discuss this further in the next videos of this series as well and these words can prove the General Theory of Relativity given by Einstein to be true. Now we have seen the General Theory of Relativity on a small scale that it holds and we see that it is present everywhere and we can prove it experimentally.

 

But proving the General Theory of Relativity on such a large area is of great interest to scientists because there is no matter in the sheet of space-time. Due to this, the behavior of light is different. This behavior is not different from any law, but the type of behavior that the General Theory of Relativity tells us, does light behave in the same way? Scientists are very interested in this thing too. I am telling you this. Let me also tell you that the voids were discovered in the year 1970 and at that time, scientists were very fond of them because they believed that the universe

 

It is as if we see it almost everywhere and when the scientists, while exploring the universe, first came across the void, they were completely shaken because now the universe is no longer homogeneous, they felt that it is a very There is a big hole in his thinking because he thought that the way galaxies and glowing objects are visible everywhere in the universe, there is no such area in the universe which is different from this, this is what gives us the Cosmic Microwave Background. Radiation also tells that this is the light when the universe was formed.

 

Immediately after that explosion, this light was born, approximately 38 thousand years later, this light was born from the Big Bang, and till today this light is traveling and reaching us, but now this light is not in the visible range because when this light was born approximately Sometime before 14 billion years, this light is coming to us with a lot of information, but the universe is slowly expanding and when the wave of light is passing through the universe and reaching us, the space-time is expanding, that too. Slowly she is getting stretched, and now her cycles are getting bigger.

 

Its wavelength is getting bigger and it no longer remains in visible light. When we move the waves of this light which have now come into the microwave, they first get stretched and go into the infrared, then get further stretched and come into the microwave. Because it is coming to us from a very long distance, it is coming to us from a distance of about 14 billion years, so now it has gone into the microwave band and when we see it, we get a plot from our space stations and Spacecraft has made a complete map and when we see CMB in that map, it is

 

They appear absolutely homogeneous. We do not see any place where there is nothing. We do not see the void here in that way, so we feel that the entire universe is homogeneous and this is what our lodges are also telling us. Then it is so. What is that we suddenly found a very big part inside which there is nothing present, which is very different from the rest of the universe, where the density of Galaxy S is not the same as we find in the normal universe. The voids raise a big question. But the answers to these questions are based on our theory.
