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...

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...
