Hi Guys, today I am going to post about :- PARALLEL UNIVERSE Universe Prallel universe is a theory which simply says that there many other universes (multiverse) other than our universe ... In this universe  at this time you are  reading , but in the other universe you might be a sleeping , eating  or anything you can think about or you might have not been born yet. So in simple words we can say that parallel universe is a dream land where everything is possible .  Scientists have divided the parallel universe  into 4 levels :- 1) In this level there are many copies of yourselves in different universes , doing different things, like I told you before.  And the rules of physics and nature is same in all these parallel universes . Parallel Universe (Level-1) 2) In this level it is said that all parallel universes including our universe  is inside a big bubble . These bubbles either breaks or joins together to form a new parallel univer...

Hi Guys, today I am going to tell you about :- HOW IS THE UNIVERSE EXPANDING ? You all might know about the big bang theory , if you don't know about the big bang theory then click the link below :- https://rugber.blogspot.com/2019/10/how-universe-was-formed-big-bang-theory.html So you all might know that our universe is expanding very fast, greater than the speed of light.   According to Einstein no object can travel faster than the speed of  light , So does the expansion of the universe violates einstein's theory ?? Not really, the object on the universe can't travel faster than light but the universe itself can expand faster than light . The expansion of the universe should have stopped in some years after the big bang , but the expansion has not yet stopped . Why?? Why is the universe still expanding ??   The universe is still expanding due to a mysterious force called the dark energy , scientist yet don't know anything about the dark energy .   ...

Hi Guys, I am thinking that I should tell you about Nanotechnology . If you want to learn about Nanotechnology, then comment down below. Only If you comment, I will introduce to you the world of nanotechnology. THANK YOU  

Hi Guys, today I am going to post the second part of SPIDER-MAN CLIMBING SUIT (PART-2) If you have not read part one then click the link below https://rugber.blogspot.com/2020/05/Spider-man%20climb.html So I had told you that we can't make structures of that small, but we can really make structures that is small as few nanometers using nanotechnology . But the other problem is that we should cover over whole body with these small hairs, is this the end of our dreams ??? Not really, if we reduce the diameter of the structure to one nanometer. But we can't make structures of one nanometer (It might be possible in the future). There is a substance, whose diameter is only one nanometer - Carbon Nanotubes Therefore, if we used carbon nanotubes the total Van Der Waals Force will increase. But, this force is not enough to climb on walls. So, this is the end of our dreams.    I can't believe this, but what if we increase the force between two poralised atoms (Van Der Waals Force). ...

Hi Guys, today I am going to post the second part of :- WILL EARTH FALL INTO THE SUN ? (PART-2) If you have not read the posts related to this topic, then you can click the links below :- 1) Centipretal And Centrifugal Force  https://rugber.blogspot.com/2020/05/Centripetal%20And%20Centrifugal%20Force.html 2)  Will Earth Fall Into The Sun https://rugber.blogspot.com/2020/05/.Is%20Earth%20In%20Danger%20.html I believe that you might have read the above posts.  As the centifugal force increases, the marble will revolve around the object for a longer period of time. And when centrifugal and centrifical forces become equal the marble will obtain a steady orbital path around the object until an external force is acted on it. Note that the, Centrifical force is the curvature of the space-time fabric (Gravity). And if the speed of the earth increases then it will escape the force of gravity. THANK YOU

Hi Guys, today I am going to post about :- SPIDER-MAN CLIMBING SUIT I have already told you that we can climb using technology and also how do spiders climb wall. If you have not read it then click the link below   https://rugber.blogspot.com/2020/05/How%20do%20spiders%20crawl%20.html                                                           and https://rugber.blogspot.com/2020/05/Van%20Der%20Waals%20Force.html So if we make a gloves which has small hair like structures which is only a few nanometers thick, then there is a chance, that we could climb the wall like spider-man. The few nanometers thick hair will increase the surface area of contact, increasing the Van Der Waals force. This force will oppose the force of gravity, hence climbing the wall. But the problem is that we can't make structures (hairs) this small. And to oppose gravit...
