Ans: Until some time back, astronomers thought that the universe was composed of electrons, protons, neutrons, ordinary atoms. Nevertheless, inside the previous handful of decades, this theory has taken a significant turn as there is a lot additional to this universe than just the basic stuff of life.
The universe is really a culmination of three substances: regular matter, dark matter and dark energy.
The typical matter involves all of the visible objects within the universe like stars, planets, human beings. They are all produced up of protons, neutrons and electrons. Strangely the standard matter constitutes only 4% of your whole proportion on the universe; in conjunction with dark matter which constitutes roughly 24% and the dark energy would be the enormous some 70%.
The dark matter is composed of one or far more species of sub-atomic particles that interacts quite weakly with ordinary matter. The dark energy includes a gravitational repulsive impact, which results in the flatness with the universe and it is accelerated expansion.
The universe still remains unexplored and we don’t understand how far we’ve got to go to comprehend our Universe. It really is still a box of surprise to us. We do not know what all secrets are waiting to become unlocked.
