The truth about the planet you call home is that it is more bizarre than you think. From dark matter to the endless universe, our world is made up of unseen external forces that humans are still not able to understand entirely. Thus, we have enough unsolved earth mysteries to discover for those who love to uncover strange mysteries!
So, in the class, 'Unbelievable Events', we are going to reveal some interesting yet strange mysteries about planet Earth that will thrill your mind. What if we tell you that our 4-billion-year-old planet isn't eternal and may celebrate its last birthday sooner or later? Well, the end of the world remains one of the biggest mysteries that are still unexplained. The ‘Big Crunch’ theory suggests that the expansion of the universe which has been going on since the Big Bang will fall into the force of gravity. As a result, everything – planets, universes, stars – will be pulled together into a sole, dense point of mass, to the point where everything is put to an end. Don't be afraid though, all of this is at least a billion years away!
