Is it possible? Yes, of course. Since about 30 years, a phenomenon, whose origin is still unknown and which is called "cosmic rays", keeps a mystery. The cosmic rays of high energy are particles coming from somewhere in the universe and producing a great shower of particles (pions, kaons, muons, electrons, neutrinos, photons...) when collision is with the atoms of our atmosphere. While many subatomic particles, or particles that make up atoms, can only penetrate into objects a very small distance, neutrinos easily pass through an object as large as Earth. Almost all the neutrinos that reach Earth pass right through the planet. Billions of neutrinos pass through every human body every second. Some physicists think that neutrinos could be high-energy cosmic particles. But from where and how do they acquire such energy? Mystery is still open. Many astronomers believe that as much as 90 percent of the matter in the universe is dark matter (matter that does not emit light and is, therefore, invisible). Some scientists think dark matter may be exotic particles that do not consist of the atoms making up ordinary matter, as we know it. Dark matter currently cannot be observed directly, and is only detectable through its gravitational effects on visible bodies, such as the vast collections of stars known as galaxies. In some sense, this situation recalls our puzzling predicament on Earth. Today, as we have done for centuries, we gaze into the night sky from our planetary platform and wonder where we are in this cavernous cosmos. Flecks of light provide some clues about great objects in space. And what we do discern about their motions and apparent shadows tells us that there is much more that we cannot yet see as some dark matter, invisible, is orbiting around and inside the galaxies.
Moreover, a new theory for the origin of the Universe is intriguing astronomers with the idea that a "Big Splat" preceded the Big Bang. It proposes that there may be an unseen parallel universe to ours. The idea, which is still at the development stage, may provide hints about what happened before our Universe exploded into existence some 15 billion years ago. The theory has been outlined in the past few days at the University of Cambridge in the UK and the Space Telescope Science Institute in the US.
The dual nature of light seems puzzling because we have no everyday experience with wave-particle duality. Waves are everyday phenomena; we are all familiar with waves on a body of water or on a vibrating rope. Particles, too, are everyday objects—baseballs, cars, buildings, and even people can be thought of as particles. But to our senses, there are no everyday objects that are both waves and particles. Scientists increasingly find that the rules that apply to the world we see are only approximations of the rules that govern the unseen world of light and subatomic particles.
The fact that in relation to the existing things, the human beings are just like a person imprisoned in a fortress tower which has, except a few peepholes, no outlet at all. He an see through these peep-holes a river’s flowing eastward, mountains towards west, a palace towards north and a play ground towards south. In this parable the prisoner is a human being, the fortress his body and the peepholes his senses. Through the senses, he can see the colors, perceive the smell, taste the eatables, hear the sounds and feel the existence of bodies through touch. It may, however, be asked, “Is it possible to have of everything in the world?” In the parable just mentioned, the prisoner, when he looks through the peepholes cannot see anything except a small section of the river. Similarly, he can see and assimilate only a few of the colors. He cannot see the huge garden existing between the river and the mountain for the walls of the tower have no other peephole through which he could peep through. Is it justified to deny its existence simply because he does not see it. I don’t see an ant moving at a distance of three miles but it is there. There are millions of germs present in the air or in a glass full of clear water but they are invisible to me. I can see neither the atom nor the electrons revolving in its nucleus like planets in the space. Neither can I stare at the sun (for its brightness is dangerous and blinding to my naked and unshielded eye) nor 4,700,000 horsepowers of energy falling in the form of sunshine continually upon every square-mile of the earth’s surface. The sounds that an ant produces are not audible to me for the ear is receptive only to vibrations with a frequency ranging from five to twenty thousand cycles per second. The vibrations with lesser energy are not audible to me and those with bigger energy will deafen me forever.
Let us see the certainty of the unseen world from another angle. Where are we during sleep? We know for certain we are not dead, yet we certainly are dead, dead as a doornail, to this world. We are oblivious even to our own bodies. Though we do live in the familiar three-dimensional world, yet actually, we must be living in some other world, possibly of four or more dimensions, which is inaccessible and invisible to us while we are awake and conscious; which is to say in the time world. What we experience in our dreams or what our dreams relate a peculiar characteristic is that our ideas of time are confused, wild and wooly just because in the dream world, our consciousness seems free to roam and we traverse thousands of miles on foot within an hour; it does not move on relentlessly at the same fixed fate as when we are awake. Moving in some unknown dimensions, there are incidents of which we dream but these occur to our great surprise in our real life later on. Does this fact not prove an outer world of four and more dimensions that can ever be revealed to the human mind? Here is a thought-provoking verse of the Holy Quran:
It is God that takes the souls (of men) at death; and those that die not (He takes their souls) during their sleep: those on whom He has passed the decree of death, He keeps back (from returning to life), but the rest He sends (to their bodies) for a term appointed; Verily therein are Signs for those who reflect. (39:42)
Dark matter is not readily visible because it neither emits nor reflects electromagnetic radiation, such as light or radio signals. Dark matter can only be detected indirectly, e.g., through the bending of light rays from distant stars by its gravity. It may consist of dust, planets, intergalactic gas formed of ordinary matter, or anything else that is not within our reach. Observations of visible matter, the only kind we can see directly, suggest that almost 90 % of the universe is, in fact, composed of dark matter. This conclusion comes mainly from the belief that something unseen (dark matter) is tugging on visible matter, making it do things the laws of motion say it should not do. All visible bodies, therefore, seem to be careening about in a dense cloud of unseen, unknown masses. These might be dark, Jupiter-sized objects, black holes, and/or some exotic forms of matter. We must choose between the realities of dark matter or admit that something is awry with our laws of gravitation and motion when they are applied on a cosmological scale.
Thus in the light of the above findings and probes the reality of all the unseen creatures like soul, angels, spirits, ghosts, Jinns and Satan is neither impossible nor incredible.
