M-Theory | how to test string theory | dark matter | dark energy | Wormhole

In the last post on “ string theory ” we discussed many things like the super symmetry, higher dimensions, strings, need for the theory of everything, different versions of string theory and many more. I request you to first read the previous post and then read this because this is the continuation of it.  There are many different string theories and that’s a big problem. We need only one theory that can explain everything in the universe. Today we will discuss such an attempt named M-Theory. We will also discuss how string theory explains blackhole, dark matter, dark energy, wormholes, etc. How to test the string theory? And many more things… But before that we need to know… What are branes?  String theory takes into account the 1-Dimensional strings but the M-theory takes branes into consideration. Branes are the fundamental basis of nature but with higher dimensions than strings. Branes can be any dimensional starting from 0 to 9 dimensions.  Branes can have electrical...

Can we escape the universe??

Image
The fate of the universe is destined - the universe will end sooner or later. What if we could escape the universe? The multiverse is big and different universe will end at different time, so there is a chance of saving humanity. The known universe is 93 billion light years wide. If we are able to travel faster than light then also it will take minimum 93 billion years to reach the end of the known universe. The age of the universe is about 14 billion years, so you can imagine the thought of escaping is so bizarre. But what if I say you there are some options using which we can escape the universe?  As we have discussed we have plenty of time before universe meets its fate, so we can start planning from now. our present technology is not at all capable of any interstellar travel but in the future we can become capable. There are several types of civilizations which are capable of escaping the fate, if we advance to become one of those types, we can do what we desire. Let’s take a...

what is the fate of the universe? How will universe end??

Everything which starts must end. Every story has a climax, may it be a movie or life, book or the universe. The universe started with the big bang and is expanding since then. There will be a time when it will die as everything else.  Why would t his happen in the first place? How will universe come to end? What will happen to the humans and other living beings? How can we save ourselves? we will try to find the answers to all these questions.  Let’s get started…  Why will the universe die?   The second law of thermodynamics states that the total entropy of the universe always increases. Entropy means the degree of disorder in everything. In simple words, everything must age and run down. Let’s take some examples and try to understand entropy: - * When coffee falls on the floor, its entropy increases .  * When you successfully arrange all the pieces of Jigsaw puzzle, its entropy decreases .  * Ice melts into water, its entropy increases   * Coal burn...

Bermuda Triangle: a mystery or a hoax | facts of bermuda triangle

Image
Bermuda triangle has always been a mystery. Many planes and ships have went missing. Many people have lost their lives. What is the reason behind all these mysterious disappearances? Is there an alien base camp? Are the people of Atlantis responsible? Or Is there any scientific explanation behind all these disappearances? There are many movies made and books written highlighting these reasons. We will take a look at some of the theories and find out the facts. We will try to get the real reason behind all this.  Let’s get started… WHAT IS BERMUDA TRIANGLE?   Bermuda triangle is an area made up of the imaginary line joining Florida , Bermuda and Puerto Rico . It is also called Devil’s triangle . This is not the official area and It is mentioned differently by different writers. It is not mentioned in the map as "Bermuda triangle". The term "Bermuda Triangle" was coined by Vincent Gaddis in 1964 for a magazine article. The name eventually got popular after many ...

Natotechnology is the future technology | Nanobots | Nanomaterials | Nanomedicine

I don’t know why but we have a fantasy to miniaturize the electronic things. Just compare the mobile phone in 2000s and that of 2020, size has changed but performance has improved exponentially. There are many sectors where this technique is used (miniaturization) . The technology is improving while the size is decreasing.  There is a technology that is continuing the trend being millions of times more efficient. This is the sector where many countries are investing 1/3rd of their research budget. Japan increased its investment by 6 times in this sector. India, China and South Korea are at the front to become masters of this technology. The technology and sector I am talking about is NANOTECHNOLOGY .    You must have heard of Nanotechnology if you have watched the movies like Black Panther, Infinity War, Transformers, Terminator, etc.   What is Nanotechnology?  “Nano” means 1 billionth of a meter (0.000000001 meter). The human hair is 10 millionth of a met...
