 Hi Guys, today I am going to tell you about:- DO BULLS REALLY HATE RED? Bulls are partially colourblind, they can only see the shades of yellow,  green, blue, and violet  colours. They can't see RED. Then, why do they attack when we wave a red cloth in front of a bull. It is not the colour that makes them angry instead it is the wavy motion of the cloth which makes it angry. Even if we wave a cloth of any colour still it will get angry and try to attack us. It is the survival instincts that provoke them when they see wavy motion. And they are also very aggressive. THANK YOU!

 Hi Guys, today I am going to tell you about:- WHAT IS ELECTROMAGNETIC RADIATION? If you have not read my post about light, then you can  read it now . Electromagnetic radiation is a stream of photons which moves in a wave is called electromagnetic radiation. The photons are the quantum of electromagnetic radiation or the energy carrier.  Photon is an elementary particle and is the energy carrier of electromagnetic radiation. And it has no mass, means it is a massless particle. As you can see in the above image that the wavelengths of radio waves are bigger than gamma rays. This happens due to the variation of energy of photons. When the photons have a short wavelength, the energy is very high like the gamma rays and as the wavelengths increase in size, the energy of photons decreases like radio waves. So we can say that the bigger the wavelength, the less energy it has and shorter the wavelength, the more energy it has. I hope that you might have understood. THANK YOU

 Hi Guys, Today I am going to tell you about:- WHAT IS LIGHT? This will be a short post. So light is something that helps us to see. We have not yet properly defined light. Light is generally electromagnetic radiation . But what is this electromagnetic radiation? Electromagnetic radiation is generally a wave-energy that can travel through a vacuum . I will tell you about electromagnetic radiation in my next post. If we want to know about light , we should know about the electromagnetic spectrum . The electromagnetic spectrum (Or the spectrum of light) contains the visible light , infrared , radio waves etc. You might be getting confused. But read till the end. Light consists of photons , which travels in the form of a wave . You all might know that wave has a wavelength . The wavelength decides the type of light that is emitted from an object. So the different wavelength of light is put in the electromagnetic spectrum like radio waves , ultraviolet radiation , visible ...

Hi Guys, today I am going to tell you about:-  IS DARK ENERGY REALLY DARK? I have already told you about dark energy and dark matter . So today I will tell you about why is it called dark. Dark energy and dark matter does not interact with electromagnetic radiation like light and many other things. So if it does not interact with light, then the light will be not affected by dark energy or dark matter and neither it will be reflected, hence we can't see it. So it is called 'Dark'. And this is also the reason why dark energy and dark matter is very difficult to find, even though it is present abundantly. --------------- A request If anyone does know about blender, then please tell me on how I can make a space-time fabric in blender 2.8 .    Please................................................ please................................................ --------------- THANK YOU

Hi Guys, welcome to 'Tech With Rob'. Today I am going to tell you about :- WHAT IS OUR UNIVERSE MADE UP OF ? I have already told you about ' How Our Universe Was Formed '. So today let's look at what are the basic things in our universe. Our univerrse is made up of :- 1) Normal Matter (approximately less than 5 %) -   The things we can see like the sun, stars, trees, cars etc. 2) Dark Matter (approximately 23 %) -   I have not told you about dark matter yet, It produces a attractive force like gravity. 3) Dark Energy (approximately 73 %) -   I have told you about this in ' Beginning Till The End Of The Universe ', I had said that dark energy is the culprit behind expansion of our universe and produces a repulsive force due to which our universe is expanding. So, In my next post I will tell you about why is it called dark energy or matter.  And I am working on the video, I have downloaded a video editing software ' OpenShot ' and it is free. But it wi...

Hi Guys, I am very sorry for being late................. I thought that I should also make some videos and put that in this blog, as this my first time trying to edit videos, so It will take a while to make videos. Till then I will tell you easy-peasy concepts. THANK YOU

Hi Guys, today I am going to post the second part of :- IS TIME TRAVEL POSSIBLE ? (Part-2) I am very sorry to be late. So let's start the journey of time travel . If you have not read my first post on ' Is Time Travel Possible ' then click the link below -- Is Time Travel Possible? As I have told you that it is easy to travel into the future than the past . So first let's talk about the future.... Time Travel Into The Future......... There are mainly two ways to travel into the future .  I t would not look like time travel but more like slowing the time . When we travel very fast at the speed of light ( 186,282 miles per second ) the time moves slower compared to others . This is called time-dialation. Imagine that your in a rocket which can move at the speed of light . If you don't know anything about the speed of light then click the link below -- Speed Of Light ! You are travelling at the speed of light . And you went to a far away galaxy ...

Hi Guys, today I am going to post about :- SPEED OF LIGHT ! This is going to be a short post . Which is the speedest object in the  universe ???? The speed of light is  186,282 miles per second ( 299,792 kilometers per second ). The speedest object in this universe is light . And no one can go faster than light and the speed of light is not relative it is constant . I will explain it more deeply . THANK YOU

Hi Guys, today I am going to post about :- Is Time Travel Possible ? So in my post ' The Grandfather Paradox (Answer) '  I had asked you that can we travel in time ?? ---This going to be a very small post. Yes , time travel is possible . It is easy to travel into the future compared to travelling into the past . But we can't now travel in time , but we can travel in time in the future. You may have many questions about this, I will tell you about the concept of time travel in my future posts. THANK YOU  

Hi Guys, today I am going to post the answer of :- THE GRANDFATHER PARADOX   If you have not read my first post on 'The Grandfather Paradox'  then click the link below :- https://rugber.blogspot.com/2020/05/Grandfather%20Paradox.html   So let's start............................ I believe that you might have read the post mentioned above.  So when you travel back in time to the childhood of your grandfather's period , you reach in a different universe (dimension) , I have told about this in my post about ' The Parallel Universe '. The level-3 parallel universe and also told you that every decision takes you into a different universe . Like that when you travelled back in time, you reached in a different universe and you did not killed your grandfather , but the grandfather in a different universe .  And the grandfather in your universe will be safe , Hence your father will be born and you will also be born . So, you will not die if you went into th...
