Tech With Rob

Hi friends, today as I have said I am going to tell you about :-  HOW DOES THE ARC REACTOR WORK ? I have told you that arc reactor is a device to harness the nuclear energy. High temperature and pressure is needed for the fusion of two hydrogen nucleus (mainly deuterium and tritium). Deutrium and tritium are the isotopes of hydrogen. In short, these are the different types of hydrogen. There are three types of hydrogen :- 1) Protium 2) Deuterium 3) Tritium For fusion high temperature and pressure is needed, So to get this high temperature scientists use electromagnetism for achieving this heat and pressure.  The above image shows the fusion reactor. As you can see there are big coils around the hydrogen container in this coils high voltage is passed through the coil which heats the hydrogen gas, at 100 000 kelvin the hydrogen gas gets converted to plasma. Plasma is the fourth state of matter, I will tell you about...

Today I am going to post on the topic about :- "Can We Make A Mini Arc Reactor ?" First of all what is a arc reactor, a arc reactor is a way of harnessing the energy produced by the nuclear fusion of two Hydrogen atoms, the same process which happens in the core of the sun. It is the cleanest energy than all other energy. It can produce upto 1 gigawatt (1000000000 watts) of electricity. But this technology is not used in the present, because for the process of fusion very high teperature and pressure is needed like the core of the sun. And the energy invested for this is more than the output of the process. Recently, we have acquired this high pressure and temperature, six times the pressure and temperature core of the sun. But to acquire this type conditions more electricity is used than the output. So, we don't harness energy by this technology. But we can overcome this problem in the future, and by overcoming we can creat...

Today I am going to post a topic about :- THE BIG BOUNCE THEORY I have already told you about the big bang theory, so today I will explain another theory called the Big Bounce. The Big Bounce Now you know that our universe was formed by a rapid expansion. And it is continuing to expand due to the force of dark energy.  And that the universe will either collapse (big crunch) or rip apart or nothing will shrink or expand.  In short the theory says that the present universe will shrink (The Big Crunch) again into singularity due to gravity and again from the singularity the expansion (The Big Bang) will happen and again energy will be converted to matter. Forming a cycle of expansion and shrinking  (The Big Bounce)  into singularity. But if the force of gravity is less than the force of dark energy, then this theory would not workout because according to this the big bang has happened several times.  THANK YOU 

Hello friends, as I have promised I am going to post my topic about :- BIG BANG THEORY, NUCLEAR FUSION, BLACK HOLE I have told you about the big bang theory, nuclear fusion and black hole. I am re-introducing these concepts so that you have a better grip in these things So as I have said that our universe was formed by a rapid expansion or also you may say a explosion also. Before the Big Bang there was no universe there was only space and point of singularity and nothing else. In this singularity was the whole universe. But we don't know how was the point of sigularity been formed we only knew that it was there.   Then gradually, the singularity started expading rapidly due to the dark energy. It is a mysterious energy and we don't know anything more about the dark energy. The Dark Energy During the Big Bang there was matter and anti-matter, but now there is only matter, no anti-matter. Some scientists think that while the expansion the matt...

Hi friends, Sorry for the long delay for posting new topics because my exams was going on, and another reason is that I had left my hope in blogging. But now I am back with a strong will power. I promise you that I will post a new topic on 19th March 2020 THANK YOU

Hello  friends,  today I am going to post about :- BLACK HOLE Black hole Some of the sub-topics are :- 1) What Is A Black Hole      - How is a black hole formed?    - About black hole 2) Where Is Our Nearest Black Hole? 3) What Is Light Years? What Is A Black Hole Black hole is formed when the fuel (hydrogen) gets over in the cores of the stars, as there is no fuel, to oppose the force of gravity it starts to shrink and forms  a black hole or a neutron star . It has a very strong gravitational force, even light also can't escape from the gravitational force of the black hole. I have told you about this in my post called 'Nuclear fusion in stars' or you may see this video to know more about how a black hole is formed . Where Is Our Nearest Black Hole? The  closest black hole  we know is V616 Monocerotis , also known as V616 Mon . It's located about 3,000 light years away, and has between 9-13 t...

Hello friends, today I am going to post about :- 'NUCLEAR FUSION IN STARS'  This is nuclear fusion.  Some of the sub-topics that I will introduce to you are :- 1) Do Stars Need fuel?        - Why do stars need fuel?    -What is the fuel of the stars  2)What Is Nuclear Fusion?    - What happens in nuclear fusion    - Is nuclear fusion important? 4) An Amazing Fact 3) What If The Hydrogen Gets Over In The Core? DO STARS NEED FUEL? As we know that everyone needs food or fuel for energy, like that stars also need fuel to generate energy. WHAT IS NUCLEAR FUSION This process of generating energy is called nuclear fusion . This process only takes place in extreme temperatures . In this process the hydrogen in the core of the stars gets squeezed together producing helium atoms which produces a lot of energy in the form of light . Therefore, hydrogen is the fuel of the st...

Hello friends, today I am going to post my first topic about :- "HOW  WAS THE UNIVERSE  FORMED OR THE BIG BANG THEORY"  The big bang theory Some of the sub-topics that I will introduce to you are :- 1) About The Word 'THEORY' - From where did the word 'THEORY' came from?            - Meaning of Theory.  2) About the big bang theory - Who proposed the big bang theory and when was it proposed? - What is the big bang theory? 3) Is the universe expanding?  - Will big bang happen again? If yes, then how? ABOUT THE WORD 'THEORY' The word ' Theory ' was derived (came) from a Greek word .  Theory means  a supposition or a system of ideas intended to explain something. In simple words it means that a idea which is used to explain something, it is only a expectations or suggestions of scientist, for example from where did the earth got water but we don't know...

Don't be afraid of darkness, because one small light is enough to end the darkness.   H i friends,   It's my first  blog. So I  want your full support and don't forget to comment below. From now onwards I will mainly post about science facts. And you can comment if you want to know about any other topics. I will try my best to post latest science facts and I will try to improve my blog.       THANK YOU
