Physicists say that only 5% of this universe is created of matter or atoms (electrons, protons, and neutrons). Then what is the rest 95% made of if not atoms? Well, we call that dark matter and dark energy! Illustration of Dark Matter Dark Matter: Earlier we thought that this universe of ours was made up of only baryons and leptons, i.e. electrons, protons, and neutrons. But subsequently, we found out that this theory was not fully accurate and only 5% of this universe is made up of visible matter. The rest 25% consists of "Dark Matter". Dark here is used because we cannot see this, yet we can only sense its presence because of its gravitational pull. We deduced that it has mass because it creates a gravitational field. An Image of a Cluster. Pink here is normal matter and blue indicates Dark matter which is overpowering the pink one.

Ever wondered how actually this universe was formed? How will it end? Why is everything in the universe so distant from each other? Is there any life on other planets? Most probably, the answers to these questions are still yet unknown and no accurate description can be found in any of the present texts. Many philosophers think of this universe as an "illusion", which means it is not accurate, just a simulation. The things we are seeing are not actually there and not in the state as we see them. Let's take a look at how we can call this universe an illusion! The Human Eye Can See Only a Part of the Electromagnetic Spectrum: We are already familiar with the electromagnetic spectrum, i.e. the division of light into different wavelengths or frequencies. Visible light, gamma rays, radio waves, microwaves, infrared rays, X-rays, and ultraviolet rays are the different regions of the electromagnetic spectrum of light. The strange part here is that the human eye can only see t
