As I explained in my previous blog, the universe consists of 5% normal, visible matter in the form of stars, planets, moons, asteroids, and galaxies, etc. Moreover, another 25% of the universe consists of Dark Matter which is invisible to our eyes. This type of matter is basically, a postulated form of matter that interacts with its surrounding space through gravitation. However, the remaining 70% percent of the universe comprises of Dark Energy, which is another great mystery of the universe and the most fascinating one, in my opinion.
Whilst Dark Matter has the power to hold the universe together, Dark Energy has enough power to tear up the whole universe.
Basically, the universe as we know it came into existence through a great explosion that we know as the Big Bang which ejected a large amount of matter and energy. Due to the inertia of this humongous explosion, the universe is expanding. However, according to the laws of Physics, this inertia will have to reduce gradually to an extent that it comes to a stop but, this is not the case here. The speed of the expansion of the universe is increasing at great speeds instead of slowing down. To get an idea of how fast it is getting, I'll share the fact that at some places, this expansion is taking place at speeds that are even faster than the speed of light which is, quite shocking. Therefore, scientists performed complex calculations and research and derived the fact that there is something behind this phenomenon and hence, Dark Energy was founded. The culprit behind the ever-increasing speeds of the expansion of our universe.

Dark Energy is very powerful and it has enough power to rip the whole universe apart. The origin of this energy, however, is still a mystery as scientists are totally baffled by it. Recent researches assume the collision of quantum particles as the source of this mysterious energy, however, this is still an ambitious prediction due to the fact that we don't yet have the technology to observe such phenomena. Therefore, the origin of this mysterious energy has not been found yet. a
